　　Xinhua News Agency, Beijing, August 5th Title: 50 yuan, a junior high school composition, has a wonderful business of "writing economy" on the Internet.

　　Xinhua News Agency "China Nets" reporters Yang Siqi and Zhang Duo

　　During the summer vacation, primary and secondary school students’ holiday homework writing business is becoming a hot business, which is launched on major online shopping and social platforms. These schoolwork tasks, which originally belonged to children, have turned into goods that can be delivered online, and have become "cash cows" for "writers", which has aroused the concern of many parents and teachers. The reporter conducted an investigation into this.

　　From a dozen yuan to hundreds of yuan, summer homework business is booming.

　　"Contact customer service consultation — — Inform specific job types — — Determine the price — — Mailing homework — — Pay the required amount — — Start ghostwriting — — I will mail it to you after completion. " A ghostwriting website published such an operation process, and claimed that "professional ghostwriting for primary schools, junior high schools and senior high schools has a correct rate of more than 80%."

　　According to the reporter’s search, many platforms such as Sina Weibo and Baidu Post Bar have summer homework writing business, and the charging standards are different for different types of homework. If you rush to jump the queue, you need to increase the price.

　　Through WeChat, the reporter got in touch with one of the customer service agents who wrote the homework, and asked to write an essay of not less than 500 words on the topic of "I am in the third grade". The other party said that when pricing 50 yuan, 25 yuan’s deposit should be paid first, and the final payment should be paid after the composition is written, and the quantity is large. "Write 3 articles for each 45 yuan and 5 articles for each 40 yuan." The customer service also told reporters that in addition to primary school composition, undergraduate graduation thesis can also be written on behalf of others. The next morning, the customer service sent the written composition to the reporter through WeChat in the form of Word document.

　　An industry insider said that in fact, as early as 2009, such "writing homework" posts appeared in "summer homework bar", and some students posted "kneeling for the answer to summer homework". Nowadays, with the expansion of the ghostwriting business market, its charging standard has also risen, and the average price of completing a workbook has risen from a dozen yuan at first to hundreds of yuan.

　　The reporter found that these websites openly and independently recruit "writers", and some part-time and employment websites also have recruitment information. The "writing economy" has formed a complete industrial chain.

　　At the same time, some college students or high school graduates will also post their own "sideline business" news on social platforms. In the "Shanghai Homework Bar", the landlord "C Little Apple Sauce" said, "The price will go up because of the tight time during the coming school term. I hope everyone will write quickly and don’t miss the cheap opportunity."

　　In order to arouse resonance, many websites have also launched soft articles, such as "My poor summer vacation — — Confessions of a primary school student, etc., through emotional marketing by telling stories. A "professional ghostwriting network" also exposed recent praise records and WeChat transfer payment records.

　　The reporter found that these ghostwriting services can be ghostwritten for daily work except for winter and summer homework.

　　Who gave birth to "ghostwriting economy"?

　　Recently, a parent in Lanzhou City, Gansu Province exposed his son’s summer homework list in the second grade of primary school: "Happy Summer Vacation"; 20 quality diaries; 20 reading records; Practice pen writing; Write and draw once a week; Read extracurricular books every day … …” Some netizens shouted: "This is simply the homework of the second grade of junior high school." "Not only students, but also parents."

　　Yue Long, a professor at Shanghai Normal University, believes that the industrialization and continuous popularity of students’ homework ghostwriting service actually reflects the heavy academic burden of students, and at the same time reveals an impetuous and advanced learning atmosphere.

　　An interviewed junior high school Chinese teacher admitted that some holiday assignments such as "Summer Life" and other workbooks are mostly a mere formality. "Leave homework, children are unwilling to do it; If you don’t stay, parents will worry that parents need to rely on the homework left by the teacher to restrain their children. Only when they see their children writing homework can parents rest assured. " The Chinese teacher said that these holiday assignments are generally not judged, and they will learn to talk about the content of the new semester and have no time to comment on holiday assignments.

　　"This situation provides business opportunities for unscrupulous writers and vendors." John young, a researcher at Shanghai Education Supervision Research Center, said.

　　The reporter’s investigation found that at present, some families tend to respect their children’s "personality" development more and more. In addition, extra-curricular counseling and extra-long interest classes have emerged, and some students no longer "absolutely obey" the school teachers, but arrange their life inside and outside the school more independently. "To write summer homework, it is better to read a good book and make a targeted professional counseling book." A parent said.

　　John young believes that the emergence of the network platform just caters to the change of this educational concept, making writing homework more efficient and convenient, and even some parents "make excuses" for their children, or explicitly or implicitly allow their children to seek homework.

　　Experts call for scientific burden reduction and happy holidays for primary school students

　　John young believes that these ghostwriting businesses not only disturb the educational environment and market order, but also make children feel lazy and lucky, and form the habit of being confused and cheating, which is not conducive to their long-term development.

　　Many netizens believe that ghostwriting business is actually an immoral business practice, turning children’s happy summer vacation into a wonderful business, and relevant departments should correct the unhealthy trend as soon as possible.

　　The interviewed experts believe that finding someone to write homework and find a "gunman" is an act of dishonesty, which will impact and destroy the moral education and value orientation of primary and secondary school students, which is not conducive to their observance of integrity, resulting in a utilitarian understanding and solution to the current predicament. "You can’t confuse the large amount of homework with the purchase of homework to write services. You should tell students that writing homework is a fraudulent act." Xiong Bingqi, vice president of 21st Century Education Research Institute, told reporters.

　　Yue Long pointed out that at present, China’s relevant supervision and legal constraints on the ghostwriting industry are still in a blank state. The education department and relevant market supervision departments should take comprehensive measures to carry out comprehensive rectification, and at the same time increase publicity and guidance, so that ghostwriters, parents and students can form a correct understanding.

　　In view of some "unnecessary" homework, Ding Zhaomin, director of the Education Bureau of nangang district, Harbin, Heilongjiang Province, believes that "reducing the burden" actually puts higher demands on teachers, and its fundamental purpose is to improve the quality of school teaching.

　　John young believes that the ghostwriting market has formed a complete industrial chain at present, which reflects the troubles among parents, students and schools. A more adequate dialogue mechanism should be established among the three to form a joint effort to promote the solution of such educational problems, thus providing a healthier environment for children’s growth.

Officers and men of the Sixth Guangdong Frontier Detachment of the Armed Police stationed on the front line of the Shenzhen-Hong Kong border captured a suspected stowaway from Southeast Asia near the mangrove ecological park in Shenzhen.

According to the China Youth Network, recently, the Sixth Guangdong Frontier Detachment of the Armed Police stationed at the front line of the Shenzhen-Hong Kong border announced that officers and men of the detachment had arrested a suspected stowaway from Southeast Asia near the mangrove ecological park in Shenzhen. It is understood that the suspected stowaway swam from Hong Kong to Shenzhen through the Shenzhen River. On the day of the arrest, the lowest temperature in Shenzhen was 4 degrees Celsius, and the stowaway lurked in the Shenzhen River for six hours. When the border guards found him, the stowaway was covered in mud. Because he had been soaked in water for too long, the suspected stowaway was dying of cold.

"Smugglers choose to sneak in the bad weather environment years ago because they are lucky. They think that border guards and soldiers will relax their vigilance years ago and in bad weather. I don’t know that the worse the environment, the more we demand vigilance. " Ou Zihao, an officer who arrested suspected stowaways, said.

Media-melting viewpoint

Spring Festival movie review!

Listen to the voice of expert film critics

Professor Yin Hong from Tsinghua University:Suspense and comedy, Zhang Yimou’s creation type has been upgraded again, and the multiple reversals of the story are fascinating. Don’t miss any details. Coupled with the top performance of a strong cast, Man Jiang Hong is definitely worth looking forward to.

Film critic:The film "Man Jiang Hong" does not show the sky screaming or strong feelings, but focuses on the sacred moment belonging to ordinary people who are willing to make the right choice for the righteousness in their hearts; Different types of actors compete on the same stage, just to dedicate this film to everyone.

Film critic Shadan:Zhang Yimou +159 Minutes+Comedy Star, when these keywords are put together, the audience will inevitably hesitate. In fact, "Man Jiang Hong" is Zhang Yimou’s ultimate rebellion against his own creative experience. The images in this work completely serve the narrative, or will usher in a double harvest of word of mouth and box office.

Film critic Wu Yanyu:"Man Jiang Hong" is the first shot of director Zhang Yimou’s works to really start the Spring Festival, which is a surprise for the 2023 Spring Festival, and even for the China film market in 2023. It also helps the China film market to officially start the first shot of market recovery.

Cheng Bo, Professor, Doctoral Supervisor and Vice President of Shanghai Film Academy of Shanghai University:The combination of narrative and special effects in Wandering Earth 2, the structure and rhythm of the so-called emotional drama and hardcore drama, although not perfect, are basically compact and effective. Not only that, there are only two films in this series at present, and there should be a third film in the future, such as "the crisis of the sun’s krypton flash". If so, the "Wandering Earth" series will show that China’s ability to incubate its own series of films from contemporary IP has reached a new and even global level. Moreover, in terms of the combination of creativity and craftsmanship, the exploration and interpretation of the theme, and the "going out" of China’s films. In this sense, the hardcore of Wandering Earth 2 is not only in the field of science fiction movies, but also a new milestone of science fiction movies in China.

Film critic Yan Peng:Wandering Earth 2 not only shows the community of human destiny, but also shows the unique feelings of China. The artistic design of the film is excellent, and the special effects are almost flawless, which takes China’s science fiction film to a new height.

Film critic Ji Shaoting:Compared with the first film four years ago, the shooting equipment of Wandering Earth 2 has been upgraded in an all-round way, the crew has accumulated many years of experience, and with the full support of the scientific advisory group, a real China sci-fi blockbuster is worth entering the cinema.

Ge Jing, Associate Professor and Writer of Beijing Film Academy:During the Spring Festival, watching A Bear with Me "Bear Core" is something that many families will do, and both adults and children can find their own fun from it. Dazzling high-tech, exciting scenes, twists and turns and suspenseful storylines make this film the best parent-child viewing choice during the Spring Festival.

Film critic Ma Ning:The series of films "Bears Come and Go" has accompanied us through the 9th Spring Festival today. Movies aimed at the parent-child family market always have a strong box office appeal in the Spring Festival, and even if they are strong, they can have their own place.

Film critic Zhou Guiyi:For 9 consecutive years, the Spring Festival has been accompanied by true feelings. As the China animation IP with the highest emotional stickiness with every child and parent, the series "Bears Come and Go" can bring different surprises every year. This year is to return to the original, return to the theme of family affection, and interpret the true meaning of emotion from the perspective of life science and technology speculation. This year’s Spring Festival file recommends that children and adults with families go to the cinema to watch together. I also hope that this series of animations can stand the test of time and keep a childlike innocence for everyone who has met it.

Dong Wenxin, manager of Jinan Belle Palace Studios:The stable output of the brand has emerged in this year’s Spring Festival file, and "Bear Haunted with Me" Bear Core has once again become the "goalkeeper" of the Spring Festival file.

Ren Shengshu, Associate Professor of Beijing Normal University:Unknown is an unconventional spy film with a familiar routine, but it seems that something is wrong. It is still the "author development" directed by Cheng Er, trying to become the back of a "commercial cool film". Therefore, "Nobody" is inevitably a bit "twisted" by critics and the market, but it still hides the most scarce character in China’s film creation — — The obsession with "aesthetic feeling" of images and the shaping of "three-dimensional" characters.

Dong Wenxin, manager of Jinan Belle Palace Studios:In this year’s Spring Festival, the audience gave artistic works more living space, such as "Nobody", a film that doesn’t look like a "family reunion", and it also gained more than expected box office results.

Yu Xin, Director of China Film Criticism Society and Doctor of Film Studies:Although the current box office performance of Deep Sea is not ideal, it does not mean that it is not a good movie. Whether it is a play or a picture presentation, Deep Sea has a great degree of development and innovation, and it is worth going to the cinema to watch.

Video bloggers say blockbusters in small pieces:Deep Sea is destined to be a work with polarized word of mouth. It has the top-level pictures in domestic animation, and the ink particle special effects that only Chinese people can do, but it also has the most special aesthetics and image style in animated films, which is groundbreaking and adventurous.

Ni Jun, Associate Professor of Central Academy of Drama:Exchange of Life is a movie especially suitable for the Spring Festival, which contains comedy, fantasy, family, love and other elements. If the Spring Festival movie is compared to a big meal, it is undoubtedly a drink that can secrete dopamine and make people happy.

Film critic Min Sijia:The theme of "Teenagers are better than middle age" and "Beginner is better than sophistication" in the film actually has something in common with the previous work. This perspective, like the female creator identity of director and screenwriter Su Lun, is very scarce and worthy of our attention in this special period of the Spring Festival.

Expenditure has been arranged in the departmental budget. Other expenses prohibited by laws and regulations.

　　FAW Group believes that the main reason for the loss is insufficient sales. In the first quarter, FAW Group produced 230,000 vehicles and sold 192,000 vehicles. Among them, the sales volume of FAW-Volkswagen was far below the expected target, with a production of 53,800 vehicles and a sales volume of 30,000 vehicles, with a loss of 300 million yuan. In the sales structure, the increment is mainly low-end products such as Xiali, and the increment does not increase profits. In order to protect the market, the price reduction (or preferential treatment) of some products has exceeded the budget level. In addition, the rising cost of raw materials and the decrease of credit consumption and sales caused by the credit crunch are also the main factors of losses. 　　In addition to the objective factors considered by the enterprise, the key to the loss of FAW Group is whether the sales volume of joint venture products can not go up. The main reason is that the foreign shareholders of the joint venture do not lower the CKD price. China’s automobile market has broad prospects and has become a "battleground" for major automobile companies in the world. Domestic automobile companies must accelerate their independent development in an open competitive environment, and the core of which is to adhere to the open road of independent innovation and realize the localization of key technologies and key components. Only in this way can the healthy development of the domestic automobile market and domestic automobile industry be guaranteed. 　　FAW Group has a special weight in Chinese’s mind, bearing people’s expectations for China’s automobile industry and even the rejuvenation of China. However, the serious shortage of successors has become a bottleneck restricting the development of FAW Group. FAW’s losses are due to management and sales strategy, but the most important thing is that FAW’s brand appeal in the eyes of Chinese people has been seriously weakened. In China, where the competition in the automobile industry is increasingly fierce, the good days of treating several old cars as cash cows are gone forever. In the eyes of Chinese people, FAW has become an elderly person without any vitality.

　　On March 4th, Standing Committee of the Political Bureau of the Communist Party of China Central Committee proposed "accelerating the construction of major projects and infrastructure that have been clearly defined in the national plan, and speeding up the construction progress of new infrastructure such as 5G networks and data centers", and "new infrastructure" became a hot word widely concerned by the society. Industry and capital market show strong interest, expecting "new infrastructure" to become the leader of effectively driving economic development, helping China’s economy get out of the impact of the epidemic and usher in a broader development space. So, where is the new "new infrastructure"? As the "pillar" of China’s economy, how can the central enterprises, which have just fully supported the fight against the epidemic and taken the lead in resuming work and production, play a role in the "new infrastructure"?

　　Central enterprises have acted quickly, starting early, planning early, investing early, developing early and building early, giving full play to the advantages of the main force of the industrial chain, leading the "new infrastructure" with investment-driven and hard-core technology, striving to be investors, developers and builders of the "new infrastructure" industrial chain, upgrading "new consumption" with the "new infrastructure", forming new impetus for growth and promoting high-quality development.

　　Where is the new "new infrastructure"?

　　The concern about "new infrastructure" did not begin this year.

　　In fact, as early as the Central Economic Work Conference held at the end of 2018, 5G infrastructure, UHV, intercity high-speed railway and intercity rail transit, charging piles, big data centers, artificial intelligence, and industrial Internet were identified as "new infrastructure construction".

　　Three months later, at the National People’s Congress in 2019, the government work report clearly requested that "the pace of 5G commercialization and the scale deployment of IPv6 (Internet Protocol Version 6) should be accelerated, and new infrastructure construction and integration applications such as artificial intelligence, industrial Internet and Internet of Things should be strengthened".

　　Infrastructure can be divided into "traditional" and "new".

　　Traditional infrastructure mainly includes railways, highways, airports and bridges. In this field, China is relatively perfect, but there are still shortcomings.

　　New infrastructure is generally considered to include 5G, UHV, intercity high-speed railway and intercity rail transit, new energy vehicle charging piles, big data centers, artificial intelligence, industrial Internet, Internet of Things and other fields. In these areas, China has huge room for development.

　　Different from traditional infrastructure, "new infrastructure" pays more attention to hard-core technologies such as digitalization and intelligence.

　　It is not difficult to find that promoting "new infrastructure" is a clear direction since 2019. At the beginning of this year, under the influence of COVID-19 epidemic and other factors, the "new infrastructure" was put in a more important position, and it became inevitable to accelerate it.

　　As an important basic industry and emerging industry, "new infrastructure" is a new engine for China’s economic growth, which is connected with huge investment and demand at one end and a powerful consumer market that is constantly upgrading at the other. As far as the construction of 5G network is concerned, by cultivating the prosperous Internet economy, artificial intelligence, digital economy and other new technology industries, it will indirectly drive the total economic output of several trillion yuan, laying a solid foundation for seizing the commanding heights of the new generation of information technology in the world.

　　Investment promotion: 5G and UHV construction lead the way, and speed up the "new infrastructure" in a big way.

　　Recently, the three major telecom central enterprises and the Tower Company all said that they will actively accelerate the construction of 5G this year and make greater contributions to the realization of a network power and the comprehensive construction of a well-off society. For a time, 5G became the "leader" of "new infrastructure".

　　According to the "China Mobile Economic Development Report 2020" recently released by GSMA mobile think tank, by 2025, the penetration rate of 5G users in China will increase to nearly 50%, which is equivalent to other major 5G markets such as South Korea, Japan and the United States. China Information and Communication Research Institute predicts that by 2025, the cumulative investment in 5G network construction will reach 1.2 trillion yuan, and 5G network construction will also drive investment in upstream and downstream of the industrial chain and applications in various industries. It is estimated that by 2025, it will drive more than 3.5 trillion yuan of investment.

　　On March 6th, China Mobile started the procurement of the main equipment of the second phase wireless network of 5G this year. The data shows that by the end of February, the number of China Mobile’s 5G base stations has exceeded 80,000, and the number of users of 5G packages has reached 10 million. This year, we will maintain the goal of "building 300,000 5G base stations, and the 5G network will cover cities above the prefecture level".

　　On March 10th, China Telecom and China Unicom issued the "Announcement on Centralized Pre-qualification of Joint Centralized Procurement of Wireless Main Equipment for 5G SA New Construction Project in 2020". According to the announcement, China Telecom and China Unicom will start the joint centralized procurement of 5G SA wireless master equipment, and the estimated procurement scale is not less than 250,000 stations. It is planned to complete all the construction progress before the third quarter. According to another introduction, China Telecom and China Unicom will strive to complete the joint construction task of 47 cities and 100,000 5G base stations in the first half of 2020. Among them, China Unicom plans to achieve 5G coverage of all cities in China by 2020.

　　China Tower said that it will give full play to the advantages of overall planning and fully meet the needs of telecom enterprises for 5G construction economically and efficiently. By the beginning of March, more than 200,000 5G base stations had been built in China Tower. In the construction of 5G, China Tower insists on sharing without new construction, strictly controls the proportion of new stations and reduces the construction cost. More than 97% of the demand is met by using existing resources. At the same time, in-depth cooperation with railways, power grids, real estate, municipal transportation, etc., for the development of 5G, formulate indoor and outdoor standardization and integrated coverage schemes for communication networks.

　　5G is becoming a new infrastructure in our lives, and its future is clearly visible.

　　In fact, the future has come.

　　In this fight against the epidemic, the "black technology" of central enterprises represented by 5G, drones, robots, 3D printing, etc. has made great efforts to help prevent and control the epidemic, and big countries have embarked on the battlefield against the epidemic, winning wide attention and praise at home and abroad.

　　Under the 5G network environment built by China Telecom, China Unicom, China Mobile and other communication companies, in Wuhan, the 5G telemedicine system allows Beijing experts to cross 1,200 kilometers and realize "face-to-face" high-definition treatment guidance with clinicians on the front line of "war and epidemic"; In the shelter hospital, medical staff used wearable devices to connect to the 5G wireless network to collect physiological parameters. China Mobile’s "5G+unmanned epidemic prevention vehicle" intelligent robot is carrying out intelligent disinfection and medical and health services, and working with partners to deploy a medical temperature patrol robot based on 5G communication technology, which comprehensively uses technologies such as the Internet of Things, machine vision, biometrics, artificial intelligence, cloud computing and big data, and integrates various environmental awareness sensors, and can be widely used in stations, squares, business districts, hospitals, schools, communities and key units.

　　Chihiro Location Company, jointly sponsored by Ordnance Industry Group and Alibaba Group, officially launched the "Flying Wing Action" to build a platform for unmanned aerial vehicles to fight epidemics. Tens of thousands of unmanned aerial vehicles across the country are connected to the Beidou high-precision positioning service provided by Chihiro Location, and the drones are used for accurate spraying and disinfection, inspection and shouting and other epidemic prevention operations. China Electric Power Branch and SF Express successfully completed the first unmanned emergency transportation delivery task, and the drone landed at Wuhan Jinyintan Hospital to deliver urgently needed medical and epidemic prevention materials to medical staff.

　　… …

　　Experts from the World Health Organization said that it is simple and efficient for China to conduct online remote diagnosis and treatment by comprehensively using big data, artificial intelligence, 5G and other technologies. The BBC reported that "in the battle against Covid-19, China deployed disinfection robots, smart helmets, drones equipped with thermal cameras and advanced facial recognition software." In the fight against the epidemic, China developed new applications in time, and 5G and information technology played an unexpected role.

　　In this epidemic, big data and information technology of central enterprises helped to prevent and control the epidemic, which played an unexpected role and effect, and provided a powerful reference for epidemic prevention and control and the use of public medical facilities in other countries, and also provided a scientific and technological model for the application of high technology in public health facilities and better treatment of patients in China in the future.

　　UHV, as one of the seven fields of "new infrastructure", shows the main direction of economic and social development and industrial upgrading and revitalization, and has the advantages of long industrial chain, strong driving force and remarkable economic and social benefits.

　　On March 11th, at a video research meeting, State Grid Corporation of China emphasized: give full play to the driving force of UHV industry and accelerate the construction of new infrastructure. According to the latest caliber of the Ministry of Infrastructure of State Grid, the annual investment scale of UHV construction projects of State Grid Corporation is 181.1 billion yuan, which can drive social investment of 360 billion yuan, with an overall scale of 541.1 billion yuan, injecting strong impetus into economic and social development.

　　For example, northern Shaanxi, which started construction on February 28th — The 800 kV HVDC project in Hubei is the first UHV project newly started by State Grid Corporation of China this year, with a total investment of 18.5 billion yuan, which is expected to directly drive the equipment production scale of about 12 billion yuan, drive the investment in power supply and other related industries to exceed 70 billion yuan, and increase more than 40,000 jobs.

　　It can be seen that UHV, as the highlight of "new infrastructure", has long-term competitiveness and is for the future. It is reported that after UHV, State Grid will also accelerate another "new infrastructure" field — — Construction speed of charging piles for new energy vehicles. On March 18th, State Grid proposed to speed up the construction of new infrastructure and make continuous efforts in the development of UHV and the construction of new energy vehicle charging piles. Some experts predict that in the next 10 years, the country is expected to form a charging pile infrastructure construction market of 1.02 trillion yuan.

　　Innovation-driven: big data, rail transit technology research and development, digital upgrading of "new infrastructure"

　　During the epidemic period, China Electric Power Branch quickly set up a big data research team of more than 200 people, and quickly developed and launched a "one network" big data system for epidemic prevention and control and resumption of production. The system adopts big data model of infectious disease dynamics and time series prediction model, and forecasts the confirmed cases in 11 key provinces and 16 key cities in the next ten days from February 6th. The results show that the average prediction error of three days in advance is only 0.81%.　

　　Based on the "One Network" system, China Electric Power Branch has launched a series of mobile phone inquiry applications for the public, including "Little Nurse" who can check people who are in close contact, "Little Housekeeper" who can fill in the basic information of communities and buildings, "Little Warrior" who can check traffic checkpoints, and "Little Helper" who can help enterprises monitor the risk of employees and screen them in time, etc., to meet the new needs of the market in a special period.

　　The docking platform of supply and demand for enterprises’ resumption of work and production developed by State Grid E-commerce has solved the problems of mismatch between supply and demand of materials and asymmetric information in the process of resumption of work and production.

　　"It brings together the supply and demand information of many enterprises across the country. Whether it is purchasing materials in short supply or selling equipment and materials, we can easily find partners, which is really a good helper for our small and medium-sized enterprises to resume work." On March 3rd, Liu Huaping, the general manager of Beijing Shengrui Lianchuang International Trade Co., Ltd., who found the source of meltblown cloth through the supply and demand docking platform of the enterprise built and operated by State Grid E-commerce Company, repeatedly praised it.

　　The supply-demand docking platform for enterprises to resume work and production provides enterprises with services such as release of supply-demand information, display of supply and service information, matching and docking of supply and demand information, and comprehensively assists the production and supply of epidemic prevention protective materials and enterprises to resume work and production. Up to now, the supply and demand docking platform has published more than 6,000 pieces of supply and demand information of more than 5,300 enterprises, with 5.619 million visits to the platform and a cooperation amount of 4.2 billion yuan, which effectively promoted the orderly resumption of work and production of enterprises during the epidemic period and achieved good results.

　　The "supply-demand docking platform" is just a case in which central enterprises use the Internet to "digitize" services for both the supply and demand sides.

　　China Merchants Group has used various new technologies such as blockchain and big data in China Merchants Port to build a unified digital application platform for business innovation scenarios such as paperless and electronic circulation of documents and gate automation, namely China Merchants ePort. During the epidemic period, China Merchants ePort made great efforts to provide 24-hour online customs clearance, logistics and other services for all units and users in the port ecological circle, constantly improving the level of intelligence and automation of operations, greatly reducing offline contact, and building a security line for the business of resuming work and production.

　　The social governance big data platform developed by Aerospace Wisdom Company of the Fifth Academy of Aerospace Science and Technology Group has played an important role in the management and control of many places, from identifying people to identifying vehicles, from personnel flow, information screening of key people to information reporting and integration, and analyzing key difficulties in management and control. China Satcom, a subsidiary of Aerospace Science and Technology Group, also provides users with information about the epidemic situation in novel coronavirus according to the deployment of the State Administration of Radio, Film and Television. More than 140 million rural direct broadcast satellite users in China can receive and check the epidemic situation at any time through the direct broadcast satellite set-top box.

　　The logistics and transportation of hazardous chemicals is the main artery of the whole petrochemical industry. The traditional logistics mode has many disadvantages, such as low level of informatization, high transportation cost, fragmented supervision and potential safety hazards. In order to solve the pain points in the industry, Sinochem Energy Technology has created three products: Canghai Gang, Shipping Gang and 66 Express, providing a complete set of logistics solutions for the petrochemical industry. Through the online connection of shippers, warehouses, fleets, ports and docks, governments, commodity inspection and other related parties, a digital infrastructure of petrochemical supply chain covering warehousing, vehicle and boat transportation will be built.

　　CRRC is vigorously promoting the research and development of intelligent technology applications, which will transform the high-speed rail transit field in the "new infrastructure" to digital manufacturing and innovation-driven transformation.

　　Bogies are one of the most important components on rail transit vehicles, equivalent to the "chassis" of rail transit vehicles, and are the most important components that determine the safety, comfort and reliability of rail transit products. Bogies have more than 2,000 parts and components, which are complex in structure and require high accuracy and quality reliability, directly affecting the running quality of vehicles and the safety of passenger transportation.

　　In March 2019, the world’s first intelligent manufacturing workshop for rail transit bogies built by CRRC Zhuzhou Machinery Co., Ltd. was put into operation, filling the gap in the global application of digital and intelligent technologies for rail transit bogies. The 11 production lines cover the whole process of manufacturing bogies such as processing, assembly, welding, painting and logistics.

　　Zhou Qinghe, Party Secretary and Chairman of CRRC Zhuji Company, said that this model will guide the transformation of the production mode of China’s rail transit equipment manufacturing industry and accelerate the transformation of the whole industry to digital manufacturing and innovation-driven.

　　Driven by the industrial chain: the Internet of Things and cloud computing are in full swing, and the "new infrastructure" is intelligently improved.

　　According to industry experts’ analysis, from the perspective of industrial chain, the UHV industrial chain mentioned above includes power supply, electrical equipment, energy-using equipment, raw materials, etc. The industrial chain is long and interlocking, with strong driving force. The 5G industrial chain mentioned above covers a wider range. The upstream industries mainly include chips, optical devices and radio frequency devices, while the midstream industries mainly include base stations, transmission equipment and base station antennas. Downstream industries mainly include operator market and terminal equipment market, especially the combination of 5G with artificial intelligence, big data and cloud computing, which brings more abundant application scenarios, such as driverless, smart city, Internet of Things and smart medical care, and will bring more convenience to life.

　　Wu Shengyu, director of the Institute of Energy Strategy and Planning of State Grid Energy Research Institute, said that on the one hand, when the epidemic is effectively controlled and after the epidemic, the electricity consumption of the whole society will be replenished, especially in industries and regions that are greatly affected by the epidemic, and the replenishment will be more obvious. On the other hand, other "new infrastructure" fields represented by 5G base stations and big data centers are big power consumers. The resumption of construction of UHV and other infrastructure is to prepare for the power supply guarantee in advance, and further guarantee the "six stabilities".

　　In the workshop of Nanjing Guodian Nanzi Automation Co., Ltd., intelligent logistics cars shuttle between factories to transport materials. A six-axis manipulator is screening the starting voltages of different relays, and it moves quickly. "It used to be the work of four people, but now one manipulator will do it all." The staff said.

　　China huadian’s high-end manufacturing company — — After Guodian Nanzi Smart Factory is fully put into operation, the overall production efficiency will increase by 42.48%, the current human resource cost can be reduced by 32%, the first-time quality pass rate will increase by 13.25%, and the energy consumption will be reduced by 8%.

　　At present, Changqing Oilfield of China Petroleum has built the largest Internet of Things system for oil and gas production in China, covering 94.4% of oil fields, 100% of gas fields and 96% of oil and gas wells, which constitutes the basic data of Changqing Data Lake. Based on this, Changqing Oilfield collects, tracks and coordinates the situation that the daily epidemic situation affects the production in time through the intelligent production command system, and monitors the company’s key production information such as oil and gas production, sales volume, capacity building and production assistance in real time for 24 hours, so as to realize efficient production operation command, intelligent scheduling, information sharing and departmental linkage. At present, the coverage rate of unattended stations in the production line of Changqing Oilfield is over 50%, and the coverage rate of unattended stations in gas fields is 80%.

　　In Dazu, Chongqing, the Intelligent Networked Vehicle Test Base, which is wholly-owned by China Automobile Research Institute, a general technology group, is the largest comprehensive test and evaluation base for intelligent networked vehicles in southwest China. Intelligent signal control system, V2X communication system, intelligent street lamp control system, height-limiting equipment and so on are built in the road area of the base, which can meet the current technical specifications and site test requirements of intelligent networked vehicles and meet the test requirements of all road transport vehicles within 55 tons.

　　Fuzhou Cloud Computing Data Center Phase II civil engineering project undertaken by China Construction Sixth Bureau is in full swing. The project officially resumed on February 20, 2020, with a total construction area of about 36,000 square meters. After the project is completed, it will have 4,092 cabinets, meet the international T3+ and national A-level data center construction standards, and become a national demonstration base for new industrialized industries, becoming the only demonstration base with special series in Jiangxi Province.

　　The National Health Care Big Data Northern Storage Center project located in Jinan is the first national health care big data center construction project initiated in China. The first phase of the project, undertaken by China Construction Fifth Bureau, has a construction area of 44,000 square meters. The construction of the project marks that Jinan has become the first pilot city in China to plan and start the national health care big data construction. The project is aimed at building a world-class and most advanced health care big data center in China. After completion, it will realize an ecosystem of big data industry chain integrating politics, production, learning, research and use.

　　R&D, investment, construction, and more central enterprises are laying out "new infrastructure". As time goes by, central enterprises will perform more and better in the "new infrastructure", better serve high-quality industrialization and high-quality urbanization, promote supply-side structural reform, and serve the high-quality development of China’s economy.

　　Beijing, August 9 (Xie Yiguan) According to data released by the National Bureau of Statistics on the 9th, the consumer price index (CPI) rose by 2.8% year-on-year in July, hitting a new high of nearly 17 months, and the growth rate was in the "2 era" for five consecutive months. Many experts believe that the price increase of pork and fresh fruit is still an important factor for the expansion of CPI. Prices will remain relatively stable in the later period, and CPI may generally level off or slightly decrease in the third quarter.

　　The CPI increase in July continued in the "2 era"

　　In July, the CPI increased by 2.8% year-on-year, with an increase of 0.1 percentage point over the previous month, continuing to be in the "2 era".

　　Dong Yaxiu, director of the Urban Department of the National Bureau of Statistics, analyzed that in food, the price of fresh fruit rose in July, the price of pork continued to rise, and the prices of eggs, chicken, beef, mutton and fresh vegetables also increased to some extent. Among non-food items, the prices of medical care, education, culture, entertainment and housing have increased.

　　On the whole, multiple factors promote the increase of CPI. "According to estimates, in the year-on-year increase of 2.8% in July, the impact of price changes last year was about 1.2 percentage points, and the impact of new price increases was about 1.6 percentage points." Dong Yaxiu said.

　　In July, food prices rose by 9.1%, an increase of 0.8 percentage points over the previous month, which affected the CPI increase by about 1.74 percentage points. Non-food prices rose by 1.3%, down by 0.1 percentage point from the previous month, affecting the CPI increase by about 1.04 percentage points.

　　Fresh fruit and pork push up the overall price.

　　Among the food prices, the prices of pork and fresh fruit have always been a topic of public concern, and it is also an important factor affecting the price increase and change of CPI food.

　　Statistics show that in July, the price of fresh fruit rose by 39.1%, which affected the increase of CPI by about 0.63 percentage points. Pork prices rose by 27.0%, affecting CPI by about 0.59 percentage points.

　　According to the Ministry of Commerce, the average wholesale price of pork in July increased by 8.8% month-on-month and 29.2% year-on-year. The average wholesale price of six kinds of fruits was 8.65 yuan per kilogram, down 2.5% from the previous month and up 45.4% from the same period last year.

　　"The increase in CPI in July has been expanded, largely due to the increase in food prices. At present, the impact of African swine fever on pork prices is difficult to eliminate in the short term. Vegetables and fruits are affected by the increase in seasons, climate, transportation and storage costs, and prices fluctuate greatly." Zhao Xijun, deputy dean of the School of Finance and Finance of China Renmin University, told the reporter.

　　Will the prices of fruits and pork continue to rise?

　　The reporter recently visited many supermarkets in Beijing and found that the prices of some seasonal fruits, such as watermelons and grapes, have dropped, the price of peaches has dropped to around 4-5 yuan, and the price of pork is still firm.

　　According to the information released by the Ministry of Agriculture and Rural Affairs and the Ministry of Commerce, since August, the price of fruit has dropped and the price of pork has continued to rise.

　　Regarding the fruit price trend in the later period, Keke, director of the Department of Market and Economic Information of the Ministry of Agriculture and Rural Affairs, said that with the large number of seasonal fruits coming into the market in summer recently, the total supply in the fruit market is sufficient and the variety is diverse, and the price increase is slowing down, which is expected to enter a seasonal downward trend in the later period.

　　In the face of rising pork prices, Zhao Jinhou, an analyst at Shenwan Hongyuan, believes that from the current high pig prices in the off-season, African swine fever has had a relatively obvious impact on the national production capacity in the past year, and both production areas and sales areas are in a tight state of supply and demand. When the peak consumption season comes in the second half of the year, the price of live pigs may increase significantly.

　　Keke said that due to the increase in the output of poultry meat, eggs, milk and other livestock and poultry products, the adjustment of consumption structure was accelerated, and the quantity of imported pork and its products also increased, the meat market supply was generally guaranteed.

　　What is the price trend in the future?

　　The national agricultural product wholesale market price information system shows that from August 2 to August 8, the price of pork continued to rise, the price of fruit declined, the price of vegetables increased compared with last week, and the price of eggs dropped slightly.

　　According to the macro research report of CICC, looking forward, as the base gradually rises, the upward pressure of CPI will weaken, and CPI may generally level off or decrease slightly in the third quarter.

　　"Affected by uncertain factors such as Sino-US trade friction, the price increase will change," Zhao Xijun told reporters, but overall, prices will remain relatively stable in the later period.

　　3% is the control target of CPI year-on-year average increase. After the increase of 2.8% in July, many people are concerned about whether the price will increase by more than 3%.

　　In this regard, Qin Tai, a senior macro analyst at Shenwan Hongyuan Research Institute, believes that many factors are changing, and it is estimated that the year-on-year average CPI in 2019 will be 2.3%, slightly higher than 0.2 percentage points in 2018.

　　As for whether the monthly CPI increase will exceed 3%, "at present, if the uncertainties can be controlled, this possibility is not great." Zhao Xijun said. (End)

In the history of mathematics, there is a famous problem of "turning a circle into a square".

It was put forward by an ancient Greek philosopher in prison in the 5th century BC. It is about drawing a square with a compass and a scaleless ruler to make its area equal to that of the circle.

However, no one expected that this problem has been puzzling mathematicians for more than 2000 years.

In the end, it was discovered by everyone, and it was impossible to draw it.

The reason is related to π being a transcendental number-

Yes, π is a transcendental number besides the irrational number identity known to primary school students.

When it comes to transcendental number, it’s a really hard concept to understand, and no number of professional textbooks can make it easy to understand.

It can only be said that it is a class of irrational numbers, but it is more "unreasonable" than irrational numbers. .

From the 18th century to the present, back and forth for more than 200 years, a large number of mathematicians from various countries have pounced on it, looking for evidence to prove its existence and ways to judge it.

However, this "little thing" is so elusive that until now there are still many suspected figures that have not been proved and a lot of open problems related to it have not been solved.

"Terrible" is that many mathematicians said:

In fact, I know that it is useless to find out which number is beyond the number, but I just can’t stop!

Therefore, today’s article is a dry issue of mathematics, which comes from the column of Quanta Magazine (author David S. Richeson). It is the most clear and easy-to-understand article that tells the ins and outs of transcendental numbers, and is hereby compiled.

Then, blessed are those who like mathematics today-

Love beyond a few times again, and see how it was discovered by mathematicians and how it was related to that Millennium problem.

The Unsolvable Problem of "Turning a Circle into a Square"

Mathematician Leopold Kronecker famously said:

God himself created natural numbers, and the rest came from human power.

Nowadays, although all kinds of numbers have a fascinating and complicated history, basically everyone has a clear definition of them.

For example, integers are positive integers and zero plus negative integers. Rational number is a number that can be expressed as the ratio of two integers, including integers, finite decimals and infinite cyclic decimals.

If the decimal places of this ratio are never divided and never repeated, it is an irrational number.

Then rational numbers and irrational numbers together form real numbers, and real numbers and imaginary numbers form complex numbers.

Among them, today, we all agree that rational numbers were discovered by hippasus, who lived around the 5th century BC (and he died because of it).

But in fact, his discovery belongs to geometric meaning rather than arithmetic.

He proved that you can find two line segments that cannot be divided into several equal lengths, such as the sides and diagonals of a square.

Today we call this incommensurability, which means that their lengths are not rational multiples of each other.

Therefore, the diagonal length of a square is √2 times the side length, and this √2 is called an irrational number.

Undoubtedly, using compasses and straightedge, we can draw a line segment with any positive rational length.

However, some unreasonable lengths are also acceptable. For example, in the famous golden ratio (1+√5)/2, draw a regular Pentagon with a side length of 1 and take its diagonal.

In 1637, the famous mathematician Descartes proved:

As long as a number can be represented by integer operations of addition, subtraction, multiplication, division and square root, then we can draw the corresponding line segments (such as all positive rational numbers, as well as the √2 and the golden ratio just mentioned).

Therefore, if we can express π with an exact formula, can we solve the problem of "turning a circle into a square"!

The problem is, I can’t find it.

In a blink of an eye, 200 years have passed (two centuries have passed).

A French mathematician named Pierre Wantzel finally proved:

If a number can be drawn by line segments, that is, it can be constructed, then it must also be the root of a polynomial that cannot be further factorized or simplified, and the degree of the highest term of this polynomial is a power of 2 (such as 2, 4, 8, 16, etc.).

For example:

√2 is the root of the polynomial x2–2, and the golden ratio is the root of x2–x–1, so they can all be drawn.

And like 3; √2 is the root of the polynomial x3–2, which does not meet the condition of the second power, so it is impossible to draw a line segment of this length.

However, even if we know this law, we still haven’t found the exact expression of π, and the problem of turning a circle into a square is still unresolved.

It was finally proved that it could not be drawn at all.

In fact, the key to solving the problem of turning a circle into a square is just like mathematicians divided real numbers into rational numbers and irrational numbers before-complex numbers need to be divided into two sets.

For complex numbers, many of them are equal to the roots of polynomials with integral coefficients, which mathematicians call algebraic numbers.

Every rational number is an algebraic number, and so are some irrational numbers, such as 3; √2, and even the imaginary number I, it counts, because it is the root of x2+1.

Not all complex numbers are like this, so the values that do not belong to this category are called transcendental numbers.

However, it is not obvious whether a transcendental number exists, and it is also very challenging to prove whether a given number is transcendental, because it is necessary to disprove that a number is not the root of any integer coefficient polynomial.

The first breakthrough point was born in 1844, and a French mathematician named joseph liouville thought of such an indirect method:

Since irrational numbers can’t be well approximated by rational numbers, if I find a number that can be infinitely approximated by fractions with smaller denominators, it must be something else: transcendental numbers.

So, Joseph Liouville constructed such a number:

L=0.1100010000000000000000010…

It has only 0 and 1, where the position of 1 appears in turn by "n!" Decide that the position of the first 1 is equal to "1!" , that is, 1, and the second is equal to "2!" , appears in the second place, and the third is equal to "3!" , in the sixth place, and so on.

This ingenious design makes the scores of 1/10, 11/100 and 110001/1000000 very close to the value of L itself.

This proves the existence of transcendental numbers (that is, he created this L).

However, the number π does not satisfy Joseph Liouville’s condition (it cannot be infinitely approximated by rational numbers), so it is not clear whether π is beyond the number.

The important breakthrough came in 1873, nearly 30 years later.

A French mathematician named Charles Hermite designed a clever method to prove that the base e of natural logarithm is transcendental.

This is the first transcendental number that is not artificially designed, which makes Lin Deman, a German mathematician, finally prove that π is a transcendental number on the basis of his theory nine years later.

First, he proved that as long as D is a nonzero algebraic number, ed is a transcendental number.

In other words, if ed is an algebraic number, but d is either 0 or transcendental.

In this case, based on Euler’s identity, which is recognized as the most perfect formula in mathematics, eπ i = 1, the category of π can be deduced.

Because -1 is an algebraic number, πi must be a transcendental number based on the theorem just now, and π must be transcendental because I is also an algebraic number.

In this way, "big things are not good"-

π is a transcendental number, which means π does not meet the definition of "line segment that can be drawn" mentioned in the previous paragraph, so the problem of turning a circle into a square put forward by ancient Greek philosophers thousands of years ago is impossible to realize.

The story is not over yet.

The story of turning a circle into a square is over, but the exploration of transcendental numbers has just begun.

Shortly after E was proved to be a transcendental number, another mathematician proved that infinite numbers actually have different sizes, but the infinity of rational numbers is the same as the infinity of integers. Such a set is called "countably infinite".

However, the set of real numbers and irrational numbers is larger, which is uncountable infinity; At the same time, although the algebraic number set contains all rational numbers and infinitely many irrational numbers, it is still an infinitely small and countable infinite set.

Therefore, its complement, that is, transcendental number, is uncountable and infinite.

In other words, most real numbers and complex numbers are transcendental numbers.

-Although there are so many excesses, by the turn of the 20th century, mathematicians could only identify a few of them.

In 1900, the famous German mathematician David Hilbert listed a famous list of 23 most important unsolved mathematical problems, the seventh of which was:

It is proved that when A is an algebraic number and is not equal to 0 or 1, and B is an algebraic irrational number, ab is a transcendental number.

In 1929, Aleksandr Gelfond, a young Russian mathematician, proved that B = I √ r and r are special cases of positive rational numbers, which means that eπ is a transcendental number.

This result is surprising, because according to the theorem, e and π are not algebraic numbers.

However, by manipulating Euler’s identity skillfully again, we know what’s going on:

Soon after, another mathematician discovered that 2√2 was a transcendental number. Then, the seventh problem listed by David Hilbert was solved by two mathematicians independently.

Later, Alan Baker, a mathematician, published a series of articles, summarizing the achievements of these people, which made us have a deeper understanding of transcendental numbers, and therefore won the Fields Prize in 1970.

Of course, at the age of 31, his greatest achievement in winning this honor is to prove that two values such as the following are also transcendental numbers:

Until now, there are many open questions about transcendental numbers, and there are many concrete numbers that seem to be "very transcendental", which have never been proved, such as "eπ", "e+π", "ee", "π π" and "π e".

But as said at the beginning, the mathematician said:

It may not be useful to know who is above the number, but if we have the ability to know but choose not to know, it is definitely unacceptable.

Seriously respect.
