　　Recently, the Ministry of Agriculture and Rural Affairs and the Central Network Information Office jointly issued the "Digital Agriculture and Rural Development Plan (2019-2025)" to make top-level design and systematic planning for promoting the development of digital agriculture and rural areas. To fully implement the deployment requirements of the plan, it is necessary to strengthen scientific and technological innovation in digital agriculture and rural areas and create new engines and kinetic energy for agricultural and rural modernization.

　　The integration of digital technology and agriculture and rural areas is accelerating, but the development of digital agriculture and rural areas still faces many challenges.The new generation of information technology, represented by mobile Internet, big data, cloud computing and artificial intelligence, is developing with each passing day. The data is exploding and growing, gathering in large quantities, and digitalization, networking and intelligence are accelerating to penetrate into the agricultural industrial system, production system and management system, profoundly changing the global economic landscape. The CPC Central Committee and the State Council vigorously promoted the construction of digital China, implemented the strategy of digital countryside, continuously improved the ability of scientific and technological innovation, significantly accelerated the research and development of facilities and equipment, vigorously developed remote sensing, Internet of Things and big data applications, synchronized development of digital industrialization and industrial digitalization, and the emergence of new digital industries and formats, which promoted the digital transformation and upgrading of traditional agriculture and rural areas. Compared with industry and service industry, the application of digital research in agriculture and rural areas is obviously lagging behind. The infrastructure is still weak, the construction of data resource system is not perfect, and the lack of standards hinders the application collaboration and develops the foundation "gap"; The research and development strength of core key technologies is insufficient, the adaptability of agricultural robots and intelligent agricultural machinery equipment is poor, and the innovation ability is "out of gear"; The integration of digital technology with agriculture and rural areas is insufficient, data integration is insufficient, development and application are insufficient, and the level of industrialization is "broken", so it is urgent to fill the "short board" of insufficient digitalization.

　　Promote scientific and technological innovation in digital agriculture and rural areas and empower agricultural and rural modernization with data.We should take "data-knowledge-decision-making" as the main line, break through the core key technologies, equipment and integrated systems, and lay a solid foundation for the development of digital agriculture and rural areas. First, strengthen the innovation of accurate perception and data collection technology, build an agricultural and rural information collection technology system integrating "sky and land", carry out research on data collection, input, summary, application and management technology, improve the ability of obtaining and processing raw data, and solve the basic problem of "where does the data come from and how to manage it". The key point is to promote the research and development of professional remote sensing satellites to meet the needs of agriculture and rural areas, break through the common key technologies of UAV agricultural application, overcome the special sensors for agricultural production environment and physiological signs of animals and plants, and realize cross-regional, all-factor and multi-level data collection of agricultural resources and environment, production, management, management and service in important agricultural areas and pastoral areas; Research and develop a big data management platform for agriculture and rural areas, and break through key technologies such as "centralized+distributed" integrated cloud architecture and data security for agricultural and rural resources and assets. The second is to strengthen the innovation of data mining and intelligent diagnosis technology, build an intelligent processing and analysis technology system for agricultural big data, strengthen the advanced layout of strategic cutting-edge technologies such as artificial intelligence, virtual reality, blockchain+agriculture, and big data cognitive analysis, and solve the key problem of "how to process and analyze data". The key point is to tackle key problems in common, integrate agronomy knowledge and models, computer vision, deep learning and other methods, and develop proprietary models and algorithms for monitoring, identifying, diagnosing, simulating and regulating animal and plant production, so as to realize digital and intelligent diagnosis of all factors and the whole process of agricultural production;Focusing on rural digital services, we will strengthen the research and development of key technologies such as agricultural and rural data resource association mining, intelligent retrieval, intelligent matching and deep learning to meet farmers’ all-round information needs for public welfare services, convenience services, e-commerce and experience services. The third is to strengthen the technical innovation of precise management and information service, build a technical system of intelligent decision-making and management in agriculture and rural areas with data empowerment, speed up the digital transformation of industry management and service processes, and solve the export problem of "how data serves". The key point is to strengthen the integration research of agricultural and rural proprietary software and information system, and develop ambient intelligence control system, rapid detection of agricultural product quality and cold chain logistics technology, and reliable traceability technology of agricultural products; Strengthen the independent research and development capabilities of intelligent equipment, create a number of agricultural intelligent sensing, intelligent control, autonomous operation and other material equipment, and focus on breaking through intelligent equipment such as agricultural robots, numerical control spraying, intelligent detection, intelligent handling, intelligent picking, and grading and sorting of fruit and vegetable products; Develop digital agricultural standards and specifications, and establish data standards, data access and services, software and hardware interfaces and other standards and specifications.

　　Construct the scientific and technological innovation system of digital agriculture and rural areas, and enhance the independent innovation ability of digital agriculture and rural areas.To accelerate the scientific and technological innovation of digital agriculture in rural areas, we should not only play the role of the government, but also mobilize the forces of all parties to form a joint force and jointly promote it. It is suggested that government departments at all levels should further increase investment, improve special facilities and R&D bases, and build a number of national digital agricultural rural innovation centers and professional sub-centers around strategic frontier technology layout, key common technology research, technology integration application and demonstration, and agricultural artificial intelligence R&D application, and build an innovation platform for technology research, equipment research and development and system integration. Take tackling key problems in digital agriculture and rural science and technology as the support focus of major national special projects and key research and development plans, establish a modern agricultural industrial technology system, and promote the deep integration of digital technology and agriculture and rural areas. Cooperate with scientific research institutions, universities, enterprises and other parties to cultivate a number of leading talents, engineers and high-level management teams in digital agriculture and rural areas. Strengthen the training of digital agriculture and rural business, carry out the activities of talents going to the countryside in the field of digital agriculture and rural areas, popularize the relevant knowledge of digital agriculture and rural areas, and improve the application and management level of digital technology for "three rural" cadres, new business entities and high-quality farmers. As a national comprehensive agricultural research institution, China Academy of Agricultural Sciences will gather the research strength and scientific and technological resources of the whole hospital and even the whole country, aim at the strategic needs of China’s digital agriculture and rural development, condense major scientific and technological propositions, and carry out collaborative innovation and joint research on major theories, key technologies and equipment of digital agriculture and rural agriculture from a higher level and a broader perspective to solve major scientific and technological problems;Focusing on the deep integration of digital technology and agricultural and rural modernization, we will effectively integrate existing advanced equipment, practical mature technologies and system achievements, carry out standardized assembly, integration, maturation and application verification, accelerate the transformation and demonstration application of digital agricultural and rural scientific research achievements, and explore the two-way integration mechanism of "innovation chain+industrial chain" to provide strong scientific and technological support for implementing rural revitalization strategy and solving China’s "three rural" problems.

Experienced the epidemic in 2020, for any film and television company, it has experienced unprecedented difficulties.

After half a year’s closure, domestic cinemas ushered in a season of recovery, but the performance of the domestic film market, which has entered the Lunar New Year file cycle, is still tepid, and the daily box office remains at around 30 million.

Recently, the third quarter financial reports of 20 listed film and television companies have been disclosed. There were as many as 15 film and television companies that lost money in the first three quarters, of which WANDA CINEMAS lost as much as 2.015 billion, ranking first, while Huace Film and Television, which focuses on TV drama business, made a profit of 203 million yuan.

The fourth quarter and the Lunar New Year file are not only the last hope for companies to turn over their performance, but also the future and destiny of many film and television companies. If they lose money for two consecutive years, WANDA CINEMAS will be "ST" and Huayi Brothers will also face the risk of being delisted.

At this important schedule node, we don’t need to be "calm", but we are more eager to be "crowded".

According to the third quarterly report, WANDA CINEMAS achieved an operating income of 3.214 billion yuan and a net profit loss of 2.015 billion yuan in the first three quarters.

As WANDA CINEMAS suffered a huge loss of 4.729 billion yuan last year, it will be specially treated as a "ST share" according to the provisions of the Shenzhen Stock Exchange that "the net profit has been negative for two consecutive years". If Wanda can’t work miracles in the fourth quarter of this year, it may become a "ST WANDA CINEMAS".

At the critical moment, on the evening of November 9, WANDA CINEMAS released the Report on the Issuance of Non-public Offering of A Shares and the Listing Announcement, announcing that the total amount of funds raised reached 2.93 billion yuan, which was the first company in the film and television industry to complete the fixed increase this year and the largest fixed increase project in the history of A-share film and television industry.

The lock-up period of this fixed increase is 6 months, and Wanda will be used to build new cinemas, replenish the company’s working capital and repay funds. Affected by this news, it opened in the morning of November 10th, and WANDA CINEMAS once had a daily limit.

This year’s WANDA CINEMAS is a bad year, with few bright spots in the market business. The overseas cinema industry laid out many years ago has now become a huge drag.

In 2012, Wanda Group invested $2.6 billion to acquire 100% equity of AMC Entertainment, and WANDA CINEMAS became the largest cinema line operator in the world.

After many years, Wanda continued to adhere to the business philosophy of "Buy in buy buy". After successively acquiring cinemas such as Odeon, UCI and armike, AMC also became the largest cinema company in the United States.

When the epidemic struck, AMC’s once proud scale advantage suddenly became the company’s huge weakness.

At the beginning of this year, AMC announced the closure of 1,000 cinemas. Since then, it has fired a number of employees and launched a salary reduction plan for cinema executives. Even so, AMC has recently reported that funds are in a hurry. Some Wall Street analysts said that the bankruptcy of AMC is almost a foregone conclusion.

The situation in the American market is in dire straits, and domestic business is also difficult to do. Wanda currently has more than 600 cinemas in China. During the closure of the epidemic, the fixed costs of Wanda Studios such as depreciation, rent, employee compensation and financial expenses were high, which made its revenue performance suffer a great impact.

At the same time, in the film and television business sector, Wanda has not achieved outstanding results. Although there is a film jointly produced by The Sacrifice and WANDA CINEMAS, it is a drop in the bucket for WANDA CINEMAS, which suffered huge losses, given that the film has not reached the box office volume of 1 billion at present.

With Detective Chinatown 3’s announcement of the Spring Festival in 2021, it is almost announced that WANDA CINEMAS has completely abandoned this year’s film market.

In September, Wanda Film and Television Group released the annual film list for 2021-2022, and released more than 40 new film and television projects, such as Get My Brother Away 2, Searching for Dragons 2, Ghost Blowing the Lantern, Miskilling 2 and Seeing You, by Detective Chinatown 3 in one breath.

Wanda’s film and television business is betting on the next two years. This year’s Lunar New Year file has been abandoned. WANDA CINEMAS announced that its business will return to normal in the fourth quarter, but Wanda’s return to blood will be very limited in the case of a depressed market.

On August 21st, it was just one month since the cinema officially resumed work.

The Eight Hundred, which announced its withdrawal last year, was officially released on this day. In one fell swoop, the film broke the gloomy atmosphere of the market for a long time. At that time, under the condition of limiting the attendance rate by 30%, it eventually accumulated more than 3.1 billion and became the global box office champion in 2020.

The Eight Hundred not only boosted the confidence of the whole film market, but also gave Huayi Brothers in from the mire a shot in the arm.

As the first stock of film and television on the Growth Enterprise Market, Huayi Brothers lost 1.09 billion yuan and 3.96 billion yuan respectively in the past two years. If losses occur for three consecutive years, Huayi will also face the risk of delisting.

The crux of Huayi is not the continuous loss, but the lack of hope. After "Mobile Phone 2" and The Eight Hundred successively announced the withdrawal of files, Huayi’s hands are running out of cards. Tsui Hark’s "Four Kings of Di Renjie" was cold at the box office, while Xiaogang Feng’s Only Cloud Knows’s performance was mediocre, and the trump card was exhausted, but it still didn’t work, which made Huayi, who had been in the scenery, helpless and gradually marginalized.

Huayi Brothers’ third quarterly report shows that the company achieved operating income of 1.107 billion yuan, down 31.51% year-on-year, and net profit loss of 326 million yuan. It is worth mentioning that in the third quarter, Huayi achieved an operating income of 783 million yuan, up 45.02% year-on-year, which was mainly due to the nearly 600 million yuan of revenue from The Eight Hundred.

But at the same time, Huayi Brothers still suffered a loss of 94.563 million yuan in the third quarter, which was mainly affected by the non-recurring investment loss confirmed by the equity disposal of overseas joint venture company Brothers International LLC.

Looking at the performance in the first three quarters, Huayi’s main support point is still the film and television business, with revenue accounting for 89.88%. Brand authorization and live entertainment, which had made a high-profile March before, accounted for only 4.92%, and Internet entertainment accounted for 4.59%. However, in terms of film and television business, Huayi’s online dramas, such as Beggar with Nine Fingers, Kitchen with Fireworks, and Looking for Porcelain from Antique close encounter of mahjong, were all mediocre, which failed to cause market waves.

Obviously, there is only one The Eight Hundred, which can’t save Huayi, who is deeply mired in the mire.

Huayi also participated in the movie The Sacrifice, which, like Wanda, can bring very limited revenue. The Order to Serve the Gods produced by Huayi has been announced as the file for the Spring Festival in 2021. Since then, Lu Chuan’s "749 Bureau", Stephen Chow’s "Mermaid 2" and Xiaogang Feng’s "One Year in Spring" are all key projects of Huayi, and they can’t be missed.

In the past month, the share price of Light Media dropped from the highest of 16.66 yuan to 11.81 yuan, and its market value evaporated by about 14 billion yuan.

The data shows that the operating income of Light Media in the first three quarters was 481 million yuan, down 80.46% year-on-year; The net profit of returning to the mother was 63.7202 million yuan, down 94.26% year-on-year.

In the first three quarters of this year, the R&D expenses of Light Media increased by 61.16% compared with the same period of last year, and most of these funds were used in the animation production business of the company.

In 2015, Light established the striped house film industry, which specializes in the production of animated films. Ne Zha is the work that striped house has been pregnant for four years. The amazing box office of the film of 5.035 billion yuan made Light taste the sweetness for the first time, and it is reasonable for Light to continue to increase its animation business.

In 2012, "Sorry" made Light Media famous in World War I, and after many years of layout, Light finally ushered in a big explosion again, that is, the animated film Ne Zha released last summer.

As the box office in Ne Zha rises, the stock of Light Media also rises accordingly, even surpassing WANDA CINEMAS for a time, becoming the leader of film and television stocks. Until this year, the epidemic caused almost all major film companies to stop eating, but Light also made a small profit by developing derivatives of Nezha.

Because there are no heavy assets such as cinemas and cinemas, the light media, which travels lightly, can still make a small profit, although its revenue has fallen sharply. Ray’s revenue mainly comes from the movie Sheep Without A Shepherd, the derivative development of the movie Ne Zha in the first half of the year, and The Eight Hundred’s Buckwheat Grows Wild and My Girlfriend is a Robot, etc., which are all released by Ray’s participation or agency.

At the same time, the revenue of Legend of Deification, whose National Day box office exceeded 1.5 billion yuan, has not been included in the first three quarters, but according to the current market performance of Legend of Deification, the revenue that this film can bring to the light is about 400 million yuan.

At the end of Legend of Deification’s film, the light also released the eggs of the next film "Deep Sea". In addition, animated films such as "Big Fish Begonia 2" and "Journey to the West" are also ready to meet the audience.

In the three quarterly reports of film and television companies, Huace Film and Television has the most outstanding performance.

In the first three quarters, Huace achieved a total revenue of 1.894 billion yuan, up 44.60% year-on-year, and the net profit attributable to shareholders of listed companies was 203 million yuan, up 736.72% year-on-year.

As an old film and television company, Huace’s annual drama output ranks first in film and television companies for many years, and there are often explosions.

This year’s Huace has a costume romance drama "Beautiful South Song", an urban workplace drama "Ordinary Glory", and "In the Name of Family" with the theme of healing youth growth, with diverse types and good market response.

In terms of reserved projects to be broadcast, many plays, including "8090", "Dear, Beloved", "You are my city camp", "Mirror Twin Cities" and The Legend of Fei, have entered various platforms and TV programs.

In terms of movies, Huace film and television also has an important layout, not only participated in the recent popular movie The Sacrifice, but also the movie A Writer’s Odyssey, which is mainly directed by Huace, will be released in the Spring Festival next year.

In the context of the huge impact on the film market, Huace Film and Television, the main drama series, went upstream and handed over a stable answer sheet. Although this is not surprising, it is also a rare surprise.

After a huge loss of 2.306 billion yuan in 2019, Beijing culture was hit again in the first three quarters of 2020, and various businesses fell across the board.

The financial report shows that in the first three quarters of 2020, Beijing Culture realized an operating income of only RMB 13 million, a year-on-year decrease of 98.15%, and a net profit loss of RMB 117 million. At the same time of the decline in performance, the capital chain of Beijing Culture also tightened. The company’s asset-liability ratio rose from 24.22% in 2018 to 52.81% in the third quarter of this year.

Up to now, My People My Homeland, a film controlled by Beijing culture, has closed at the box office of 2.762 billion yuan, which is expected to turn the final performance of Beijing culture into a profit.

On the unilateral side of the film to be screened, Bath Buddy produced by Beiwen has announced the final file on December 11th, "Hello! Li Huanying is scheduled for the Spring Festival in 2021, and the series "Fengshen", with a total investment of nearly 3 billion, will also officially meet the audience next year.

Backed by the powerful background resources of Hunan Radio and Television, Mango Hypermedia often staged the magical drama of "making small and big".

According to the financial report, Mango Supermedia achieved operating income of 9.471 billion yuan in the first three quarters, up 15.05% year-on-year, and net profit attributable to shareholders of listed companies was 1.612 billion yuan, up 65.39% year-on-year.

The biggest advantage of mango hypermedia, which focuses on self-made content, lies in low-cost investment. No matter whether it is drama series or variety show, it can always harvest unexpected surprises. This year’s fire variety "Sister Riding the Wind and Waves" has helped the stock of Mango Hypermedia to soar to a new level with a market value of hundreds of billions. The next stop is happiness, in the name of my family, dear myself, glass and other dramas are also hot works with high topics, which has greatly increased the revenue of Mango TV.

Since then, Mango has also released a brand-new "Monsoon Plan" short theater in terms of incubating potential variety shows such as "Sister Braving the Wind and Waves 2" and "Brother with Thorns", and plans to build a total of ten short plays with 12 episodes per season.

In the first three quarters of 2020, Wentou Holdings achieved a revenue of 282 million yuan, a decrease of 80.64% compared with the same period of last year. The net loss attributable to shareholders of listed companies was 788 million yuan, and the net profit decreased by 1,860.57% year-on-year.

Wentou Holdings said in the third quarterly report that the company’s operating income in the first three quarters decreased by 80.64% year-on-year, mainly due to the impact of the COVID-19 epidemic, the cinema was suspended from late January to mid-July, resulting in a significant decrease in revenue during the reporting period compared with the same period last year.

By September 30, 2020, Hengdian film and television had a total of 70,300 screens in China. In the first three quarters, the total box office of China film market was 7.563 billion yuan, a decrease of 84.20% compared with the same period of last year, which made Hengdian film and television revenue drop sharply.

After the cinema resumed work, Hengdian Film and Television continued to increase the layout of the cinema industry. In the third quarter, 16 new cinemas were opened and 102 new screens were added. In the first three quarters of this year, Hengdian Film and Television achieved an operating income of 399 million yuan, a year-on-year decrease of 81.27%, and a net loss attributable to shareholders of listed companies was 368 million yuan.

Jinyi Film and Television, which also specializes in cinema, also suffered a decline in performance. In the first three quarters of 2020, its revenue was about 220 million yuan, down 85.90% year-on-year. The net loss was about 406 million yuan, a year-on-year decrease of 487.33%.

In the first three quarters, Ciwen Media’s main revenue items included Trident, Thunder in the Restarted Sea, Chance of Winning and The Voice of Chinese Dreams Our Songs. Due to poor market performance, its revenue dropped sharply.

Ciwen Media achieved operating income of 338 million yuan in the first three quarters, down 60.28% year-on-year. The net profit attributable to shareholders of listed companies was 18.2825 million yuan, compared with 89.8912 million yuan in the same period last year.

In the first three quarters, Hualu Baina achieved an operating income of 73.633 million yuan, a year-on-year decrease of 84.53%, and the net profit attributable to shareholders of listed companies was 35.0971 million yuan, a year-on-year decrease of 61.53%.

Regarding the reason for the decrease in operating income compared with the previous period, Hualu Baina said that it was mainly due to the delay in the project progress during the reporting period and the decrease in repertoire income compared with the same period of last year.

Huanrui Century’s revenue in the first three quarters of 2020 was only 17.19 million yuan, a year-on-year decrease of 87.49%; The net loss was about 148 million yuan, a year-on-year decrease of 2716.26%.

Huanrui Century said that the decrease in revenue was mainly due to the decrease in drama series of some broadcast projects and the impact of the project cycle. The company’s film and television drama sales revenue and artist brokerage income decreased significantly compared with the same period of last year.

In 2018, it lost 927 million yuan, and in 2019, it lost 1.007 billion yuan. If it can’t make a profit for three consecutive years, Tang De Film and Television will be in danger of being directly delisted. Nowadays, Tang De film and television, which is dragged down by Ba Qing Chuan, is exhausted. In the first three quarters, the operating income was 170 million yuan, and the net loss attributable to shareholders of listed companies was 83.7 million yuan.

In the first three quarters, Happiness Blue Sea Cucumber invested in works such as Stewed Sydney with Rock Sugar, Trident, Children in the Bay Area and Happiness Will Knock on the Door, but it is difficult to have a decisive impact on the company’s revenue. In the first three quarters of 2020, Happiness Blue Ocean realized a total operating income of 217 million yuan, a year-on-year decrease of 84.5%, and the net profit attributable to shareholders of listed companies was a loss of 275 million yuan, a year-on-year decrease of 673.66%.

Since the cinema officially resumed work, the film and television market has shown obvious signs of recovery, and explosive works have appeared from big screen to small screen. As the first important financial report after the cinema resumed work, the third quarterly report of the film and television company has a very important weathervane significance for the current market performance and future trend.

Judging from the overall financial report, film and television companies are basically in the post-traumatic recovery period. If film and television companies in the post-cold winter era want to get back on track, it is essential to continuously output high-quality works. Whether it is to boost theater attendance or create topics to boost revenue, the principle of "content is king" will not change.

If winter comes, can spring be far behind? After the most difficult period, the next performance of the film and television market is worth looking forward to.

On August 31st, the Federation of Industry and Commerce (General Chamber of Commerce) of Jincheng Economic and Technological Development Zone was established and the first member representative meeting was held ceremoniously. 90 representatives attended the meeting. Liang Rong, Vice Chairman of Provincial Federation of Industry and Commerce, Secretary of Political and Legal Committee of Jincheng Municipal Committee, Shi Yunfeng of United Front Work Department, Fan Zhaosen of Standing Committee of Jincheng Municipal Committee, Secretary of Party Working Committee of Development Zone, Director of Management Committee, Wang Zhiqiang, Executive Vice Minister of United Front Work Department of Municipal Committee, Li Lingzhi, Vice Minister of United Front Work Department of Municipal Committee, Party Secretary of Federation of Industry and Commerce, and Cheng Gangqiang, Chairman of Municipal Federation of Industry and Commerce attended.

In his speech, Cheng Gangqiang demanded that the convening of the meeting marked that Jincheng took the lead in completing the organization and establishment of the Federation of Industry and Commerce in eleven cities and five national development zones in the province. In the new era and new mission, the development zone Federation of Industry and Commerce should strengthen its own construction and integrate the purpose of "building the meeting politically, uniting the meeting, serving the meeting and strengthening the meeting through reform" into its daily work; We should do a good job in building the membership team and improve the cohesion, attraction and execution of the Federation of Industry and Commerce. We should educate and guide the broad masses of people in the non-public sector of the economy, strengthen Socialism with Chinese characteristics’s belief, enhance trust in the Party and the government, and have confidence in the development of enterprises, so as to strive to be excellent builders of Socialism with Chinese characteristics’s cause.

　　BEIJING, Beijing, June 8 (Shang Qi) This year marks the 40th anniversary of the resumption of the college entrance examination system in China. Since 1977, the college entrance examination has influenced and changed the fate of several generations of China people. The gross enrollment rate of higher education has exceeded 40% from less than 2% at first, and is rapidly approaching the 50% popularization index line. Behind the data, how has the college entrance examination influenced and changed China in the past 40 years? 40 years later, what expectations has the college entrance examination been given by this country?

　　the resumption of college entrance examination

　　— — China’s concept of talents is changing.

　　On October 12, 1977, the State Council approved the Opinions on the Enrollment of Colleges and Universities in 1977 formulated by the Ministry of Education, which stipulated the new enrollment policy of colleges and universities, namely, abolishing the recommendation system, resuming the cultural examination, and selecting the best students.

　　This year, the slogan of "respecting knowledge and talents" took root in China. Li Muzhou, director of the Institute of Higher Education of Hubei University School of Education, has studied the examination system in China for many years. In an interview with a reporter from Zhongxin. com (WeChat WeChat official account: cns2012), he said that at the national level, the resumption of the college entrance examination 40 years ago is to show that the country attaches importance to talents and reconstructs the concept of talents.

　　He explained, "the resumption of the college entrance examination has confirmed the basic role of cultural knowledge and intellectual factors in the selection of talents in colleges and universities. This is a major change in the concept of national talents, and it can also be said that it is the correct return of the concept of national talents."

　　Education in China experienced a "warm winter" in 1977. According to statistics, at the end of that year, about 5.7 million young people "returned" to the college entrance examination, and colleges and universities selected 273,000 students, which greatly improved the quality of freshmen.

　　Over the past 40 years, college students selected through the college entrance examination have gone to various fields in China in batches. They witnessed and participated in the whole process of reform and opening up, and gradually became the backbone to promote the development of this country.

　　Recently, Liu Haifeng, member of the National Education Advisory Committee and director of the Examination Research Center of Xiamen University, wrote that since the resumption of the college entrance examination for 40 years, millions of qualified students have been selected for colleges and universities through fair competition in the college entrance examination, and many of them have become the backbone of all walks of life through training. China’s rapid economic development in recent years is inseparable from the recovery and continuous reform of the college entrance examination system.

　　40 years of practice

　　— — From elite education to mass education

　　"The college entrance examination has different meanings for people of different ages." Li Muzhou told Zhongxin.com that before the reform and opening up, the college entrance examination was largely about selecting national cadres. After the resumption of the college entrance examination, with the reform and opening up, the employment of college graduates gradually shifted from planned distribution to market competition, and more and more college graduates began to choose their own jobs.

　　As experts have said, in the past 40 years, with the changes in the country’s economic and social environment, the college entrance examination itself has also undergone changes. In 1999, the Ministry of Education issued the Opinions on Further Deepening the Reform of the Entrance Examination System in Colleges and Universities, and announced the national college entrance examination reform plan, which opened the prelude to the college entrance examination reform in this period. Since then, self-enrollment, self-proposition by province, and parallel volunteer admission have been explored one after another, and the recruitment methods of colleges and universities in China are more diverse.

　　Also in 1999, higher education in China began to expand the enrollment scale, and the admission rate of college entrance examination also began to rise sharply. According to statistics, from 1998 to 2005, the number of applicants for college entrance examination in China increased by 11.58% annually, and the number of college entrance examinations increased by 23.75% annually. By 2015, the number of students enrolled in higher education in China has reached 37 million, ranking first in the world.

　　According to China Education Online’s 2017 Survey Report, under the background that the total enrollment of college entrance examination has remained stable, the enrollment ratio of college entrance examination in all parts of the country has continued to increase. Among them, the gross enrollment rate of higher education has crossed 40%, rapidly approaching the popularization index line of 50%.

　　Compared with the gross enrollment rate of 1.55% in 1978, some people think that higher education in China has gradually moved from "elite education" to "mass education".

　　Li Muzhou said that higher education will enter the stage of popularization in the future, and the improvement of the popularization rate is conducive to the overall improvement of national literacy. He believes that "the future lies not in whether you have attended a university, but in what university you have attended, and this influence may be even greater."

　　Knowledge changes fate.

　　— — Social strata circulate in relative fairness.

　　From "elite education" to "mass education", behind the overall improvement of the popularization rate, the educational equity behind the college entrance examination has always attracted public attention.

　　Last year, Bian Yanjie, dean of the School of Humanities and Social Sciences of Xi ‘an Jiaotong University and sociologist, presided over a report entitled "Career Opportunities for Rural College Students". According to media reports, all the target samples of the survey came from the existing labor force in the city and were divided into six groups: the first three received higher education, namely, urban college students, rural college students and non-transfer college students; The last three have not yet received higher education, including the general urban labor force, rural-to-non labor force and migrant workers.

　　According to the report, for college students from rural areas to urban areas, they have the same opportunities to work in party and government organs and state-owned enterprises, and they also have the same opportunities to engage in elite occupations, with similar economic income levels, while the three types of non-college students mainly engage in non-elite occupations.

　　Li Muzhou told the reporter of Zhongxin.com that the urbanization process in China is very fast, but the rural population still accounts for the vast majority. Therefore, the college entrance examination provides them with an important way to change their destiny through higher education.

　　The "Implementation Opinions of the State Council on Deepening the Reform of the Examination Enrollment System" issued in September 2014 clearly stated that the number of rural students attending key universities should be increased, and the national special plan for targeted enrollment in rural poverty-stricken areas should continue to be implemented, and key universities should target targeted enrollment in poverty-stricken areas.

　　The opinion also made it clear that subordinate universities and provincial key universities should arrange a certain proportion of places to recruit outstanding rural students from remote, poor and ethnic minority areas. In 2017, the number of rural students entering key universities in poverty-stricken areas increased significantly, forming a long-term mechanism to ensure rural students to attend key universities.

　　Changes and Invariance of College Entrance Examination in the Future

　　— — Do you still believe in "one exam will fix you for life"?

　　In recent years, whenever there is a college entrance examination, there will be doubts about the disadvantages of the college entrance examination in public opinion, such as "a thousand troops crossing the wooden bridge", "one exam will set you for life" and "the baton of the college entrance examination".

　　As for the current examination enrollment system in China, the above-mentioned "Implementation Opinions of the State Council on Deepening the Reform of the Examination Enrollment System" also points out that the examination enrollment system in China is generally in line with the national conditions, authoritative and fair, and is recognized by the society. However, there are also some problems that are strongly reflected by the society. The main reason is that the score theory affects the all-round development of students, and the students’ learning burden is too heavy. There are gaps in enrollment opportunities between regions and urban and rural areas, and the phenomenon of cheating extra points and illegal enrollment occurs from time to time.

　　Nowadays, the scale of high school graduates studying abroad in China is increasing. It is pointed out by some voices that the growing number of students studying abroad also reflects from one side that parents and students in China are "voting with their feet" in the face of the college entrance examination.

　　"This will force the reform of the domestic college entrance examination system." Li Muzhou said that the foreign enrollment system has its advantages, such as multiple examinations, rich and flexible subject design, and relatively strong autonomy of colleges and universities … … These are problems that have not been completely solved in China’s college entrance examination system.

　　In fact, the practice of the college entrance examination in the past 40 years has not remained unchanged. Qu Zhenyuan, president of China Higher Education Society, pointed out to the media that in recent years, all aspects of college entrance examination enrollment have been reformed, including examination subjects, examination contents, examination times, examination methods, scoring methods, proposition methods, voluntary reporting methods, admission system, college entrance examination time, and charging system, and almost no aspect has not been tried or touched.

　　The latest changes have appeared in this year’s college entrance examination. These days, high school graduates in Shanghai and Zhejiang are welcoming the first "new college entrance examination". The results of the college entrance examination are composed of three unified college entrance examination scores of Chinese, mathematics and foreign languages, and three students’ self-selected examination subjects. The foreign language test is changed from once a year to twice a year, and you can choose a better score to be included in the total score of the college entrance examination.

　　Chu Zhaohui, a researcher at China Academy of Educational Sciences, said in an interview with Zhongxin.com that the reform of the college entrance examination enrollment system will be in a period of fluctuation in the coming period, and the key to the reform of the college entrance examination is to implement more professional evaluation.

　　He said, "The current examination system can achieve good results through a lot of training, and the actual test results are relatively distorted. As a professional education evaluation, the influence of intensive training on the test results should be eliminated as much as possible."

　　Li Muzhou hopes that through the reform of system design, the situation of "one exam will be fixed for life" will be changed.

　　"For example, let students have multiple exams and even multiple admissions opportunities, and further strengthen the separation of recruitment. Colleges and universities should study their own school-running orientation, formulate examination plans that meet their freshmen’s characteristics, and gradually break the people’s inherent understanding of the college entrance examination." He said.

　　Obviously, 40 years later, the college entrance examination still carries the heavy expectations of this country. (End)

Yunnan golden monkey is a national first-class protected animal, which is mainly distributed in the alpine virgin forests in northwest Yunnan and southeast Tibet. It is known as the "Snow Mountain Spirit" and an endangered species in the red list of the World Conservation Union.

This is the Yunnan golden monkey in Shangri-La Yunnan Golden Monkey National Park, Diqing Tibetan Autonomous Prefecture, Yunnan Province (photo taken on March 16).

Around 1980s, hunting and logging destroyed the habitat of Yunnan golden monkey, and the number of monkeys once decreased, so the protection situation was grim. In order to save the endangered Yunnan golden monkey, China established Baima Snow Mountain Nature Reserve, explored the protection mode of "community condominium", combined protection with the survival and development of surrounding residents, and promoted the recovery growth of Yunnan golden monkey.

The monitoring results of Yunnan Forestry and Grassland Bureau show that after years of efforts, the protection effect of Yunnan golden monkey is obvious. The population of Yunnan golden monkey increased from about 1000 to 1500 in 13 groups in 1996 and 3000 in 18 groups in 2016 to more than 3300 in 23 groups at present.

Since 2019, 13 organizations including Yunnan Forestry and Grassland Bureau, Yunnan Green Environment Development Foundation and Nature Conservancy (TNC) have jointly launched the "Yunnan Golden Monkey Whole Territory Protection Network", trying to establish a multi-party joint protection mechanism, taking actions from patrol monitoring, corridor restoration, community participation, friendly development and public participation, and striving to achieve sustained and healthy growth of Yunnan Golden Monkey population and comprehensive improvement of the health level of its habitat ecosystem.

[EV Vision Technology Comparison] Nowadays, when vehicle electrification has become the mainstream of development, diesel locomotives seem to gradually withdraw from the rhythm of the historical stage. However, the reality proves that the models with internal combustion engines will not disappear for a long time to come, but will have certain advantages in some aspects. However, this species that does not suffer from "mileage anxiety" will make car owners suffer from another disease-"fuel consumption anxiety". Therefore, on the issue of how to treat it, plug-in hybrid models have become this good medicine.

Before, we made a comparison between BYD DM-i and Great Wall Lemon DHT (extended reading: BYD DM-i or Great Wall Lemon DHT, who represents the peak of domestic hybrid technology? ), which proves that domestic hybrid technology is gradually rising and has the strength to compete with foreign hybrid technology. Of course, this technical field in China is more than these two. Looking at the industry, basically most OEMs have started to develop their own latest hybrid technology, and among them, Chery’s Kunpeng DHT has become another new hot spot after the first two. If you look closely, you may find that compared with the hybrid technology of the Great Wall, the word DHT appears behind Chery’s technology. What is the difference between it and lemon DHT?

What does DHT mean?

If you answer what is the most obvious difference between Kun Peng DHT and lemon DHT, there is actually a difference in word meaning.

The DHT of great wall lemon is calledDedicated Hybrid Technology, the Chinese translation isSpecial technology for hybrid power, is a complete hybrid technical scheme, including engine, transmission, drive axle, battery and other components.

DHT of Great Wall Lemon

Chery Kunpeng’s DHT is calledDedicated Hybrid Transmission, that isSpecial gearbox for hybrid powerBased on the traditional fuel vehicle gearbox, some electrified components are added to realize hybrid power technology.

DHT of Chery Kunpeng

So it can be seen that there are some differences in the technical route between the two. Please look down.

Comparison of hybrid architectures

Dual-motor+engine combination may be the trend of hybrid technology development now. Take DHT of Great Wall Lemon as an example, it is a powerful three-engine/four-engine power system composed of a 1.5L/1.5T hybrid special engine, a highly integrated dual-motor hybrid gearbox and a 135kW three-in-one two-gear electric drive rear axle. Under this system, three different specifications of power (PHEV/HEV) assemblies suitable for Class A, Class B and Class C have been successively introduced. In addition, under the PHEV architecture, there is also a "1.5T +DHT130+P4" four-wheel drive powertrain, which corresponds to different levels of products to meet the diversified choices of users.

Specifically, the lemon hybrid DHT consists of a high-efficiency hybrid special engine, a highly integrated dual-motor hybrid gearbox and a 135kW three-in-one two-speed electric drive rear axle, forming a powerful three-engine/four-engine power system, which brings super power. The maximum power of HEV two-drive system is 180kW, and the total power of PHEV two-drive system can reach 240kW. The front and rear axle motors with PHEV+P4 structure can output power at the same time, and the maximum system total power can reach 320kW. The intelligent four-wheel drive system of this architecture has strong climbing ability, such as achieving 60%-65% maximum climbing degree when dry asphalt pavement and 15%-18% maximum climbing degree when snow.

High fuel efficiency hybrid special engine

In terms of transmission, Great Wall Lemon DHT is similar to Honda i-MMD, except that it has two gears when the engine is driven, while the latter has only one gear when the engine is driven. By selecting the gear, it can give full play to the performance advantages of the engine. The system also adopts dual-motor series-parallel topology, which can realize EV, series connection, parallel connection, energy recovery and other working modes, and achieve a perfect balance between power and fuel consumption in various driving scenarios. As for the battery, the Great Wall Lemon DHT architecture is equipped with the world’s largest capacity and high-efficiency hybrid battery, which has the highest performance in the industry with a pure battery life of 200km. With CTP(Cell to Pack) technology, the energy density of the battery pack reaches 160Wh/kg, and it supports 11kW AC slow charging and DC fast charging.

High integration hybrid DHT transmission

Although there is not much information about Chery Kunpeng DHT, we can still see the clue from the known information.

From this exploded view, we can roughly see the structure of the whole system. Chery Kunpeng DHT also uses the combination of engine and dual motors, but here I want to knock on a blackboard to draw a key point. Different from the mainstream development, Kunpeng DHT is the only hybrid architecture driven by dual motors in China brand at present. An output mode mainly driven by electricity can be provided. In this hybrid system, the motor bears the main driving responsibility, and the engine can supply energy for the power battery under low load conditions. Therefore, two relatively low-power drive motors are equipped with FIO fixed-point injection oil-cooled motor technology and TEM dual-motor power distribution technology developed by Chery, in order to replace the effect of a single high-power drive motor.

In terms of data, the maximum power output torque of Kunpeng DHT can reach 510N·m, and the whole box torque density is 35 N m/kg, which can match large and medium-sized cars and SUV models, and can realize nine high-efficiency working modes such as single/double motor drive, extended range, parallel connection, direct engine drive, single/double motor braking energy recovery and driving/parking charging. Kun Peng DHT adopts TEM ultra-efficient dual-motor power distribution technology, which can choose the best electric drive source and gear according to the load size to improve the driving efficiency, thus creating a smooth driving experience and more efficient power distribution. The maximum transmission efficiency is more than 97.6%, the average efficiency of electric drive in NEDC working condition is more than 90%, the peak efficiency of flat wire motor is more than 97%, the power is 6.0kW/kg, and the fuel saving rate in low power mode is more than 50%.

In addition, Kunpeng DHT has 11 combined gears (seemingly the largest in the world? ）。 However, it should be noted here that the gear position of Kunpeng DHT is not limited to these 11 combinations. Due to the existence of dual motors and the provision of a 3-speed transmission device in the engine direct drive mode. You know, most of the mainstream technologies now adopt a direct clutch structure, that is, the generator can directly drive the wheels. However, when they are all direct-drive output, they all have only one gear, which limits the highest efficiency working range (the difference between ordinary bicycles and variable-speed bicycles), so Kunpeng DHT is equipped with three gears on the engine to broaden the engine driving performance. First of all, the first speed ratio is relatively large, which is mainly used for starting and accelerating. The third speed ratio is very small, mainly to ensure low engine speed, low fuel consumption and noise reduction when driving at high speed. Among them, the second speed ratio mainly takes into account the shift of the first gear and the third gear to ensure the smoothness of the shift, and at the same time takes into account the fuel consumption at the middle and low speeds.

It is worth mentioning that these permutations and combinations can achieve dozens of gear combinations, but the manufacturer has chosen 11 most suitable gears. In different working scenarios, the built-in control system of Kunpeng DHT calculates the optimal working gear in real time, and cooperates with Chery’s FIO fixed-point injection oil-cooled motor technology, TEM ultra-efficient dual-motor power distribution technology and ultra-smooth TSD dual-shaft drive design to achieve the balance of power, ride comfort and economy.

Comparison of working principles

There are four working modes of Great Wall Lemon DHT, including pure electric drive mode, series mode, first gear direct drive mode (low speed cruise), first gear direct drive mode (performance direct drive), second gear direct drive mode (high speed cruise) and energy recovery mode.

The important core of overall fuel saving is to make the engine work in an efficient working point area. When driving at low speed in general urban areas, lemon DHT will switch between EV mode and series mode, and maintain the engine in the most efficient area. When driving in suburbs and viaducts, the series mode will still be adopted at medium and low speed, but at medium and high speed, the engine will start to intervene, and when encountering heavy load demand, the engine+parallel drive mode will be adopted, which not only maintains high efficiency, but also provides sufficient response for power. Finally, at high speed, the engine direct-drive working point will directly fall in the high-efficiency area, or when the power is enough, EV battery life will be adopted to reduce fuel consumption.

As can be seen from the published data, the working mode of Chery Kunpeng DHT can be said to be another way.

First of all, the front part will be equipped with a small displacement (1.5T) inverted engine. Why did you choose this engine type? First of all, the intake manifold of the inverted engine is shorter, and the air intake is more direct and smooth. In addition, the air does not need to be heated above the engine to reduce the air density and oxygen content, so the engine burns more fully, the thermal efficiency is higher than that of the upright engine, and the fuel consumption is correspondingly reduced. In addition, this engine has a relatively compact volume to reduce the cabin space and lay the foundation for weight reduction because the intake manifold and exhaust manifold do not need to be wound up and down from the engine for half a turn.

The dual-motor part of the predecessor is composed of two low-power driving motors. Why choose two low-power drive motors but not one high-power motor directly? The reason for this is that if a high-power motor is used, the efficiency of the motor will be greatly reduced at first when it starts at low speed and runs at high speed, and when it enters the power loss state, the engine will start to intervene in power generation, and the fuel consumption will inevitably increase. Therefore, using two low-power motors can make the whole hybrid system work in a high-efficiency area with the same comprehensive performance. After that, it is combined with the previously mentioned Kunpeng DHT gearbox to achieve the purpose of fuel saving. In addition, after adopting the dual-motor scheme in manufacturing cost, the dependence on high-precision gears is relatively reduced. After all, this aspect can only rely on imports for the time being.

Who are the models under DHT technology?

WEY macchiato

On April 15th this year, Great Wall Motor conducted an online lemon hybrid DHT vehicle test, which was the first time to be tested with a real vehicle. The tested model was WEY Macchiato, which will be listed soon. This model is equipped with the latest lemon hybrid DHT technology of the Great Wall, and is also equipped with the combined configuration of 1.5L Atkinson cycle engine and motor. The maximum horsepower of the engine is 102kW, the maximum power of the motor is 154kW, and the combined maximum power is 190kW. It is worth mentioning that the fuel consumption per 100 kilometers is only 4.7L and the maximum cruising range can reach 1100km. The subsequent PHEV plug-in hybrid vehicle has a pure electric cruising range of 110km.

Tiggo 8 PLUS PHEV

Tiggo 8 PLUS PHEV is Chery’s first model equipped with DHT hybrid system, which adopts a three-motor four-wheel drive hybrid system with 1.5T turbocharged engine+front double motor+rear single motor. Among them, the maximum power of the engine is 125kW, the peak torque is 252N·m, the official 0-100km/h acceleration is only 4.9 seconds, and the comprehensive fuel consumption is only 1.3L/100km.

EV vision view:Although the published information is very limited, through the comparison of these two technologies, we can see that their innovation in hybrid technology is enough to compete with hybrid power enterprises, which not only opens the door to the development of domestic hybrid technology, but also makes China brand occupy a place in the world. At present, the latest "Roadmap 2.0 for Energy-saving and New Energy Vehicles" issued by China Automotive Engineering Society clearly puts forward that traditional vehicles should be fully "mixed" in the next 15 years. By 2035, among the non-new energy vehicles that still occupy half of the market, hybrid power will become the leading force. Therefore, the automobile industry has developed in parallel with many technical routes. In order to realize the low-carbon of energy-saving vehicles, the automobile factory must establish a new hybrid technical route. Therefore, both Kunpeng DHT and Lemon DHT will become the new trump cards representing the development of hybrid technology in China. In the future, EV Vision will dynamically evaluate two vehicles based on its own hybrid technology, so stay tuned!
