Special Action Plan for Cigarette Counterfeiting in Guangdong Province this winter and next spring

　　In order to further crack down on the illegal and criminal activities of manufacturing and selling fake and shoddy cigarettes, purify the cigarette market environment, safeguard the legitimate rights and interests of enterprises and consumers, and standardize the market economic order, this special action plan is formulated according to the requirements of the "Guangdong Province Anti-counterfeiting Work Plan in 2003".

　　-guiding ideology

　　Guided by Deng Xiaoping Theory and Theory of Three Represents, conscientiously implement the spirit of the 16th CPC Central Committee and the Third Plenary Session of the 16th CPC Central Committee and the spirit of General Secretary Hu Jintao’s important speech on inspecting Guangdong, adhere to the principle of "combining crackdown with prevention, treating both the symptoms and root causes, and paying equal attention to rectification and standardization", and follow the unified arrangements of the State Council, the provincial party committee and government, and the requirements of the State Tobacco Monopoly Bureau, the Ministry of Public Security and other relevant departments. According to People’s Republic of China (PRC) Criminal Law, People’s Republic of China (PRC) Criminal Procedure Law, People’s Republic of China (PRC) Tobacco Monopoly Law, People’s Republic of China (PRC) Tobacco Monopoly Law Implementation Regulations and other relevant laws and regulations, all relevant departments should, under the leadership of the local government, carry out their duties, cooperate closely and cooperate with each other, severely crack down on illegal and criminal activities of manufacturing and selling fake and shoddy cigarettes, severely punish criminals, and further consolidate and expand the achievements of cigarette counterfeiting and rectifying and standardizing the market economic order in our province.

　　Second, the work objectives

　　(a) the establishment of "the local government is responsible for the guidance and coordination of the anti-counterfeiting office, all parties work together, and the masses actively participate" in the leading mechanism and joint case handling mechanism of cigarette counterfeiting. The provincial anti-counterfeiting office is responsible for the organization, coordination and inspection of cigarette anti-counterfeiting work; Tobacco, industry and commerce, quality supervision and other departments are responsible for investigating and dealing with illegal and criminal activities of manufacturing and selling fake and shoddy cigarettes according to law; The public security department is responsible for investigating suspected criminal cases such as manufacturing and selling fake and shoddy cigarettes and illegally assembling and reselling cigarette machines; The supervision department is responsible for investigating the responsibility of public officials who violate the law and discipline, and supervising the implementation of the responsibility system for counterfeiting.

　　(two) combined with the "solid foundation" work, pay close attention to the implementation of cigarette counterfeiting responsibility system. Governments at all levels should conscientiously implement the responsibility system for counterfeiting, especially the implementation of the responsibility system for counterfeiting cigarettes at village and town levels.

　　(3) Effectively control the momentum of large-scale, mass and group-based illegal and criminal activities of manufacturing and selling fake and shoddy cigarettes in key areas of our province, so that the incidence rate of major cases of manufacturing and selling fake and shoddy cigarettes has dropped significantly.

　　(four) check the network, dig gangs, end dens, catch the principal offenders, and thoroughly investigate and deal with a number of major cases involving a wide range, serious circumstances and bad nature; Dig deep into the source of counterfeiting in the production of hoods, tobacco and printed trademarks and their behind-the-scenes planning, organization and funders; Severely punish a number of ringleaders and their "protective umbrellas" who commit crimes of manufacturing and selling fake and shoddy cigarettes according to law.

　　(five) the provincial tobacco monopoly bureau should strengthen the clean-up and rectification of the cigarette market, and cooperate with the industrial and commercial departments to do a good job in daily management.

　　Third, key remediation areas

　　This winter and next spring, the key rectification areas of cigarette special anti-counterfeiting action are: Guangzhou, Shantou, Jieyang, Chaozhou and Maoming; The key counties (cities, districts) for rectification are: Chaoyang District and Chaonan District of Shantou City, Raoping County and Chaoan County of Chaozhou City, Jiexi County, Huilai County and Puning City of Jieyang City, Huidong County of Huizhou City, Baiyun District of Guangzhou City, Zengcheng City and Dianbai County of Maoming City. Other parts of the province should also intensify the crackdown and prevention to ensure that the illegal and criminal activities of manufacturing and selling fake and shoddy cigarettes do not spread or spread.

　　Fourth, the time schedule

　　The special campaign lasted from October 2003 to March 2004 and was conducted in three stages:

　　The first stage (preparatory stage): from the end of October to the end of November, 2003, make a thorough investigation, grasp the basic situation of illegal and criminal activities of manufacturing and selling fake and shoddy cigarettes and their leaders and backbones within their jurisdiction, and formulate specific action plans.

　　The second stage (strike stage): from late November 2003 to the end of January 2004, a large-scale inventory operation was jointly organized to crack down on illegal and criminal activities of manufacturing and selling fake and shoddy cigarettes and severely punish criminals and their "protective umbrellas". During the New Year’s Day and the Spring Festival, governments at all levels and relevant departments should actively organize forces and cooperate with each other to set off a climax of cracking down on illegal and criminal activities of manufacturing and selling fake and shoddy cigarettes.

　　The third stage (summary and commendation stage): from the first ten days of February to the end of March, 2004, the provincial anti-counterfeiting office will take the lead in inspecting and supervising the special anti-counterfeiting operations in winter and spring in various places, and commend and reward the units and individuals that have made outstanding performance during the special operations.

　　V. Organizational leadership

　　In order to strengthen the leadership of the special campaign against cigarette counterfeiting this winter and next spring, and ensure the effectiveness of all the work, the provincial government decided to set up a special action supervision group to be responsible for the coordination and command of the special action. The steering group is led by the provincial anti-counterfeiting office, and its members are composed of relevant personnel from the anti-counterfeiting office, public security, industry and commerce, quality supervision, tobacco, discipline inspection and supervision departments.

　　VI. Job Requirements

　　(A) to raise awareness and strengthen leadership

　　The illegal and criminal activities of manufacturing and selling fake and shoddy cigarettes have destroyed the normal social and economic order, damaged the honest, trustworthy, fair and competitive market environment, endangered the physical and mental health of the broad masses of people, caused huge economic losses to the country and enterprises, and damaged the image of our province. Governments at all levels and relevant departments should fully understand that cracking down on the illegal and criminal activities of manufacturing and selling fake and shoddy cigarettes is an important measure to rectify and standardize the market economic order and improve the socialist market economic system from the height of practicing Theory of Three Represents; Fully understand the particularity, long-term and arduousness of cigarette counterfeiting, overcome slack thinking and war-weariness and make unremitting efforts. Governments at all levels should adhere to the principle of "keeping the soil responsible", and take cigarette counterfeiting as an important part of counterfeiting work. The leaders in charge of the government should personally grasp it, organize it carefully and make careful arrangements. All localities should refer to the practice of the province, set up corresponding institutions, and effectively strengthen the organization and leadership of special actions.

　　(2) Close cooperation and coordinated operations.

　　Cigarette counterfeiting involves a wide range, and all relevant functional departments should carry out their duties, coordinate and cooperate, and make key breakthroughs to ensure the effectiveness of all work. Tobacco, industry and commerce, quality supervision and other administrative law enforcement departments should intensify the investigation and punishment, and the suspected criminal cases should be promptly transferred to the public security organs for handling in accordance with the Provisions of the State Council on the Transfer of Suspected Criminal Cases by Administrative Law Enforcement Organs, and punishment should not be substituted for punishment. Public security organs should promptly carry out investigations, collect criminal evidence and arrest criminal suspects. Public security and judicial departments at all levels should actively study issues such as fact finding, evidence confirmation and application of laws according to the new situation and new characteristics of cigarette counterfeiting and selling activities, and punish illegal and criminal cases with serious circumstances and bad influence quickly and severely according to law in order to deter criminals. Public security organs in Guangzhou, Chaoyang, Chaonan, Puning and other places should intensify their efforts to pursue suspects who are at large in manufacturing and selling counterfeit and shoddy cigarettes, and strive to bring them to justice during special operations. Supervisory organs at all levels should strengthen the system of administrative accountability, and seriously investigate and deal with acts such as state staff participating in or sheltering the activities of manufacturing and selling fake and shoddy cigarettes and neglecting their duties and engaging in malpractices for selfish ends in the process of cigarette counterfeiting; In case of major or malignant cases caused by passive slackness and ineffective work, the responsible persons of local governments and relevant responsible persons shall be investigated according to law. Provincial Radio and Television Group should pay close attention to the installation of large-capacity three-phase electricity and inform the provincial public security department in time.

　　(3) Strengthen publicity and guidance, and strengthen supervision by public opinion.

　　Governments at all levels and relevant departments should, with the help of television, radio, newspapers and other news media, strengthen the publicity and reporting of the special campaign against cigarette counterfeiting this winter and next spring in accordance with the requirements of "highlighting key points, grasping opportunities and creating momentum", and focus on publicizing the firm determination, positive actions and remarkable achievements of our province in attaching great importance to cigarette counterfeiting, making unremitting efforts and severely punishing according to law, so as to form a strong publicity momentum in the whole society and deter criminals. It is necessary to carry out publicity and education on laws and regulations among the broad masses, obtain the support and cooperation of the masses, especially do a good job in ideological education of village and town cadres in key areas, earnestly implement the responsibility system for counterfeiting, and promote the in-depth development of cigarette counterfeiting work.

　　On May 15th, at the press conference held by the State Council Press Office, the National Bureau of Statistics released the main index data of national economic operation in April. The data shows that in April, the production sector grew steadily, the market demand continued to expand, the employment situation continued to improve, consumer prices rose moderately, the supply-side structural reform was further promoted, the old and new kinetic energy was accelerated, and the quality and efficiency of economic operation were further improved.

　　Xing Zhihong, spokesperson of the National Bureau of Statistics and director of the National Economic Statistics Department, said that although some indicators declined in April, there were many positive changes in the relationship between supply and demand, quality and efficiency, and market expectations in economic operation. "Stability" was the main tone, "progress" was the key word, "good" was the general trend, and the national economy was expected to continue to maintain a stable and positive trend.

　　The main tone of "stability" has not changed.

　　The data shows that the growth rate of some economic indicators declined in April.

　　"This is mainly due to this year ‘ May Day ’ The small holiday is ahead of schedule and the working day is reduced by one day. " Xing Zhihong said that if we compare the growth of economic indicators in April with January-February and last year, we can find that the performance of relevant indicators is not weak. Taking industry as an example, in April, the year-on-year growth rate of industrial added value above designated size was 0.2 percentage points faster than that in January and February, and 0.5 percentage points higher than that in the same period last year. Among the monthly growth rates since 2015, the growth rate of 6.5% is also at a high level.

　　"The decline in the growth rate in the month has not affected the steady development trend of the cumulative growth rate." Xing Zhihong said that the cumulative industrial growth rate from January to April was 6.7%, which was basically the same as the 6.8% in the first quarter; The cumulative growth rate of retail sales of social consumer goods was 10.2%, 0.2 percentage points faster than that in the first quarter. It can be seen that the slight decline of some economic indicators in April is not a trend change, but a small fluctuation within a reasonable range and an expected range.

　　Xing Zhihong said that from the four important indicators of economic growth, price level, employment status and balance of payments, China’s economy continued to operate steadily in a reasonable range, and the main tone of stability remained unchanged, achieving stable economic growth, stable employment, overall stable prices and relatively stable balance of payments.

　　The strength of "entering" is increasing.

　　Xing Zhihong said that in April, China’s economic operation was intensified, structural adjustment continued to advance, and the momentum of transformation and upgrading was good. The "three to one, one reduction and one supplement" was solidly promoted, and the policy effect was further revealed.

　　— — In terms of capacity reduction, steel production increased by 1.7% year-on-year in the first four months, and the growth rate dropped by 0.4 percentage points compared with the first quarter. Cement and raw coal production increased by 0.7% and 2.5% respectively. At present, the steel production capacity is 31.7 million tons, and the coal production capacity is 68.97 million tons, achieving 63.4% and 46% of the target tasks for this year respectively. In terms of destocking, the area of commercial housing for sale nationwide decreased by 7.2% at the end of April, which was 0.8 percentage points higher than that at the end of March. In terms of deleveraging, the asset-liability ratio of industrial enterprises above designated size was 56.2% in March, down 0.7 percentage points year-on-year.

　　— — In terms of cost reduction, from January to March, the cost per 100 yuan of main business income of industrial enterprises above designated size was 85.25 yuan, down 0.15 yuan year-on-year.

　　— — To make up for the shortcomings, the investment in ecological protection and environmental management increased by 50.4% in the first four months, the investment in public facilities management increased by 28.4%, and the investment in water conservancy management, transportation and warehousing and postal services increased by 16.1% and 16.7% respectively.

　　"Since the beginning of this year, the leading role of innovation has improved, new kinetic energy has continued to grow and develop, and entrepreneurial innovation has a good momentum." Xing Zhihong said that in April, there were 556,000 newly registered enterprises nationwide, a year-on-year increase of 9.2%, with an average of 18,500 newly registered enterprises every day. New formats and new models have grown rapidly, and the proportion of online goods in the retail sales of social consumer goods has reached 12.9%, up 1.8 percentage points year-on-year. Driven by the rapid development of e-commerce, the volume of express delivery business is also growing rapidly, and it is expected to increase by 31.1% from January to April.

　　"Good" conditions are increasing.

　　Xing Zhihong said that since the beginning of this year, the positive factors in China’s economic operation have been accumulating, and the steady and positive development trend is sustainable.

　　From the perspective of supply and demand, although the year-on-year increase of PPI has declined in the past two months, the improvement of supply and demand in most industries continues and the market demand continues to expand. In April, the prices of 34 of the 40 industrial sectors were higher than the same period of last year, and the increase was further expanded; Among the 596 industrial products, the output of 419 products was higher than that of the same period of last year, with an increase of 70.3%; What is even more commendable is that the production and sales rate reached 97.6%, up 0.1 percentage points year-on-year, indicating that the relationship between supply and demand in the market continued to show an improvement trend.

　　"This improvement in the relationship between supply and demand is achieved in the context of structural reform on the supply side and the transformation of old and new kinetic energy. It appears on the premise that both supply and demand structures are optimized, and new supply is born through new demand, and new supply creates new demand, not just the result of cyclical factors." Xing Zhihong said.

　　"The upward momentum of the economy and the downward pressure of the economy coexist, and some long-term accumulated structural contradictions still exist." Xing Zhihong said that at present, China is in a critical period of speed shifting, structural optimization and kinetic energy conversion, and it still needs to pay close attention to new situations and new problems in economic operation.

Original Wang Xingfei Fictitious Time

Whether you choose chemotherapy, X-ray examination or heart transplantation, every medical decision is a risk.

From the first human blood transfusion more than 300 years ago to the development of vaccines in COVID-19 today, risks are accompanied by the emergence of every new treatment.

Blood transfusion, anesthesia, chemotherapy, vaccines, antibiotics, X-ray examination, organ transplantation, genetic engineering, biological agents, Dr. Paul Offit (author of The Story of Vaccine) started with nine great achievements of modern medicine and told the story of risks behind each medical progress this time.

In the 20th century, the average life expectancy of Americans increased by 30 years, largely due to the progress of modern medicine. At the same time, every medical breakthrough is accompanied by victory and tragedy.

Do we accept new technologies and when?

Faced with this medical uncertainty, our old friend, Dr. Wang Xing, the author of "Patient’s Family, Please Come" and other books, said: "In fact, although most technical risks are now very controllable, the probability of risks is still not zero, not to mention the exploration of new technologies. You will find that when a new treatment appears on social media, the most indifferent is actually the doctor. Not because they don’t accept new things, but because they understand the uncertainty behind new technologies. The doctor’s job is to try to play the most beneficial card for the patient on the premise of knowing the uncertainty. This is the’ life’ that doctors believe. "

Do doctors also believe in "life"? !

Wen | Wang Xing

(Peking University, Ph.D. in Oncology, Deputy Chief Physician, Department of Thoracic Surgery, Shanghai First People’s Hospital)

Do doctors believe in life? Really believe it.

Many doctors, including me, don’t necessarily have any religious beliefs, but most of them believe in fate. This is not a feudal superstition, such as not eating mangoes (busy) and eating apples (safe) when on duty, although many times we really want to do so. The "fate" that doctors believe is essentially probability. Because modern medicine is an uncertain science based on probability.

When a doctor is a rookie, he can be independent, not because of how many operations he can perform, how complicated situations he has handled and how to save the day, but because of his courage. At the beginning of the operation, there was nothing I was afraid to do, and I was full of momentum, but today, ten years later, I am afraid of a lot. This kind of cowardice is not simply to give up the challenge, but to recognize the probability.

Dr. Wang is at work. Tuyuan Wang Xing Weibo

Assuming that the probability of a risk is one in a thousand, and you treat at least 1000 patients in ten years, this risk will change from a small probability event to a high probability accident.

In recent years, immunotherapy has become more popular in the field of lung cancer. Because of some policies of benefiting the people, most of the immunotherapy drugs have dropped from the initial course of 10,000 yuan to around 1000 yuan. This is certainly gratifying, but it is a headache for doctors that when the price is lower than many auxiliary drugs to relieve vomiting, it will lead to a result-because patients lack the necessary understanding of the side effects of such drugs, they think that since this drug is not expensive, it is nothing to add.

On one occasion, the day before, we lamented that the patient was obviously better after taking the medicine for two days. The patient returned home happily and received news from the patient’s family the next day that the patient had left. From the experience, it is likely that there is an outbreak of immune cardiotoxicity, the probability is about 5%, there is no reason, and even the key markers can not be found to determine who is the 5%.

Young doctors are reluctant to talk about risks and think the probability is too low. But I will talk about the risks and let patients know that whether it is surgery or medication, we are all gambling. I still remember that a patient in the department suddenly fell to the ground when he went to the toilet the next day after surgery. After investigation, he found that it was an acute cerebral infarction, so he quickly rescued it and spent hundreds of thousands. The final outcome was a vegetative state, and the patient died soon.

Stills of In the World

It was originally a simple minor operation, but the patient lost his life. Despite the timely rescue, the patient’s lover expressed gratitude to us, but the family members still questioned us-

"Should surgery be done?"

"If the operation is not done, can the patient live for many years?"

"Why didn’t you emphasize with your family that you would have a cerebral infarction before the operation? If you knew there was this risk, we wouldn’t be in a hurry."

If I were a family member, I would ask the same question. No way, the surgeon’s job is to bury his emotions in a grave that belongs to his own heart and continue to work with a cold mask. But the more you work, the more timid you are, and the more you will nag patients about risks, instead of boasting about your strength and downplaying the operation.

I hope more people will read this book precisely because it is not preaching, but telling people with facts that medical risks are a problem that cannot be ignored.

Although medicine has developed from witchcraft of offering sacrifices to ghosts and gods to today, it is still full of many uncertainties. This is the origin of the title, gambling on life, or literally translated as-you have to gamble on your life.

This is no exaggeration. Nowadays, technologies that look very mature: blood transfusion, antibiotics, vaccines, anesthesia … These medical inventions not only bring about the improvement of people’s well-being, but also bring disastrous consequences.

Stills of Everything About Dr. Tang

If the key word of the author’s The Story of Vaccine is "cost", then the key word of Gambling Life is "uncertainty".

At the time of writing this book, the COVID-19 epidemic was raging all over the world, and all countries were on the track of vaccine, hoping to develop a unique vaccine, so that their countries could gain great advantages in this era. On April 7th, 2020, FDA approved an antimalarial drug named hydroxychloroquine for the treatment of Covid-19 infection in the absence of research results on drug effectiveness. Many people, including the then president of the United States, think that what harm can it do to try? Unfortunately, many research results show that hydroxychloroquine can neither treat nor prevent Covid-19 infection, and about 10% of drug users have severe arrhythmia. Two months later, the FDA withdrew the drug recommendation.

It can be said that one of the purposes of this book is to accuse the American government of ignoring the potential risks of new medical technologies in order to "win". Different from the history of western medicine which is narrated according to time, Gambling Life has no intention of exaggerating the success and tragedy stories behind nine modern medical advances, but conveys a profound lesson to us-whether, when and how we should accept new technologies.

This book tells readers with cold figures how the hidden bugs in the beautiful medical discoveries in the name of cure have led to disasters step by step. In the process of reading, I was deeply touched. Medical study only made me see the increasing life span of human beings, but I didn’t see that the flashes in medical history superimposed the unique arrogance of human beings, which made history trample on bones and blood and tears again and again.

Human discovery of medicine is often accompanied by several kinds of mistakes:

The first category is insufficient cognition.

The author takes blood transfusion as an example. At first, people learned to transfuse blood from cattle and sheep. When an accidental transfusion of human blood succeeded, they fell into a gambling game, because after transfusion, there was a certain probability that people would die. Today, we know that people have ABO blood type and Rh blood type, and only the correct blood transfusion method can be established. After people thought that they had discovered the natural law and started blood transfusion, they were educated again, because the disaster caused by the spread of hepatitis B and AIDS caused by blood transfusion was far more serious than before. You will find that the more ordinary people are, the more confident they are, and the more confident they are, the greater the cost.

The second category is that the pace is too big and there is a lack of supervision.

Known as "one of the most serious large-scale poisoning incidents in the 20th century", the protagonist is an antibiotic called sulfanilamide, which is still commonly used today. At that time, four weeks after the drug was put on the market, 353 people took it and 105 people died, including 34 children. Finally, it was found that the problem was not sulfanilamide, but the solvent of the drug. The solvent contains lethal diethylene glycol, which will cause nephrotoxicity. On March 5, 1938, President Roosevelt signed the Food, Drug and Cosmetics Act. Since then, American pharmaceutical companies have been required to list all drug ingredients on the labels and fully carry out product safety tests before they can obtain the marketing permission of the FDA.

The third category is "a dead horse is a living horse doctor".

The most typical example is biotherapy. In the Wei Zexi incident, Wei Zexi tried biological therapy in the treatment of chondrosarcoma with a desperate mentality, and eventually he lost both money and money. The effectiveness of many seemingly "new drugs" and "new therapies" has not been fully verified, and the huge temptation of fame and fortune brought by a star therapy has also driven doctors to ignore ethics and regulatory processes to promote clinical trials. This "two-way trip" to human trials is disastrous, such as the incident of genetically editing a fetus that made a lot of noise a few years ago. These experiments will bring unpredictable and huge risks to individuals and human beings. The author thinks that we must firmly control the brakes under our feet.

via:www.sagarhospitals.in

The fourth category is the false confidence generated by animal experiments.

A successful heart transplant for chimpanzees does not mean that people will succeed. There are great species and individual differences between species and people. Social media often reports that a drug has played a good role at the cellular and animal levels, and it sounds as if human beings are about to conquer a certain disease. However, as long as graduate students who have experienced basic scientific research and training know that there is a huge gap between drugs from outside to inside, and from animals to people. What is effective at the cellular level may not be effective at the animal level, and what is effective at the animal level may not be effective in human trials, and even lead to a series of chain reactions. The exquisiteness of the human body also determines that any method of changing the structure and adjustment of the human body is bound to have defects.

Gambling on Life is a sober book, which refers to the U.S. government, which is eager to promote large-scale clinical trials without evidence, and hopes that every struggling patient can remain rational during treatment. In the book, you will learn that in the history of medical development, people who have been drugged may or may not fall asleep; People who have been vaccinated may resist the virus or die of the vaccine itself; Even blood transfusion, a common operation in modern society, was once a gamble.

Stills of "Emergency Room Story"

No one wants to gamble. It’s like a patient asking me if I can be cured. If I answer "It depends on my life", it will probably cause a contradiction between doctors and patients. In fact, although most technical risks are already very controllable, the probability of risks is still not zero, not to mention the exploration of new technologies. You will find that when a new treatment appears on social media, the most indifferent is actually the doctor. Not because they don’t accept new things, but because they understand the uncertainty behind new technologies.

The doctor’s job is to try to play the most beneficial card for the patient on the premise of knowing the uncertainty. This is the "fate" that doctors believe.

Author/Tank

In the film market in 1996, with the gradual popularization of television in ordinary families, journalists who reported films turned their attention to television. Similarly, social investors and institutions who like movies have also scattered their money bags on TV, which has led to TV dramas becoming a hot topic for film and television audiences. The film has only become a "minority carnival" in some first-and second-tier cities.

However, the film reform is still going on. The opening of the Sixth Plenary Session of the 14th CPC Central Committee, the convening of the National Film Work Conference and the promulgation of the "Regulations on Film Management" issued by the State Council have subtly changed the film market. In addition, it was also from this year that 5% of the movie box office was drawn as a special fund. Prior to this, the special fund was 5 cents per movie ticket, and with the average ticket price exceeding that of 2 yuan in 1996, this rule was improved accordingly.

However, the film market in 1996 was not as stable as expected.

The main theme film won the domestic film championship,

But was criticized by the leaders.

　 　　

Compared with the box office performance of record-breaking domestic films such as Red Cherry and Sunny Days in 1995, the domestic film market in 1996 can only be described as a fiasco. On the one hand, it may be because the large-scale influx of imported sub-accounts has raised the taste of the audience. On the other hand, it is really the quality of domestic films.

Indeed, since 1995, when imported blockbusters officially stimulated the film market in China, many state-owned studios also fell into panic, and both their investment ability, market grasp and internal management of enterprises were in an embarrassing situation. Even more than half of the state-owned studios can only maintain the situation by selling factory logos, renting venues and charging staff to lend labor fees. It is precisely because of the overall sluggishness of the domestic film market that in March of that year, the working conference of the National Film Bureau was held in Changsha. The market prospect of domestic films was discussed.

At the meeting, China filmmakers put forward the requirements of the boutique strategy, specifically the "Ninth Five-Year Plan", that is, during the "Ninth Five-Year Plan" period, 10 films were made every year, and a total of 50 boutique films were made in five years.

However, the "Ninth Five-Year Plan" has not become the turning point of China’s film quality, and the pressure of the film bureau leaders on various studios has not turned into the motivation of quality, but has become a misunderstanding of the creative concept. After the meeting in Changsha in March, studios quickly adjusted their creative themes, and at one time a large number of biographies describing the heroes of the times almost became hot topics. Because of the low production cost, many films gradually came out after two or three months. But it has become a new disaster in the history of China movies.

In 1996, among the top ten box offices in China, only one domestic film entered the list, ranking ninth, and it was also the main theme film "Kong Fansen" with group ticket bonus. The film produced by Shandong Film Studio is expected to reach 60 million party member X2 yuan (average ticket price) = 120 million box office before release, setting a new box office record for domestic film history, but the film ended with only 36 million yuan.

In the academic journal The Art of Film, which is sponsored by the China Federation of Literary and Art Circles and specializes in film criticism and film theory research, Mr. Gao Jun commented that China doesn’t need too many domestic films of the type of Kong Fansen-"The hero theme can take many forms, including poetry, radio dramas, feature films, reportage, etc., and the film art has its own special rules, so it is not necessary to make all films."

The relevant leaders of the Film Bureau also criticized at the conclusion meeting at the end of the year, arguing that Kong Fansen had nothing to do with the film marketization, and even announced the water injection rate of the film. "Red-headed documents are pioneers, and group booking is the main source of its box office. According to the data reported by more than 20 provinces across the country, only about 5% of the audience pay for their own movies, while the proportion in Beijing is even only 0.51%." As a result, the situation that the film is full of seats is very serious throughout the country, wasting a lot of party fees and union dues as a supplement to the film market, which is contrary to the development law of socialist market economy.

To the surprise of all filmmakers at that time, 23 years later, such films have become the absolute mainstream of the domestic film market.

China Film lost its monopoly on imported films.

　 　

The discussion about China Film’s monopoly on imported sub-accounts has been discussed since 1994. Later, we know that the establishment of Huaxia in 2003 partially ended the monopoly of China Film’s import sub-accounts, but in fact, in 1996, the relevant reforms had tried to break this deadlock.

In 1996, 54 imported films were issued nationwide, of which 51 were issued by China Film, and the other three were Long Film, North Film and Shanghai Film, each of which issued some accounts.

However, the practice in those days was not dominated by these three state-owned companies. Instead, China Film Company still signed contracts with foreign investors, and then the three state-owned film companies signed agency distribution contracts with China Film Company respectively, and then distributed them independently throughout the country. Changying, Beiying and Shangying respectively chose Future Water World, The Game of the Brave and Toy Story to distribute in different accounts throughout the country. All three films have achieved good results, but this distribution model has not been systematically promoted on a large scale afterwards.

Jackie Chan’s never to lose 4, the box office champion in 1996, was translated into Bai Jinlong and introduced to the mainland of China in that year. Like Hongfan District, this film was also introduced during the Spring Festival in parallel with the Hong Kong market. Although the film did not achieve the success of "Hong Fan District", it still achieved 80 million box office results. In terms of imported movies, action movies still occupy the dominant position in the market, such as Tornado, Broken Arrow, Game of the Brave, Adventure Island, Mission Impossible, Future Water World, etc. Except The Bridges of Madison County, all other imported movies are action, adventure and sci-fi movies, which are basically consistent with the current imported film market. Among the Hong Kong films, Jackie Chan’s film is the most appealing, which has obvious advantages over other films.

In first-and second-tier cities, imported films have become the absolute main force of the market. In Beijing, Shanghai and Guangzhou, the box office revenue of imported films has reached more than 70-80% of the whole year. This phenomenon will continue for more than five years.

Market polarization is serious,

Where is the next step of reform?

　 　

With the gradual opening of the market, the competition intensifies. The polarization of China film market is becoming increasingly obvious.

In addition to the polarization of box office volume between domestic films and imported sub-accounts films, the polarization of ticket warehouse market is also intensifying. Developed provinces and big cities began to occupy more and more market share. Take the comparison between 1995 and 1996 as an example: among the 32 provinces, municipalities and autonomous regions in China, the top five provinces and municipalities accounted for 49% of the total box office in 1995, and the top ten accounted for 68%; In 1996, the top five provinces and cities rose to 56%, and the top ten provinces and cities rose to 75%, and the gap was getting bigger and bigger.

The beginning and end effects of the cinema are becoming more and more obvious. In 1996, there were about 500 cinemas in China, and the top 100 cinemas accounted for more than 35% of the box office. Of course, this was the overall trend of reform and opening up at that time. Let some people get rich first, that is, let some cities or cinemas prosper first. Polarization is also a normal phenomenon caused by fierce competition in the market.

Star Studios, since 1996, have also received more and more attention from the industry.

Among them, Shanghai Daguangming Studio is the first studio in China. This cinema alone has an annual box office output of 20 million, which is 1.69% of the national box office. The capital cinema, which is the number one in Beijing, scored exactly 20 million in 1996.

However, compared with the polarization of ticket warehouses, how to really produce good domestic blockbusters became the most puzzling problem for China filmmakers at that time. The problems faced during the period of institutional reform of the film industry were complicated, and how to carry out macro-control. The "Ninth Five-Year Plan" failed, and the rule that the number of domestic films and the proportion of films should account for more than two-thirds of the overall market at Changsha Conference has almost become a dead letter, but the road of "boutique strategy" for domestic films cannot be changed. Maybe the movie market in 1997 will give us a surprise?

　　A group of hound lovers in Sichuan met through the Internet and gathered in the "Wildlife Protection Station" network group in the name of protecting wild animals, but they have been carrying hounds and shotguns in Jiuzhaigou for a long time to round up and kill wild animals. Over the years, many endangered national key protected wildlife have fallen under their guns.

　　On April 21st, The Paper learned from the Forest Public Security Bureau of Jiuzhaigou County, Sichuan Province that the eight hound lovers had been arrested and brought to justice, and now they have been transferred to the procuratorate for examination and prosecution on the crimes of illegally hunting and killing precious and endangered wild animals, illegal hunting, illegal manufacturing of guns and illegal possession of guns.

　　According to the police investigation, in recent years, Xu Mouqiang, a villager from Balang Village, Yuwa Township, Jiuzhaigou County, went hunting in the mountains for 15 times alone or in partnership with others. Among them, many national second-class protected wild animals such as gazelle and red-bellied pheasant were hunted.

　　Wild animal samples found by the police from Xu Mouqiang’s home The pictures in this article are all provided by Jiuzhaigou County Forest Public Security Bureau.

　　16 pieces of wild animal meat were found in the freezer.

　　On December 17, 2019, the police of Yuwa Police Station of Jiuzhaigou County Forest Public Security Bureau in Sichuan Province received a report that Xu Mouqiang, a villager in Balang Village, Yuwa Township, illegally hunted wild animals. After receiving the police, Jiuzhaigou Forest Public Security Bureau immediately organized the police to investigate.

　　According to the police investigating the case, on December 18, 2019, the police searched Xu Mouqiang’s home according to law. During the search, 16 pieces of suspected wild animal meat were found in the freezer of his living room, and 1 piece of suspected wild animal fur, 1 suspected shotgun, 1 air nail gun and 3 knives were found at home. Suspected hunting bullets, shell casings, air bullets, steel balls, air nail bullets, 21 fast bullets and 3 knives.

　　The shotgun found in Xu Mouqiang’s home

　　On December 18, 2019, Xu Mouqiang took the initiative to go to the Jiuzhaigou County Forest Public Security Bureau for an inquiry. After the case, the suspect Xu Mouqiang truthfully confessed the illegal hunting of wild animals, the manufacture of guns and the illegal possession of guns. After investigation, in recent years, Xu Mouqiang hunted 15 times in the mountains by dogs, shooting, etc., killing 1 blue sheep, 4 mountain donkeys, 1 wild boar, 2 Sichuan pigs, 18 pheasants and 1 green deer.

　　Jiuzhaigou County Forest Public Security Bureau entrusted Sichuan Nanshan Forestry Judicial Appraisal Center on January 7, 2020 to identify the relationship between species and protection level samples of suspected wild animals involved in the case. The identification results show that among the suspected wild animals involved in the case, there are 2 mountain donkeys, 1 scientific name gazelle and 1 scientific name impala, which belong to the national second-class key protected wild animals. There are also 8 pheasants, including 2 blue pheasants, 3 spoon chickens and 3 red-bellied pheasants, which also belong to the national second-class key protected wild animals. In addition, three green deer and Sichuan pigs belong to three animals, that is, terrestrial wild animals protected by the state, which are beneficial or have important economic and scientific research value.

　　According to the police handling the case of Jiuzhaigou Forest Public Security Bureau, The Paper was told that among the eight suspects involved, five were natives of Jiuzhaigou County, Aba Prefecture, one was a cattle dealer in Pingwu County, Mianyang, and the other two were Meishan people who lived in Chengdu for a long time and mainly engaged in the pet dog business.

　　Because of their common interest in training hounds, these eight people established a WeChat group of "Wildlife Protection Station" through Aauto Quicker and other networks. It’s called wildlife protection, and in fact, they all communicate and plan to kill wild animals.

　　The Paper noticed that the police also found a banner in Xu Mouqiang’s home, which read: Give it to the hound team of the mountain dog brothers, "Together Brothers, good faith service" was given to the flag bearer and the hunter was Zhou Mouquan.

　　The hound team received a banner.

　　According to the police investigating the case, these people also trained hunting dogs to sell, which was a pennant given by a person who bought hunting dogs. Because of their common hobbies, they often struggle to hunt together.

　　According to the investigation by the police, Xu Mouqiang went hunting 15 times in the mountains alone or in partnership with others in violation of the wildlife protection laws and regulations. Most of the hunting places were in Balang Village where he was located, and 12 of them took hunting dogs to participate in the round-up.

　　Among the three guns seized by the police from Xu Mouqiang’s home, the single-barrel shotgun was borrowed from Yang Decheng, the air gun was borrowed from Yang Shiming, and the nail gun was modified from the nail shooter and seamless steel pipe he bought online.

　　At present, the case has been transferred to the People’s Procuratorate of Jiuzhaigou County for prosecution, and 8 suspects involved in the crime of illegal hunting and killing precious and endangered wild animals, illegal hunting, illegal manufacturing of guns and illegal possession of guns.

　　　　　　 CCTV News:Israel local time today (March 2) morning, that is, Beijing time today (March 2) afternoon, Israel’s 23rd parliamentary elections began to vote. At present, 29 political parties and coalitions of political parties have decided to stand for election. According to the latest polls, the Likud Party, the largest right-wing conservative party in Israel led by the current Prime Minister Benjamin Netanyahu, and the Blue and White Party, the middle party, rank high and have equal strength.

　　　　　　 This election is the first time that Israel has held a general election for the third time in less than a year. In April and September 2019, Israel held the 21st and 22nd parliamentary elections. After two sessions of parliament, they were dissolved because of the failure to form a cabinet.

　　　　　　 Israel is a parliamentary country, with a total of 120 seats in the parliament, and political parties with more than half of the seats can form a separate cabinet. However, due to the proliferation of small and medium-sized parties, there has never been a single party forming a cabinet in Israeli history.

　　　　　　 [News Background] It is difficult to form a cabinet. Israel has held three general elections in less than a year.

　　　　　　 Due to the serious differences between parties and the difficulty in reconciling interests, Israel has been deadlocked in forming a cabinet after the first two general elections, and the new government has always been "difficult to produce", which has also led to the "strange phenomenon" of Israel holding three general elections in less than one year for the first time in history.

　　　　　　 On April 9 last year, Israel held the 21st parliamentary election. Although Netanyahu, the leader of Likud Group and the current Prime Minister, obtained the right to form a cabinet, he failed to successfully form a ruling Coalition within the prescribed time limit. The reason is that the right-wing party "Israel is our homeland" led by former Israeli Defense Minister Lieberman is difficult to balance the interests of several other religious parties, which led to the "abortion" of forming a cabinet and forced the parliament to dissolve and hold another general election.

　　　　　　 After the 22nd parliamentary election held on September 17th last year, Israeli President rivlin authorized Netanyahu and the leader of the "Blue and White Party" Ganz to form a cabinet, but their efforts to form a cabinet still ended in failure because of the great differences between the parties. Lieberman called for the formation of a "broad and free coalition government" composed of Likud Group, Blue White Party and Israel is our homeland. However, the negotiations among Netanyahu, Ganz and Lieberman failed to reach an agreement.

　　　　　　 Compared with the previous two general elections, the third general election to be voted today has added several uncertainties.

　　　　　　 First of all, on January 28th, the United States announced the so-called "New Middle East Peace Plan" to promote the settlement of the Palestinian-Israeli issue, which was explicitly rejected by the Palestinian side, and the tension between Palestine and Israel escalated again. And about half of Israelis believe that this move of the United States aims to intervene in Israeli elections and help Netanyahu win — — But not long ago, Netanyahu, suspected of corruption, was formally charged, and the case will be heard on the 17th of this month, half a month after the general election, which is very likely to affect voters’ voting intention.

　　　　　　 At the same time, there have been some changes in the position of Netanyahu’s main rival Ganz — — Although "refusing to face trial with Netanyahu ‘ Take turns to govern ’ " His position has not changed, but Ganz turned to oppose the "Joint List" party of the Arab political party alliance to join the Coalition government and supported the so-called "New Middle East Peace Plan" of the United States, which may make the "Blue and White Party" lose some votes of the center-left voters.

　　　　　　 [News Watch] I am afraid that the deadlock in the formation of the cabinet is still difficult to break.

　　　　　　 At present, analysts are generally worried that after the end of the third general election in less than a year, Israel may still face a "tug-of-war" to form a cabinet, which will lead to the deadlock of forming a cabinet again.

　　　　　　 Many polls before the election showed that Likud Group and Blue and White Party are still evenly matched, and both sides may win about 33 seats, with a difference of at most two seats — — The third general election may still be difficult to change the political deadlock after the previous two general elections.

　　　　　　 In the previous two general elections, the Likud Party and the Blue-White Party tried their best to win over their allies, but they failed to win at least 61 of the 120 parliamentary seats needed to form a cabinet. It can be seen that after the third general election, the two parties still need to win over the "Israel is our home" party led by Lieberman. However, it is still very difficult for both Netanyahu and Ganz to pull Lieberman into their respective camps.

　　　　　　 As domestic analysts in Israel have said, "it is hard to see substantial changes in the Israeli political situation after the third general election", and the dystocia of the new government will directly affect the deliberation of Israel’s national budget and the introduction of important decisions. Israel’s political system is facing a serious crisis, and some people even have to silently accept the possibility of holding the fourth general election next — — If we want to break the deadlock in the formation of the cabinet, we must make a decisive compromise between the various parties.

You can’t always stay at home, but you have to travel, or commute to work, or go on business trips, sightseeing, and travel can’t be separated from subways, railways and highways. When you take subways, trains and highways, have you ever wondered: How are those tunnels dug through them?

Early tunnel excavation was manual plus blasting.

In the past, the way of tunnel excavation was manual excavation and blasting. For soil layer and gravel geology, manual excavation was used, and tools such as pickaxe and shovel were used to excavate the tunnel face. As far as rock geology is concerned, pickaxes and shovels can’t be dug, so it is necessary to use explosives to blast rocks at the tunnel face, and then transport the gravel out of the tunnel.

"Face" is a civil construction term, which refers to the excavation face that keeps advancing during tunnel construction.

As far as subway tunnels are concerned, in the past, the "open excavation and landfill method" technology was mostly adopted, that is, the street was destroyed first, and a ditch was dug by uncovering the cover, and then the tunnel wall was poured in the ditch. After the tunnel was built, it was buried and compacted with earthwork, and the street was repaired again. In the early days of Chinese mainland, the subway tunnel was excavated by "open excavation and landfill method", and later the "shield machine excavation method" was adopted. Shield machine was used to dig tunnels in the construction of Guangzhou’s first subway line (Line 1).

In the past hundred years, shield machines have gradually become popular in tunnel excavation. At present, shield machines are basically used in long tunnel excavation.

Britain used a shield machine to dig tunnels in 1825.

"Shield machine" is a name in China, generally known as "tunnel boring machine" (TBM) internationally, and "mole" in civil engineering jargon, because it digs holes underground like a mole.

In 1825, Britain used a shield machine when digging the Thames Tunnel. This shield machine was invented by Sir Mark issam Bald brunell, a French-born British engineer, and he applied for a patent for the shield machine. The Thames Tunnel is 396 meters long and passes through the Thames River in London.

In 1845, the international railway from France to Italy was opened. This railway ran across the Alps, and it was necessary to dig the Freres Tunnel at an altitude of 1,123 meters. This tunnel was 14 kilometers long, which was the longest tunnel in the world at that time. The tunnel ran through the Freres Peak at an altitude of 2,932 meters, that is to say, the maximum thickness of the rock above the tunnel was 1,809 meters.

In order to build this tunnel, Henry Joseph Mauss invented the "mountain cutting machine", which was manufactured in an arsenal near Turin, Italy in 1846. The "mountain cutter" looks like a locomotive, with more than 100 vibrating drill bits in front, which are used to smash the rocks on the face. "Mountain cutting machine" already has some functions of modern shield machine.

In 1853, ebenezer Talbot, an American, applied for the patent of shield machine, and the patent name was "Tunnel Boring Machine".

In 1870, john D bruton, an Englishman, developed and manufactured a shield machine with cutter head, which is very close to the shield machine widely used now.

In 1875, the French National Assembly passed a bill to build the English Channel Tunnel, and the British shield machine was selected for excavation. From June 1882 to March 1883, the shield machine excavated 1882 meters on the British side; Alexander Lavalle, a French contractor who built the Suez Canal, used a shield machine to dig 1,669 meters on the French side. Practice has proved that the efficiency of tunneling with shield machine is very high. However, the project was terminated in 1883 because France was later worried that Britain would use the English Channel Tunnel to attack France.

The success of shield machine in the English Channel Tunnel has inspired many civil engineers. In 1883, Britain used a shield machine to dig the tunnel under the Mersey River from Biegenheit to Liverpool, with a diameter of 2.1 meters and a length of 2 kilometers.

In the 20th century, people constantly improved the shield machine. Nowadays, all kinds of shield machines are constantly running in tunnel projects all over the world every day.

How does the shield machine dig the tunnel?

It is easier to understand the working principle of shield machine from its international common name "tunnel drilling rig": it is a big drilling rig that drills a hole in the ground or mountain.

Shield machine can be regarded as the largest construction machinery in civil engineering, with a large diameter of 178 meters and a length of more than 100 meters. The front of the shield machine is a huge cutter head with cutter head array. When driving, the cutter head rotates to cut the earth and stone on the tunnel face, and the muck flows into the muck bin from the gap of the cutter head, which is conveyed to the belt conveyor by the screw machine, and then transferred to another longer belt conveyor to transport it to the muck disposal site outside the tunnel, or transported to the tunnel by the track muck truck.

Readers with a little common sense should understand that if there is no thrust behind the cutter head, it is impossible to cut the earth and stone on the face. So, how to give the cutter head thrust?

This thrust comes from the hydraulic jack of the shield machine. If the tunnel is excavated on hard rock, two huge hydraulic jacks on the shield machine lean backward against the rock walls on both sides of the excavated tunnel and push the cutter head forward to cut the tunnel face.

If the tunnel is dug in the soft geological layer, the above method cannot be used, because the hydraulic jack will sink into the soft tunnel wall and cannot provide thrust. At this time, it is necessary to use another method to make several small hydraulic jacks push against the lining segment installed at the back at the same time to provide thrust for the cutter head horizontally forward, which is also a common shield method in subway tunnels at present.

The lining segment is the reinforced concrete precast member on the tunnel surface that we can see with our naked eyes in the tunnel. These segments are made in the ground reinforced concrete precast yard. After the segment is transported into the tunnel mouth, there is no need for manual intervention, and the transportation to installation is completely automatic.

The width of the lining segment should match the distance that the hydraulic jack advances each time, that is to say, the width of the segment is as many centimeters as the hydraulic jack advances each time. When the hydraulic jack is pushed to the end, the cutterhead stops rotating to cut the tunnel face, and segments are assembled around the tunnel in the shield section of the shield machine. The segment assembling machine on the shield machine is as dexterous as a human hand, movable, rotatable and retractable, which can assemble segments in place steadily and safely with accuracy of millimeter level.

When assembling a segment, several hydraulic jacks responsible for jacking the segment will contract, leaving a certain space for assembling the segment. After the segments are assembled in place, the hydraulic jack will stretch out and gently hold it, and so on until all segments in this circle are assembled in place. At this point, all the hydraulic jacks began to pressurize evenly, and together with the newly assembled segment, the cutter head was pushed forward by the reaction force to continue cutting the working face and move forward.

During the construction of the shield machine, the cutterhead cuts the tunnel face and assembles segments alternately, and the whole shield machine moves forward step by step under the push of the hydraulic jack until the tunnel is dug through. If the geology is soft, tens of meters can be excavated every day; If you encounter hard rocks, you can only dig dozens of centimeters every day.

The gap between the lining segment and the tunnel wall should be filled with mortar to reinforce the segment, maintain the stability of the whole lining and prevent water from leaking into the tunnel.

The series of complicated processes mentioned above are all completed automatically by the shield machine. There is a central control room in the shield machine, and all key parts of the shield machine have sensors, which transmit the collected data to the central control room. Operators can know the working situation of the shield machine through various data displayed on the display and intervene when necessary.

The cutter head on the cutter head should be maintained and replaced frequently. There is also a sensor on the cutter head. When the temperature of the cutter head rises to a certain value, it will send an alarm signal to the central control room.

How does the shield machine turn in the tunnel?

After reading this, some readers may ask, can the shield machine turn in the tunnel?

Of course you can. Most urban subway tunnels are excavated under the streets, and the tunnels are designed along the streets, with constant turns and "jumping up and down" according to the underground conditions. Highway and railway tunnels should also be selected according to landform, geology and hydrology, which also requires the shield machine to turn 360 degrees.

The turning of shield machine is realized by changing the cutting direction of cutter head with lining segment. Where a turn is needed, the width of each ring of lining segment is different. If turning to the left, the width of the right segment is designed to be wider than that of the left segment according to the turning radius. In this way, the hydraulic jack on the right will tilt the cutter head to the left to realize the left turning. If turning right, the width of the left segment is designed to be wider than that of the right segment according to the turning radius, so that the hydraulic jack on the left will tilt the cutter head to the right and realize the right turn. The steering principle of "jumping up and down" is the same as above.

At present, the largest shield machine in the world has a diameter of 17.5 meters.　　

On September 15th, 2006, the Niagara Tunnel, which was used for water diversion irrigation in Canada, was drilled. The tunnel was 10.2km long and passed 140m underground in Niagara Falls, Ontario, Canada. The shield machine used was "Big Becky" made by Robbins Company of the United States, with a diameter of 14.4m. The cutter head was driven by 15 motors with a power of 4.7 million watts (6,375 horsepower), which was the largest shield machine in the world at that time. The reason why tunnels should be dug in such a deep underground is to prevent shield construction from affecting ground buildings.

In 2011, the 5030-meter-long Spavo Tunnel near Florence, Italy was drilled. The rock shield machine used was Martina produced by Herrick Company of Germany. The shield has a diameter of 15.62 meters, a length of 130 meters, a weight of 4,500 tons, a cross-section of 192 square meters, a total power of 18 megawatts and a thrust of 40,000 tons. Herrick also designed a shield machine with a diameter of 19.25 meters, but it has not yet been built.

Bertha, a shield machine made by Hitachi Shipbuilding Co., Ltd. in Japan in 2012, has a diameter of 17.5 meters, a length of 110 meters and a weight of 7,000 tons. The cutter head has 260 cutter heads. This shield machine was ordered by the Washington State Transportation Bureau of the United States and used to replace the tunnel excavation of Alaska Viaduct on Highway 99 (the upper and lower lanes of the tunnel), which is by far the largest shield machine in the world.

Advantages and disadvantages of shield tunneling

There are many advantages in tunneling with shield machine. It is not affected by ground factors and can be constructed all day; It also does not destroy the ground buildings, cultural relics and natural environment, and belongs to ecological and environmental protection construction; Because the excavation, muck discharge and lining segment are all automated, a lot of labor is saved and the accident risk is reduced.

The main disadvantage of tunneling with shield machine is that the initial investment cost is too high. Most shield machines are customized according to tunnel design drawings, with long construction preparation period, high maintenance cost, and low economic benefits of tunneling short tunnels. Generally speaking, the tunnel length is more than 1 km, which has economic benefits.

Finally, the shield machine can not only dig circular tunnels, but also be designed to dig tunnels with arbitrary cross sections, such as rectangular tunnels and elliptical tunnels. People also use shield machines to dig water pipelines, sewage and drainage pipelines, and even power pipelines.

A starving baby, if the mother has other conditions such as insufficient milk, will usually be fed by other lactating mothers instead. This kind of behavior in humans is popularly called "wet nurse feeding", and scientifically it is defined as allomaternalbreastfeeding.

In fact, scientists have observed similar phenomena not only in humans, but also in rodents and primates. A recent study by scientists in China has further expanded the scope: the research team led by Zuo Fu, a professor at the School of Life Science and Technology of Central South University of Forestry and Technology, and Li Ming, head of the primate ecology research group of the Institute of Zoology, Chinese Academy of Sciences, obtained the evidence of the old world monkey’s maternal lactation for the first time. The research results were published on February 21st, Beijing time, in Science Progress, a sub-magazine of Science.

Breastfeeding behavior of Sichuan golden monkey. The pictures in this paper are provided by the research team.

In an interview with The Paper reporter (www.thepaper.cn), Zuo Fu said, "This is the first time to report that regular partheno-lactation exists in Old World monkeys, which has expanded the distribution of partheno-lactation in primates and made it appear in different groups such as proto-monkeys, New World monkeys, Old World monkeys and even humans."

Higher primates, that is, anthropophagus, include New World monkeys distributed in South America and Old World monkeys distributed in Eurasia (Old World). Previously, there was no report about the maternal lactation behavior of Old World monkeys. According to Zuo Fu, the research team started this new research in 2012 and observed it continuously for five years. The research was carried out in Dalongtan Research Base of Shennongjia National Park in Hubei Province.

The research base has a group of about 90 golden snub-nosed monkey. Sichuan golden monkey is endemic to China, with a golden fur. They are distributed in the forests at the junction of Hubei, Sichuan, Shaanxi and Gansu, and distributed in Minshan, Qionglai, Daxueshan, Xiaoliangshan, Qinling, Shennongjia and the northern slope of Motianling.

"We began to study the monkey group in 2006, and the researchers were able to identify all individuals over 3 years old in the group." Zuo Fu said that the birth of Sichuan golden monkey is basically concentrated in the period from March to May every year. Because the coat color and body shape of baby monkeys are similar, it is not easy to identify them, so there is no concern about whether there is maternal breastfeeding at first. "Until the spring of 2011, after accidentally finding a female monkey feeding two baby monkeys at the same time, the research team carefully observed the breastfeeding behavior of Sichuan golden monkeys in the group and found that the breastfeeding behavior of different mothers was more common."

This latest paper shows that in the field observation conducted by Zuo Fu et al. for five years in a row and after five farrowing seasons, 40 (87%) of 46 baby monkeys of Sichuan golden monkey were breast-fed by one or more non-mother monkeys, and 22 (48%) of 46 baby monkeys were breast-fed by at least two other mothers. This behavior of maternal breastfeeding mainly occurs in the first three months after the baby monkey is born.

The research team also found that 6 of the 46 baby monkeys did not receive maternal breastfeeding at all, and 4 of them died in the cold winter. In comparison, among the 40 baby monkeys that were breast-fed by at least one non-mother monkey, a total of 6 eventually died, and the mortality rate was greatly reduced.

It is worth noting that Sichuan golden monkey generally lives in temperate forests with high altitude, and it is extremely cold in winter for five months, and the food supply also has strong seasonal changes. Partheno-breastfeeding behavior may help baby monkeys fight against unfavorable living environment.

Zuo Fu said, "The behavior of maternal breastfeeding may provide energy support for the rapid development of baby monkeys after birth, so that the baby monkeys can feed in advance to achieve a good development state before the severe winter, and can successfully survive the winter of extreme low temperature and food shortage. This behavior may also provide energy support for the rapid development of the brain, which makes the brain capacity of golden monkeys relatively large."

Generally speaking, the behavior of maternal breastfeeding only occurs within three months or less after the baby monkey is born, and it almost stops when the baby monkey begins to eat natural food.

In addition, the research team also found that the maternal breastfeeding behavior in Sichuan golden monkey still follows certain principles. Baby monkeys can not suck milk in all non-maternal monkeys: the maternal breastfeeding behavior of Sichuan golden monkey only occurs between females who are related or breastfeeding each other.

It is mentioned in the paper that kinship-usually the "grandmother" or "aunt" of baby monkeys, or reciprocity plays an important role in maternal breastfeeding. About 90% female monkeys (25 out of 28) will breast-feed the cubs of other female monkeys who have breast-fed their own baby monkeys in the current or next year, which is similar to "reward".

Zuo Fu believes that the maternal breastfeeding behavior occurs between females who are related or cooperate with each other, and the mother will allow other females to contact the baby monkeys in the early stage of development, which is necessary for the infant-mother-maternal care relationship in the early stage of human evolution, so this study also provides a new perspective for understanding human evolution.
