Xiaonan and Xiaomei run a fruit shop. They want to earn more money, but they don’t want to waste unsold fruits, so they often cut off some bad fruits and eat them themselves.

However, these seemingly good fruits are the main cause of their liver cancer.

Fruit is an essential part of our daily diet.

Fruits are rich in vitamins, minerals and antioxidants, which can provide the nutrients we need, help regulate our metabolism and promote the normal operation of our body functions.

Therefore, it is very important for our overall health to choose and eat fruits correctly.

These two fruits have been included in the "cancer blacklist"

1. Rotten and moldy fruit: Even if there is only one small mildew spot, the whole fruit will be toxic.

Most fruits contain a lot of juice, sugar and nutrients, so they are an ideal environment for mold growth. When mold grows in large quantities, fruits will begin to rot gradually.

Mold is actually a big family. Usually, mold does not cause fatal harm to human body. But under some suitable conditions, the problem of mold may be more serious than we thought.

For example, in rotten fruits, the most common toxins are patulin, ochratoxin A, aflatoxin and arthrosporin.

These toxins are harmful to human health to varying degrees, and may even lead to cancer, deformity or death.

Penicillin: It can pollute all kinds of fresh fruits and juices, and can damage the intestines and kidney function. The International Agency for Research on Cancer (IARC) lists it as a class 3 carcinogen.

Ochratoxin A: It is toxic to liver and kidney, and can pollute a small number of fruits, such as rotten dried figs and apricots. IARC classified it as a class 2B carcinogen.

Aflatoxin: A strong carcinogen, it can pollute rotten fruits such as sugarcane, raisins and dried figs. IARC classified it as a class 1 carcinogen.

Arthrospermycin: It is a definite carcinogen, which can pollute rotten sugarcane. If pregnant women eat it carelessly, it may lead to fetal malformation.

Therefore, it is recommended not to eat any rotten fruit, even if the bad parts are cut off, there may be toxin residues.

2. Areca catechu: a primary carcinogen

Areca catechu is a first-class carcinogen, and this conclusion was announced by the International Center for Research on Cancer in 2003.

Chewing betel nut for a long time is equivalent to subjecting the oral mucosa to both physical and chemical blows, so that it is constantly injured.

Long-term injury is a very dangerous carcinogen, and many organ cancers are related to persistent injuries, such as lung cancer, liver cancer, esophageal cancer and so on.

In these two cases, the fruit can be eaten after cutting the wound.

1. Low temperature frostbite causes

In the low temperature storage environment, the activity of superoxide dismutase in fruits decreases, and the free radicals in cells cannot be eliminated in time.

With the increase of the number of free radicals, they will change the permeability of fruit cell membrane, thus destroying the cell structure.

In addition, the low temperature environment will also improve the activity of pectin esterase in fruit, which will decompose insoluble pectin in pulp and make the surface of fruit "soft and rotten".

But in fact, the "frostbitten" fruit is only damaged by cells and does not produce microorganisms or toxins, so it can continue to be eaten.

2. Bumped and crushed fruit

In the process of collision, the cytoplasm in the fruit dissolves, and the colorless phenols in the cells are transformed into colored quinones.

In essence, these fruits are not infected by harmful pathogens such as bacteria, so short-term eating will not affect the body.

Of course, if the fruit in your house has been stored for a long time, and it is not clear what caused it to be "a little rotten", it is better to throw it away.

CCTV News:According to the news of the State Commission for Discipline Inspection of the Central Commission for Discipline Inspection on July 4th, Wang Baoping, a member of the former party group of Hubei Provincial Department of Natural Resources and the former head of the discipline inspection and supervision team of Hubei Provincial Department of Discipline Inspection and Supervision, was expelled from the Party membership and public office after the Hubei Provincial Commission for Discipline Inspection and Supervision filed an investigation and submitted it to the Hubei Provincial Party Committee for approval.

The public resume shows: Wang Baoping, male, Han nationality, born in March 1968, born in Zhongxiang, Hubei Province, holds a postgraduate degree.

For nearly 20 years from 1995 to 2015, Wang Baoping has been working in the prison management system of Hubei Province: starting from the deputy director of the Education Department of Hubei Prison Administration, and then being promoted to the head of the Political Research Department of the Office of Hubei Prison Administration; Two years later, he served as deputy director of the comprehensive information department of Hubei Provincial Prison Administration; From September 2003 to December 2010, for more than seven years, Wang Baoping served as the director, deputy secretary and secretary of the Party Committee of Hanyang Prison respectively. From December 2010 to February 2015, he served as secretary of the Disciplinary Committee and member of the Party Committee of Hubei Provincial Prison Administration. From February 2015 to November 2018, he served as the head of the discipline inspection team of the Hubei Provincial Commission for Discipline Inspection and a member of the party group of the Hubei Provincial Department of Land and Resources; The official career stopped at the head of the discipline inspection and supervision team of the Hubei Provincial Commission for Discipline Inspection and the member of the party group of the Hubei Provincial Department of Natural Resources.

Wang Baoping was in charge of Hanyang Prison for nearly 8 years. What did he do during these years? The Supervision Committee of Hubei Provincial Commission for Discipline Inspection gave the answer — — According to the report, Wang Baoping took advantage of the position of the then prison director to directly or instruct the prison police to help criminals who organized and led crimes committed by underworld organizations in terms of exemption from punishment, giving rewards, reporting for commutation, adjusting prisons, etc., and acted as a "protective umbrella" for evil forces. It also seriously disrupted the supervision order, caused adverse social impact, and was suspected of abuse of power; Accepting a request, fabricating facts, forging important meritorious service materials, and reporting for commutation of sentence for criminals sentenced to life imprisonment in violation of regulations, suspected of practicing favoritism and reducing sentence.

As the penalty executing organ of the country, prison shoulders the functions of imprisonment, reform, management and education for criminals, and is by no means a place for criminals to enjoy their lives. According to the circular, Wang Baoping abused his power, befriended criminals who served prison sentences and led underworld organizations, and acted as their "protective umbrella", which seriously disrupted the supervision order and undermined the political ecology of the prison management system in the province. Wang Baoping instructed prison police officers to give rewards to criminals involved in black crimes, report for commutation, and even forge major meritorious service materials to help criminals involved in black crimes get free punishment and commutation. He regarded the power of law enforcement in his hands as a privilege for personal gain, abused power and perverted the law, connived and encouraged the arrogance of evil forces, seriously damaged the image and prestige of law enforcement agencies, and was severely punished, which was really self-inflicted.

During the Spring Festival of 2011, that is, after Wang Baoping just left Hanyang Prison and was promoted to the position of Secretary of Discipline Inspection Commission and Party Committee member of Hubei Prison Administration, a sensational case was exposed in Hanyang Prison. According to the Legal Evening News, dozens of prisoners serving their sentences in Hanyang Prison, Hubei Province, reveled: they got together to drink and gamble collectively, and showed the yellow video &hellip in the lobby on the first floor; … All this was secretly filmed by Li, a prisoner, with MP5 illegally brought into the prison area, and brought out by his mother when she visited the prison to blackmail the prison. The duration of the two videos is 52 minutes and 13 minutes respectively. For the above scenes, Chen Yi, the supervisor of the Ninth Ward of Hanyang Prison, actually said that he "didn’t see" during the inspection.

The circular issued by the Supervision Committee of Hubei Provincial Commission for Discipline Inspection has harsh wording, which is an accurate "portrait" of Wang Baoping’s violation of law and discipline: as a leading cadre in party member, he has lost his ideals and beliefs, has no party spirit principle, is disloyal and dishonest to the party, and is duplicitous in appearance. In violation of political discipline, Wang Baoping bought and read books that distorted and attacked the party’s organizational line and cadre policies at the 18th National Congress, and did not report, resist or fight WeChat articles, pictures and videos that violated the Four Cardinal Principles and other serious political issues, and forwarded them to others, causing adverse effects.

On February 28th, the website of the State Supervision Commission of the Central Commission for Discipline Inspection issued a document "Teach you to recognize these" two-faced people ",pointing out that" (they) have a set of faces, a set of backs, a set of words and a set of actions ",and some" two-faced people "are" pretending to be very upright, hiding deeply and having strong concealment and confusion ". This paper lists four typical "two-faced people", one of which is Wu Dehua, former member of the Standing Committee of Chongqing Yubei District Committee. In front of people, he "always talks about his firm communist ideals and beliefs, but secretly joins feudal superstitious organizations without telling the party organizations, and also attempts to create his own fallacies and apply divination to his work and life." In his own words, it means "I lost my political beliefs and lost my political soul and spiritual pillar." In addition, He Jian, former member of the Standing Committee of the Honghe Prefecture Committee of Yunnan Province and secretary of the Political and Legal Committee, was also criticized as a typical "two-faced person", which was manifested in "talking about the future and destiny of the country, but secretly complaining and resenting the organization when he met his personal reputation". Then there is Du Xiaoyang, the former deputy secretary of the Party Committee and president of Chongqing Vocational College of Safety Technology. The problem lies in "kowtowing, flattering and sycophanting before the leaders.In front of subordinates and the masses, they are arrogant, arrogant and arrogant. "

"Resolutely oppose double-dealing, double-dealing", the report of the 19th National Congress of the Communist Party of China has a very clear attitude on the issue of opposing double-dealing. Unswervingly and strictly administering the Party in an all-round way, it is necessary to recognize, guard against and eliminate the double-faced, so that party member and cadres will always be loyal and honest to the Party. In the face of party discipline and rules, no one can be lucky.

General Secretary of the Supreme Leader pointed out: "Health is an inevitable requirement for promoting people’s all-round development, a basic condition for economic and social development, an important symbol of national prosperity and national prosperity, and the common pursuit of the broad masses of the people."

With the continuous progress of building a healthy China, people’s health level has been continuously improved. By the end of the Thirteenth Five-Year Plan, China’s average life expectancy has increased to 77.3 years, and the main health indicators are better than the average level of middle-and high-income countries. The medical service and support capabilities have been continuously improved, and the physical quality and health literacy of the whole people have been continuously enhanced.

Over 7700

Hospitals above the second level that provide online services.

Lao Zhang from Guizhou is 64 years old. More than a year ago, he often had symptoms such as general weakness, chest tightness, shortness of breath and chest pain. He was diagnosed with tuberculosis after examination in a local hospital. In May 2021, Lao Zhang went to Hunan Chest Hospital for treatment accompanied by his family. The hospital organized an expert group to treat Lao Zhang with anti-tuberculosis and nutrition enhancement. Lao Zhang’s condition improved rapidly and his body gradually recovered. "I can walk now, especially thanks to the careful treatment of medical staff!" Lao Zhang’s daughter said excitedly.

China’s medical service capacity has been continuously improved, which can basically meet the medical needs of the broad masses. From January to October 2021, the total number of medical and health institutions in China reached 5.44 billion, a year-on-year increase of 23.4%. The utilization rate of hospital beds in China was 75.1%, up by 3.2 percentage points year-on-year.

National Health Commission has launched the "Action Plan for Further Improving Medical Services" for six consecutive years, striving to make medical treatment safer, more convenient, more effective in communication and more comfortable in experience. The majority of public hospitals further facilitate the majority of patients to seek medical treatment through the application of information technology, the provision of intelligent services, and the aging transformation. The data show that by the end of 2020, 51.2% of public hospitals with secondary and above have made appointments, 91.6% have carried out clinical pathway management, 63.2% have carried out telemedicine services, 86.7% have participated in mutual recognition of examination results at the same level, and 93.7% have carried out quality nursing services.

In recent years, "Internet+medical service" has run out of acceleration. By the end of 2018, there were only over 100 Internet hospitals. By June 2021, the number of Internet hospitals has soared to 1,600, and more than 7,700 hospitals above the second level provide online services. Third-party platforms have opened Internet medical services, further facilitating patients.

"Healthy China 2030" Planning Outline puts forward the goal of greatly improving health service capacity by 2030: a high-quality and efficient integrated medical and health service system and a perfect national fitness public service system are fully established, the health security system is further improved, the overall strength of health science and technology innovation ranks among the top in the world, and the quality and level of health services are significantly improved.

79 years old

Life expectancy per capita in 2030

At the end of 2021, the hemodialysis center of zhuoni People’s Hospital in Gannan Tibetan Autonomous Prefecture was officially opened, with 1 deputy chief physician, 2 assistant physicians and 8 nurses. The newly-built hemodialysis room is fully equipped. "It will be convenient to do treatment in the future." The patient, Lao Ma, said that in the past, dialysis was a time-consuming, costly and laborious task.

In the early days of the founding of New China, China’s medical conditions were extremely backward, and medical and health resources were mainly concentrated in big cities. Data show that at that time, there were only 3,670 medical and health institutions and 505,000 health technicians in China.

Nowadays, China’s medical and health resources have undergone earth-shaking changes. By the end of October 2021, the number of medical and health institutions in China was 1.038 million. Compared with the same period of last year, there were 872 hospitals and 12,745 primary medical and health institutions.

The leap-forward development of medical and health resources can not be separated from continuous funding. In recent years, China has continuously increased financial input in the field of medical and health care. In 2020, the total national health expenditure will reach 7,217.50 billion yuan, and the per capita health expenditure will be 5,112.3 yuan. Among them, government health expenditure was 2,194.19 billion yuan, social health expenditure was 3,027.37 billion yuan, and personal health expenditure was 1,995.94 billion yuan, and the proportion of personal health expenditure continued to decline.

The outline of the "14th Five-Year Plan" proposes to adhere to the public welfare nature of basic medical and health undertakings, take the improvement of medical quality and efficiency as the guide, take public medical institutions as the main body and non-public medical institutions as the supplement, and expand the supply of medical service resources. The "Healthy China 2030" Planning Outline proposes that the average life expectancy will reach 79 years in 2030. In the future, as China’s high-quality medical and health resources are further enriched and medical resources are more abundant, people’s health level will be further improved.

Over 60%

Signing rate of family doctors in key population

In 1967, 16-year-old Ma Wenfang became a "barefoot doctor" in Suliuzhuang Village, Dagang Li Township, Tongxu County, Kaifeng, Henan Province. Today, the village clinic has achieved standardized construction, and Ma Wenfang has become a family doctor. The villagers signed by Ma Wenfang are mainly residents over the age of 65 who suffer from diseases such as hypertension, diabetes and coronary heart disease. China began to implement family doctor contract service in 2017, and now the contract signing rate of key groups has exceeded 60%.

The establishment of county and village three-level medical system and rural cooperative medical system in China has been recognized by the World Health Organization. In 2009, China launched a new round of medical and health system reform, and rural medical and health conditions were further improved. By the end of October 2021, there will be 985,000 grass-roots medical and health institutions nationwide, including 36,000 community health service centers (stations), 35,000 township hospitals, 272,000 clinics (infirmary) and 608,000 village clinics.

The construction of county medical community has been accelerated, and the rural medical service capacity has been continuously enhanced. In April 2017, the General Office of the State Council issued the Guiding Opinions on Promoting the Construction and Development of Medical Consortium, proposing to set up a medical community in the county, give full play to the role of county-level hospitals as a link between urban and rural areas and a leading role in the county, form a division of labor and cooperation mechanism for county-level medical and health institutions, and build a three-level linkage county-level medical service system. Through more than four years of exploration and construction, the number of county medical communities in China has increased rapidly: by the end of March 2021, China had built 4028 county medical communities.

The "14th Five-Year Plan" outlines that high-quality medical resources in provinces and cities should be promoted to support the development of county-level hospitals, and 500 county-level hospitals (including traditional Chinese medicine hospitals) should be added to meet the facilities and service capacity of tertiary hospitals. We will steadily expand the coverage of contracted services for urban and rural family doctors and improve the quality of contracted services. The shortcomings of medical and health care in rural areas will be further supplemented, and rural residents will get more benefits from medical treatment. (Reporter Shen Shaotie)

　　BEIJING, Beijing, May 21 (Reporter Liu Yuying) The "White Paper on Blockchain Industry in China in 2018" released by the Information Center of the Ministry of Industry and Information Technology of China on the 20th said that the blockchain industry in China is in a high-speed development stage and the industrial chain has taken shape.

　　According to the White Paper, by the end of March 2018, the number of blockchain companies with blockchain business as their main business in China had reached 456, from upstream hardware manufacturing, infrastructure and security services to downstream industrial technology application services, to industry investment and financing, media and talent services to ensure industrial development. Companies in various fields have been basically complete, coordinated and orderly, and jointly promoted the industry to move forward.

　　Judging from the geographical distribution of the company, the geographical distribution is relatively concentrated and the industrial agglomeration effect is obvious. Beijing, Shanghai, Guangdong and Zhejiang are still concentrated places for blockchain entrepreneurship, and blockchain enterprises in the four provinces account for over 80%. In addition, China’s top ten provinces with blockchain entrepreneurial activity include Jiangsu, Sichuan, Fujian, Hubei, Chongqing and Guizhou.

emergency food（emergence food，EF）It refers to a kind of food used to maintain human survival in emergencies such as disasters, wars and crashes. Common emergency foods mainly include earthquake relief emergency foods, military emergency foods, civil emergency foods and M9 outdoor emergency foods. Due to the late start of research and development,There is still a certain gap between China’s emergency food and developed countries such as the United States and Japan in processing and packaging, nutritional characteristics, food safety and other key technologies.

At present, the problems caused by the insufficient development of emergency food have initially appeared. First of all, during or after natural disasters, food in disaster areas and other affected areas may be contaminated by microorganisms and chemicals, and some food-borne diseases, including hepatitis A, typhoid fever and a series of intestinal diseases, such as cholera and dysentery, are prone to break out, thus affecting the health of victims and the effect of disaster relief.

Secondly, due to the imperfect design of emergency food formula,Its nutritional structure is difficult to meet the nutritional supply needs of specific people.It is difficult to predict the time and place of some emergencies, which also leads to the traditional supply chain processing equipment and storage and transportation system can not meet the stable supply and accurate distribution of emergency food, which makes the rescue efficiency decline.

This paper summarizes the types and characteristics of emergency food, the development status of product development, storage and transportation, processing and packaging technology, and looks forward to the research and development strategy, processing, storage and transportation strategy and food safety of emergency food in order to provide new ideas for the development of emergency food industry in China.

Types and characteristics of emergency food

With the frequent occurrence of emergencies around the world, the demand for emergency food is increasing. In order to better meet the nutritional needs of different rescue scenes and people, and combined with the laws of emergency food diversity, high energy density, storability and convenience for eating, a variety of common emergency food types have appeared in recent years, including canned food, compressed dry food, instant hot food, dehydrated food, etc. The advantages and disadvantages of different types of emergency food are shown in Table 1.

Table 1 Advantages and disadvantages of different types of emergency food

Emergency food has the following characteristics:

(1) Long shelf life: Emergency foods usually have a long shelf life to ensure edibility in emergency situations;

(2) Rich nutrition: under the premise of meeting basic energy, emergency food pays more attention to the functionality and special dietary effect of food according to the needs of the target rescue population;

(3) Portable: Emergency foods are usually packaged in light packages to quickly respond to emergencies;

(4) Food safety: Due to the harsh and changeable emergency rescue environment, the food safety of emergency food is very important.

When selecting emergency food types, it is necessary to make reasonable selection and planning according to disaster types, storage conditions, crowd demand and transportation environment. At the same time,Emergency food should be inspected and updated regularly to ensure food safety.

Development status of emergency food products

In recent years, China’s emergency food has developed steadily in terms of shelf life, taste, flavor and safety, but there is still a big gap compared with foreign countries. The shortcomings include:

(1) Low comprehensive performance. The diversity, nutrition and safety of emergency food need to be further strengthened;

（2）Functional development is limited.Due to the lack of practical experience in functional development and the lack of clear supervision and guidance standards, it is difficult for enterprises to carry out effective innovation and development;

（3）The production cost is high.The research and development of key technologies and formulas of emergency food are lagging behind and the added value is low, which leads to its lack of core competitiveness and affects production costs.

With the increasing market demand for serialized, functional, long shelf life and full nutrition emergency foods, continuous optimization, innovation and enrichment of R&D categories have become the key to the development of emergency foods.

With the development of science and technology,Emergency food is paying more and more attention to functions other than satiety and special dietary effects.Adding some ingredients or nutrients with special physiological functions to raw materials can enhance the overall functionality of emergency food.

At present, China’s self-developed "China 05 compressed food" has many functions, such as improving intestinal health, fighting hunger and promoting physical recovery, which greatly improves the efficiency of emergency rescue. Internationally, the United States has successfully developed military functional foods with different functions, such as anti-altitude sickness, anti-fatigue, refreshing the mind, quickly replenishing energy, improving intestinal function, etc. In order to meet the needs of different groups of people, modular foods with mineral modules, vitamin modules and energy modules have also been developed. Japan’s One Table Company has developed an emergency rescue jelly that is beneficial to swallowing, taking into account the people of all ages, so as to meet the needs of the elderly and children for quick nutrition supplement.

High-intensity rescue work in emergency rescue often makes rescuers in a state of physical and mental fatigue and overwork, which leads to inattention, weakened resistance and reduced work efficiency. Therefore,It is necessary to develop emergency food to delay or eliminate fatigue.

Hao Limin and others designed an anti-fatigue beverage formula, which was composed of oligosaccharides, taurine, caffeine, effervescent and other materials. It was processed into effervescent tablets by mixing, granulating, drying, cooling and tabletting. The animal test results showed that the beverage had obvious anti-fatigue effect. Wu Tianyi et al. conducted related research on anti-hypoxia functional fermented products. Through the screening of animal anti-hypoxia tests, it was found that natto and Schizophyllum commune fermented products from microorganisms had significant anti-hypoxia function, which provided a new design idea for the development of anti-hypoxia functional emergency food in the future.

Research status of emergency food storage, transportation and processing technology

In 2003, China began to pay attention to the research on emergency food storage and transportation, and compared with foreign countries, the research started late. In the "storage and transportation" system, food is generally classified and food quality standards are formulated to ensure food quality, facilitate transportation and improve rescue efficiency.The key to the efficient operation of the storage and transportation system lies in making full use of the electronic information platform.Ensure the coordination and mutual supervision of all links, strengthen the contact between emergency food storage and transportation and electronic information enterprises, so as to improve the rapid response ability of emergency food storage and transportation.

At present, there are many researches on food supply chain at home and abroad, covering the supply chain research of various specific food categories, such as fruits, vegetables, grain, etc. However, the research on emergency food logistics is rarely reported. The problems existing in the existing emergency food storage and transportation system in China are mainly summarized as the following four points:

(1) The layout of emergency material reserve centers around the country is unreasonable;

(2) Due to the asymmetric information flow and the large number of relief materials transfer stations in emergencies, the supply imbalance is prone to occur;

(3) Lack of procurement and operation standards for emergency food storage and transportation;

(4) The improvement of food safety evaluation system in the process of emergency food storage and transportation is not perfect, and the efficiency needs to be improved.

Compared with emergency food in developed countries,Domestic emergency foods generally have the problems of short shelf life and low scientific and technological content.The shelf life of self-heated rice and freeze-dried meat products introduced by American Mountain House Company can reach 30 years. The emergency food supply package launched by Wise Company is not only convenient and fast, but also can meet the needs of families, and its shelf life is as high as 25 years. In contrast, the shelf life of emergency food made of domestic Changwo special food by freeze-drying technology is not half as long as it is.

This shows that in the future, the development of emergency food in China should be oriented towards using emerging technologies to maintain the shelf life of food, thus developing a sustainable food value chain and limiting food waste. In order to prolong the shelf life, optimize the taste and promote nutrient absorption,More and more emerging processing technologies have potential application value.

1. Vacuum freeze-drying technology

Vacuum freeze-drying is to freeze the material below the eutectic point and remove the water in the material by sublimation in vacuum environment, so as to achieve the purpose of freeze-drying.It is common in military emergency food, which is used to improve the retention rate of nutrients and maintain the original color and flavor.Vacuum freeze-dried food can be stored at room temperature for a long time without adding preservatives because of its low water activity, and it is convenient to carry and transport.

Yang et al. used hot air drying, hot air vacuum combined drying and vacuum freeze-drying to dry the velvet antler mushroom. The results showed that vacuum freeze-drying could better keep the color and shape of velvet antler mushroom. However, vacuum freeze-drying has the disadvantages of time-consuming, energy-consuming and high cost when used alone, and these problems can be effectively solved by combining with other drying technologies.

Jiang et al. evaluated that freeze-drying combined with microwave vacuum drying was used to dry functional okra snacks. Compared with freeze-dried samples, the combined drying samples had better hardness and brittleness, and the drying time and energy consumption were reduced by about 75.36% and 71.92% respectively. Therefore,Vacuum freezing combined with vacuum microwave drying can be one of the development directions of emergency food drying.

2. Ultra-high pressure technology

Emergency food needs to have a long shelf life to ensure the safety and edibility of food in an emergency. Ultra-high pressure technology uses high pressure force to act on food,Without using high temperature or chemical additives, the shelf life of food can be prolonged by killing microorganisms and inhibiting enzyme activity, while maintaining the original flavor, color and nutrition of food.

Compared with traditional high-temperature treatment, ultra-high pressure technology hardly reacts with covalent bonds of small molecules, and only destroys non-covalent bonds that form the three-dimensional structure of macromolecules, such as hydration, ionic bonds and hydrogen bonds. By inactivating or activating biomolecules such as polysaccharide and protein in food, the product quality can be improved. It is found that soaking and ultra-high pressure pretreatment can increase the content of fast digestible starch and slow digestible starch in rice starch, and reduce the content of resistant starch, thus improving the digestion characteristics of rice.

It should be noted that ultra-high pressure sterilization technology is not suitable for all types of food, and the composition and structure of different foods have different sensitivity to pressure, so it should be tested according to specific products to determine the best treatment scheme.

3. Ultra-fine grinding technology

Ultra-fine pulverization technology pulverizes material particles to micron level by mechanical or hydrodynamic force, thus reducing particle size, changing composition and internal structure, and improving physical and chemical properties of materials. For example, ultrafine grinding canIncrease the solubility of foodSo that it can be easily dissolved with water or other liquids in a short time and quickly prepared into food; In addition, it can alsoEnhance the digestibility of foodSo that it can be absorbed and utilized by the human body in a short time and provide energy quickly, and reduce the burden on the gastrointestinal tract.

Sun et al. treated dehydrated celery stems with superfine grinding technology, and found that there was no significant difference in chemical composition of celery powder with different particle sizes. However, with the decrease of particle size of celery stem powder, its ability of scavenging free radicals was continuously enhanced, which provided a reference for developing fast-dissolving antioxidant functional foods. Zhang et al. treated oat bran by ultra-fine pulverization technology, which improved the surface properties, water holding capacity and swelling capacity of oat bran. The prepared oat bran powder has good physical and chemical properties and oxidation resistance. The data obtained from this study provide theoretical basis for the application of ultra-fine pulverization technology in emergency food deep processing and functional food development.

4. Microcapsule technology

Microcapsule technology is a new packaging technology, which forms a delicate and tough shell around liquid or solid core materials, so that the core materials can be packaged inside the shell. Nutrient fortification is a common technology to improve the nutrition of emergency food. However, many nutrients or functional components such as vitamins, probiotics and antioxidants are prone to degradation, oxidation and volatile loss during production, storage and transportation due to their unstable physical and chemical properties.Using microcapsule technology to embed nutrients and functional components can play a protective role, reduce the influence of external environment such as light, heat and oxygen, and at the same time make them be digested and absorbed when needed.Improve the nutritional value of emergency food.

The results show that adding microencapsulated nutritional fortifier ferrous sulfate to flour can mask the iron smell and avoid the rancidity of oil caused by direct addition. Das et al. successfully prepared anthocyanin extract from purple rice bran with modified glutinous rice starch as wall material by spray drying technology. Microencapsulation showed that the surface of microcapsules was more uniform and smooth than natural starch and modified starch, and the storage stability of microencapsulated anthocyanins was improved. Generally speaking, microcapsule technology provides a new possibility for emergency food, which can improve the taste and prolong the storage time while ensuring nutrition and convenience.

5. Nanotechnology

Nanotechnology can be used to enhance the nutritional value of food and improve its functional components. For example, processing nutrients to less than 100nm by nanotechnology can improve the absorption and utilization rate of nutrients by human body, which can solve the pain point problem that emergency food has low moisture content and is not easily absorbed and utilized by human body.

Nanotechnology can also improve the texture, taste and flavor of food, and be used to remove harmful pollutants in food, such as pesticide residues, heavy metals and harmful chemicals. The special properties of nano-materials enable them to adsorb or catalyze the degradation of these pollutants and improve food safety. However, the application of nanotechnology in food processing is still in its infancy. In the future, when nanotechnology is applied to emergency food, it is necessary to carry out risk assessment and strict supervision on the safety of nanomaterials to ensure the sustainable development of nanotechnology and food safety.

Research status of emergency food packaging technology

Food packaging is a very important processing link that affects the quality of emergency food. As a barrier layer of food, it can protect food from adverse factors such as external environment, microorganisms and pollutants, maintain food freshness, hygiene and safety, and extend its shelf life.Emergency food is usually stored by sealing, modified atmosphere and vacuum packaging. The packaging forms include vacuum aluminum foil packaging, composite nanotechnology packaging and edible film packaging.

In 2016, China developed the world’s first compressed packaging of disaster relief emergency food. By using this pre-foldable compressed packaging food, each logistics vehicle can carry 50% more goods, and the transportation and supply of disaster relief food is more efficient and faster, and the transportation cost is lower. In recent years, in order to prolong the shelf life of food and ensure the quality and safety of food, a variety of functional food packages have appeared in the market, such as antibacterial packaging that inhibits the growth of microorganisms, intelligent packaging that monitors the quality of food, and biodegradable environmental protection packaging.

1. active packaging technology

Active packaging is defined as an intelligent system, which aims to extend the shelf life and improve the quality of food through the interaction between packaging materials and the internal environment of food, so as to meet consumers’ demand for fresh, stable and safe food. Active packaging mainly includes antioxidant packaging and antibacterial packaging. Among them, antioxidant packaging can prevent food from deteriorating by absorbing oxygen or releasing carbon dioxide in the packaging, thus prolonging the shelf life of food. Common oxygen adsorbents include ethylene adsorbent, iron powder, activated carbon, biological enzyme and so on.

Antibacterial packaging mainly inhibits the growth of pathogenic and corrosive microorganisms in food by introducing antibacterial agents, prevents the migration of pollutants, and can also show the leakage of some packaging, thus ensuring food safety. These active packaging technologies provide a broader design idea for future emergency food packaging,So that it is no longer limited to dehydration and drying, and fresh food with better experience can be selected.

2. Nano packaging technology

Nano-technology involves the development of single or multi-dimensional materials less than 100nm. Studies have confirmed that packaging materials with nano-size have large specific surface area and small pores, which can effectively isolate the invasion of external gas, moisture and pollutants, prolong the shelf life of food and reduce the loss of food. In addition, the nano-packaging material has excellent mechanical properties,Can give packaging materials high mechanical strength and durability, and is suitable for use in harsh emergency environments.Therefore, nano-materials are expected to improve the mechanical and barrier properties of emergency food packaging.

On the other hand, the surface of nano-materialsAntibacterial agents such as nano silver can also be added to inhibit microbial growth and reduce food pollution and corruption.Thereby improving the safety of food. Compared with ordinary antibacterial packaging, nano-packaging has stronger anti-corrosion and fresh-keeping function, and is less affected by various extreme weather. In the future, with the continuous development of nanotechnology, nano-packaging materials are expected to provide better protection and quality control for emergency food, and ensure that people can get high-quality food supplies in emergencies.

3. RFID packaging technology（RFID）

RFID is a technology to automatically identify objects by using radio waves. Identification is accomplished by storing serial numbers or other information on a microchip connected to an antenna. Based on wireless communication, RFID can provide real-time information about temperature, relative humidity, nutrition and supplier information in the process of products passing through the supply chain, improve traceability and ensure food quality and safety.

The application of RFID in the field of military food packaging mainly focuses on the storage and transportation stage. By adding RFID tags to military food packaging, the whole process information tracking of military food in the distribution process can be realized through the one-object-one-code identification function of tag chip. In case of emergency, the whole distribution process needs no unpacking, and all the information of the product can be obtained directly by scanning the reader, including the processing information, storage status, transportation information and eating methods of the product, so as to realize the rapid and accurate replenishment of emergency food and improve the speed and accuracy of distribution.

At present, RFID technology has been widely used in the field of civil food packaging, and these experiences can be used for reference in the field of emergency food packaging.Realize the whole process tracking and management of emergency food supply chain, and improve the efficiency and quality of emergency food distribution.

4. Time-temperature indicator technology（TTI）

TTI technology aims to monitor the temperature changes in the food supply chain to predict the changes of food heat-sensitive nutrients and indicate the remaining shelf information of products, thus reducing food consumption and ensuring food safety. The basic working principle of TTI technology is based on the changes of machinery, chemistry, electrochemistry, enzymes or microorganisms, which are usually manifested as visible reactions in the form of mechanical deformation, color development or color movement. It can monitor and record some key parameters in the whole food distribution process,By combining the cumulative effect of time and temperature, the remaining shelf life of the product is dynamically displayed.In order to monitor the cumulative effects of time and temperature on specific products, TTI labels are usually attached to food packaging.

Compared with other temperature monitoring equipment, TTI is small in size and cost-effective, and can reflect the time and temperature changes experienced by food by displaying irreversible effects that are easy to observe. At present, the packaging method of emergency food usually follows the date of production, and the date of production and the time limit for eating are printed on the outer packaging. However, in an emergency situation, the quality and safety of food become particularly important due to the instability of storage and transportation environment. By using TTI technology, the quality and safety of emergency food can be better monitored and controlled, and whether the food has been infringed by the external environment can be found in time, which provides great guarantee for enhancing the safety of emergency food.

5. Edible packaging membrane technology

Edible packaging film refers to the packaging film with porous network structure formed by intermolecular interaction with edible materials such as protein, grain matrix, cellulose and other raw materials, supplemented by edible crosslinking agents, plasticizers and other substances.This packaging material can not only effectively protect food quality, but also reduce environmental pollution.

For example, the grain matrix film is usually made of soybeans, which is safe and harmless. At the same time, the packaged products also have the effect of moisture-proof and moisture-proof, which has a good effect on improving the quality of fresh-keeping foods. Compared with traditional packaging materials, edible packaging film has the characteristics of edibility, and it will not produce packaging waste after use, reducing the negative impact on the environment, making edible packaging film a more environmentally friendly choice.

Edible packaging film has a potential application prospect in the field of emergency food, which can provide good food protection and preservation effects, while reducing the generation of packaging waste. However, when edible packaging technology is applied to emergency food in the future,It is necessary to evaluate the stability and performance of this technology under various environmental conditions.

6. Biodegradable packaging technology

With the continuous development of new technologies and new resources, it is another research direction with great potential to use degradable, energy-saving and emission-reducing packaging materials instead of high-energy and refractory packaging materials. At present, researchers have done a lot of research on degradable packaging materials, and their barrier properties need to be improved when they are used in emergency food in the future.Designed as a biodegradable high barrier material.

Microfiberized cellulose material（microfibrillated cellulose，MFC）It is a biodegradable and widely used high-performance material, which usually comes from green beet pulp, bagasse and soybean skin, and is composed of a large number of cellulose microfibril aggregates. Lavoine et al. reported that microfibrillated cellulose materials and plastic film materials can be combined to form nano-composite packaging materials. Through surface chemical modification, the shortcomings of MFC materials in barrier performance and oxygen barrier performance were solved. However, due to the hydrophilic characteristics of bio-base, the moisture resistance of MFC nanocomposites needs to be further studied and improved.

In the future, intelligent packaging technology can be adopted to optimize the packaging barrier performance and design biodegradable multiple high barrier materials.

Prospect of emergency food development strategy

With the frequent occurrence of natural disasters and the increase of emergency situations, the complexity of rescue site environment and the diversification of rescue people, the development of emergency food in the future needs to introduce advanced scientific and technological innovation technology. For example, the use of Internet of Things technology, intelligent warehousing, scientific packaging technology, etc., to achieve traceability and monitoring of emergency food, improve the quality of emergency food and rescue efficiency. In addition, through the dimensions of raw material screening, formula design, texture reorganization, packaging design, etc., emergency foods in different scenes and target groups are developed to accurately match the nutritional needs of specific groups, increase their acceptance and satisfaction in emergency situations, and improve the quality and effect of emergency response.

1. Future research and development strategy of emergency food

Future emergency food is a kind of food that can quickly and accurately match the nutritional needs of specific people according to different emergency situations, and is convenient for transportation and storage. Based on the research results of emergency food in various countries, the future research and development strategy of emergency food in China can be carried out from three aspects: serialized emergency food, functional emergency food and high-tech application of science and technology.

1) Serialized emergency food.The serial development of emergency food is mainly adjusted and customized according to the dietary needs of different disaster environments and different people, which means developing diversified emergency food products.Including vegetarian, gluten-free, lactose intolerance and other products with special dietary needs to meet the needs of different groups of people.

To carry out the research strategy of emergency food serialization, especially for the needs of special groups such as the elderly, children and pregnant women, the following measures can be taken:

① Reasonable formula design, and develop emergency formula according to the nutritional needs and health status of special groups. For example, for the elderly and pregnant women, attention should be paid to the intake of protein, vitamins, minerals and cellulose; For children, energy requirements and digestibility need to be considered.

② Selection and treatment of ingredients. In order to meet the nutritional needs of the elderly and pregnant women, you can choose ingredients that are easy to chew and rich in protein and fiber; For children, you can choose ingredients that suit their taste and digestive system.

③ Safety and non-allergic guarantee. For pregnant women, children, the elderly and other special groups, it is necessary to ensure that food does not contain substances that may cause allergic reactions, such as peanuts, nuts, alcohol and so on.

④ Product form and packaging design. For the convenience of the elderly and children, it can be designed to be easy to open, chew and digest, and adopt easy-to-operate packaging methods, such as vacuum packaging and canned food.

2) Functional emergency food.The development of functional emergency food will pay attention to the nutritional balance of emergency food and the addition of functional ingredients, so as to meet people’s special needs in emergencies and slow down and eliminate the adverse effects of emergency conditions on human physiology or psychology. exploitationAnti-fatigue, anti-hyperreflexia, anti-anxiety, low temperature tolerance, help sleep, improve constipation and improve immunity.Functional emergency food is the focus of research and development of emergency food at present.

When natural disasters occur, they are often accompanied by water pollution, which will lead to serious gastrointestinal diseases and various infections. Studies have confirmed that bioactive substances can be used to treat some diseases, improve the function of biological systems or resist pathogens. For example, intake of polyunsaturated fatty acids can alleviate intestinal inflammation by changing intestinal flora and enhancing intestinal cell barrier function; Polyphenols such as curcumin can reduce the stress of endoplasmic reticulum, thus reducing the inflammatory response of human intestinal epithelial cells.

Previous studies have shown that intestinal inflammation can be improved not only by drugs, but also by improving dietary intake and increasing the intake of polyunsaturated fatty acids, dietary calcium and vitamin D, thus improving intestinal health.

For example, increasing the dietary fiber content in emergency food can promote intestinal peristalsis and defecation, and prevent constipation and gastrointestinal problems; Adding probiotics or fermented food can improve the balance of intestinal flora, enhance the function of immune system and reduce the risk of gastrointestinal infection; Foods rich in vitamin C and antioxidants, such as citrus fruits and vegetables, help to enhance the immune system function, improve the body’s resistance and reduce the risk of infection.

All in all,By improving the nutritional composition of emergency food, we can alleviate the intestinal problems caused by disasters and help people stay healthy in difficulties.The above measures can help to improve the health effect of emergency food on intestine, but in practical application, the preservation and storage conditions of food need to be considered to ensure the safety and nutritional value of food.

3) The application of scientific and high technology.The introduction of high technology is of great significance to the breakthrough of emergency food in shelf life, nutrition and functionality. In terms of extending the shelf life, methods such as microbial control, vacuum packaging and irradiation sterilization can be adopted. In terms of improving nutrition, nutritional enhancers or functional ingredients can be added to emergency food to enhance its nutritional value.

In terms of improving functionality, high-tech can be used to develop emergency food with specific functions, for example, adding natural antioxidants, humectants, thickeners, etc. to increase the antioxidant capacity, water retention and taste of food. In addition, the use of nanotechnology can improve the texture and taste of food. In the aspect of personalized nutrition enhancement, it can be combined with wearable equipment and sensors. According to the results of physiological testing,(such as lack of potassium or vitamin A)Form personalized demand data, send it to the processing base, and generate special nutritious fortified food made of seasoning liquid and powder through additive manufacturing.

To sum up, serialized emergency foods can meet the dietary needs of different groups of people, while functional foods pay attention to nutrition and special needs, while the application of science and technology and high technology is helpful to improve the quality stability, nutrition promotion and functional supplement of emergency foods. These strategies will promote the further development of emergency food in China in the future and ensure that people can get a safe and balanced food supply in disasters.

2. Emergency food processing storage and transportation strategy

Emergency food is an important relief material for survival under emergency conditions, which requires extremely high production environment and product quality in the supply chain.Therefore, it is necessary to establish an automatic, flexible and digital intelligent supply chain system.The following measures can be taken in the production of emergency food in the future.

1) Introduce intelligent equipment.Through intelligent sorting and cascade utilization technology of raw materials, artificial intelligence combined with deep learning of photoelectric equipment, inductive classification combined with manual assistance, the process parameters in the production process are continuously optimized, and a demand-oriented raw material supply system is established, which can realize the automation of raw material pretreatment and processing, reduce the risk of human subjective errors and cross-contamination, and achieve the effect of improving quality and reducing cost.

2) Build a flexible supply chain.Based on the production requirements of serialization, functionalization and science and technology of emergency food in the future, flexible supply chain can help enterprises optimize resource allocation and utilization, thus reducing costs. For example, according to the production demand of emergency products, enterprises promote the digital transformation of production processes to ensure product quality, efficiency and sustainable production capacity; In addition, through flexible adaptation of intelligent filling and packaging technology, we can quickly switch and adjust product specifications and packaging methods, so that enterprises can quickly respond to changes in market demand and improve emergency rescue efficiency.

3) Establish a digital monitoring system.By introducing precise temperature control technology and RFID technology, the key parameters of the process, such as temperature, humidity, flow rate and speed, can be collected in real time by sensors and monitoring equipment, so that the abnormal situation can be adjusted in time to ensure that the products meet the standard requirements. At the same time, considering that the time and place of emergencies are difficult to predict, the joint application of the Internet of Things and smart packaging technology can track the location, transportation conditions and quality of emergency food in real time, and combine with the logistics management system to carry out intelligent distribution and route optimization in real time according to the changes of disaster situation, so as to achieve the best transportation efficiency and save costs.

Different from ordinary food, the demand for emergency food will be affected by various factors.In the future, the development of emergency food should adopt modular design, that is, food should be grouped and packaged according to function or proportion, so that people can choose and combine different types of food according to their needs.And ensure the balanced nutrition of food. Modular design of emergency food has the advantages of flexible selection, balanced nutrition, easy carrying and storage, and improved emergency response flexibility, which can play an important role in future emergency rescue.

3. The prospect of emergency food safety.

There are some harmful substances such as mycotoxins, heavy metals and allergens in the production, processing and transportation of emergency food.It is of great practical significance to establish an emergency food quality management system, analyze the potential hazards in the production process and continuously monitor them.

In recent years, the rapid nondestructive detection technology of food and food raw material hazards has been widely used in the field of food detection and sorting, such as multi-spectral imaging technology, hyperspectral imaging technology, terahertz spectral imaging technology and so on. Because it is simple, rapid and nondestructive, and can obtain the image and spectral information of the detected substance at the same time, it has potential application prospects in food quality and safety detection, mainly including variety identification, adulteration analysis, quality and hazard detection and a series of applications.

Shi et al. realized the rapid nondestructive detection of Fusarium graminearum and vomitoxin in wheat by multi-spectral imaging technology, and explored a new method for monitoring mycotoxin pollution in wheat production, processing and storage. Liu et al. can monitor zearalenone in corn quickly and non-destructively through multi-spectral imaging combined with machine learning technology.（ZEN）The content of mycotoxin is of great significance to the monitoring of mycotoxin pollution during corn storage and transportation.

Du et al. realized the rapid detection of Staphylococcus aureus enterotoxin B in milk by Raman spectroscopy and stoichiometry, which ensured the safety of milk. Liu et al. quickly determined the concentrations of aflatoxin B1 and benzopyrene in soybean oil by terahertz spectroscopy combined with chemometrics, which provided an effective means for food safety monitoring.

In addition, harmful substances, microbial contamination and chemical residues in food processing seriously affect the quality and safety of food. Therefore, through the rapid detection technology of food hazards in the processing process, it can help manufacturers to respond quickly and reduce or avoid unqualified production operations.

Traditional on-line detection technology often has some shortcomings, such as requiring large equipment and professional operators, and complicated pretreatment.Electrochemical detection methodIt has the advantages of high sensitivity, quick response, real-time monitoring and selectivity. By measuring and analyzing electrochemical signals such as current and voltage in food raw materials, it can be judged whether there are harmful substances.

Gao et al., from the perspective of electrochemical detection, used the electrolyte gate-controlled graphene transistor with two-dimensional graphene as the channel material to realize the rapid identification of the freezing and thawing degree of beef. Mao et al. aim at heavy metal Cr in aquatic products（VI）In order to solve the pollution problem, two-dimensional monatomic iron material is used as the colorimetric sensor of peroxidase to detect Cr in fish quickly and simply.（VI）, and achieved good expected results. Zhu et al. developed a portable aptamer sensor, which has the characteristics of simple operation and portability, and can simultaneously detect T-2 toxin and zearalenone in corn and oat flour, thus realizing the on-line detection of mycotoxins during processing.

In the future, multi-functional electrochemical biosensors and nano-devices can be constructed through electrochemical aptamer joint detection technology, so as to realize the detection of complex hazards such as benzopyrene and allergens in the production process and ensure the safety and stability of food quality in the production process. The flow chart of future emergency food research and development strategy is shown in Figure 1.

Figure 1 Future Emergency Food R&D and Development Strategy Process

conclusion

In recent years, emergencies have occurred frequently in China, and the demand for emergency food has been rising continuously. Especially after the COVID-19 epidemic, China residents’ awareness of food nutrition and safety has been continuously enhanced, and food is required to have certain functionality while meeting basic energy. Therefore, one of the first tasks in the post-epidemic period is to accelerate the research on emergency food.

For the development of emergency food in China, there are many problems in the process of modern rescue, such as insufficient nutrition supply of emergency food, imperfect functional food and difficulty in accurate distribution. Based on this actual situation, the design and development of rescue food with complete nutritional functions, convenient eating and convenient storage and transportation, and the realization of industrial production can not only meet the national emergency relief needs, but also fill the food shortage of emergency relief materials.

By analyzing the development gap of emergency food at home and abroad and thinking about the future development trend of food, this paper puts forward three research and development directions of emergency food, and produces a series of safe, fresh, nutritious and stable emergency food through intelligent supply chain and accurate and efficient detection technology, so as to make it have core competitiveness and greater development space in the market, and gradually open and improve the emergency food market in China.

　　On Wednesday, Eastern Time, US chip stocks experienced a one-day rebound tour, which weakened in an all-round way overnight, and the market was also dragged down. The three major indexes were mixed. In addition, after the release of heavy inflation data, the market also lacked catalysts, and the overall performance was relatively dull.

　　At the close, the Dow Jones index rose 0.10% to 39,043.32 points; The S&P 500 index fell 0.19% to 5,165.31 points; The Nasdaq index fell 0.54% to 16,177.77 points.

　　The yield of US bonds has rebounded, with the benchmark 10-year US bond yield closing at 4.1879% and the 2-year US bond yield, which is most sensitive to the Fed’s policy interest rate, closing at 4.6324%.

　　It may take some time for the market to digest the inflation data, because the last interest rate meeting in the first quarter will be held next week. At this meeting, the bitmap and economic outlook will be announced, when investors will have a clearer expectation for the prospect of interest rate cuts. Before that, if there is no heavy news, US stocks may be more inclined to defensive trading strategies.

　　Some analysts said that although the latest CPI data is a relief, people are still cautious about the basic data. In the short term, the macro narrative around the Fed will be the primary and central issue.

　　Let’s pay attention to the progress of the US presidential election again. According to Xinhua News Agency, according to calculations and reports from many mainstream media in the United States, former President Trump locked in the Republican presidential nomination for the 2024 US presidential election on the 12 th. That is to say, if there is no accident, Biden and Trump will fight for the second time in the presidential election, but the market has not obviously responded to this at present, and the policies pursued by the two are worthy of attention.

　　In terms of enterprises and industries, it is not as dull as the broader market. Tesla, in particular, has been under the headwind so far this year, and was once again slashed by two investment banks overnight. UBS maintained Tesla’s neutral rating and lowered its target price from $250 to $165. Wells Fargo lowered Tesla’s target price from $200 to $120. Tesla fell more than 4% overnight to $169.5, and there was still 30% room for decline from Wells Fargo’s target price.

　　Colin Langan, an analyst at Wells Fargo, reported that the growth of the electric car manufacturer in the core market has slowed down. He downgraded Tesla’s rating to the equivalent of selling. It is expected that Tesla’s sales will be flat this year and will decline in 2025. Langan writes that Elon Musk’s company is a "growth company without growth". He pointed out that in the second half of 2023, sales only increased by 3% compared with the first half, while prices fell by 5%. Analysts have become more and more cautious about Tesla, and the bullish rating ratio has dropped to the lowest since April 2021.

　　In the future, see how Musk will fight back.

　　In terms of AI, Figure, a robot startup company blessed by Amazon and NVIDIA, has released its first robot demo blessed by OpenAI. Although only a neural network is used, it can be used to hand apples to humans, put black plastic bags into frames, and put cups and plates on the drain rack in order to obey human orders.

Speaking this sentence, Xiong Wenzheng, deputy director of the office of Changsha Tongcheng Holding Co., Ltd., was sitting in the office on the seventh floor of Golden Family. He had been working and living in Dong Tang business circle for more than 30 years. At the peak of Dong Tang Department Store, Xiong Wen, who was in his early twenties, was passionate and splashed ink, writing a magnificent chapter "Four acres of brilliant land" for Dong Tang Department Store. (Originally published in Changsha People’s Congress Magazine)

Today, standing on the 7th floor of Golden Family, looking out from the window, Dong Tang business circle in late autumn of 2020 is still lively. The construction of the subway station has been basically completed, and the streets are crowded with people.

For an old man like Xiong Wen in Changsha, such a scene made him feel a little sentimental.

Dong Tang in the 1980s.

In the south city of Changsha, the Dong Tang business circle once flourished, bearing the memory of old Changsha. There used to be a reputation of "selling yellow mud can make money", and it also suffered from the embarrassment of declining popularity. "The road to the revival of Dong Tang business circle" has always been a hot topic.

What was the prosperity of Dong Tang business circle? Why did it once decline? Where is the road to its revival?

The east wind came overnight? Here once dominated the evolution theory of Changsha’s business.

In the memory of the old Changsha people, anyone who dabbles in the local business community will never forget the lively and beautiful era of "Fighting with Five Tigers in Changsha" …

In January, 1983, Dong Tang Department Store (the original site of Cash Family) located in the northwest corner of Dong Tang was completed and opened. In the following years, the nearby clothing trading building, cloth market and Changsha Workers’ Cultural Palace were completed and put into operation. Around this small area of Dong Tang, the integration of various formats has gradually formed. At that time, it really started an era of Changsha commerce, and the Dong Tang business circle also took shape.

The completed Dong Tang Department Store.

The salesperson of Dong Tang department store is picking up the goods for the customers.

There is a constant flow of traffic and people coming and going near Dong Tang Department Store.

In the commercial map of Changsha at that time, with the Dong Tang business circle raising the war flag in the southeast, Dong Tang Department Store, Shaoshan Road Department Store, Zhongshan Road Department Store, Xiaoyuan Department Store and Friendship Store at that time, ignited a commercial competition war of "five tigers fighting in Changsha".

Xiaoxiang Cinema at that time

Competition has promoted the development of business, but also brought an opportunity to take off.

Around 1995, a number of Changsha local time-honored brands, such as Friendship Mall, Fire Palace and Xinhua Building, successively settled in Dong Tang, which led to the completion of a large-scale upgrade of the business circle. The Dong Tang business circle and the Wuyi business circle echoed each other from a distance and became the main focus of Changsha’s business in the south of the city.

At this point, the Dong Tang business circle has entered a stage of rapid development-

17 years ago, Tongcheng Electric built a flagship store in Dong Tang, which is known as "the first store in Central China".

In 2004, Tongcheng Electric entered Dong Tang as a flagship store, which is also the largest store of Tongcheng Electric in the province.

In 2005, Dong Tang Metropolis Commercial Street opened, which is the first underground commercial street in Changsha with a total length of 624 meters.

In 2012, Friendship Mall achieved a turnover of 1.3 billion yuan with a business area of 27,000 square meters on the upper and lower floors, ranking first in Hunan’s commerce and trade industry.

With the vigorous development of commerce, in this small area of Dong Tang at that time, the Yuhua District Government embodied strategic and forward-looking policy support and planning guidance, and formed a teaching and training industry around the educational resources of Dong Tang business circle; The cultural tourism industry formed around Xiaoying Group has gradually taken shape. These characteristic industries once formed the basic market of Dong Tang business circle outside commerce. This all-round industrial layout once led the evolution and development of Changsha’s commerce …

Internet e-commerce impacts consumers’ shopping habits are quietly changing.

If you go back to more than ten years ago, if you come to Dong Tang at that time, you will see that the popularity is no less than the lively scene of Wuyi Square or Taiping Street today-

Dong Tang Department Store and Friendship Shopping Mall are separated on both sides of the square, where most famous brands that can be bought in Changsha at that time are gathered. And across the intersection, in the bustling metropolis commercial street and Dong Tang clothing exchange building, you can find all kinds of cheap and fashionable clothing accessories.

As an old-fashioned commercial street, the metropolitan commercial street ushered in its heyday after the Millennium.

According to the memories of merchants who used to do business here, people crowded around Dong Tang every day, and many Changsha citizens even bought clothes and swept the goods with big sacks. "Business will not be interrupted from morning till night. At that time, merchants had to go to the clothing building early every morning to grab goods, and there would be no best-selling styles if they were late. In the metropolitan commercial street and Dong Tang clothing exchange building, all fashionable clothes could be found at that time. Many young people go to Dong Tang to go shopping, eat, buy clothes or trinkets after work or after class … "

The once bustling commercial street in Dong Tang metropolis.

At that time, the Dong Tang business circle has become a rival to the May Day business circle. When it comes to Dong Tang business circle, if the admission of Pinghetang, Dong Tang Department Store and other groups is just a prelude, then the opening of Dong Tang Clothing Exchange Building and Metropolitan Commercial Street is the booster for Dong Tang business circle to reach its peak.

However, no one ever thought that after 2012, the decline of Dong Tang business circle came quietly …

With the popularity of online e-commerce shopping and the upgrading of people’s consumption level and business model, the business of underground commercial streets began to decline. Many shops are promoting sales with various discounts, but few people still patronize them, and their business is still very deserted. Some shops have already posted advertisements for subletting.

"At that time, e-commerce developed rapidly, and many popular styles of clothes were also available online, and the price was cheaper. The popularity here suddenly cooled down. Moreover, compared with other emerging business districts with rapid development and complete facilities in Changsha, the shopping environment of underground commercial streets here is not good. The business in other parts of Changsha is developing, but here in Dong Tang is stagnant … "Zhao Xu, the floor supervisor of Friendship Mall, has lived in Dong Tang for 26 years, and he can’t help but be deeply touched when he sees that the business circle in Dong Tang has grown from bustling to deserted.

Wang Yigao, deputy director, researcher and professor of Hunan Institute of Economic Geography, has lived in Dongtang business circle for more than 20 years. He analyzed the dilemma faced by Dong Tang business circle from a more professional perspective. "Internet e-commerce has a greater impact on physical stores, which has changed people’s consumption patterns and habits to some extent; In addition, shops in Dong Tang business district are generally expensive in rent and lack of functional supporting facilities. The times are developing, and citizens’ demand for shopping conditions and consumption environment is constantly improving. As an old business district, Dong Tang basically has no large underground parking lots, no boulevards for leisure walks, and no squares for fun … "

Professor Wang Yigao also said: Compared with the "Fire Palace" and "Taiping Old Street" with a strong sense of history in the May 1 business district, the Dong Tang business district lacks historical precipitation, which affects the development of diversified business patterns; For a long time, the architectural layout of Dong Tang was also lack of planning, and office buildings, factories, institutions, research institutions and commercial complexes were blindly confused, resulting in a chaotic pattern and mixed roads, which did not form a three-dimensional traffic pattern. All along, the businesses in Dong Tang have been fragmented and have not formed a unified alliance. Coupled with the subway construction in Dong Tang in recent years, various factors have caused the rapid decline of Dong Tang business circle in recent years.

Dong Tang Business Circle, Friendship Shopping Mall, Metropolis Commercial Street … These nouns have accompanied a generation of Changsha people through beautiful memories of youth. However, with the development of the times, the "old business circle" has become a lonely term.

When you make a comeback! Night economy and the "revival" assisted by subway lines

Dong Tang business district is bustling with night.

On June 28th, 2020, Changsha Metro Line 3 along Dong Tang was opened.

In the eyes of some insiders, this is a new opportunity and new kinetic energy for the revival of Dong Tang business circle. However, is it enough to solve the grand proposition of "revival of the old business district" just by a subway line?

Wang Lin, a professor at Central South University, once said in an interview with the media that all businesses in the Dong Tang business circle are fragmented, which has led to the current decline. To revitalize the business circle, we must first conform to the natural development of the economy, and then the guidance of the government.

Some people in the industry also pointed out that if the opening of the subway brings good times to the revival of Dong Tang business circle and Dong Tang’s own location is favorable, then it is necessary to find the "harmony between people" in the revival of business circle, that is, to face the shortcomings of business circle directly, and enterprises and the government should come up with some effective ways to break the situation.

Dong Tang Metropolitan Commercial Street

On July 15th, 2020, Liu Suyue, deputy secretary of Yuhua District Committee and district head, led a team to investigate the surrounding environment of Dong Tang business circle, and visited Golden Family, Xiaoxiang Film Group and other enterprises, and then organized some business representatives from Dong Tang business circle to hold a symposium on the theme of "How to revive Dong Tang business circle".

At the symposium, representatives of Xiaoxiang Film Group, Fire Palace, Golden Family, Pinghetang, SINOMACH International, Tongcheng Electric Appliances, Xinhua Building and other enterprises launched a heated discussion around the "revival" of Dong Tang business circle.

The person in charge of Hunan Xiaoxiang Cultural Industry Investment Co., Ltd. proposed that the Dong Tang business circle is in urgent need of transformation and upgrading! With the arrival of the economic development tide in experience tourism, Xiaoxiang Film Group wants to build an experience city of film and television culture, attract more people to know about film and television culture, and turn it into a "meeting room of film and television culture" in Hunan, so as to drain the business circle and provide a new engine for its development, thus driving the development of the whole business circle.

The relevant person in charge of Friendship Mall said that during the epidemic, the mall launched a series of live online activities, which was a great success. The sales performance in May and June increased by about 3% compared with last year. Through practice, it is found that the influence of live broadcast sales is very strong, so the next step will continue to deepen online channels, and at the same time, fashion brands that young people love will be introduced one after another.

Think about how to transform and upgrade, how to attract consumers, especially young consumers, and how to strengthen linkage, dislocation management and information sharing between businesses?

This is the thinking put forward by Liu Suyue, deputy secretary of Yuhua District Committee and district head, to Dong Tang business circle at this meeting.

Today’s Dong Tang business circle

At the meeting, the specific arrangements made by the Yuhua District Government for the development of Dong Tang business district are also ready to come out: good guidance, good planning, scientific positioning, focusing on Dong Tang’s characteristics and advantages; Plan more activities related to consumption festival according to time nodes, and guide businesses to strengthen linkage consumption and related consumption; It is necessary to take the lead in setting up business alliance institutions and strengthen the linkage between enterprises and governments and between enterprises; With the help of Tik Tok and other new media, strengthen the publicity of Dong Tang business circle; It is necessary to improve the basic supporting facilities of the business circle, strengthen the rectification of advertising spaces, improve the lighting at night, and solve the problem of parking difficulties through the sharing of parking spaces, so as to create a good market environment for the business circle.

There are indications that Dong Tang, the "old business district", seems to have signs of oriental wind. With the comprehensive promotion of Changsha’s "Night Star City" consumption festival and the launch of Yuhua District’s "Slow Nightlife, Meet You" activity, the Dong Tang business circle reappeared after the epidemic.

Dong Tang business circle in the future, just like a young man gearing up, is coming back with a new attitude, which is expected to reproduce the "paradise for shopping and leisure" in Changsha people’s mind.

According to the Chinese Embassy in Britain, on March 22, 2021, the Chargé d ‘affaires of the Embassy in Britain, Yang Xiaoguang, successively received an exclusive interview with British Sky News, TV 4 and BBC, explaining China’s principled position on the sanctions imposed by the European Union and Britain on relevant institutions and personnel in China due to Xinjiang-related issues, and refuting wrong remarks. Sky News and TV 4 broadcast live reports, and BBC broadcast some interviews in the news program that night.

In response to the British Foreign Development Secretary’s announcement that Britain will impose sanctions on China officials and entities,Agent Yang said that Xinjiang affairs are entirely China’s internal affairs. Based on lies and false information, the British side imposed unilateral sanctions on individuals and entities in China on the pretext of human rights issues, ignored the facts, turned black and white, grossly interfered in China’s internal affairs, blatantly violated international law and the basic norms of international relations, and seriously damaged Sino-British relations. China expresses strong dissatisfaction and resolute opposition to this, and reserves the right to take corresponding countermeasures to safeguard China’s interests and dignity.

In response to China’s question about whether it was surprised by the British government’s decision,Deputy Yang said that China was not surprised, but deeply disappointed, and resolutely opposed this wrong decision. Sanctions will not only have no effect on China, but will make the people of China more united. The basic reaction I have heard is that Chinese officials who have been sanctioned are deeply honored to be able to defend national interests.

In response to the question whether China will take countermeasures against Britain,Agent Yang said that China does not take the initiative to provoke confrontation and attack others, but it will not be trampled upon by others and will resolutely fight back. China will not succumb to external pressure, and we should not underestimate our determination and confidence in safeguarding national sovereignty, security and development interests. China is carefully studying the British statement and will make an appropriate response in due course. China urges the British side to change its course in time, withdraw relevant wrong decisions, avoid damage to bilateral relations, and take effective measures to bring Sino-British relations back to the right track.

In response to the question that Xinjiang Education and Training Center is equivalent to a "concentration camp", China has carried out "genocide" and "forced labor" on Uighurs, forced sterilization on Uighur women and separated Uighur children from their parents, Agent Yang pointed out that China has repeatedly stated that there is no so-called "genocide", "forced labor" and "mass sterilization" in Xinjiang. These accusations against Xinjiang are groundless and "century lies". The so-called evidence hyped by the British media is completely malicious lies and false information, which has no credibility at all. The relevant pictures and videos are fabricated or taken out of context.

Agent Yang said that China’s establishment of the education and training center is a preventive anti-terrorism measure to educate and save those who are infected by extreme thoughts, involved in terrorism activities or seriously influenced by extreme thoughts and prevent them from going to terrorism. Facts have proved that this measure has effectively protected the life safety of people of all ethnic groups in Xinjiang, including Uighur compatriots, and also guaranteed the right of the students concerned to reunite with their families according to law. Students study the national common language, legal knowledge and vocational skills education and training in the teaching and training center. After graduation, they generally find suitable jobs and their living standards are improved.

Agent Yang said that cotton production in Xinjiang has been highly mechanized, and there is no need for a lot of manpower. Moreover, there are few job opportunities, high pay and fierce competition. Where is the need for forced labor?

Agent Yang said that the family planning policy is still the basic national policy of China, which is implemented nationwide, but it is more relaxed for ethnic minorities, including Uighurs. The accusations you mentioned are sheer nonsense.

Agent Yang pointed out that the pictures repeatedly broadcast by British TV programs are scenes of centralized transfer of prisoners in Xinjiang detention center, which has nothing to do with the teaching and training center. These prisoners are dangerous people suspected of breaking the law, so it is absolutely necessary to take security measures for them, and there is no abuse problem.

Agent Yang stressed that facts have repeatedly proved that the accusations against China are unfounded. In 2019, Xinjiang received more than 200 million Chinese and foreign tourists. If there are a lot of "torture" or "misconduct" in the local area, why is there no more evidence? In fact, China’s Xinjiang policy has been widely understood and supported internationally. At the 46th session of the United Nations Human Rights Council, 64 countries, including Arab countries, made a joint speech in support of China’s Xinjiang policy. We welcome more tourists from all over the world to visit Xinjiang after the COVID-19 epidemic, and believe that they can make correct judgments through what they have seen with their own eyes. What China has done in Xinjiang is frank and aboveboard, which can stand the test of history.

In response to a question about the nature of the Public Security Bureau of Xinjiang Production and Construction Corps, agent Yang said that the primary responsibility of the public security organs of Xinjiang Production and Construction Corps is to protect the lives and property safety and legitimate rights and interests of people of all ethnic groups, including Uighurs. Over the years, the public security organs of the Corps have cracked down on serious crimes such as terrorism according to law, which has been sincerely supported and generally supported by the local people of all ethnic groups.

In response to a question from the former US Secretary of State that China had put Uighurs in "concentration camps" and instilled communist party’s ideas and carried out "genocide", Agent Yang said that there was no "genocide" in Xinjiang. A century or two ago, the United States massacred Indians, and what they did was called "genocide."

On the question of whether China allows the United Nations High Commissioner for Human Rights to visit Xinjiang and whether foreign journalists are allowed to visit Xinjiang freely, Agent Yang said that China welcomes the United Nations High Commissioner for Human Rights to visit China and Xinjiang, and has kept close communication with the United Nations. The door of Xinjiang is open. We welcome people who are unbiased and really want to know about the development of Xinjiang to visit Xinjiang, but we firmly oppose any condescending presumption of guilt. According to the relevant regulations of China, foreign journalists can go to Xinjiang to report on the premise of abiding by the laws of China and fulfilling relevant procedures.

In response to a question about a British parliamentarian claiming that he was "harassed on the Internet by diplomats of the China Embassy", Agent Yang said that some British parliamentarians have repeatedly made false statements about Xinjiang on social media, and China diplomats have the right to clarify the truth and set the record straight. Members can make false statements, so we have no right to state the facts? Why do you say "harassment"?

On the question of whether "one country, two systems" in Hong Kong has become "one country, one system" and whether the Legislative Council of Hong Kong will become a "rubber stamp", Mr. Yang said that the China government has always fully and accurately implemented the policy of "one country, two systems", but "one country" is the prerequisite. After the storm of amending regulations, "one country" has been seriously impacted, and it is necessary to strengthen "one country" in order to better guarantee "two systems". What China has done is to ensure that "one country, two systems" is stable and far-reaching, and to ensure that the interests of the overwhelming majority of Hong Kong people are safeguarded. Members of the Legislative Council of Hong Kong come from all walks of life and are widely representative. In the future, there will still be many voices in the Hong Kong Legislative Council. On the premise of safeguarding national sovereignty and territorial integrity, members’ right to express their opinions is guaranteed.

　　Finishing | Wu Xue

　　I am a courier and a "organizer".

　　At 5: 00 a.m. on February 13th, I woke up in a bunk bed in the express warehouse outside the Second Ring Road in Wuhan. This warehouse was a little special, and it happened to be built at the sewer crossing. It was damp and cold. I picked up the thermometer and took my temperature, which was no more than 36 degrees. I looked at my mobile phone calendar before going out. It turns out that I haven’t been home for 22 days.

　　Yong Wang has been living in the company warehouse these days.

　　I’m Yong Wang, born and raised in Wuhan, and I’m an ordinary post-80s courier brother. From morning till night, I work hard day after day to deliver, pack, deliver and move goods, which is enough for a family of three. I throw myself into the battle every day when I wake up, like a "top" wound up. At the beginning of February, reporters came to me one after another to follow up the interview. I never thought that I would become a news figure in this epidemic.

　　Seeing the nurse home, she cried all the way

　　Things should start from the New Year’s Eve. Because of the epidemic, the courier company had a holiday. In the evening, I closed the warehouse and returned home to have a reunion dinner with my relatives. At 10 o’clock in the evening, when I was going to coax my daughter to rest, I suddenly brushed into a circle of friends from a nurse in Wuhan Jinyintan Hospital. The other party wrote: "Help, we are restricted here. There are no buses and subways, and we can’t go home. It takes four hours to walk back." The demand was released at 6 o’clock, and no one took the order.

　　Yong Wang in protective clothing.

　　"Go or not" at that time, I was struggling, but I really wanted to do it. I didn’t dare to tell my family that I spent an hour alone in psychological struggle. Finally made up my mind to "go". My wife is a psychologically fragile person and has never experienced any major events; Parents are getting old again, so we can’t let them worry. So, I decided to take this matter alone — — Keep it from them with white lies.

　　The first question is how to get out. The nurse who issued the bill was on the night shift at six o’clock the next morning. I told my wife that there was a temporary need for the staff on duty at the outlet, and I was sent to be on duty, so I managed to hide it smoothly. At that time, I didn’t have any protective equipment in my hand, so I went to the supermarket to buy two N95 masks and arrived at Jinyintan Hospital on time at six o’clock. The nurse paused when she saw me. "I didn’t expect anyone to take this bill." Then, she got on the bus, said nothing all the way, sobbed silently until she got off the bus.

　　On the first day, I sent more than a dozen medical staff to and from Jinyintan Hospital. At the end of the day, my legs kept shaking. To tell you the truth, I’m scared in my heart. What if I get infected? I began to retreat and persuade myself, "Forget it." But when I saw a nurse sending a bill at night, the destination was dozens of kilometers away from the hospital, and no one answered it. Suddenly changed his mind.

　　I made up a second "lie" and told my wife that I was in contact with a suspected patient and was afraid of being infected. I could only sleep in the express warehouse for 7 days and go home without any problem. At first, my wife didn’t listen to my explanation and cried bitterly. Later, when her mood was stable, she agreed. And slowly, with more contact with medical staff, I began to understand why they would rather walk than go home when they take a break.

　　In fact, in the week before the national medical rescue team came, all the medical staff in Jinyintan fought all night, 10% of them could sleep in bed, and the rest were armchairs; The groans of patients and the 24-hour call on walkie-talkies are unbearable for anyone, let alone have a good rest. Therefore, even if they walk for four hours on the road, it is a short rest for them.

　　The medical staff took a short nap in the armchair.

　　The medical staff took a short nap in the armchair.

　　On the fourth day of the Lunar New Year, more and more medical teams supported Wuhan, as if giving them a "shot in the arm". That day, I was supposed to pick up a doctor to go to work, when I suddenly received a phone call from her: "Master, you don’t have to pick me up. I can take a day off today." At that time, I was very happy. I built a medical service group and more and more people entered. I began to find that even if I tried my best, I could only meet the demand of 300 kilometers.

　　Recruit volunteers to transport medical staff together.

　　So, I began to post news in my circle of friends to recruit volunteers, insisting that I must live alone and wear protective equipment. If the answer is no, I will refuse them. Next, twenty or thirty people followed me in turn, and we broke three cars in the middle. Later, six cars basically met the demand. But it is still not a long-term solution, and some people suggest that we can find resources.

　　We first contacted mobike, and their delivery efficiency was very fast. All points in hospitals and hotels and vehicle personnel were in place in one day, which solved the travel demand of about 2 kilometers; Then docking Didi, because the process of big companies is cumbersome and takes a long time, and it takes a week to get it done. In order to meet the travel needs of medical staff in Jinyintan Hospital outside the Third Ring Road, Didi directly changed the number of kilometers received from less than 3.5 kilometers to less than 15 kilometers.

　　Green orange bicycles set up service points on Panlong Bridge.

　　The docking of green orange bicycles was also completed within three days, and 400 bicycles were put into use. From the aspects of operation and maintenance, cost and delivery, there was a special team management, which completely solved the travel problem at once. In those days, every night, I had to take an hour to play video with my family. I was afraid to disclose the recruitment and help information to my family in my circle of friends, but with the increase of the number of trips abroad, the task became more and more busy, and this matter could no longer be concealed. My wife was very flustered when she knew it. I did ideological work and finally expressed my support and understanding.

　　It’s just that my two-year-old daughter is very attached to me. At night, she clamors to sleep with her father. If she can’t find it, she just sits in the corner and cries. On the Lantern Festival, I watched the video of her kissing and kissing on my photo, and I felt particularly guilty and missed my family.

　　But I know that I can’t stop. The medical team that rushed to Wuhan is our "lifesaver". The government has arranged for them to have food and a place to live, but the details may not be taken care of. We can check and fill the gaps and try our best not to mistreat them.

　　Wang Yong’s family

　　Yong Wang’s daughter saw her father’s photo and kissed her.

　　Want to eat rice, we settled a restaurant.

　　At the beginning, we raised 22,000 yuan to provide instant noodles and water for night shift medical care. Later, a nurse sent a circle of friends saying that she really wanted to eat rice. After seeing it, I was so sad that I made up my mind to let them eat white rice the next day. Soon, a restaurant owner docked, 16 yuan a copy, more than 100 copies a day. The next day, the owner of a restaurant in Wuhan came to me and said that 1500 lunches a day could be provided free of charge to Jinyintan Hospital, Xinhua Hospital and Union Medical College Hospital respectively.

　　The dining problem has been solved, but I have found another new situation: the load of docking restaurants is too great and the production capacity has reached its peak. I began to imagine whether we could have a special restaurant for meals under the condition that many existing resources are tilted. I soon began to implement it. I went to more than 20 restaurants a day to talk about cooperation, and asked one by one if we could use the venue and staff for free or at a low price. Soon, the owner of Jinjiushan Restaurant agreed with our goal and hit it off.

　　Jinjiaoshan restaurant began to serve meals free of charge.

　　On February 3rd, Jinjiaoshan Restaurant began to provide meals, with two meats and one vegetarian, which quickly satisfied the dining problem of Jinyintan Hospital. The rest of the production is supplied to Didi drivers for 240 copies every day. Since others are here to help us, we should not graft the risks to others. Unfortunately, on February 7, the local food safety department in Wuhan closed the restaurant and demanded to stop business.

　　The reason is that during the critical period of the epidemic, only a few designated units are allowed to produce meals, and this qualification cannot be applied for at present. After a day of unsuccessful communication, in desperation, we contacted several designated catering units and found that the other party said that the cost of a box lunch was 40 yuan, and the funds we raised could not afford it at all.

　　I was very frustrated at that time, but then things began to turn around. Today Convenience Store, a local enterprise in Wuhan, has solved the dining problem: providing all the support teams in Jinyintan Hospital with meals every day, and supporting Didi owners with 300 free lunches every day. I finally breathed a sigh of relief that day.

　　Materials provided by Today convenience store to medical staff

　　Free box lunch provided by Today convenience store

　　I don’t have any resources, but I am ready to respond.

　　I am a person without any resources, but along the way, I am especially grateful to the volunteers and big companies for their help. Everyone is working hard for this matter. I am just a person who organizes the bureau. Travel, dining — — Each group has a bureau, and I will give it to one person to manage it, and then I will free my hands to do other things. Because I have much contact with medical staff on weekdays, I know their current situation best, and life support is also essential.

　　For example, if the glasses are broken and the screen of the mobile phone is broken, you need to buy slippers, nail clippers, chargers and even autumn clothes and trousers, and shout through the solitaire in the group, and someone will soon purchase them to help them get it. I remember one time, two doctors of Shanghai Medical Team celebrated their birthdays. We bought them cakes and had an unforgettable birthday. Another time, because the air conditioner in the hospital couldn’t be turned on, the medical care lacked sleeveless down jackets for warmth. We spent 100,000 yuan to buy all the down jackets of Shangchao, and ordered 1,000 pieces of Uniqlo in Guangzhou.

　　Master Gan, a volunteer hairdresser, has been on duty for 5 times and received rave reviews.

　　Yong Wang docking service in the group Anhui assistance Wuhan intensive care unit.

　　Yong Wang organized volunteers to buy birthday cakes for the Shanghai medical team.

　　One thing that impressed me the most was that the medical staff needed a batch of protective shoe covers, and the whole city of Wuhan was out of stock. Later, a merchant was found on Taobao, but in gedian, Ezhou, 55 kilometers away from Wuhan, because the merchant was also a confirmed patient in COVID-19, the express delivery could not be made. I drove to get it overnight and brought back 2000 pairs.

　　I keep doing things and solving problems every day. I don’t know when I will stop, but as long as the medical staff calls me, I am always there. Up to now, we have docked a total of 1,000 medical staff, and then we will dock 3,000 medical teams that rushed to Wuhan.

　　On February 2, Yong Wang released a circle of friends and wrote: I have lived for so many days, but the nurse’s concern made me cry.

　　People can’t touch such a big thing in their lives. No matter what they do, they do their best and have no regrets. Actually, when I think about it, my original intention to do this is very simple. One day, picking up and dropping off a medical staff can save four hours, and picking up and dropping off 100 people is 400 hours, 400 hours. I earn money no matter how many people the medical staff can save.

　　On the evening of February 13th, my mother’s friend saw my video and told my mother by phone, expressing great support to me. In the eyes of relatives and friends, I have never been a worry-free child since I was a child. Until now, my parents are still worrying about me, helping me take care of my children and subsidizing my family. Fortunately, what I have done this time has not humiliated you.
