Q: Network signal is a concern of users. What kind of planning does Bozhou Unicom have in network construction?

A: Network signals are indeed a concern of users, and China Unicom is constantly strengthening network construction. In 2021, we will further improve the key coverage of 5G networks in urban areas, counties, towns and industrial parks, and plan to build 598 5G base stations. By August 18th, 300 5G base stations had been opened, with a cumulative opening of 699, with an opening progress of 50.17%. It is planned to complete 70% of the 5G base station opening task by the end of August and 100% by the end of October. It is planned to jointly build and share 4G in Guoyang County with Bozhou Telecom in August. After sharing, there will be more than 500 4G base stations in Guoyang County, and both base stations will increase by 40%, forming a common and complete 4G network. By then, network coverage and user perception will be greatly improved.

Q: Is there any discount for Unicom to buy mobile phones now? Please give us a detailed introduction.

A: Now we have optimized the prepaid phone bill to send to the mobile phone. You don’t need to pre-store a large phone bill at one time, just ensure the daily package consumption, and you can enjoy the mobile phone direct drop or 0 yuan purchase activity after more than two years online; For example, if your family accesses the Internet and handles an ice cream package with a price of 159 yuan, as long as you promise to stay online for more than two years, you can get a 5G mobile phone with a price of about 2,300 yuan. Moreover, this package includes 40G national traffic and 700 minutes of national calls, and it can be shared by five people in the whole family. Each person only needs 32 yuan and a 500M-meter broadband, so it can be handled without any additional expenses, which is more cost-effective than pre-storing phone bills to send mobile phones.

Q: Now some friends around me have upgraded the 5G package. How to solve the 5G package if the traffic exceeds?

A: If the traffic is not enough, you can supplement the extra traffic by superimposing traffic packets. For example, you can order a 5G upgrade packet or a monthly traffic packet. The monthly traffic packet will increase according to your online time, and the longer the number is used, the more traffic; If another 5G upgrade package is ordered for one year, you can order popular video members such as iQiyi, Tencent, Youku and Mango tv for only 2.99 yuan per month, which can meet the traffic usage and enjoy more rights and interests. It is very cost-effective.

Q: Recently, I saw that Unicom can handle Gigabit broadband through activities and publicity in various communities. Can users who have already installed broadband directly upgrade?

A: At present, Bozhou Unicom has opened 10 Gigabit broadband communities in the city. You can enjoy Gigabit network speed as long as you apply for an ice cream package of 199 yuan or more. If you are already an ice cream user of Unicom and are using Unicom broadband, you can upgrade to Gigabit network speed directly as long as you go to the business hall to speed up. In order to facilitate the old broadband users, there are preferential activities for speeding up. Old users with a price of 199 yuan or more can speed up their broadband to 1,000 m per month with 1 yuan money, and packages with a price of 129 yuan or more and a price of 199 yuan or less can speed up to 1,000 m per month with 10 yuan. Users who are not ice cream users and speed up during the preferential period can upgrade their original light cats to gigabit light cats for free. For specific speed-up consultation and handling, please contact the surrounding Unicom business offices or consult community promoters.

Q: Recently, some users have consulted the column group and have been using Unicom numbers. What should I do if I want to install broadband?

Answer: You can inquire directly in the nearest business hall. If broadband service is included in your package, you can make an appointment to install it directly. If there is no broadband service, you can change it to a converged package with broadband and get a free broadband. Moreover, at present, for the old users of China Unicom to install broadband, we also give an extra 100 yuan electronic coupon without threshold, which can be used for shopping in Tmall and other shopping malls, which is equivalent to giving 100 yuan money directly. The activity time is limited. If you want to install broadband, you can apply to the nearest business hall as soon as possible, and we will arrange engineers to install it for you as soon as possible.

Q: Last time I heard a friend say that using Unicom broadband sometimes leads to traffic jams. What is the reason? Can you upgrade the network speed?

A: In this case, it is not ruled out that the long-term use of broadband, aging network cable, outdated routing equipment and other reasons may affect the broadband network speed to some extent. Recently, our company is also actively organizing network engineers to carry out public welfare on-site free testing activities in various communities. If it is convenient for your friends, you can also go directly to the nearest business hall or contact the account manager to make an appointment. We will arrange for Zhijia engineers to conduct on-site free testing and provide network solutions. We will comprehensively analyze the home network according to the user’s equipment, package and network environment, and then speed up broadband, replace gigabit routers and network cables according to actual needs, which will completely solve the user’s network problems.

Q: Now you need to open a member to watch videos and use some apps. Is there a package for sending members to Unicom numbers?

A: Yes, if you apply for or change the 5G Instant Ice Cream Package now, you will be given 5GPLUS Gold Edition members for free. You can claim one of the popular app members such as Tencent Video, Iqiyi, Youku, Tik Tok, JD.COM, Mango TV, QQ Music, Netease Cloud Music, Himalayan, Hungry and so on for free every month. If it is not enough to get one member every month, PLUS Gold Members can also buy other membership services at ultra-low preferential prices every month. In addition, there are free video color ring tones, AI voice assistants, exclusive network disks, direct drop coupons for mobile phones, etc. Members of 5GPLUS Gold Edition normally want to go to 29 yuan every month, and the annual fee is only 299 yuan, but the 5G refreshing ice cream package is a free gift to members of Gold Edition, so it is very affordable to use this package.

Question:

1. The mobile phone card is broken. Can I get a replacement card if I don’t go to the local business hall in the field now?

A: Yes, at present, China Unicom’s number supports card replacement in different places. You can apply for card replacement with your ID card at your own business hall.

2. I don’t need the number recently and want to stop. What should I do? What is the charge after the newspaper stops?

Answer: If the mobile phone number is temporarily unavailable, you can go to the business hall with your ID card, provide personal information through the APP client of China Unicom or call the customer service hotline 10010, and charge a monthly fee for 5 yuan/downtime after the suspension. However, you need to be reminded that the account must have enough balance. If the number balance is insufficient, the suspension will be turned into arrears, and the account will be automatically cancelled if the arrears are overtime for three months.

3. Usually, you have to go to the business hall to inquire about telephone bills and bills. Can you inquire by other means?

A: You can download the China Unicom APP, which is the original mobile phone business hall. After logging in with your mobile phone number, you can pay fees, inquire about phone bills, bills, redeem points, etc. China Unicom APP often carries out some preferential activities, so I suggest you pay attention to it.

4. What can be done if broadband is installed on the first floor and the second floor and wireless network cannot be used?

Answer: If your broadband is installed on the first floor, it will be slower to use the wireless Internet on the second floor because of the coverage area of the wireless network. I suggest that you install another router on the second floor, and only need to increase the 10 yuan fee every month, so that the Internet speed on the first floor and the second floor can be guaranteed.

5. When you use Unicom broadband, sometimes you get stuck. What is the reason? Can you upgrade the network speed?

A: Thank you very much for using Unicom’s business. In this case, it is not excluded that reasons such as long-term broadband use, aging network cable and outdated routing equipment may affect the broadband network speed to some extent. Recently, our company is also actively organizing network engineers to carry out public welfare on-site free testing activities in various communities. If it is convenient for your friends, you can also go directly to the nearest business hall or contact the account manager to make an appointment. We will arrange for Zhijia engineers to conduct on-site free testing and provide network solutions. We will comprehensively analyze the home network according to the user’s equipment, package and network environment, and then speed up broadband, replace gigabit routers and network cables according to actual needs, which will completely solve the user’s network problems.

6. There are often some telephone calls to sell real estate. Is the information leaked?

A: Thank you very much for reflecting this problem. Unicom strictly implements the Network Security Law of the People’s Republic of China, the Regulations on the Protection of Personal Information of Telecommunications and Internet Users (Order No.24 of the Ministry of Industry and Information Technology) and other industry regulations, as well as the Measures for the Management of Network and Information Security of China Unicom, and does a good job in protecting customer information. Please rest assured that Unicom will not have the problem of customer information disclosure.

In fact, there are many ways to leak information now. If you have consulted the relevant information of selling houses, renting houses and buying decoration products before, there is a risk of number leakage. It is also recommended that you strengthen your awareness of personal information protection and security every day.

Liu Ye accepted an exclusive interview with 1905 Film Network.

Special feature of 1905 film network Liu Ye has been very busy recently: recording a variety show called "The Birth of an Actor", in which he not only acts as a mentor to comment on players, but also plays scripts and roles challenging various routes from time to time; At the beginning of the month, Changying Group and Yaolai reached a strategic cooperation, and Liu Ye’s film director’s debut "Touching Jin Jun" was officially announced immediately; In the past week, he flew to Australia on the other side of the ocean and participated in the Asian unit award of "AACTA Aita Awards" as a judge.

　

During the intermission of the award ceremony, we also had a brief chat with Liu Ye about his current and upcoming work.

　

Liu Ye

In the summer of 2018, "Touching Jin Jun" started to consider inviting "the birth of an actor" players.

　

For some time, many mainland actors seeking breakthroughs have chosen the road of "acting well and guiding". Like his peers, Liu Ye expressed his desire to be a director a long time ago, and now, this desire is infinitely close to realization.

　

At the beginning of this month, Changying Group signed a strategic cooperation agreement with Yaolai Group. Among them, the film project "Touching Jin Jun", which was adapted from the big IP "Ghost Blowing Lights" series, surfaced. Liu Ye will be the first director in this work, and Jackie Chan will be the producer to escort it and play a role in it. The first novel challenges the big-scale production of magical themes. Liu Ye admits that he also had concerns: "I originally wanted to make a smaller one (scale), but Jackie Chan and investors think it is ok, so I say you just have to trust me."

　

And everyone’s trust and expectation for Liu Ye doesn’t stop there. As early as the most popular period of IP film adaptation, many people mentioned Liu Ye when talking about the "Ghost Blowing Lights" series, thinking that he was very suitable for the hero in the original work. After the N version of Hu Bayi appeared in various movies and online dramas, does Liu Ye intend to personally end up in the "Ghost Blowing Lights" directed by himself?

　

In the interview, he kept his mouth shut, saying that he could not expose the role candidate for the time being. However, the variety instructor is not in vain. Liu Ye revealed: "When I choose an actor, I first consider the play, which is attractive to the audience. There are several actors I like very much in The Birth of an Actor. As a director myself, I will consider looking for them (joining). " It is reported that "Touching Gold" will be officially launched in the summer of 2018, and it is expected to land in the cinema in 2019.

　

China filmmakers’ international presence is increasing, and they plan to cooperate with Australian later companies.

　

On the evening of December 6th, local time in Sydney, Liu Ye appeared on the red carpet and took the stage as an Asian unit judge. In his view, he was able to get this opportunity, largely thanks to the vigorous development of China’s film industry and market: "Our (industry and practitioners) presence is improving."

　

As a member of the industry, Liu Ye has experienced many changes. "Let’s go out and they are coming in. What China movies want to express, foreign audiences are also (slowly) feeling and understanding. " For the goal of "going out", Liu Ye is also a practitioner: a few months ago, he just finished the location shooting of the new drama "old boys" in Australia.

　

This process has enabled Liu Ye to have a deeper understanding of the local environment and the mode of cooperation with peers: "Australia has many different scenery, which is cheaper than filming in North America. For filmmakers in China, there is basically no time difference when filming here. " So, is there any plan to shoot "Touch Jin Jun" here? "We have finished watching the scene. I have considered New Zealand, but (cooperation with Australia) will mainly be in post-production. " Liu Ye said.

　　With the coming of summer, drinks to cool down and relieve summer heat have once again become people’s first choice. Natural coconut water is the "flow code" in the beverage industry in recent years. Not only do it often sell out of stock, but coffee, milk tea and other drinks made with coconut water often occupy the list of young people’s must-order. However, recently, some netizens discussed it hotly, because they bought coconuts that were opened in advance and drank coconut water inside, which caused discomfort. As a result, topics such as "Can you drink coconut water" and "Who is not suitable for drinking coconut water" have boarded the hot search.

　　Today, let’s take a look at the safety of coconut water, how to drink it is the healthiest, and who is the most suitable?

　　Drinking coconut water leads to vomiting, diarrhea and high fever?

　　The so-called coconut water is the clear liquid poured out from the coconut after it is cut open, which has a very light sweet taste and a unique natural flavor. Coconut water contains no fat, and the fat is all in the white coconut meat.

　　The reason why coconut water was on the hot search this time was because it brought some trouble. Netizens said that they bought a coconut with a pre-opened mouth and drank a few mouthfuls of coconut water, only to find that the coconut water was a little turbid. Then he felt dizzy and dizzy, and then he felt sick and vomited. After getting better, I didn’t go to the hospital for treatment, but I had a high fever the next day.

　　In fact, this high probability is caused by pathogenic bacteria or bacterial toxins in coconut water.

　　Originally, the coconut shell was tightly sealed to protect the coconut meat and coconut water inside and avoid the entry of external microorganisms. However, after opening, the coconut loses its sealability and will come into contact with the bacteria in the air and the bacteria on the opening tool.

　　Why is coconut after opening suitable for rapid propagation of microorganisms and bacteria?

　　Coconut water contains sugar, vitamins and minerals, which is suitable for rapid propagation of microorganisms. At the same time, coconut water, a "small fresh" fruit juice, has low acidity, and sugar and nutrients are directly dissolved in water instead of hidden in fruit cells, so its resistance to bacterial proliferation is too weak. It is weaker than orange juice, apple juice, tomato juice and other juices with certain acidity and polyphenols, so it is especially necessary to be careful.

　　If coconuts are stored at room temperature for a long time after opening, bacteria will multiply in large numbers, which may lead to bacterial food poisoning. Netizens found that the coconut water, which should have been clear, was a little turbid, which was the visual result caused by bacterial reproduction. This is exactly the same reason that egg soup, rice soup and noodle soup will go bad at room temperature.

　　Bacterial food poisoning may cause nausea and vomiting, abdominal pain and diarrhea, physical weakness, dizziness and headache, and even chills and fever.

　　Because the body is weak after food poisoning, other harmful microorganisms may take advantage of it, and there may be inflammation of the gastrointestinal tract and gums, or, as netizens have said, tonsils are in trouble again.

　　Deteriorated coconut water will produce mycotoxins?

　　Some people on the Internet say that the spoiled coconut water may produce Pseudomonas cocoanum, which will produce highly toxic mycotoxins. Because this case did not do microbial culture of coconut water samples, it is impossible to judge what kind of pathogenic bacteria or bacterial toxins caused the poisoning only by the symptoms.

　　It can only be said that coconut water contains carbohydrates. In an unsafe temperature environment, it can breed a variety of pathogenic bacteria and may also produce a variety of toxins, which cannot be prevented.

　　In a word, coconuts opened in advance have food safety risks. Consumers had better buy the whole coconut directly, and it is safer to ask the clerk or stall owner to open it at that time after buying it. It should be refrigerated immediately after opening, even if it is refrigerated, it is best to eat it on the same day. Eating coconut meat is the same.

　　Why can packaged coconut water be stored at room temperature?

　　100% coconut aquatic products on the market are sterilized and packaged. The bacteria inside have been killed, and the packaging outside is sealed, so microorganisms can’t get in, so it can be safely stored at room temperature for a long time before it is opened.

　　However, once opened, bacteria can enter, which is no longer safe and must be drunk as soon as possible.

　　What should I do if I don’t finish the coconut water in a big package at one time?

　　What if the package of coconut water is too big to drink at one time? Then pour out a part of it and drink it first. The rest of the box should be covered immediately and put back in the refrigerator for refrigeration. Never drink with your mouth to the bottle mouth, which will cause serious bacterial pollution. Even if it is refrigerated, it can’t last long. It is recommended to drink it all within 24 hours.

　　Not only coconut water, but also other liquid foods, such as milk, juice and drinks, need to be refrigerated in time after opening. How long it can be stored in the refrigerator depends on the product characteristics and sterilization process.

　　Generally speaking, products with particularly high acidity have slow microbial proliferation, such as lemon juice, cola, orange juice, etc., and they may not be spoiled or moldy even if they are refrigerated for 48 hours.

　　Those drinks with low acidity should not be refrigerated for more than 24 hours in most cases.

　　Who is suitable for drinking coconut water?

　　Coconut water is not rich in various vitamins, but it is particularly rich in potassium, and the potassium content per 100 grams can be as high as more than 200 mg, while the sodium content is relatively low, with a small amount of calcium and magnesium. At the same time, the sugar content is still relatively low, only 3% to 6%, which is in line with the standard of low-sugar drinks (the sugar content in 100 ml is less than 5 g).

　　Because the osmotic pressure is not high and the sugar content is low, coconut water is a good hydrating drink. For northerners, compared with buying coconuts directly, it is more cost-effective to buy a large box of coconut water at a discount and drink it with the whole family.

　　Because of its high potassium content, low sugar content and low calories, coconut water is more suitable for hyperuricemia and hypertension patients than other fruit juices. Coconut water is also a good thing for people who eat too much salt, or too much meat, lack of fruits and vegetables, and imbalance of potassium and sodium.

　　If you add a little salt and some water, coconut water can also be used as a sports drink. If you drink it directly, because potassium is high and sodium is low, it is not enough to make up for the loss of sodium after sweating a lot.

　　However, people with kidney disease who need to limit potassium can’t drink a lot of coconut water.

　　Coconut water does not have the aroma of coconut meat, but the aroma is in fat. Coconut meat is emulsified and mixed with coconut water, or without coconut water, white water is added directly, and some sugar and emulsifier are added, which is the daily coconut milk.

　　There is no doubt that all milky drinks contain fat. This is true for milk, soy milk, peanut milk, walnut milk, and coconut milk. Milky white is the optical effect after fat emulsification. Therefore, milk-white coconut milk drinks, or coconut milk products used to mix desserts and drinks, have much higher calories than coconut water, and saturated fat accounts for about half of its fat. The aroma and taste are great, but the nutritional value of protein and vitamins is much lower than that of milk and soybean milk.

　　Nowadays, independent brand manufacturers are striving to improve their brand image and product strength. From some models with good reputation and sales in recent years, we can see that the gap between domestic cars and joint venture cars is gradually narrowing, especially in the hot market of SUV, some domestic products have impressed us deeply. Today, we have brought you four representative domestic SUVs of about 100,000 yuan.

　　Guide price: 97,900-153,900 yuan

　　Highlights of the model: completely positive research and development, Chery flagship SUV

　　Chery Tiggo 7 is a heavyweight model launched by Chery in 2016. As the flagship of the Tiggo family, Chery has made great efforts on it. Different from Tiggo 3 and Tiggo 5, Tiggo 7 is launched according to Chery’s "V-shaped forward development system" process, and it is the first model based on Chery’s new platform, which can be described as a great progress of its own brand.

　　In terms of appearance, Tiggo 7 is very recognizable. The front of the car has created a layered shape with several lines, and the concave design of the air intake grille is very innovative.

　　Like the front of the car, the rear part adopts a concave design, which reflects the overall design language. The inverted triangle taillights have a geometric aesthetic feeling.

　　In terms of interiors, the simple and atmospheric style is suitable for all ages. The three steering wheels that run independently in the middle are unique in shape and will not give people a bloated feeling. The brown leather package of the center console and door panel feels good, and the central console hardly uses metal decorative parts, which gives people a just right feeling.

　　The instrument panel adopts the combination of mechanical watch and LCD screen, and the style is very novel. The counter-clockwise tachometer is interesting, but it needs a little adaptation.　　

　　The UI of the multimedia system is well designed, simple and beautiful, with navigation, multimedia, communication and other functions, supporting Carplay, and equipped with Chery Clouddrive in-vehicle interconnection system.　　

　　Tiggo 7 offers two power options: a 2.0L naturally aspirated engine with a maximum horsepower of 122 horsepower and a peak torque of 180 Nm, and a CVT gearbox. The 1.5T turbocharged engine has a maximum horsepower of 152pp and a peak torque of 205nm, which is matched with a 6-speed manual gearbox or a 6-speed dual-clutch gearbox. The driving experience is mainly smooth, and the chassis has a good texture.

　　　 Editor’s comment: Forward research and development is an attempt from scratch. As the former "boss" of its own brand, Chery has the courage to take this step and proved its R&D strength. Although it doesn’t surprise people in design, configuration and power, it is still very competitive in an all-round and balanced way, which can be described as a solid step taken by Chery.

1905 movie network news The first female film "Half the Sky" produced by Jia Zhangke and co-produced by BRICS countries will land in the national cinema on May 10th. The film tells stories about women in five different countries and backgrounds through five short films with different styles and characteristics. It not only redefines women’s strength, but also highlights women’s social and family values. The day before the release, the secrets of the four highlights of the film were revealed to the audience in advance.

　

Aspect 1: BRICS countries cooperate again to present wonderful stories.

The film "Half the Sky" shows the unique folk customs of each country through five short stories. For example, the traditional food "jiaozi" representing China families, the new trend of Russian young people communicating through dating websites and the daily life of traditional Indian families. Among them, actors Wang Luodan and Liu Bei play a mother and daughter in China’s jiaozi, showing the career worries of professional women and the life troubles of housewives one by one.

Aspect 2: Pay attention to the global hot topic "Online dating" and lead a heated discussion.

"Half the Sky" presents the common problems of female groups with five stories with different styles but equally wonderful. The film presents hot topics of global concern in recent years, such as South African female athletes being suspected of their gender, and Russia’s online dating has become a common practice but "seeing death". At the same time, China, Brazil and India all focus on the family, from housewives and professional women to family of origin’s injury and infatuation. Different storylines resonate with different audiences: "South African articles make people feel deeply, and gender can’t restrict us from doing anything. Women can also have strength and willpower beyond men." "When you questioned that women didn’t make money for their families, you didn’t expect that they created value far higher than money."

　

Aspect 3: picturesque, a wonderful trip with multi-cultural integration

The distinctive film styles and pictures in Half the Sky are a highlight. jiaozi is soft and warm, which makes the audience feel at home. "Online Lover" is colorful, and the color matching of the green grass red skirt is passionate and unrestrained, presenting a Russian village like an oil painting version … … The five female directors also incorporated their unique cultural customs into the film, showing the unique social environment and women’s status of each country while the film plot developed, bringing the audience a wonderful international trip.

　

Aspect 4: Assembling international outstanding female directors and focusing on "half the sky"

"Half the Sky" was directed by creative female film directors from China, Russian, Indian, Brazil and South Africa. China director Liu Yulin has been selected for Berlin Film Festival, Busan Film Festival, Taiwan Golden Horse Award and many other domestic and foreign film festivals. The film independently directed by Brazilian director daniela thomas was selected as the grand view unit of the 2017 Berlin Film Festival. The works of Russian director Elizabethan Stishova and South African director Sarah Blanck have been shortlisted for several international film festivals. It is worth mentioning that the Indian short film "Mom’s Holiday" was created by the team, and the director Ashwini Yiye Tiwari was voted as one of the most influential women in India by Indian magazines.

The film "Half the Sky" will land in the national cinema before Mother’s Day on May 10th.

The long-delayed COVID-19 epidemic has once again highlighted the indispensable and extensive influence of digital technology on a global scale. The rise of new technologies such as artificial intelligence, Internet of Things, 3D printing, augmented reality and virtual reality, and quantum computing is subverting the traditional economic and social operation mode and shaping new development opportunities. How a country responds to the various changes brought about by the technological revolution and establishes corresponding competitiveness around digital technology will not only determine its future economic growth, but also affect its geopolitical status. In this context, countries all over the world have put the digital transformation in the fields of economy, governance and life into the important agenda of the government, and increased resource input and policy support to improve their digital competitiveness.

Not long ago, the European Center for Digital Competitiveness of the European Advanced Business School (ESCP) released the Report on the Promotion of Global Digital Competitiveness in 2021 (Digital Riser Report 2021）。 The research report comprehensively uses the relevant data from the World Economic Forum, the World Bank and the International Telecommunication Union to evaluate and rank the current digital competitiveness of 137 countries around the world, and extracts the best practices of countries with rapidly rising digital competitiveness, so as to provide decision-making and action guidance for other countries. The relevant research conclusions have certain reference significance for countries around the world to understand the advantages and disadvantages of their digital transformation from a macro perspective and to calibrate the strategic direction of enhancing digital competitiveness.

The research report simplifies the definition of a country’s "digital competitiveness" as 10 equal weight factors in two categories: "digital ecosystem" and "digital thinking mode", and divides all countries into nine groups, namely, G7, G20 and Asia-Pacific, Eurasia, Europe and North America, Latin America and the Caribbean, Middle East and North Africa, South Asia and sub-Saharan Africa defined by the World Economic Forum. On this basis, combined with the data of the three years from 2019 to 2021, it is scored and ranked. Among them, the elements belonging to the "digital ecosystem" include the difficulty of obtaining venture capital, the cost of starting a business, the time required for starting a business, the convenience of hiring international talents, and the digital skills of university graduates; The "digital thinking mode" includes the digital skills of the working population, the attitude towards entrepreneurial risks, the diversity of labor force, the scale of mobile broadband users, and the acceptance of subversive business development ideas by enterprises. The scoring results intuitively reflect the changes of digital competitiveness of countries in terms of sub-items and overall, while limiting the ranking to nine groups is to ensure that the comparison baseline is relatively fair and the results are comparable. By combing the relevant evaluation results, the report puts forward three main findings:

Nowadays, the global digital competitiveness is changing.

The research report shows that while the digital competitiveness of some countries and regions is rapidly improving, some leading digital countries in public perception are gradually losing their advantages. Taking China and the United States as two digital superpowers, for example, during 2019-2021, China’s digital competitiveness improved obviously (+211), while the United States showed a decline (-72). Moreover, whether in the G7 or G20 group, the ranking of the increase in digital competitiveness of the United States is in a relatively backward position. The analysis believes that the decline of digital competitiveness in the United States is mainly driven by the dimension of digital ecosystem, including a series of adverse effects such as increasing immigration and visa barriers, which makes it more difficult to attract international digital and information professionals. The promotion of China’s competitiveness is mainly reflected in its strong advantages in the dimension of digital thinking mode, including the proposal and deployment of a series of national overall strategic plans, and taking scientific and technological innovation and entrepreneurship as important measures to achieve high-quality development.

In addition to the United States, Britain (-85), Sweden (-92) and other developed countries in digital technology also failed to show a significant increase in digital competitiveness. India (-396), Germany (-176) and other big countries even experienced a sharp decline in competitiveness in both digital ecosystems and digital thinking modes. However, some countries, such as Georgia (+153), Egypt (+258), Canada (+47) and Vietnam (+339), which do not have a high digital starting point, have become the leaders in this field because they have implemented a series of fruitful digital transformation measures. To some extent, this shows that the global digital competitiveness pattern is in the process of dynamic reorganization, and new global digital technology leaders will appear in the future.

Digital competitiveness is closely related to digital transformation measures.

The research report collects the "Best Practice" of digital transformation in G7, G20 and seven regional economic groups whose digital competitiveness has increased significantly in the past three years, covering the actual progress in the fields of strategic planning, policy assistance, investment support and perfect supervision. For example, through the implementation of the "National Innovation and Skills Plan", Canada set up a strategic innovation fund for digital transformation, adding more than 70,000 jobs, driving more than 45 billion US dollars of investment, and injecting new vitality into the national economy; Vietnam pushes the "National Digital Transformation Plan in 2025", vigorously advocates the adoption of emerging digital technologies, builds a digital government, and sets a long-term goal that the digital economy will account for 30% of the national GDP by 2030; Egypt has vigorously promoted the "ICT 2030 Strategy" and the "Digital Egypt" plan, thus becoming the leader of digital transformation in the Middle East. Therefore, the report believes that the promotion of national digital competitiveness is closely related to the government’s clear long-term goal of digital transformation and leading the formulation and implementation of comprehensive planning for digital transformation.

To enhance digital competitiveness, we need to support digital innovation and entrepreneurship.

The research report found that countries with rapidly rising digital competitiveness pay great attention to attracting international talents, promoting innovation and entrepreneurship, and strengthening the education and training of digital skills. For example, Italy has established a legal framework to provide visa convenience and tax incentives for start-up companies and scientific and technological talents through the Entrepreneurship Law (ISA), thus attracting tens of thousands of start-up companies to register and operate in Italy in just three years; The Spanish government has launched a series of entrepreneurship support policies, including the Entrepreneurship Promotion Law, the establishment of a national entrepreneurship office, and the introduction of outstanding international talents. Georgia is actively implementing the "2017-2021 Strategy for the Unification of Education and Science" to promote the modernization of science, technology and innovation system.

In view of this, the research report emphasizes that each country needs to fully develop its own digital thinking mode and digital ecosystem, and pay attention to the speed and effectiveness of policy implementation in order to improve its digital competitiveness. At the same time, from the evaluation results of global digital competitiveness in 2021, under the influence of multiple factors, the speed of digital transformation varies greatly among different countries, and the global competition pattern around digital transformation also shows a rapid change trend, and there may be many possibilities in the future. Generally speaking, countries that attach importance to and vigorously promote digital transformation can basically make significant progress in a relatively short period of time. Even countries with weak digital foundation can realize the acceleration of digital transformation after taking appropriate actions and measures. Therefore, governments should attach great importance to and carefully consider the future strategic decision-making and management mode in this key field, and effectively promote digital transformation based on actual national conditions.

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.

　　　　Biological samples collected from the dead China woman’s body on the "Blagoveshchensk-Moscow" train, as well as laboratory analysis data in the carriage, have arrived in Moscow.

　　　　Onishchenko, director of the Russian Consumer Rights Protection and Public Welfare Supervision Bureau and chief epidemic prevention physician of the Russian Federation, made the above statement on Thursday, according to the Russian new network news.

　　　　He said that the inspection will be conducted simultaneously in two specialized laboratories of the Ministry of Health and one laboratory of the Ministry of National Defense.

　　　　He pointed out that due to the death of a woman in China on the train, the health department started the traditional epidemic prevention emergency mechanism.

　　　　On the morning of April 15th, a 24-year-old Russian woman died unexpectedly while riding a long-distance train from the Russian Far East city of Blagoveshchensk to Moscow. Fifty-one Russian migrant workers and two Russian train attendants were sent to the local infectious disease hospital for isolation observation when the train stopped at the Kirov station. It is reported that the final destination of these China migrant workers is Kaluga.

　　　　This incident has attracted great attention from the Ministry of Foreign Affairs of China. On April 16th, Foreign Ministry spokeswoman Jiang Yu said at a regular press conference that the Ministry of Foreign Affairs attached great importance to the situation that "a Russian woman may have died of pneumonia while taking a train in China".
