Issue: Introduce the latest situation of epidemic prevention and control in Lianyungang.

Wang Xiujie: Now we will hold the 15th press conference of this epidemic. First of all, please ask Yang Xinzhong, member of the Standing Committee of the Municipal Party Committee and executive deputy mayor, to report the situation of epidemic prevention and control in our city.

Yang Xinzhong: I mainly report three aspects:

I. General situation of epidemic situation

From 00: 00 to 24: 00 on March 19th, there was no new confirmed case in COVID-19, and one asymptomatic infected person was added. The relevant information has been published through media platforms such as "Lianyungang Release". Up to now, this round of epidemic has reported a total of 145 local confirmed cases and 133 asymptomatic infected cases.

II. Relevant work carried out since yesterday

1, nucleic acid detection. A new asymptomatic infection case was found in a centralized isolation point yesterday.

2. Medical treatment. Yesterday, 11 confirmed cases were cured and discharged, and 12 asymptomatic infected people were released from isolation medical observation. Since the current epidemic, 59 people have been cured and discharged, and 33 asymptomatic infected people have been released from isolation for medical observation. All of them have been transferred to designated rehabilitation hospitals for medical observation and health management.

3. Delineation of risk level. After comprehensive evaluation and judgment, today, three medium-risk areas in Haizhou District have been adjusted to low-risk areas, and the control measures of their residential areas have been lifted. Relevant information has been announced through media platforms such as "Lianyungang Release". The risk levels in other regions remain unchanged.

4, the city personnel from the company and rescue. Introduce the policy of personnel separation within the city to ensure the orderly flow of personnel. In society, we will carry out a special activity of "Cold Spring in send warm" to actively protect the lives of stranded people and help those who are temporarily in trouble and vagrants and beggars.

5. Remove centralized isolation. As of 7: 00 today, a total of 4,229 people were released from centralized isolation in this round of epidemic, and all the requirements such as closed-loop transshipment and home monitoring were implemented according to regulations.

6, sealed control area life, medical security. Organize 18 large and medium-sized supermarkets to "peer-to-peer" docking, control and control communities, and ensure the supply of daily living materials for residents. Since the current epidemic, the elderly, pregnant women and children have been helped to seek emergency medical treatment for 96 times, and the basic living needs such as purchasing medicine and buying vegetables have been solved for more than 4,000 times.

Third, the next work arrangement

First, continue to classify and carry out nucleic acid detection. For the sealed control area, the control area, the building where the case is located or the natural village, all personnel will carry out nucleic acid sampling and testing at different times.

The second is to implement control by zoning and grading. Counties and functional sectors without local cases have turned into normalized epidemic prevention and control, and production and living order have been restored in an orderly manner. We will continue to strictly implement control measures for key areas in Haizhou District. For other areas in Haizhou District and counties and functional sectors where local cases have occurred, the scope of control will be gradually adjusted, and the risk levels and related prevention and control measures will be adjusted in real time for eligible medium-risk areas, closed control areas and control areas.

The third is orderly transshipment and isolation. For those who are released from centralized isolation, a special class for transshipment and connection will be set up to ensure safe and orderly closed-loop reception and rejection.

The fourth is to ensure the supply of living materials. Adhere to the external supply and fixed-point supply, further strengthen the allocation of living materials and strength, and further open up the distribution end of living materials.

Reporter: Just now, Mayor Yang mentioned that there are three medium-risk areas in our city that have been adjusted to low risk, and their communities have been unsealed and deregulated. What is the standard for unsealing? Do you have any requirements after unsealing?

Chen Zhi: According to the current situation of epidemic prevention and control, in order to coordinate the epidemic prevention and control and economic and social development, our city adheres to scientific and precise prevention and control, and is dynamically adjusting prevention and control measures. After evaluation and careful judgment by provincial and municipal experts, our city has adjusted the No.3 Building of Runqiyuan, No.4 Building of Tianjing Meidi and B2 Building of Wenqiao Lvyuan in Haizhou District from a medium-risk area to a low-risk area, and the control measures for their residential areas have been lifted. At the same time, the city’s closed control areas and control areas have also begun to gradually unblock and control.

We strictly implement the national standard of "Community Prevention and Control Plan for Epidemic in COVID-19". For the closed control area and the control area, the control is downgraded according to the principle of "two 14-day, one round of negative", that is, there is no positive infected person in the community within 14 days, and the last close contact has not detected positive nucleic acid since the last exposure for more than 14 days, and the nucleic acid test of all the community members is negative two days before unsealing; For the prevention area, when there is no closed control area or control area within the jurisdiction, it will be unsealed and released naturally.

After unsealing, we insisted on unsealing without understanding prevention, service and responsibility, and strictly implemented prevention and control measures for normalized epidemic situation in unsealed areas. First, strengthen the education and guidance for residents who have been unsealed and continue to do a good job of self-protection; Second, the gathering places in the community continue to be temporarily closed, and gathering activities are strictly prohibited; Third, entering the community must strictly implement the requirements of bright code, temperature measurement and wearing masks. Fourth, continue to do a good job in disinfection of internal and external environment, especially to strengthen daily disinfection of key parts such as elevator rooms, handrails and garbage bins; Fifth, strengthen humanistic care, help residents solve practical difficulties, and do a good job in psychological counseling of relevant personnel.

In addition, for counties without local cases, the production and living order will be restored in an orderly manner. From 0: 00 on March 18th, guannan county, Ganyu District and Xuwei New District have been transformed into normal epidemic prevention and control. The first is to restore traffic order in an orderly manner. Traffic bayonets within the jurisdiction were released in an orderly manner and circulation resumed. At the same time, strict "external defense input" control measures. The second is to restore industrial and agricultural production in an orderly manner. Industrial enterprises, construction sites, etc. strictly implement normalized prevention and control measures, resume production and construction in an orderly manner after acceptance, and actively carry out spring ploughing production. The third is to restore offline teaching in an orderly manner. On the basis of strict implementation of various prevention and control measures, the first batch of senior three resumed offline teaching, and other grades resumed offline teaching in an orderly manner and in batches. The fourth is to restore the flow of personnel in an orderly manner. Villages and community communities have implemented "one bayonet" access, and the staff of government agencies, enterprises and institutions have resumed their normal work in an orderly manner. Continue to restrict group gathering, entertainment places and business places with relatively closed space and relatively concentrated personnel will be suspended from opening to the outside world, all kinds of personnel gathering activities will be suspended, and catering units will continue to suspend the provision of dining services. The recovery time will be notified by the localities as appropriate.

Reporter: In many scenes of epidemic prevention and control, we can see firefighters. I want to ask, what kind of work does the fire department mainly undertake? What are the tips for citizens’ home fire safety?

Yang Hualin: After the outbreak in our city, as the main force and national team of emergency rescue, the city’s fire rescue workers actively participated in the anti-epidemic battle. The main work is as follows:

First, actively undertake epidemic prevention service work. 115 elite troops have been dispatched to participate in epidemic prevention service, and the support services such as accommodation and material handling, nucleic acid testing laboratory construction and complete transshipment of reinforcements have been completed efficiently and with high quality. Dispatch 10 fire engines and 50 fire rescue workers, divide them into 10 groups, and assign them to hospitals and centralized isolation points in the city to make overall plans for epidemic prevention, decontamination and fire fighting and rescue.

The second is to actively participate in epidemic prevention and disinfection. Quickly set up an epidemic prevention and disinfection commando team, and use fire engines such as smoke exhaust and water tanks to carry out disinfection operations in Lunan Street, Xinhai Street, schools and supermarkets. Use backpack aerosol sterilizer and other equipment to go deep into risk areas and carry out "carpet disinfection" every day. Up to now, a total of 136 fire engines (times) and 601 fire-fighting personnel (times) have been dispatched, and 147 residential and public places have been disinfected, with a cumulative disinfection area of about 190,000 square meters. In addition, co-ordinate and guide the county fire rescue teams to participate in the resident epidemic prevention and disinfection work, and enrich the local epidemic prevention forces.

The third is to strengthen the prevention and control of social fires. Make full use of the "on-site+remote" mode, such as fire network monitoring system, remote video, SMS prompt, telephone guidance, to conduct all-round inspection and guidance on epidemic-related sites and key supply protection units, and focus on strengthening fire supervision and management of people’s livelihood security sites such as supermarkets and markets. Since the outbreak, a total of 1071 epidemic-related sites have been inspected, helping to rectify 548 hidden dangers; Inspected and guided 249 water, electricity, supermarket and other life security enterprises (times) to help rectify 181 hidden dangers; More than 100,000 fire safety tips were sent, effectively ensuring fire safety and stability.

The fourth is to go all out to do fire fighting and rescue. Further improve the emergency plans such as the compilation of the city’s fire rescue forces, emergency response, and cross-regional reinforcements during the epidemic prevention and control period, and deploy special forces to form an emergency mobile team to maintain the state of "emergency operations" at all times. In view of the situation of community closure and road control, emergency demolition and emergency linkage plans are formulated to ensure that the rescue operation will not affect or delay. Up to now, a total of 230 police officers have been dispatched, 361 fire engines (times) and 2,100 people on duty (times) to carry out fire fighting, emergency rescue and various kinds of assistance. The fire situation is generally stable.

I would like to take this opportunity to remind everyone that while fighting the epidemic, we should keep in mind fire safety and pay attention to the safety of using fire, electricity and gas; Clean up the flammable and combustible materials in the kitchen, balcony and corridor in time; Smoking in bed at home; Do not charge the battery car indoors; It is forbidden to occupy the fire safety evacuation passage. Please keep these fire knowledge and regulations in mind, do not forget fire prevention during epidemic prevention, and jointly protect a safe and beautiful home!

Reporter: Today is the vernal equinox among the 24 solar terms, and agricultural production is about to enter the busy period of spring ploughing. Excuse me, what measures have we taken to do a good job in spring ploughing production under the situation of epidemic prevention and control?

Chen Feng: After the outbreak, the Municipal Bureau of Agriculture and Rural Affairs immediately launched an emergency response to coordinate the prevention and control of the epidemic, stable production and supply, and spring production. According to the recent agricultural situation scheduling, this year, the area of wheat in the city is about 3.7 million mu, and the situation of wheat seedlings is slightly worse than that of the previous year, but it is generally a preferred year. As the saying goes: "Wheat rises at the vernal equinox, and every moment is worth a thousand dollars", and spring ploughing and preparation for ploughing have entered a critical season. In order to lay a solid foundation for high yield of summer grain and ensure that the farming season and farming are not delayed, we have focused on the following aspects:

First, strengthen overall planning. The Municipal Bureau of Agriculture and Rural Affairs set up a temporary headquarters for the prevention and control of sudden epidemic situation, formulated and issued a series of documents such as the Notice on Strengthening the Rapid Implementation of Increasing the Supply Capacity of Green Vegetables during the epidemic situation, and coordinated the prevention and control of epidemic situation and agricultural production. Five working groups were set up to ensure spring ploughing and promote production, and Baoxian County guaranteed the stable production and supply of vegetables, field management of wheat in spring, and preparation for spring ploughing, etc., to help the grassroots solve the problems in spring agricultural production in time.

Second, carry out precise guidance. We formulated technical guidance for the production of wheat, vegetables, fruit, animal husbandry and aquatic products under epidemic prevention and control, organized more than 100 agricultural technicians in cities, counties and townships to set up an expert group for spring ploughing and preparation during the epidemic, and carried out technical guidance nearby, and successively issued 12 spring technical guidance for field management at jointing stage of wheat. Explore the mode of "on-line farming preparation" and "on-line spring management", and use the network platforms such as agricultural technology platform and WeChat official account, and focus on providing online technical guidance and remote network training for new business entities such as family farmers, large growers and agricultural cooperative organizations. Guide farmers to do a good job in wheat field management in combination with the actual situation, and implement measures such as clearing furrows in farmland, removing soil moisture in spring, returning to green, jointing and topdressing, controlling pests and diseases, preventing late spring cold, and drought-resistant irrigation to promote wheat to increase ears and tillers. Up to now, 2.1 million mu of furrow cleaning and soil moisture control have been completed, with 3.1 million mu of chemical removal area, 760,000 mu of pest control, 2.15 million mu of spring irrigation and 2.65 million mu of returning green and jointing fertilizer.

Third, strengthen supply and marketing security. Formulate an emergency vegetable supply plan, open up a "green channel" for vegetables in the local market, establish a franchise pass system, implement a daily newspaper system for 121 key vegetable supply bases, and organize various forms of production and marketing docking to ensure the normal circulation of "vegetable basket" products during the epidemic. Set up a special fund for "increasing the supply capacity of green vegetable bases during the epidemic period" to guide the producers to adjust the variety layout and expand the varieties of sprouts and leafy vegetables to ensure the needs of the citizens. Carry out the online purchase mode of agricultural materials with "online ordering and offline distribution", implement the policies and measures to ensure the transportation and supply of agricultural materials during the epidemic prevention and control period in our city, and fully organize the supply of agricultural production materials such as pesticides, seeds, fertilizers and nursery materials. More than 20 seed production enterprises and more than 1,900 agricultural materials stores in the city have sufficient reserves, which effectively guarantee the needs of agricultural production.

Fourth, optimize the service of helping agriculture. In view of the problem of slow sales of strawberries in the East China Sea, we actively coordinated the handling and issuance of transport vehicle passes for fresh agricultural products, and actively docked large and medium-sized supermarkets and other key supply-ensuring units to help farmers broaden their sales channels. In view of the epidemic situation affecting the production and marketing of tomatoes in our city, experts were organized in time to formulate measures such as delaying harvest and long-term preservation after harvest, and they were pushed to large tomato growers in the city through the network. In view of the poor soil moisture and serious drought in Gangling area in the west of our city since the beginning of spring, we cooperated closely with the meteorological department to implement artificial precipitation enhancement on March 12 and March 14, respectively, which basically alleviated the spring drought problem.

In the next step, we will pay close attention to the situation of epidemic prevention and control, carry out dynamic guidance services, achieve "two-handed prevention and production", ensure high-standard and high-quality agricultural production in spring, and lay a solid foundation for high-yield agricultural harvest throughout the year.

　　Xinhua News Agency, Changsha, September 11th-From the ancient wisdom of mental arithmetic and abacus calculation to the creation of "China Speed" by "Galaxy", "Tianhe" and "Shenwei", China Calculation has attracted worldwide attention.

　　How to break the "limit" of computer technology? How to greet "industrial transformation" Where will computers go in the future? … … From September 9 to 11, 2019 World Computer Congress was held in Changsha, Hunan Province, the hometown of "Galaxy" and "Tianhe" supercomputing. Computer "big coffee" from all over the world talked about the future of computer technology and industry.

　　Calculate everything

　　The Root of Modern Science and Technology and the Source of Innovation

　　Through the "5G+ holographic remote interactive teaching", students can listen to teachers thousands of miles away and interact in real time. On the computer desktop supported by the "slap machine", the mouse can "play" the HD video of the cloud host in a second; Wearing "security glasses" can immediately identify people who come into sight … … At the 2019 World Computer Congress, the new application of digital technology shows the infinite possibilities of the future world.

　　The Zhouyi unearthed from Mawangdui Han Tomb in Changsha records the ancient "algorithm" in the 2nd century BC, and the world’s earliest multiplication formula table unearthed from Liye Ancient City in Xiangxi, Hunan Province explains the "computational wisdom" in the Qin Dynasty. The abacus calculations used in Taiping Ancient Street and Jinggang Ancient Town in Changsha from ancient times can meet the four operations of big data, but now, the "Galaxy" and "Tianhe" supercomputing have repeatedly created new ones. … From mental calculation, abacus calculation to super-calculation, Hunan witnessed the leap of "China calculation" for thousands of years.

　　Computers have been widely used so far, but in just a few decades, human beings have been "deeply immersed" in the "ocean" of information.

"If the digital industry and digital technology are described as a rocket, computing power is the engine of this rocket." Cao Zhiping, senior vice president of Dell Technology Group, said.

At present, China has become the world’s largest computer manufacturing base, with the world’s largest computer market and application scenarios, and the computer industry ranks first in the world. In 2018, China’s computer industry achieved a main business income of 1.95 trillion yuan; The output of microcomputers is 310 million, including 170 million notebook computers; The output of servers reached 2.952 million units, a year-on-year increase of 34.6%. Lenovo, Huawei, Inspur and other key enterprises have steadily increased their share in the global market of notebook computers and servers.

"Mankind is entering the era of intelligence, networking and digitalization, and computer technology and industry have become the key to a local economic and social development. Let’s talk about computers now, not just the development of hardware products such as PC, notebook computer and server, but the whole computer industry ecology including all kinds of new computing and emerging applications. It is a solid foundation of modern science and technology and a source of innovation. " Liu Wenqiang, vice president of China Electronic Information Industry Development Research Institute, said.

Wu Manqing, an academician of China Academy of Engineering and general manager of China Electronics Technology Group Co., Ltd., believes that with the continuous development of information technology, the future world will be characterized by all-encompassing, virtual and real integration, collaborative sharing, and continuous compression of time and space, and will be more deeply "intelligent".

　　"Calculation power" means "productivity"

China calculates to climb "the top of the world"

It takes one year to complete the correlation analysis of genome-wide information with a scale of 500 people, and only three hours to use Tianhe-2. A train has more than 2800 parts, and the supercomputer can identify them all in less than one second, and judge whether there are cracks and other faults; It used to take two years to develop a large aircraft and do the aerodynamic test of the whole aircraft. Using supercomputer simulation, the related work can be completed in six days … …

With the rapid evolution and wide application of information technology, "computing power is productivity" has become a global consensus. As the carrier of computing power, computers have gradually become a new type of infrastructure, providing a strong impetus for global scientific and technological and economic development.

Although it started late, a series of supercomputers in China, from "Galaxy" to "Tianhe" and "Shenwei", are well-known "China brands" in the world. China Supercomputer not only achieved many firsts in independent innovation, but also climbed to the world’s "speed peak" for several generations — — "Tianhe" has won the fastest computing speed of supercomputers in the world for six times.

With the continuous development and improvement of the application system, supercomputers play an increasingly important role in supporting national scientific and technological innovation, serving the national innovation drive and local industrial development. "At present, supercomputing has achieved a series of innovative achievements in large-scale parallel computing in the fields of atmospheric and marine environment, numerical wind tunnel, medical information, genomics, pharmacy, electromagnetism and astronomy." Li Qiong, a researcher at Computer College of National University of Defense Technology, said.

Up to now, China has built six national supercomputing centers in Tianjin, Changsha, Guangzhou and other places, providing new kinetic energy for innovation-driven development. At present, supercomputing has gradually penetrated into all aspects of "calculating the sky", "calculating the land" and "calculating people" and has become a "super brain" to solve world problems.

"We are building a new generation of E-class computers in Tianhe, which will have the ability to calculate billions of times per second." Li Qiong told reporters.

"E-class supercomputer" is recognized as "the next crown of supercomputer". At present, the national "Thirteenth Five-Year" high-performance computing special project three E-class supercomputer prototype systems — — Shenwei E-class prototype, "Tianhe III" E-class prototype and Shuguang E-class prototype system have all been delivered.

Change is imminent.

Future development will be beyond imagination.

Developing a fine numerical weather forecasting system based on supercomputing platform can accurately predict the meteorological changes in the next 15 days and greatly increase the disaster preparation time for severe weather; Osteoporosis artificial intelligence screening robot can accurately "ask" osteoporosis and provide personalized diagnosis and treatment report within 3 to 5 minutes, with an accuracy rate of over 90%… …

Nowadays, the door of the digital economy era has been opened, and the core technology system in the ICT field based on the computer industry is accelerating reconstruction, which has become an important engine to drive industrial transformation and upgrading and economic and social development.

"Under the support of the rapid improvement of computing power, the continuous evolution of algorithms and the rapid growth of big data, intelligence has entered a period of rapid development. The deep integration, comprehensive innovation, comprehensive penetration and comprehensive application of intelligent technology will profoundly change human social life, change the world and open a new era of intelligence. " Qiao Yueshan, director of the Electronic Information Department of the Ministry of Industry and Information Technology, said.

Experts attending the meeting said that at present, the development of computer industry in China is showing a diversified trend, and a series of new disciplines have been formed simultaneously with developed countries abroad. These disciplines have developed rapidly, and many fields have reached or even surpassed the foreign level in technology research and development or industrialization in the same period.

At the same time, the computer industry itself is brewing new changes. Experts attending the meeting believe that the development of the global computer industry has once again reached a "crossroads", facing unprecedented opportunities and challenges.

On the one hand, the semiconductor process that affects the computing power is approaching the limit, Moore’s law is facing "failure", and the traditional centralized, distributed and cloud-based architecture is facing a bottleneck; On the other hand, there are many new applications in the computer field. The introduction of artificial intelligence technology and the cross-integration of information technology and economic and social aspects have brought more complex and novel application scenarios, and computers have ushered in a brand-new development space.

"At present, the development of global information technology has entered the era of mobile Internet from the era of desktop Internet. The traditional desktop system has gradually shrunk, and adapting to mobile application scenarios has become the general trend. How to make the computer ecosystem more contemporary has become an important issue in the new era." Rui Xiaowu, chairman of China Electronics and Information Industry Group, said.

What will computers look like in the future? For this problem, many interviewees at this World Computer Congress mentioned quantum computers and biological computers. The former is a physical device for processing and calculating quantum information. The latter is a biological computer that may "replace quantum computers." Therefore, many scientists say that from the development trend, the "future computer" will subvert all the existing inherent concepts of "machine" and is a "high-energy complex" combining electronic technology, optical technology, superconducting technology and electronic bionic technology.

"Computers are developing in the direction of ultra-high-speed, ultra-small, parallel processing and intelligence. In the future, computers will become more and more intelligent, and their perception ability, natural language processing ability, thinking and judgment ability will be gradually improved. The future development of computers will be beyond imagination. " Liu Wenqiang said. (Reporter Su Xiaozhou, Zhang Quan, Xie Ying, Wen Jinghua, Yang Jian, Yuan Yuting, Xi Min)

　　BEIJING, Dec. 6 (Reporter Shangguan Yun) New discoveries have been made in the archaeology of the core protected area in Xianyang City, Qin Dou! Recently, the "First Discovery of the Stone Armor Processing Base of Qin Shihuang Mausoleum" was posted on the hot search: Shaanxi Institute of Archaeology found a hand-made place of stone armor in Qin Dynasty at the site of Xianyang City, Qin Dynasty.

　　This news attracted a hot discussion among netizens who ate melons: What are the uses of these stone armor? Does it have anything to do with the terracotta warriors and horses in Qin Shihuang’s mausoleum? According to Zhang Yanglizheng, assistant researcher of Shaanxi Archaeological Research Institute, these stone armor have nothing to do with the Terracotta Warriors. "There is a burial pit in the mausoleum of the First Qin Emperor, in which Stone armour is unearthed, which is similar to an armor warehouse."

　　New Discovery of the Core Reserve in Xianyang City, Qin Dou

　　Recently, Shaanxi Archaeological Research Institute released a major archaeological discovery: Archaeologists found the remains of stone armor in the core protection area of Xianyang City, Qin Dou, and some features are completely consistent with the stone armor unearthed from the Mausoleum of the First Qin Emperor.

　　It is understood that this newly discovered stone armor production site is located in the ruins of Gaotai building — — Located 500 meters north of the site of No.6 Palace in Xianyang Palace, Qin belongs to Yaodian Town, a new town in Qin and Han Dynasties, Xixian New Area.

　　Archaeologists found scattered stone nails in the surface grass here, and the stones are all cyan limestone. Part of the stone chips are close to the nail plate, the surface is polished, the rectangular hole is drilled, and the edges and corners are treated, especially in order to fit the human body curve, the stone chips are made into the shape of micro-drum on the front and micro-arc on the back.

　　Among them, some stones have words for a moment. These features are completely consistent with the stone armor unearthed from Qin Shihuang’s mausoleum. According to the shape, the stone pieces can correspond to different parts of the armor and the pocket (that is, the helmet) respectively.

　　During the excavation, the archaeological team also found ash pits, powder piles formed by grinding stone chips and other relics, as well as stones, blanks, waste products and chipped slag, copper bars and lead bars used for knitting stone armor, as well as tools such as iron cones, knives and grindstones.

　　The mysterious production place of stone armor

　　Undoubtedly, the discovery of hand-made remains of stone armor is of great significance. This is another major archaeological discovery after the discovery of the stone armor pit in the Mausoleum of the First Qin Emperor 20 years ago and the discovery of abandoned stone armor pieces in the Qin Dynasty water well north of mausoleum of the first qin emperor 18 years ago.

　　Xu Weihong, a researcher at Shaanxi Institute of Archaeology, said that in 1998, the burial pit of stone armor was discovered in the mausoleum of the First Qin Emperor, and a large number of stone armor and bags were unearthed.

　　But how and where they were made remained a mystery until one day three years later. In 2001, Liu Junfa, a farmer from xingfeng, Lintong, dug up a piece of gravel in his cotton field, which was very similar to Qin Ling’s armor.

　　The archaeological team seized this clue and found an abandoned Qin Dynasty water well in Changtiao Village, from which thousands of pieces of discarded stone armor pieces were unearthed, as well as several pieces of flat copper wire used to connect the armor pieces.

　　Most of these stone armor pieces are semi-finished, some are rough, and some have been polished and shaped, with the same texture and shape as the stone armor pieces unearthed in the stone armor pit of the Qinling Mountains. Experts judge that they were all abandoned due to quality problems when making stone armor.

　　theseDoes the stone armor have anything to do with the Terracotta Warriors?

　　Reminiscent of the armor worn by the Terracotta Warriors, some netizens began to wonder: Are those stone armor related to the Terracotta Warriors?

　　Data Map: The "general figurines" unearthed from the No.1 burial pit of Qin Terracotta Warriors and Horses were exhibited for the first time. China News Agency issued Bird photo

　　"They have nothing to do with the Terracotta Warriors. There is no stone armor on the terracotta warriors and horses, and their armor is a clay sculpture made together when making figurines. " Zhang Yang Lizheng introduced that only Stone armour was unearthed in the burial pit of Qin Shihuang’s mausoleum. "You can imagine that it is similar to an armor warehouse."

　　Zhang Yanglizheng explained that the mausoleum of the First Qin Emperor is a complex system. During the Qin and Han Dynasties, the funerary objects of the Mausoleum had a characteristic, that is, they brought all kinds of official institutions of the central government symbolically underground. "In other words, the burial pit in Stone armour may symbolize a part of the armory, because in real life, the Qin Empire should have an armory. It doesn’t have to be for whom to wear it or use it. "

　　The significance of this new discovery of stone armor. Zhang Yang Lizhen said, for example, first of all, you can understand the production process and flow of Stone armour at that time, as well as the production level and skills of handicrafts; Secondly, the internal connection between Xianyang City of Qin and the mausoleum of the First Qin Emperor is closer. "At that time, the official who made the royal funeral utensils should be Shaofu, and Shaofu, as one of the nine ministers, must be in the capital, and the made things will be buried with the emperor."

　　"Third, this discovery provides a new way of thinking for the functional changes of Bei Gong District in Xianyang City, Qin Province after Qin unified the whole country." Zhang Yang Lizheng explained that the workshop area is too close to the palace area, which may be due to the fact that after the unification of the whole country, the Qin Empire planned a new city in the south of Weihe River, centering on Afang Palace, and the function of the original Wei Bei Gong area was transformed into a government office area.

　　On April 3rd, the launching ceremony of the international training plan for artificial intelligence talents in China universities and the opening ceremony of the 2018 artificial intelligence training course for university teachers were held in Yingjie Exchange Center in Peking University.　

　　CCTV News:On April 3rd, the launching ceremony of the international training plan for artificial intelligence talents in China universities and the opening ceremony of the 2018 artificial intelligence training course for university teachers were held in Yingjie Exchange Center in Peking University. The activity was jointly sponsored by the Ministry of Education, innovation works Institute of Artificial Intelligence Engineering and Peking University. At the meeting, the organizer of the event announced the launch of the first international training program for artificial intelligence talents in colleges and universities in China. John E. Hopcroft, a foreign academician of Chinese Academy of Sciences and Turing Award winner, Geoffrey Hinton, inventor of deep learning, and Kai-fu Lee, president of innovation works Institute of Artificial Intelligence Engineering, personally served as teachers. Through multi-level selection, 100 teachers and 300 students are selected from key computer universities in China to participate in the training plan in 2018, so as to explore and practice the teaching content and teaching methods suitable for higher AI talents training in China and cultivate applied talents in China AI industry.

　　Xu Tao, Director of the Department of International Cooperation and Exchange of the Ministry of Education, Tian Gang, Vice President of Peking University, Kai-fu Lee, Dean of innovation works Institute of Artificial Intelligence Engineering, and John E. Hopcroft, winner of Turing Prize, and other leaders and experts attended the launching ceremony. The "International Training Plan for Artificial Intelligence Talents in Colleges and Universities in China" is jointly directed by the Department of International Cooperation and Exchange, the Department of Higher Education and the Department of Science and Technology of the Ministry of Education, co-sponsored by the Chinese and Foreign Humanities Exchange Center of the Ministry of Education, the innovation works Institute of Artificial Intelligence Engineering and Peking University, and co-sponsored by the Beijing Frontier International Institute of Artificial Intelligence. The supporting unit is the School Planning and Construction Development Center of the Ministry of Education. According to the plan of the Ministry of Education, this large-scale plan will train at least 500 AI teachers and 5,000 AI students in top universities within five years to build the largest batch training plan for AI talents in the world.

　　At present, the competition in the field of artificial intelligence is mainly reflected in the competition for talents. According to the People’s Daily, the talent gap of artificial intelligence in China exceeds 5 million. Under the huge talent gap, AI talent education in schools is an indispensable link.

　　In July, 2017, the State Council issued the New Generation Artificial Intelligence Development Plan, which listed "accelerating the cultivation and gathering of high-end talents in artificial intelligence" as a key task, and emphasized "taking the construction of high-end talents as the top priority of artificial intelligence development, improving the artificial intelligence education system, strengthening the talent reserve and echelon construction, and forming China’s artificial intelligence highland".

　　In 2018, the international training plan for artificial intelligence talents in China colleges and universities is a comprehensive training plan of teacher-student interaction, school-enterprise integration and international cooperation, aiming at the pain points of AI education in China.

　　The training plan consists of two parts, the AI training course for college teachers and the DeeCamp AI training camp for college students. This training program has the following characteristics:

　　First of all, invite top international AI masters as mentors. John E. Hopcroft, a foreign academician of Chinese Academy of Sciences and Turing Prize winner, Geoffrey Hinton, the pioneer of deep learning and the father of neural network, and Kai-fu Lee, president of innovation works Institute of Artificial Intelligence Engineering, and other famous experts in the field of artificial intelligence in China and the United States were invited as training instructors.

　　Second, build the world’s largest AI batch talent training program. According to the current plan, at least 500 AI teachers and 5,000 AI students in top universities will be trained within five years, and these teachers will be helped to return to school to open AI courses and train more AI talents. Create a "teacher+student" synchronous training mode. Six weeks of teacher training and five weeks of student training overlap in summer. 100 teachers who participate in teacher training will serve as group assistant academic tutors for 300 students, tracking and learning to promote each other and ensuring teaching quality.

　　Thirdly, the integration of production and learning, interdisciplinary, integration of domestic and foreign high-quality artificial intelligence education resources and industrial resources, and create opportunities for teachers and students to practice in practical topics.

　　Wang Yonggang, vice president of innovation works Institute of Artificial Intelligence Engineering, emphasized the characteristics of the curriculum design of this training program: on the one hand, aiming at the international frontier scientific research direction, inviting academic masters to teach the most advanced teaching concepts; on the other hand, starting from the industrial demand, highly emphasizing the important role of project practice in AI teaching, and designing practical projects that are both challenging and fun for students.

　　Xu Tao, director of the Department of International Cooperation and Exchange of the Ministry of Education, said that it is hoped that through the implementation of the project, the following goals will be achieved:

　　First, further improve the strength and level of artificial intelligence teachers in middle and high schools;

　　The second is to further improve the training ability and level of artificial intelligence talents in China universities;

　　The third is to further build and improve the discipline system of artificial intelligence in China universities;

　　The fourth is to promote exchanges and cooperation between artificial intelligence education and scientific research in Chinese and American universities.

　　Xu Tao, director of the Department of International Cooperation and Exchange of the Ministry of Education, also revealed that the Ministry of Education will further improve the discipline system of artificial intelligence in China universities, and is studying the establishment of an artificial intelligence major to promote the construction of the first-level discipline of artificial intelligence. According to reports, the Ministry of Education is studying and formulating the "Action Plan for Leading Artificial Intelligence Innovation in Colleges and Universities" to further enhance the scientific and technological innovation ability and talent training ability of artificial intelligence in colleges and universities through the integration of science and education and interdisciplinary.

　　In addition, based on this training plan, the Ministry of Education also plans to set up the "Sino-American University Artificial Intelligence Talents Cooperation Training Program" to provide special scholarships for college teachers and students to go to the United States for artificial intelligence; It will also establish the "Sino-US University Artificial Intelligence Talent Training Alliance" in conjunction with relevant American universities to promote educational exchanges and cooperation in the field of artificial intelligence between China and the United States.

Works and books

Zuo Dunping and Implication took a group photo.

　　　　Beijing published a book, Xiaogan moved to heaven and gradually recovered.

　　　　Zuo Dunping wanted his son’s value to be reflected and began to actively look for publishing institutions. Since then, Zuo Dunping’s important job every day is to drag his sick body and carry 3 kilograms of multiple printed manuscripts around Hefei to find a publishing house. However, it is difficult to write a book, and it is even more difficult to publish a book!

　　　　Until the second half of last year, Mei Zihan, a middle school classmate Zuo Dunping had not seen for more than 20 years, suddenly called and told Zuo Dunping that he would visit her in Hefei by the way after returning to his hometown in Lujiang from Beijing. Zuo Dunping was very ill at that time. She said, "Thank you for your kindness. I don’t want my illness to affect your mood." The students were anxious. "If you live well, we won’t see you. If you don’t live well, our husband and wife will stay in the four-star Marriott Hotel opposite your home for 10 days and wait for you!" When Mei Zihan saw that the former school beauty was tortured by the disease and weighed less than 50 kilograms, the famous lawyer in Beijing held her hand and cried.

　　　　When Mei Zihan learned everything about her classmates, she was greatly praised after reading The Adventures of A Feng. "I have a friend who happens to be in the publishing house. Let me try and try my best to make this love of my children blossom and bear fruit!" This classmate brought a copy of the manuscript back to Beijing and handed it to China Federation of Literary and Art Circles Publishing House. A responsible person knew the implied story and couldn’t help sighing that a teenager was so filial. After reading the manuscript, the responsible person immediately decided to publish it. The editor in charge of the book called Zuo Dunping in April this year and said, "The extraordinary life of a young boy is shocking. Although it is a magic novel, the author’s own behavior is a resounding declaration of life to resist adversity, make people cry and motivate their fighting spirit. This draft has selling points, highlights and propaganda points!"

　　　　Because the publication of the book involves procedures such as book number copyright, the author has to pay part of the money first and sign a publishing contract. The money to be spent in the early stage was quietly paid in advance, but Zuo Dunping was not told. When Plum Cold repeatedly called Zuo Dunping to bring his son to Beijing to sign a contract, Zuo Dunping declined. "The child is still in the critical period of the cultural class, and the senior high school entrance examination is about to take place. Once he is allowed to go to Beijing for scenery, he may develop his impetuous psychology and mistakenly think that writing a novel casually can also be used for living. Do everything for you. If I can’t get rid of your affection, I’ll let Implication remember it! " Finally, this novel was edited and designed by Mei Zihan at the end of May 2007. Cao’s dream has finally come true. According to the agreement, according to the sales situation, Cao is about to get a lot of money.

　　　　On June 15th, Cao Xianyu received a parcel at school. When he opened it in wonder, it turned out to be a book sent to him by Beijing Publishing House. When he watched the manuscript turn into type, his scalp was numb with surprise. "God, this is not a dream, is it?" Cao Xianyu was the first to tell his mother the good news. Zuo Dunping held the child’s face in his hands and couldn’t help crying with joy. Students and teachers are also competing to circulate new books with ink fragrance.

　　　　A farmer’s junior three student actually published a book in Beijing. Soon, this explosive news quickly spread to the nearby streets and hometown friends and relatives. They came to congratulate Cao Hanyu and his mother. After learning about it, a local business owner called Zuo Dunping many times and said, "Your husband can work in my business and handle all kinds of social insurance. I am responsible for the tuition fees from Cao Yu to the university!"

　　　　Strangely, Zuo Dunping is determined not to tell his kind boss his address. The explanation of this woman with strong self-esteem is: "This society and relatives and friends have given us too much care. Although we still owe more than 90,000 yuan for medical treatment, our eldest son can get a little subsidy since he has gone to work. We have not reached the desperate situation. I really don’t want to owe too much love to the society. I am afraid that I will not have a chance to repay it in the future!" It turned out that my son’s school knew about Zuo Dunping’s family, which reduced a lot of expenses, and many people helped their family. These, their family all wrote down a note, saying that when their son grew up and had the ability, he would return them all.

　　　　At present, 2000 copies of the first edition of this book have been sold out in 18 yuan. After learning this news, a book city in Anhui Province turned to Zuo Dunping and said that he wanted to plan a signing sale party for Cao Yu to make a name for her son, but Zuo Dunping said: "The work is too immature, and the child’s road has just begun. We can’t let the noise, applause and flowers ruin his enterprising will!" Beijing publishing house and classmates repeatedly called Zuo Dunping to provide the bank card number so as to remit the manuscript fee to her son, but Zuo Dunping refused again: "Students have paid so much for their son’s publishing. If the manuscript fee is even a little small, please ask the publishing house to settle with the classmates who signed the contract. If you owe too much to your classmates, my heart will be uneasy."

　　　　The publication of this book has strengthened Cao’s confidence in taking the road of writing. After the senior high school entrance examination this year, I was admitted to Hefei 28 Middle School with excellent results. From July 20th, he took advantage of the opportunity to look after a relative’s house, and wrote day and night. By August 9th, the sequel of A Feng’s Adventures with more than 100,000 words, A Feng’s Search for Mother, had been finished. After reading this manuscript, Zuo Dunping praised his son and said, "If The Adventures of A Feng is a child’s mental journey, A Feng’s Search for Mother is more mature and his works have more thoughts on reality."

　　　　The person in charge of China Federation of Literary and Art Circles Publishing House called many times after the book was published, saying that Cao Hanyu could go to Beijing if he wanted, and the publishing house would recommend the editing teacher to let him follow the study and creation. This time, Zuo Dunping decided to let his son go to Beijing with sequels, paintings and calligraphy works during the summer vacation, to receive instructions and discuss the publication of the second book. "It’s time for children to go to Beijing to broaden their horizons and accept new thinking." Although The Adventures of A Feng only earned more than 700 yuan in selling sample books in Hefei, Zuo Dunping was very pleased. "My son’s creative path has made me see hope and has enabled me to overcome my illness mentally. I used to sleep in a bed, and my mat was rotten, and my whole body was blistered. Now my blood sugar is under control, and coronary heart disease rarely occurs. I have not been hospitalized this year and my weight has recovered to more than 60 kilograms. I have to thank my son.

　　　　I want to earn money to write a book after school to treat my mother.

　　　　Cao Mengyin was born in a poor peasant family in Jinniu Town, Lujiang County, Anhui Province in 1992. In 1996, his mother Zuo Dunping suffered from hyperglycemia, which delayed medical treatment and caused many complications such as hypertension, coronary heart disease and diabetes. Zuo Dunping became a veritable "medicine jar" at home. In order to facilitate Zuo Dunping’s medical treatment, Cao Jia left his eldest son to his grandmother’s care, moved his youngest son to Hefei, rented it near the south gate, and relied on Cao’s father to work to maintain this family. At the age of 9, Cao Hanyu borrowed from Hefei No.61 Middle School. In 2004, Cao was involved in Hefei No.61 Middle School.

　　　　On December 25th, 2005, 43-year-old Zuo Dunping became ill again. In order to save money, after coming home from the hospital, my mother asked the doctor in the small clinic at the door of the house to help me with the intravenous drip. On that day, I had to hang three bottles of liquid medicine continuously. At that time, there was a bottle of water that my mother used to warm her hands. When it was cold, she put it on the table. The implication of concentrating on reviewing lessons when I was a nurse at home, I didn’t pay attention when I came to help my mother change the potion. I accidentally hung up the bottle of cold water as a medicine bottle. Soon, my mother was sweating and her face was blue, and her breathing was difficult and she was about to go into shock. Implication was so scared that he burst into tears and quickly pulled out the needle. He cried and shouted for help to his neighbor. Three hours later, the mother who was sent to a nearby big hospital for rescue returned to normal. Implication beats his thigh hard with his fist and scolds himself for being useless, which almost hurts his mother. That is, on that cold night in the hospital, Zuo Dunping had the idea of suicide for the first time: my existence would only add insult to injury to this poor and weak family, and the eclipsed life has lost its meaning … "Late at night, Zuo Dunping secretly pulled out the infusion needle and quietly waited for the arrival of death. Mother and son are connected to each other, which means that they found the danger in time. He quickly called the doctor and persuaded her over and over again: "Mom, life is your own. As long as you are willing to fight, no one can take it away. Mom, as long as you have a breath, we are a complete, happy and harmonious family! In 2008, I will also work to earn money to take you to Beijing to watch the Olympics! " Zuo Dunping burst into tears. She rubbed her son’s face over and over again, glad that she had such a filial and sensible son, and gave up the idea of suicide.

　　　　"Dad’s burden is too heavy, and Mom’s mood is too bad. I have to share something for them." Cao Fuyin suddenly remembered that he could earn money by writing novels and help his mother buy medicine, so he said to his mother who was ill at home all day, "Mom, I have felt that I have rich imagination since I was a child. I want to write down these imaginations and write them into a book. Mom, you are in poor health and rarely go out. I want to let these words accompany you after writing, so as to improve your mood." Zuo Dunping didn’t care about his son’s ideas at first, but told him to concentrate on his studies and not to delay his homework.

　　　　Cao Xianyu was afraid of making his mother angry, so he didn’t write novels at home and decided to write them in a loose-leaf book. Every day at school, he secretly tore off the loose-leaf paper and took it to school to write. In the summer vacation of 2006, Cao Yu stayed at home all day and kept writing. For juvenile implication, the biggest cost of writing a novel is time and health. Implication takes more than ten hours to write a novel. Because of excessive use of his eyes, his eyes feel swollen and painful and shed tears. Later, he really couldn’t stand it. He went to a small clinic nearby for medical treatment. The doctor told Implication very seriously that if he continued to work like this, his eyes would be severely nearsighted. After listening to the doctor’s words, Implication didn’t dare to touch the novel for a whole day, but at night, as soon as his brain entered the inner world of the characters in the novel, his hands began to itch, and he couldn’t stop, so he had to turn over and get up.

　　　　That summer vacation, the whole person seems to be in a state of obsession and madness. He eats during the day and thinks about novels. Even sleeping and dreaming at night is also a novel character. He often wakes up in the middle of the night and suddenly thinks of any good words or plots, and immediately takes out papers and notes from under his pillow. Every time I finish a chapter, my mother is always the first reader, and my son’s novels bring infinite joy to my ailing mother. In this way, by August 24 of that year, the manuscript was completed, with 176 pages and 150,000 words. A Feng, the hero of the novel, has taken countless adventures and conquered countless monsters. In order to eliminate the immortal magic, A Feng has honed from a child who knows nothing to a hero who has extraordinary courage and eliminates evil. The plot of the novel is ups and downs, listing all kinds of monsters and demons and all kinds of magic reduction methods, and the imagination is very rich. Inside and outside the book, the same effect is achieved. A Feng’s mother is very great, but she is controlled. A Feng vows to save her mother even if she loses her life. In real life, the sensitive and introverted implication turns into the omnipotent Afeng in the book, galloping freely in the fantasy world, vowing to save his mother. (A Dai)

　　On July 6, experts discussed in front of an intelligent generation painting about Shanghai. On the same day, the 2023 World Artificial Intelligence Conference kicked off at the Shanghai World Expo Center. Xinhua news agency

　　The 2023 World Artificial Intelligence Conference was held in Shanghai from July 6 to 8. The theme of this conference is "Zhilian World Generates the Future". More than 400 exhibitors are exhibiting scientific and technological achievements in the fields of large models, chips, robots and intelligent driving in the main exhibition area of 50,000 square meters of the Expo Exhibition Hall. The number of exhibitors and exhibition area are the highest in history.

　　The conference launched forward-looking discussions on frontier topics such as big model, generative artificial intelligence, scientific intelligence, embodied intelligence and meta-universe, and looked forward to the new form of human civilization after "intellectual change". Lei Jun, the founder of Xiaomi Group, said a few years ago that the past decade is the era of mobile Internet, and the future is the era of intelligent interconnection of all things. "Whoever grasps AI will grasp the future." To this end, all countries and regions have been working on the AI ? ? track in recent years.

　　At present, how is the overall development of AI industry in China? What layouts are being made at the national and local levels? As the venue of WAIC, what position does Shanghai occupy?

　　Global manufacturers rush to the beach AI Blue Ocean

　　Since the beginning of this year, ChatGPT, a chat bot developed by OpenAI, has spread all over the world, which has triggered a wave of competition among technology giants. Baidu ERNIE Bot, Ali Tongyi Qianwen, Tencent Mixed Assistant, JD.COM ChatJD, and Huawei Pangu all came to the end, rushing to the vast blue ocean of artificial intelligence.

　　In fact, language recognition and human-computer interaction are just the tip of the iceberg in the application of AI technology. As Kai-Fu Lee, President and CEO of innovation works, said, AI technology will have a far-reaching impact on finance, manufacturing, education, film and television, entertainment, medical care and many other fields. In reality, artificial intelligence has already spread all over various production scenes, such as the automatic unmanned wharf in Qingdao, the unmanned locomotive in Fankou Mine in Shaoguan, and the research and development of AI innovative drugs in the field of smart medical care.

　　This time, WAIC in Shanghai showed us a broad picture of AI life: competing with AI robots to shoot and play chess, enjoying its creation of paintings and calligraphy on a round fan, and tasting its ground coffee … … It can be said that human beings are entering the "artificial intelligence era". It is believed that before long, it will become an indispensable necessity for human beings like computers, cars and even air and water.

　　It is precisely for this reason that all countries are striving for AI as a key industry with priority development. Among them, not only major economies such as the United States, Britain, the European Union, Japan and South Korea continue to strengthen policy guidance, increase support, and seize the commanding heights of artificial intelligence competition, but some small and medium-sized countries also go all out and even "All in AI".

　　For example, the Danish government released the National Strategy of Artificial Intelligence in March 2019, aiming to make Denmark get the maximum benefit from the huge potential of artificial intelligence. In November of that year, Singapore also released an 11-year national artificial intelligence strategy, and planned to invest 500 million Singapore dollars to promote the application of artificial intelligence technology in five major areas: transportation and logistics, smart cities, medical care, education and security, and strive to complete the intelligent upgrade of national infrastructure in 2030.

　　As for China, in terms of quantity and scale, it has become a big country of artificial intelligence. According to the calculation of China ICT Institute, by the end of 2022, there were 27,255 representative enterprises of artificial intelligence in the world and 4,227 enterprises in China, accounting for about 16% of the world. In 2022, the scale of artificial intelligence core industry in China reached 508 billion yuan, up 18% year-on-year. All these mean that China’s artificial intelligence industry has entered the first gradient in the world, and its industrial scale continues to expand, and its industrial ecology has taken shape.

　　On the other hand, as Mei Jianping, deputy director of the High-tech Department of the Ministry of Science and Technology and a first-class inspector, pointed out at the 2023 Zhongguancun Forum on Artificial Intelligence Open Ecological Construction, China still lags behind the world’s leading level in the fields of underlying algorithms, key software and hardware, and ecosystems. How to narrow this gap and whether we can overtake in corners in the AI field is related to the national movement, which requires the joint cooperation and joint efforts of the state and local governments, science and technology and industry.

　　Who is the first city in domestic AI industry?

　　2016 is known as "the first year of artificial intelligence". That year, AlphaGo, an artificial intelligence robot developed by Google’s team, defeated the Go champion twice, causing a sensation. In May of the same year, the National Development and Reform Commission, the Ministry of Science and Technology, the Ministry of Industry and Information Technology and other departments jointly issued the Implementation Plan of the Three-year Plan of Artificial Intelligence in internet plus, and in July of the following year, the Development Plan of a New Generation of Artificial Intelligence was released. As a result, the domestic AI industry gained more policy and financial support and began to enter the fast lane of development.

　　According to the statistics of China Artificial Intelligence Industry Picture Book, the number of artificial intelligence-related enterprises in China increased from 279,500 to 600,500 in just six years from 2016 to 2022, more than doubling.

　　In terms of geographical distribution, Pearl River Delta, Yangtze River Delta and Beijing have obvious advantages as the three major gathering areas of domestic artificial intelligence industry. Among them, the number of artificial intelligence-related enterprises in Guangdong reached 130,000, ranking first in all provinces and cities, and the total amount was more than twice that of the second place. Since then, 56,582 companies in Jiangsu, 47,793 companies in Beijing, 42,785 companies in Zhejiang and 39,202 companies in Shanghai have formed the head camp of domestic AI industry together with Guangdong.

　　As far as the number of enterprises is concerned, in the past six years, the number of AI-related enterprises in Guangdong, Jiangsu and Zhejiang provinces has grown the fastest, with 95,701, 42,560 and 35,009 newly added respectively. In addition, Shandong, Anhui, Sichuan, Beijing, Shanghai and other provinces and cities have also added more than 20,000.

　　Among them, Beijing, where Baidu and ByteDance are located, said that it would be a "leading city" for artificial intelligence; Shanghai, with Microsoft, IBM, Infineon and other layouts, proposed to speed up the creation of artificial intelligence "Shanghai Highland"; Shenzhen, with Tencent and Huawei, is committed to becoming the "industrial highland" of artificial intelligence … … Then, in this fierce AI industry competition, who is currently leading temporarily, and who can finally reach the top of the first city of artificial intelligence?

　　In terms of the number of enterprises alone, from 2016 to now, the city with the largest number of new AI enterprises is Shenzhen, with 42,598, followed by Guangzhou (29,922) and Beijing (21,483). Therefore, Shenzhen has become the first city in the national artificial intelligence "density" with the total number of 63,800 AI-related enterprises. However, the advantages of Shenzhen are mainly concentrated in the downstream of the AI industrial chain. Although the scale and innovation of the industrial chain are leading the country, there are insufficient financing and growth.

　　According to the data of China Artificial Intelligence Industry Illustrated, during the period from 2016 to 2022, the top five cities in total financing amount of AI-related enterprises were: Beijing (6,716.182 billion), Shanghai (4,355.743 billion), Shenzhen (2,706.635 billion), Hangzhou (1,769.097 billion) and Nanjing (8,036.44).

　　Generally speaking, the AI industry in all parts of China is still in the stage of letting a hundred flowers blossom and competing with each other, and the winner has not yet been decided, which also gives opportunities for all localities to catch up and catch up with each other.

　　Shanghai’s AI industry ambition

　　Just the afternoon before the opening of the 2023 World Artificial Intelligence Conference, a high-level expert meeting on artificial intelligence strategy consultation attended by both the secretary of the municipal party committee and the mayor was held in Shanghai, which showed the importance attached to the future development of the AI industry and the "Shanghai as a universal artificial intelligence".

　　Subsequently, Wu Qing, member of the Standing Committee of Shanghai Municipal Committee and executive deputy mayor, attended the AI+ Industry-Finance Collaborative Development Forum in Wisdom and delivered a speech, which directly declared the ambition of Shanghai’s AI industry: Shanghai regards artificial intelligence as one of the three leading industries and accelerates the creation of artificial intelligence "Shanghai Highland".

　　Shanghai is emboldened to say so. At present, the number of AI enterprises above designated size in Shanghai has reached 350, almost doubling in the past five years; The output value reached more than 380 billion yuan, almost three times that of five years ago; The number of industrial talents has reached 230,000, accounting for about one-third of the country.

　　The achievement of these achievements is inseparable from Shanghai’s early planning and long-term layout of artificial intelligence. As early as 2017, Shanghai issued the "Implementation Opinions on Promoting the Development of a New Generation of Artificial Intelligence in this Municipality", which made AI a priority development strategy for Shanghai for the first time. Since then, the Implementation Measures for Accelerating the High-quality Development of Artificial Intelligence, the Action Plan for Building an Artificial Intelligence Shanghai Highland and Building a First-class Innovative Ecology (2019-2021) and the Tenth Five-Year Plan for the Development of Artificial Intelligence Industry in Shanghai have been successively formulated.

　　On September 22, 2022, the Regulations of Shanghai Municipality on Promoting the Development of Artificial Intelligence Industry was officially promulgated, which is also the first provincial-level local regulation in the field of artificial intelligence in China.

　　In terms of organizational guarantee, Shanghai has established a leading group for artificial intelligence industry work and a Shanghai artificial intelligence strategic consulting expert Committee; In terms of resource integration, Shanghai has built the country’s first pilot zone for innovative application of artificial intelligence and the national experimental zone for innovative development of new generation artificial intelligence; In terms of ecosystem, Shanghai has successively established the municipal artificial intelligence industry association, the global academic alliance of artificial intelligence in colleges and universities, the alliance of young AI scientists and other industry organizations.

　　At the same time, Shanghai attaches great importance to giving full play to its advantages as an international financial center and providing a steady stream of living water for the development of the AI industry.

When it comes to the Dragon Boat Festival, many people first think of "eating zongzi" or "dragon boat racing". But in fact, in addition to these traditional customs,It also contains an extremely precious concept of public health and epidemic prevention.

Mulan decoction, spraying realgar and avoiding the intrusion of "five poisons" all reflect the ancient people’s super-strong awareness of disease prevention.It can be said that the Dragon Boat Festival is a veritable "public health and epidemic prevention festival".

Dragon boat festival "expelling drugs" The custom was formed before Qu Yuan’s time.

According to the existing literature and historical data, the Dragon Boat Festival custom was formed much earlier than that of Gou Jian, Wu Zixu and Qu Yuan, and its original cultural meaning should be the custom and ceremony of the ancients to send disasters, eliminate evil spirits and drive away epidemics, and it is a kind of "public health" activity on the folk level.

The reason why people attach so much importance to these activities is inseparable from the characteristics of the Dragon Boat Festival. At this time, the weather is getting hotter, rainy and humid, and people are prone to get sick. In addition, snakes and insects breed and bite people easily. There was a folk song that said:"Dragon Boat Festival, the weather is hot, the five poisons wake up, and it is not peaceful."

It means that since the Dragon Boat Festival, the "five poisons" began to breed, disturbing people. The "five poisons" mentioned here are the five animals that people thought were poisonous in ancient times: snakes, scorpions, centipedes, geckos and toads. In order to avoid the intrusion of poisonous insects, people try their best, so various customs of "expelling poisonous insects" have been formed among the people.

Dragon Boat Festival: the earliest "Medical and Health Festival" in China

Folklore experts said that judging from these customs, the Dragon Boat Festival can be regarded as the earliest "medical and health care festival" in China and the earliest public health festival in China. There have been many changes in the ancient customs, but what remains unchanged is people’s longing for a better life.

Dragon boat race is also a "disaster-fighting" ceremony.

So how do people do it?

Expel foul gas:Usually, people will be in the corners and shadows.Sprinkle lime, spray realgar wine and burn medicinal smoke to eliminate the "five poisons" and drive away foul gas.

Stick a map of five poisons:At the same time, it is also necessary to put up a map of five poisons in the house, especially embroidered with five poisons on children’s shoes, clothes and Chinese-style stomachs.

Dragon boat race "disaster":Many people may not know that dragon boat racing is actually a kind of "disaster-stricken" ceremony, which was originally regarded as "Send a disaster to send a plague boat ",Entrust people’s wishes for good luck and health.

In addition, there areCollecting herbs, hanging wormwood and Mulan decoctionAnd so on. Custom activities.

-Excerpted from [Song] Su Shi’s "Liu Yao Ling Tian Zhong Festival"

Willows are inserted in Qingming Festival, and wormwood is inserted in Dragon Boat Festival.

Every Dragon Boat Festival, people will insert wormwood into the lintel, or cut wormwood into the shape of a tiger and hang it on the door, calling it "Ai Hu". Many places also use mugwort leaves to soak in water and take a bath.

During the Dragon Boat Festival, the temperature rises, which is the period of frequent diseases. The special fragrance of wormwood can be used to prevent mosquitoes and repel insects.

Don’t talk about the past. A thousand years of loyalty and loyalty, the sun shines. It always hurts to read Li Sao. No one can solve it, and the tree turns cool in the afternoon.

"Holding the moxa flag to attract a hundred blessings, hanging a sword on the door to kill a thousand evils", wormwood and calamus can be said to be the main plants of the Dragon Boat Festival.

Like wormwood, people hang calamus to ward off evil spirits and charm. The leaves of Acorus calamus are sword-shaped, symbolizing driving away ominous swords, and later extended to "Pu Jian" that can cut thousands of evils. Some places not only hang calamus on the Dragon Boat Festival, but also drink calamus wine.

Acorus calamus is mostly born in swamps and watersides, and is called "four elegant flowers and plants" with orchids, daffodils and chrysanthemums. The ancients thought that Acorus calamus was bitter and cold-resistant, peaceful and indifferent, not holiday-colored, not rich in land, elegant and handsome, tall and straight as a garden, with the atmosphere of a mountain forest and no wealth.

There is a saying in the farmer’s proverb: "Don’t eat garlic at the Dragon Boat Festival, and the ghost will get in front of the door." In ancient times, the Dragon Boat Festival was a period of high incidence of epidemics. It is said that eating garlic can dispel "poison". Therefore, some places still have the custom of eating garlic.

This gave birth to many ways to eat:

For example, tofu stewed with garlic is smooth and delicious;

For another example, put garlic, eggs and wormwood in clear water and cook them. The garlic after taking out the pot has the fragrance of wormwood, and the entrance is soft, glutinous and spicy;

For example, peel and wash garlic, sprinkle brown sugar and steam it, then pour a spoonful of sesame oil, which has a unique taste.

Dragon Boat Festival is the time when pomegranate blossoms. In some areas of our country, people are used to hanging pomegranate flowers during the Dragon Boat Festival instead of wormwood and calamus.

There is a saying that the ancients used Acorus calamus, Folium Artemisiae Argyi, Pomegranate Flower, Garlic and Dragon Boat Flower to control the "five poisons" of the Dragon Boat Festival. These five plants are collectively called "five ruies in the sky".

Gu Lu’s "Qing Jia Lu Dragon Boat Festival" records: "The fifth day, commonly known as the Dragon Boat Festival. Bottles are for hollyhock, pomegranate, cattail and other things, and women’s mugwort leaves and pomegranate flowers are numbered’ Dragon Boat Festival Scene’. " Therefore, in some parts of northern China, on the Dragon Boat Festival, the elderly should put a pomegranate flower on their children’s heads to pray for their safety and wealth.

Moreover, hollyhock blooms before and after the Dragon Boat Festival, and it has the effect of clearing heat and detoxifying, so some people are also called "Dragon Boat Festival Flower".

Also busy with the medicine and prescription, for this year can be safe and ill.

Having finished these, it was the sun and the west, when the family had prepared the food and drink, and he was glad to drink the wine.

Although the leaves used for making zongzi vary greatly from place to place, most of them have the characteristics of more fiber, corrosion resistance, boiling resistance and fragrance.

The common zongzi leaves are reed leaves, Indocalamus leaves and Hiragi leaves.

Reed leaves are usually slender.

▲ The picture comes from the network.

Indocalamus leaves are widely used in the south. Ruo is a kind of bamboo, and Ruo leaves are Ruo leaves. Indocalamus leaves are not as slender as reed leaves, but usually wider, which is suitable for making triangular and quadrangular zongzi.

Hiragi has large leaves, which are suitable for making zongzi. For example, Hainan’s special zongzi is made of Hiragi leaves, stuffed with squid, shrimp, salted egg yolk, barbecued pork, etc. It is big, and some of them are about half a kilogram, which can provide an adult with a full meal. Hiragi leaves are big, as you can see from the picture.

Mulan Festival in Poetry

Huanxisha Dragon Boat Festival

The light sweat slightly penetrated Bi Wan, and the Ming Dynasty Dragon Boat Festival bathed Fang Lan. Qing Chuan is full of fragrance.

The colored thread is lightly wrapped around the red jade arm, and the small character hangs obliquely on the Lv Yun. Beautiful women meet for a thousand years.

Dragon Boat Festival is also known as Mulan Festival. In ancient times, there was a custom of medicated bath in Dragon Boat Festival. Pine, cypress, mulberry twig, mugwort leaf and other herbs were boiled into juice and bathed in it to prevent epidemic and strengthen the body. This herbal water is "Mulan Decoction".

It should be noted that the "orchid" here does not refer to orchids, but to Eupatorium odoratum or herbs of Compositae, which has fragrance and can be decocted and bathed. Qu Yuan’s "Nine Songs in the Cloud" also contains the sentence of "Bathing orchid soup and enjoying fragrance".

There is also the custom of wearing sachets during the Dragon Boat Festival. The sachet is filled with a variety of plant medicinal materials, with fresh fragrance, and has the effects of eliminating moisture, refreshing the brain and expelling mosquitoes.

▲ The Spring Dawn of the Han Palace was partly painted by Chou Ying in the Ming Dynasty. In the picture, the woman is sitting around and fighting grass. The picture is from Forbidden City magazine.

On the day of the Dragon Boat Festival, participants in grass fighting went out to find some exotic flowers and plants to compete with each other. There are two main forms of fighting grass:

One can be called a literary fight, in which the names of flowers and grasses are reported to each other in the form of antithesis, and most of them win. This is not only better than the collection of flowers and plants, but also the accumulation of plant knowledge and literary knowledge on both sides.

The other is called warfare, in which the participants hold the grass opposite each other, and each person holds one end of a grass (or flower) stem in both hands, hooks it with the grass stem in the other hand, and pulls it hard. Whoever pulls the grass stem is the loser.

In fact, fighting grass is a game derived from picking herbs. The Dragon Boat Festival is considered to be the best time to collect herbs, and there is a folk saying that "before the Dragon Boat Festival, there is grass, and when it comes to the Dragon Boat Festival, it becomes medicine".

Plants occupy an important position in the Dragon Boat Festival:

People draw materials from nature,

Wrapping zongzi with reed leaves and Indocalamus leaves,

Hanging mugwort leaves and calamus at the door,

Sprinkle the courtyard with plants dipped in realgar wine,

Pomegranate flower,

Mulan decoction,

Wearing a sachet,

Go up the mountain to collect medicine,

……

All these have pinned the expectation of epidemic prevention and health care.

One last reminder:

Cherry is undoubtedly one of the most "hot" fruits, with bright color, juicy, sweet and refreshing taste, which is deeply loved by many people. Many people are curious, what is the relationship between cherry and cherry? Can you supplement iron and vitamin C? In this issue, I will tell you some truths about cherries.

Truth 1: Cherry is a kind of cherry.The cherries we usually eat are divided into China cherry, European sweet cherry and European sour cherry. The round and bright red cherries sold in the market are usually European sweet cherries. In fact, cherries are a variety of sweet cherries in Europe, and the name comes from the transliteration of cherry. European sweet cherries landed in China in the 1980s. They were first cultivated near Yantai, Shandong Province, and then gradually developed. Their appearance and taste are very good, and they are not inferior to those imported. According to statistics, the planting area of sweet cherry in China accounts for about 17% of the world total area, and the output accounts for about 10% of the world total output.

Truth 2: It is difficult to make up iron by eating cherries.Although cherries are ruddy in color, their iron content is not high. The data shows that the iron content of cherries is only 0.36 mg /100 g, while the iron content of lean pork we usually eat is 3 mg /100 g. Moreover, the iron in cherries is plant iron, that is, non-heme iron, and its absorption and utilization rate is very low. Cherry blood is more like a legend of "supplementing shape with shape" So far, no substance that can promote blood production has been found in cherries. Therefore, it is not reliable to supplement iron by eating cherries. It is better to eat two bites of lean pork.

Truth 3: The vitamin C content of cherries is not high.The vitamin C content of cherries is only 7 mg /100 g, which is only about 1/5 of that of oranges (33 mg /100 g) and far lower than that of kiwis, strawberries and fresh dates. In terms of nutrition, cherries are rich in dietary fiber and potassium. The potassium content of cherries is 222 mg /100 g, which is close to that of bananas (256 mg /100 g). However, the calories of cherries (63 kcal/100g) are lower than those of bananas (93 kcal/100g). If you want to supplement potassium and eat as little calories as possible, cherries are more suitable. To many people’s surprise, the dietary fiber content of cherries with refreshing taste exceeds 2%, which is higher than that of many vegetables with rough taste. Dietary fiber can promote intestinal health, and people with constipation may wish to eat cherries often.

Truth 4: Eating too many cherries will lead to black stool.Cherry contains anthocyanin, which is a kind of polyphenol compound, mainly anthocyanin, which has antioxidant effect, can prevent cardiovascular diseases, scavenge free radicals, delay aging and resist inflammation. The more ruddy the cherry, the higher the anthocyanin content, and the higher the content, it will appear red or even black. However, this ingredient cannot be absorbed and metabolized by the human body, and can only be directly discharged. The content of anthocyanin in cherries is 15~50 times that of strawberries. Therefore, if you eat too many cherries and take too many anthocyanins at a time, your stool will be black or your urine will be red. This change is not harmful to health. When anthocyanins are metabolized, they will return to normal.

Truth 5: Sugar lovers and people who lose weight can eat cherries.Although cherries are sweet and fragrant, the glycemic index is only 22, which is lower than most fruits such as apples (36), pears (36) and grapes (43). This is probably because the content of polyphenols such as anthocyanins is high, which inhibits the activity of digestive enzymes, and the content of pectin is also high, which delays the digestion and absorption of sugar. Therefore, cherries are very suitable for people with hyperglycemia. The data shows that the moisture content of cherries exceeds 80%, which makes its calorie low, 63 kcal /100 g, which is similar to that of apples, so it is very suitable for people who lose weight.

Truth 6: Eating cherries won’t cause poisoning.There are indeed cyanosides in the stone of cherries, which will be decomposed to produce hydrocyanic acid, and the cyanosides will combine with the iron ions of oxidase in cytochrome, thus causing obstacles in tissue respiration and even suffocation. In people, it is often manifested as bitterness in the mouth, dizziness, headache, vomiting, palpitation, weakness of limbs and even difficulty in breathing. However, few people will bite the stone when eating cherries, and acute poisoning symptoms will only appear when cyanosides reach a certain amount. There is no problem in eating cherries normally.

Truth 7.: The more "J", the bigger the cherry.J(jumbo) is a commonly used unit for cherry grading in the southern hemisphere, which is usually used in Chile, New Zealand and other places. Generally speaking, the fruit diameter of 26~28 mm is J, that of 28~30 mm is JJ, that of 30~32 mm is JJJ, that of 32~34 mm is JJJJ, and that of 34 mm or more is JJJJ. The bigger the fruit diameter, the higher the grade and the more expensive the price. You can choose according to your needs.

How to choose cherries? First, look at the fruit stalks. Fresh cherries are green and have high hardness. If the fruit stalks are seriously black and soft to the touch, they are not fresh. Secondly, in terms of shape, the belly of cherries with good quality is full, round and smooth. If there are many wrinkles on the surface, it means that cherries are dehydrated. Third, distinguish colors. Dark colors taste sweeter, while light colors tend to sour. The cherries bought home can’t be eaten on the same day, so seal them with fresh-keeping bags and put them in the refrigerator.
