　　Xinhua News Agency, Guiyang, July 3 rd Title: Revealing the world’s largest "pot cover": 4,450 reflection units spell out the world’s largest and strongest "Eye of the Sky"

　　Xinhua news agency reporter

　　Remember what the "pot cover antenna" looks like?

　　On July 3, 2016, the world’s largest "pot cover" with a diameter of 500 meters was erected in Guizhou karst tiankeng.

　　It is the 500-meter spherical radio telescope, the largest and most powerful single-aperture radio telescope in the world.

　　It is called "Eye of the Sky", which is used to listen to the sounds in the depths of the universe and observe the mysteries of the universe.

　　Start with Xue Huadian on old TV.

　　When the old TV can’t receive the signal, the screen is not blank, but Xue Huadian is flashing. In fact, these Xue Huadian are electromagnetic wave signals, including radio emission from space.

　　In 1933, scientists in bell laboratory accidentally discovered the stable radio emission from the center of the Milky Way with a highly sensitive receiver, which opened the door to radio astronomy.

　　Anyone who has used the "lid antenna" knows that the larger the lid aperture, the clearer the TV picture. For radio telescopes, the larger the aperture, the farther you can see. Radio astronomers all over the world are pursuing to build a larger-caliber "pot cover" to improve the sensitivity of radio telescopes.

　　Peng bo, a researcher at the National Astronomical Observatory of the Chinese Academy of Sciences and deputy manager of the 500-meter spherical radio telescope project, said that the radio telescope had been short of funds at the beginning of its design and construction, but scientists were unwilling to reduce its caliber no matter what it was reduced.

　　"Space is mixed with all kinds of radiation, and distant signals are like cicadas in thunder, and there is no super-sensitive ‘ Ear ’ I can’t tell it at all. " Nan Rendong, chief scientist and chief engineer of the 500-meter spherical radio telescope project at the National Astronomical Observatory of the Chinese Academy of Sciences, said.

　　Previously, the most sensitive radio telescopes in the world were the 100-meter telescope in Bonn, Germany and the 300-meter telescope in Arecibo, USA. The former can move and "shake its head", while the latter is built with the help of karst potholes on Puerto Rico island.

　　At the 1993 International Radio Union Congress, astronomers from 10 countries, including China, proposed to build a new generation of radio "big telescopes", eager to go back to the original universe and solve many difficult problems in astronomy before the radio wave environment was completely destroyed.

　　"Building the world’s first large-caliber radio telescope is the dream of teacher Nan Rendong and several predecessors, which embodies the ambitious ambition of China astronomers." Peng bo said.

　　At the end of 1995, more than 20 universities and research institutes in the United Nations of Beijing Observatory set up the China Promotion Committee of Radio "Large Telescope", and put forward the karst engineering concept of building a spherical reflector, namely "Arecibo antenna array", by using Guizhou karst depression.

　　Since then, scientists in China have further promoted the concept of karst and proposed to independently develop a new karst unit, namely a 500-meter spherical radio telescope.

　　In order to set up a new generation of radio "big telescopes", scientists have turned over the karst mountain areas in Guizhou through satellite remote sensing. Peng bo recalled that at that time, the Observatory commissioned two institutes to conduct independent search and select from more than 300 candidate potholes. As a result, Dawodang, located in Pingtang County, Qiannan Prefecture, got the highest score twice.

　　The conditions provided by natural karst potholes in Guizhou have always been the most unique and the largest and strongest foundation for China Radio Telescope in the world.

　　Not just a big circle — — What is the strength of China Radio Telescope?

　　Whether you are near a large radio telescope, climbing the observation deck on a nearby hill or watching a virtual reality video, you can intuitively feel its first feature — — Big. Scientists describe it as a "giant eye for watching the sky".

　　Wang Qiming, chief engineer of the 500-meter spherical radio telescope project at the National Astronomical Observatory of Chinese Academy of Sciences, said that more than 10,000 tons of steel were used only for the ring beam, cable net and six towers supporting the feed cabin.

　　"The total reflecting surface of the telescope is 250,000 square meters, which is equivalent to the size of 30 standard football fields. Although the reflective panel is only 1 mm thick, it also uses more than 2,000 tons of aluminum alloy. " Wang Qiming said.

　　However, the large radio telescope is by no means a "stupid" metal pile, it is the most sophisticated astronomical instrument. Due to the adoption of the feed platform with optical, mechanical and electrical integration and the secondary adjustment of the parallel robot in the feed cabin, it can realize millimeter-level pointing tracking without rigid connection between the feed and the reflecting surface, ensuring accurate gathering and monitoring of weak radio signals in the universe.

　　The construction technology of the large radio telescope is also improving. Wang Qiming said that due to strict requirements, this big scientific project has promoted the improvement of equipment manufacturing capabilities in many fields:

　　— — The cable net with active reflection surface has the characteristics of high elasticity, tensile resistance and fatigue resistance, and its ultra-high stress amplitude of 500 MPa is 2.5 times that of the national standard;

　　— — More than 2,000 hydraulic actuators that help the reflector to be displaced can achieve accurate positioning and coordinated movement through expansion and contraction, and can also report their own state information to the control system to meet the movement requirements such as timely tracking and source change.

　　— — Dynamic optical cable, which undertakes the mission of transmitting all kinds of data and information, can withstand repeated bending, winding and torsion and other mechanical properties and harsh natural environment tests.

　　"Our original design concept originated from the Arecibo telescope in the United States. But compared with Arecibo, the active reflector system is our biggest innovation. " Peng bo said that the cable net structure of a large radio telescope can change with the movement of celestial bodies, driving 4,450 reflecting units on the cable net to form a 300-meter instantaneous paraboloid in the direction of radio power supply, which greatly improves the observation efficiency.

　　Arecibo telescope is a fixed telescope, which can only scan a 20-degree strip area in the sky by changing the position of antenna collapse. The active reflector allows the China Radio Telescope to have a wider observation range, covering 40-degree zenith angle.

　　The working frequency of large radio telescopes is relatively wide. Peng bo said that the feed cabin is equipped with a multi-band and multi-beam feed and receiver system covering the frequency of 70 MHz ~ 3 GHz.

　　Zheng Xiaonian, deputy director of the National Astronomical Observatory of the Chinese Academy of Sciences, said that the German Bonn telescope with a diameter of 100 meters was once called "the largest machine on the ground", and the sensitivity of the China Radio Telescope was improved by about 10 times. The 300-meter-caliber Arecibo telescope in the United States has been unsurpassed for more than 50 years. Compared with it, the comprehensive performance of China Radio Telescope has been improved by about 10 times.

　　Take root in the karst sinkhole and look at the deep space of the universe

　　"Like other radio telescopes, the two main scientific goals of the China Radio Telescope are to patrol the neutral hydrogen in the universe and observe pulsars. The former is to study the large-scale physics of the universe to explore the origin and evolution of the universe, and the latter is to study the material structure and physical laws in extreme States." Zheng Xiaonian said.

　　The earth’s atmosphere leaves two windows for human beings to explore the universe, one is optics and the other is radio. For astronomers, if the optical telescope is a microscope, then the radio telescope is a CT machine, which can obtain the ultra-fine structure of celestial bodies.

　　"There are seven sets of receivers, because the frequency of observation in different bands is different, and the observation and research goals are different." Peng bo said that in the eyes of large radio telescopes, the universe and cosmic celestial bodies are a three-dimensional presentation.

　　For more than half a century, the energy collected by all radio telescopes in the world has not turned a page, and the joining of China Radio Telescope will greatly accelerate this speed. And the energy collected means the amount of information to interpret the mysteries in the depths of the universe.

　　"Since the birth of the radio telescope, humans have discovered about 2,500 pulsars. If the working hours of the China Radio Telescope are all used to observe pulsars, it is expected to double this number within one year." Peng bo said that pulsars can be used for pulsar navigation, pulsar timing array and other application targets.

　　Nan Rendong believes that large radio telescopes may also find some unprecedented pulsar phenomena, such as a pulsar paired with a black hole, which may produce a breakthrough theory.

　　Every little progress in the development of physics is accompanied by great difficulties and twists and turns. But at every stage of human civilization progress, physics has always stood at the forefront of liberating productive forces. Peng bo said that scientists used Arecibo telescope to discover gravitational waves and won the Nobel Prize in physics, while China Radio Telescope provided a great opportunity for natural science, especially physics-related fields.

　　"The answer is yes to whether the large radio telescope that the public is very concerned about can be used to find extraterrestrial civilization." Peng bo said that it is a weapon to detect exoplanets, especially terrestrial planets. Because of its improved sensitivity, it can see farther and fainter celestial bodies. By detecting interstellar molecules and searching for possible interstellar communication signals, the probability of finding extraterrestrial civilization is 5 to 10 times higher than that of existing equipment.

　　On July 3rd, after the installation of the feed cabin and the reflector panel was completed as planned, the large radio telescope will be debugged for more than two months, and it will be officially completed and put into use at the end of September. However, in order to optimize all functional parameters, it needs to be continuously debugged and improved in two or three years of observation.

　　"After the completion of the large radio telescope, it will become the ‘ Sharp weapon ’ To maintain the status of world-class equipment in the next 10 to 20 years. " Zheng Xiaonian said, "I hope that China scientists will use it to produce results as soon as possible." (Note holder Qi Jian; Participating reporters Wu Jingjing, Hu Xing and Yang Weihan)

Special feature of 1905 film network There is a Chaoyang Road in Beijing, and it is also the place where many young people’s dreams of "drifting north" begin.The hit drama "All the way to Chaoyang" starts from here and tells the story of two post-80 s girls Li Mujia (Landy Li Decoration) and Tian Rong (Naomi Struggled all the way in Beijing, experienced the ups and downs of career, love and friendship, and finally found the story of the heart.

Since its launch, the drama has gained a lot of praise with its sense of realism and substitution, and it has been frequently searched by hot users. The popularity in the station is nearly 9,000, and the sweet interaction between Landy Li and Wang Yang’s "Mu Guang City CP" has also kept netizens on the top.

How to make the story of North drift laugh with tears, real and sensible, and make the age difference CP sweet and new? In 1905, the film network interviewed Yan Jin, the producer of All the Way to Chaoyang, and Lan Xiaoxi, the screenwriter, to reveal the behind-the-scenes story of the crew’s "Walking to the Sun".

"I hope everyone can see their own shadow."

Olympic signs all over the street, CBD building under construction, and hot real estate market, the opening of "All the way to Chaoyang" will bring us back to the hot era before and after the 2008 Beijing Olympic Games.

The time span of the drama is from 2007 to 2019. The two heroines, Li Mujia and Tian Rong, support each other and struggle for progress, which also reflects the style of the whole era.

Screenwriter Lan Xiaoxi interprets it this way: "In the context of the rapid development of the country, everyone is full of vigorous and uplifting temperament, full of power to break through the soil like grass, and we want to convey this tension. Show the ordinary people who are struggling in the great era, and hope that everyone can see their own shadow in the protagonist. "

In the face of such a realistic work, producer Yan Jin’s primary requirement for the crew is "truthfulness" and refines it to every link of the play: not only to restore the scenery of Beijing more than ten years ago in the setting props, but also to strive for truth in the details of the workplace and life.

In the process of writing the script, Lan Xiaoxi and his team went deep into law firms and real estate companies to experience life. After running with lawyers and intermediaries, they accumulated a lot of first-hand materials, and also specially consulted the specific information of various real estate projects in Beijing in that year, from the name to the price.

It is in this way that "All the way to Chaoyang" has the real texture that the audience relishes. It is as small as the suitcase prepared at any time under the station, the business lunch that can’t afford nearly 100 yuan, and all kinds of wonderful things when renting a house. It is as big as the difficulty for graduates from non-prestigious schools to enter well-known companies, the difficulty of being promoted step by step from "post-it notes" assistants, and the bitterness and anxiety in the process of buying and selling houses, all of which make young people who have been or are wandering in big cities feel the same.

"Adults struggle in the workplace with lofty aspirations and a chicken feather, so when we do the drama, we do not avoid these difficulties, but strive to present a real workplace picture and portray a three-dimensional and vivid image of young people, hoping that the audience can find themselves or people around them from it," producer Yan Jin said.

"The love between Li Mujia and Li Guang is evenly matched."

There is not only a real workplace, but also romantic love in "All the way to Chaoyang".

When Li Guang, who has a successful career, meets Li Mujia, a rookie lawyer, facing the gap between age and status, the audience thought that the plot would be staged according to the traditional "overbearing president", but unexpectedly, the president became the "humble" party in his feelings, guarding carefully, being depressed and jealous, taking the initiative to confess, and all kinds of anti-routine dramas kept netizens on going to the top, and also made "the city of Mu Guang CP" a frequent visitor to hot search.

In the view of the two masters, the chemical reaction of "Mu Guang City" is closely related to face-to-face casting and actor acting. Screenwriter Lan Xiaoyu said that when writing the script, she was worried that Li Mujia’s people were too strong and aggressive and not pleasing enough, but Landy Li’s performance completely exceeded her expectations. "There is a gentle and firm power in her innocence."

Producer Yan Jin also thinks that Landy Li and Li Mujia are highly compatible: "The first time we met, I thought she was Li Mujia. Because Landy Li has a lot of fresh and smart temperament, just like a small sun, which can illuminate people around her. At the same time, her heart is also very strong, energetic, ambitious and tenacious. "

On the other hand, Wang Yang, who plays Li Guang, is also the best candidate in the creative mind. Wang Yang, who has been frequently selected as a "uncle circle dish", is full of personal charm, and this time he will also perform a different taste for the overbearing president.

"Teacher Wang Yang has a rich level in performance, not to mention the appearance, which is very attractive. "Yan Jin said:" He interpreted the three-dimensional face of Li Guang, with the domineering of the president, his persistence in architectural ideals and great pressure. His fragile side was seen and comforted by Li Mujia. Therefore, although they have an age gap, they are emotionally evenly matched. "

Many people describe Li Guang and Li Mujia as a combination of "a fox and a white rabbit", but the screenwriter Lan Xiaoxi said that they met a little fox after all. "The reason why Li Guang was attracted to Li Mujia is precisely because Li Mujia has many similarities with him, that kind of persistence and stubbornness, that kind of impulse to gamble for his own ideals, and they are very similar in essence."

Looking for weaknesses in the president, and then presenting a close, equal and sincere love is the creative rule of the founders. "Good love really has nothing to do with age, but whether it is sincere."

"Women’s mutual help does not need to be deliberately designed"

If Li Guang is a beam of light that illuminates Li Mujia’s life, Tian Rong, a good friend played by Naomi, and Wu Jianqiu, a boss played by Gao Ye, are also indispensable partners on the road to "Xiangyang". These female characters never give up when they are in trouble and protect each other, which also adds a touch of bright and warm color to the drama.

In the main creative view, compared with Li Mujia’s sparkling, Tian Rong is an ordinary girl who is more grounded, and it is easy for the audience to substitute and resonate. "Tian Rong is not perfect, but her indomitable quality and true nature of daring to love, hate and break in feelings will make the audience like and empathize."

Talking about the intimate relationship between Li Mujia and Tian Rong, Yan Jin said that they are both "sisters" and "comrades-in-arms". "They had quarrels, but there was no dog blood. They laughed and wept, and they still cared about each other in the quarrel and reconciliation. You have me, I have you, and each other has become the most beautiful scenery in each other’s growth. "

Tian Rong is a colleague, and Wu Jianqiu is more like a "guide". Gao Ye, an actress, once again created a powerful and charming image of a "big woman" after "eldest sister-in-law". The two masters were full of praise for her performance. Lan Xiaoxi commented: "Wu Jianqiu’s free and easy domineering temperament, daring to love and hate, is very suitable for her. Sometimes she doesn’t need lines, and a look is in place."

For the popular theme of "women helping each other", Yan Jin and Lan Xiaoxi believe that it should not be a deliberately designed plot, and it does not need chicken soup and dog blood. "Showing the relationship of mutual support between women in reality will definitely arouse the audience’s resonance."

"All the way to the sunrise, walking towards the light", the film title "All the way to the sunrise" also implies the creative initial intention of the two masters, regardless of prosperity and adversity, they must maintain the posture of being born in the sun. Yan Jin said: "Although lying flat is popular now, I don’t think everyone is willing to be flat. No matter what era we are in, we must live well and take our lives seriously.

Or, as the lines written by Lan Xiaoxi for Li Mujia said: "Along the way, all the merits are rewards, and all the pits are experiences. On the road of life, no matter whether you choose left or right, you will buy and leave your hand. If you don’t care about your wrong love, ride forward, and the light will definitely be at the dark end."

　　Since 2006, ACSM (American Sports Medicine Association), as one of the most authoritative organizations in global sports science, will release the global popular fitness programs in the coming year at the end of each year, and the publication of the 2020 edition of the Global Fitness Trend Report is also the 14th release of the report. Not long ago, Shanghai Institute of Physical Education and ACSM jointly released "China Fitness Trend in 2020", which also listed 20 most potential training methods in the new year. After listing the global and China fitness trends, we found that the trend rankings are not the same, and it can also reflect the uniqueness of the fitness market in China. Let’s take a look at the changes of fitness trends in China and compare them with the global fitness trends.

　　Analysis of Fitness Trend in China in 2020

　　The top three fitness trends in China in 2020 are weight loss exercise, youth sports and sports are good doctors/medicines. It can be seen that the Chinese people’s enthusiasm for weight loss has not diminished, and youth sports have warmed up rapidly. At the same time, it reflects the improvement of national requirements for their own shape and health and the strengthening of attention to youth sports.

　　TOP1 weight loss exercise

　　Weight loss exercise is mainly a multi-category integrated exercise and fitness method for the purpose of weight loss. Weight-loss movement jumped from 19th place in China fitness trend in 2018 to 2nd place in 2019 and 1st place in 2020, which shows that the domestic fitness industry pays attention to overweight and obese people and the national demand and attention to weight control.

　　TOP2 Youth Sports

　　Youth sports mainly refers to the fitness exercise aimed at improving the health level of young people through learning and exercising sports skills. Youth sports ranked third in 2018 and sixth in 2019. At present, the obesity rate of adolescents remains high, and the younger age of diseases is the main reason for this trend. Experts said: "China’s current health literacy is low, and health weight loss education needs the joint publicity and guidance of society, parents and schools to achieve effective results. In terms of sports, the gym is not open to young people, so where do young people go to exercise? This problem needs to be solved. Youth sports are not limited to schools, but also to the society. "

　　TOP3 exercise is a good doctor/medicine

　　Exercise is a good doctor, which is a global health initiative. It aims to encourage medical staff to increase physical activity examination and get advice and guidance from sports professionals when formulating disease treatment programs. This trend entered the top 20 fitness trends in China for the first time, and jumped to the third place. In the past two years, this trend only ranked 21st and 29th. Under the general trend of the integration of sports and medicine, people in the domestic health and fitness industry have more deeply felt the important role of sports in health promotion, and have been more and more recognized by the people.

　　Compared with the fitness trend in China in 2019, the fitness trend in the top 20 in 2020 is that the third-ranked sports are good doctors, the fifth-ranked fitness diet, the 11th-ranked mobile device sports App, the 13th-ranked wearable device, the 14th-ranked exercise intervention for obese teenagers, the 16th-ranked free weight training and the 19th-ranked brisk walking. Mobile device sports App, wearable device, exercise intervention for obese children and walking briskly returned to the list after falling out of the top 20 last year. Among them, the trend of weight loss movement has reached the top, reflecting the increasing demand for weight loss in China, and weight loss has become the first need. In addition, the square dance has risen sharply in the ranking of sports and fitness trends in China, which also reflects the distinctive features of the fitness situation in China.

　　China fitness trend VS global fitness trend in 2020

　　Compared with the global fitness trends in the past 20 years, there are 9 same trends in China and the world. Generally speaking, there are obvious differences in trends and rankings. For example, the employment of professional certified fitness experts and professional fitness licenses in the global fitness trend is not reflected in the fitness trend in China. Although the demand for private education and group class coaches is increasing in the fitness trend in China, it seems that the professional training of coaches is still not paid enough attention.

　　Among the top 20 trends in the world, free weight training ranked 4th, life medicine ranked 16th, cycle training ranked 17th (ranked 21st in 2019), and children and sports ranked 28th in 2019.

　　What was eliminated were mobile sports app (ranked 13th in 2019), fascia relaxation equipment (ranked 14th in 2019), team personal training (ranked 19th in 2019) and rehabilitation guidance (ranked 20th in 2019). Generally speaking, the current fitness trend in China is still dominated by basic sports such as "running and jumping". Compared with the global trend, there is no further detailed classification of functional training and fitness plan. It can be seen that China’s fitness industry is still in the initial stage of development. Grasping the current trend and characteristics of China’s fitness development, we should still uphold the main purpose of letting most people move first in fitness promotion, and at the same time let people who participate in sports exercise more scientifically.

　　Finally, this year’s fitness trend in China entered the list for the first time and ranked third. Good doctors are similar to the global fitness trend, and both are in the forefront, which also reflects the rapid development of the integration of sports and medicine in China and the rapid increase of public acceptance. For the treatment of related chronic non-communicable diseases, the public is gradually turning their eyes from traditional single medical treatment to the combination of sports and medicine. Incorporating physical activity assessment and targeted exercise and fitness guidance during medical treatment can not only effectively promote the health port to move forward, reduce medical expenses, but also open up a new path for building a healthy lifestyle.

　　On the evening of April 29th, outside a shopping mall in Shaoxing, Zhejiang Province, players took part in the first the glory of the king Mobile Games Competition in Shaoxing. It is understood that more than 100 teams participated in this competition. Photo courtesy of vision china

　　As a national MOBA (multiplayer online tactical competition — — Reporter’s Note) Mobile Games, the glory of the king has set off a national carnival. According to the data shared by Ma Xiaoyi, vice president of Tencent, the number of users in the glory of the king exceeds 300 million, and there are more than 50 million active users every day.

　　Many stars are not immune to customs. Yang Mi, Angelababy, Michael Chen, Fox Xia and Karry are all die-hard fans of the glory of the king, and from time to time they have to "open the black" and then show off their achievements in the circle of friends. Papi sauce also joined the army of players in a trendy boat, and made a special talk show to spit out the glory of the king’s experience of playing for a month. "You won by yourself, but you lost by your teammates.".

　　As a game, the glory of the king has become a social way of entertainment and relaxation among friends, while as a profession, e-sports players who seem to be "kings" have unknown sadness.

　　From moving bricks to playing professional games, people are becoming more and more confident.

　　God Man (the glory of the king ID) is a post-95 generation who just turned 20 this year. Although I only graduated from junior high school, I am already the main force of the championship professional team of the glory of the king Professional League (KPL), and I have my own fan support group. Just like a star, it is easy to open a live game with tens of thousands of viewers.

　　In March 2017, the KPL Spring Tournament started. AS the former king, As Xiange Club, where Shennan worked, needs to accept new challenges from various teams. Today, the competition has been carried out for more than half. Although AS Xiange temporarily ranked sixth with a record of 7 wins and 9 losses, at the scene of the competition, the shouts of fans "Come on Xiange, Xiange will win" are still one after another. Front-row fans with fluorescent boards held high the publicity photos of the team members, and spelled with fluorescent lights "Come on, God is invincible" … …

　　The game has completely changed the life track of Shennan.

　　Shennan was born in the countryside of Hepu County, Beihai City, Guangxi Province. Apart from the money earned by his elderly father moving bricks on the construction site, the old sow raised at home is the economic source of the whole family. He also has two sisters and a younger brother. As the eldest son, he needs to bear the main responsibility of the family.

　　Shennan went out to work after finishing junior high school. He hoped to earn money to supplement his family and let his younger brother finish reading the book. At that year, the 16-year-old Shen Nan was underage and could not go to work in a regular factory or company. He had to come to a construction site and work as a brick mover. A body weighing less than 100 pounds shuttles through the loess construction site every day, and the wages are sent to the family. God saved money and bought a computer a few months later.

　　Shennan told China Youth Daily and Zhongqing Online reporter that games are his biggest hobby. He has been playing since primary school, from Warcraft to crossing the line of fire, from Dream of the Three Kingdoms to the glory of the king. "I have played almost all the games that cost nothing, which is a typical Internet addiction teenager."

　　In 2015, Shennan came to Shenzhen and settled in a Shaxian snack bar, which is similar to Shaxian snacks all over the country, with a menu hanging on the wall, selling a bowl of American ginseng black-bone chicken soup from 8 yuan and a rice covered with shredded pork with pepper from 12 yuan. His salary is more than 1600 yuan per month, including food and shelter.

　　Every day, the meal is the busiest time in the store, and it is also the time when he talks the most in a day. He mechanically places food orders, serves food and checks out, cooks noodles and fried noodles, and it is the same every day. "Boredom" is the first adjective that Shennan thinks of when he recalls that time. When there is no one in the shop, Shennan will play games to kill time.

　　The glory of the king just opened his clothes in 2015, which was the most boring time for Shennan in Shaxian snack. There were no other peers in the store, so the game became his best companion. "I feel happy only when I play games." Shennan said.

　　In order to get a better ranking in the division, Shennan often stays up until dawn and then goes to work directly. "If you want to be more powerful, you have to make more efforts. The higher the ranking, the more popular and respected it is." Shennan admits that with the promotion to the first place in the division, he feels that he is different and more confident.

　　God man gradually became obsessed with the glory of the king, and then simply quit his job and started to practice. 5 yuan has a star, and the star is an integral system, and each level is clearly marked. Shennan rented a cabin in 400 yuan every month and opened the Internet. During that time, he stayed at home. Except for eating and sleeping, his eyes never left his mobile phone. Sometimes he ordered a takeaway meal within 10 yuan one day. Then keep practicing skills and hand speed until you are selected by the Xiange team.

　　When the game becomes work, the sense of entertainment disappears.

　　After joining the team, God Man’s day began at noon. Start training with your mobile phone at noon every day until one o’clock in the morning, and then play until two or three o’clock in the middle of the night to keep a good feel. Make up sleep in the morning and cycle again the next day.

　　However, his salary has changed from 1,600 yuan in Shaxian snack to 6,000 yuan now. Live games and competitions will give him more income. "Finally, I don’t have to worry about money. Except for the necessary expenses, I will send it to my family. The family needs money more." Shennan is satisfied with his present income.

　　"On average, I have to play for more than 12 hours a day. It is completely mental work, and I often have headaches, eye pains and finger pains. There is no rest day and no private time for game training. The whole team lives in the base, which is actually much harder than going to work, especially tired. " Shennan admits that when the game becomes a job, the sense of entertainment disappears.

　　Uninterrupted training made Shennan’s girlfriend in Shenzhen choose to break up. God male wry smile way, playing e-sports is can’t find a girlfriend.

　　The glory of the king ID, the teammate of Shennan, has a girlfriend who has been in contact for a long time, and has not seen each other for a long time. He only gets up at 10 o’clock to do the live game task before connecting with his girlfriend for interactive love.

　　Wu Xun was born in 1995, and joined the club when it was just established. At that time, he was still a freshman. Because of his good performance in online competition, he persuaded his parents to drop out of school and became a professional player with the dream of winning the game.

　　The difficulties in the early days of the club’s establishment are still fresh in Nontrace’s memory, because the funds are tight and the players have to make up some expenses themselves. When they went to Shanghai to play a game, they rented a house in a remote suburb. A dozen people were divided into bunk beds and squeezed into a room, "just like a humble abode", and they were also rented by the police as a group. It takes more than two hours to get to the stadium from the residence. In order to save money, several people pooled a subway ticket to get in. Due to the lack of income, a group of people gather together to eat instant noodles. On average, the daily meal fee per person is less than that in 10 yuan.

　　"It depends on dreams to persist." Non-trace said that it was really hard during the game. At night, I discussed and studied tactics until three or four in the morning. I went to play the game during the day the next day and then held a summary meeting when I came back at night. There was no rest time at all, and when he couldn’t bear it, he took a half-day off and fell asleep.

　　Traceless told reporters that there is no human feelings in the game circle, and it is completely the survival of the fittest, relying on strength to speak. With the update of the version, you need to constantly "update". If you can’t keep up with others, you may be kicked out. Non-trace was almost optimized out. In order not to be thrown out, he practiced hard for several days in private and hardly had any rest.

　　I feel lucky to be able to turn what I like into a career. Although being a professional player is black and white, it is very hard and stressful, but it can get a good income. Because I joined the club earlier and have strong ability, I can earn tens of thousands of yuan every month. Wuji just wants to make himself stronger and win more championships in the game, but he hasn’t considered his future life.

　　The same is true of Shennan, who is still confused about his future life and just wants to win the championship next season. Last year, the champion team of KPL won a bonus of 800,000 yuan. If they win the championship again this season, they will also get a share of the bonus. "I hope to make more money, let my brothers and sisters live better, and let my parents who have worked hard all their lives have a happy old age." God man is glad that he can be found in the crowd, otherwise he might still be a waiter in a small shop.

　　But they all know the cruelty of game competition, and everyone is working hard for the dream of champion, because it is also directly proportional to their reputation and income. They clearly remember what the coach once said: "If there is no result, even breathing is wrong." The champion’s scenery will not last forever.

　　On August 18th, the Central Radio and Television General Station held the conference of "2023 Taihu Beauty Concert" in Beijing. Wang Xiaozhen, deputy director of the Central Radio and Television General Station, and Zhang Aijun, member of the Standing Committee of jiangsu provincial party committee and Minister of Propaganda Department, attended the conference and started the program together with the guests.

　　The "2023 Taihu Beauty Concert" carefully created by the Central Radio and Television General Station will be recorded in Wuxi, Jiangsu Province, which is known as the "Pearl of Taihu Lake and the Shengdi of Jiangnan". With the theme of "Taihu Lake Beauty", the program invites state-level literary and art troupes and literary and art workers who are deeply loved by the public to come to Wuxi to paint a new picture of Taihu Lake with elegant charm in the south of the Yangtze River through various artistic means such as "live performance+virtual presentation".

　　Zhang Guofei, head of the Cultural Program Center of the Central Radio and Television General Station, introduced the innovative highlights of the program. The program takes Wuxi as the origin and radiates around Taihu Economic Circle. Through the form of "main venue+sub-venue+multi-scene shooting", it attracts audiences of all ages to go to a literary and artistic event that is both ideological, artistic and ornamental, and presents a brand-new image of Wuxi as a city of intelligent manufacturing, a city of happiness and a beautiful place.

　　Zhang Guofei, head of the Cultural Program Center of the Central Radio and Television General Station

　　Ji Ming, the stationmaster of Jiangsu Station of Central Radio and Television Station, said that the area around Taihu Lake has beautiful scenery, rich products, rich people and rich people. It has been a well-known land of plenty since ancient times, and now it has become a hot spot for reform and opening up and a pioneering area for modernization. The program plans a special concert with the theme of "Taihu Lake Beauty", which is to fully show the beauty of humanity, ecology, technology and development of Taihu Lake through the integration and innovation of "thought+art+technology" at the main station.

　　Xinhua News Agency, Beijing, June 21st　

　　Xinhua News Agency "Xinhua Viewpoint" reporters Li Shuangxi, Li Wei and Xie Ying

　　Recently, it is the peak period for college students to submit course papers, defend and review their graduation thesis. A survey by Xinhua Viewpoint reporter found that some college students are quietly using AI (artificial intelligence) writing software such as ChatGPT to write papers, or using AI to assist paper writing, such as listing outlines, polishing language and reducing repetition rate.

　　Will AI writing software encourage academic fraud? Should I care?

　　AI software to write papers

　　Cheng Guangyu (pseudonym), a junior in a university in Beijing, will hand in four course papers this semester, each of which is required to be about 3,000 words. Cheng Guangyu didn’t spend time reading literature, sorting out, extracting and writing. He stayed up all night before handing in his homework and finished his paper with ChatGPT.

　　"At first, I was worried about whether I could finish it. As a result, I gave ChatGPT a general direction, and it listed the outline of the paper and automatically continued to write, which was much better than me." Cheng Guangyu finished four papers in one night, and submitted them to the teacher after simple revision.

　　According to the investigation in some colleges and universities, some college students use ChatGPT to complete course assignments, final papers and even undergraduate or master’s thesis. "The threshold for undergraduate graduation thesis is low, and I have no scientific research ability. Many people’s undergraduate papers are extracted and pieced together online, and it is more convenient to hand them over to artificial intelligence now. " Qiao Yifan (a pseudonym), a senior student at a university in Wuhan, said.

　　AI writing software can be used in all aspects of paper writing, from outlining and writing some contents to polishing language and reducing repetition rate. However, a college student who has used AI writing software in a university in Hunan Province thinks that the effect of modifying and polishing articles with AI software is not bad, but it is not appropriate to use it for substantive research and elaboration of innovative ideas.

　　The reporter found that AI writing software similar to ChatGPT is not uncommon in China. For example, Zhichuang helps AI, the secret tower writes cats, draws pictures and writes quickly, etc., and generally supports the writing of articles and papers. In addition, there are many articles teaching how to write papers with AI software on websites such as Zhihu and Xiaohongshu. In the experience sharing, some netizens said: "The teacher can’t see it at all", "Praise the AI ? ? paper for being well written" and "gave me excellent papers".

　　During the interview, some college teachers also found the characteristics of AI papers. When examining an undergraduate’s thesis, a teacher majoring in international politics in a university in Jilin Province found that his thesis on Japanese culture was biased, with blunt and lengthy language and empty content. Under the teacher’s questioning, the students admitted that the paper was written in ChatGPT.

　　In addition, some papers written with AI software are full of mistakes. "If you check it carefully, you will find that the links of the cited papers can’t be opened, the author’s name can’t be searched, the publication time, journals, pages, SCI divisions and other contents of the papers are all false, and even some historical events involved are out of thin air." He Shiming, an associate professor at the School of Computer and Communication Engineering of Changsha University of Science and Technology, said.

　　"Help scientific research" or "encourage cheating"?

　　Can ChatGPT be used to assist thesis writing? Many college teachers are controversial about this, including those who support users, those who resolutely oppose it and those who demand that it is strictly prohibited.

　　It is understood that some foreign universities have explicitly issued regulations prohibiting the use of ChatGPT to write papers. In China, academic journals such as Journal of Jinan (Philosophy and Social Sciences Edition) and Journal of Tianjin Normal University (Basic Education Edition) have successively issued explanations on the use of artificial intelligence writing tools, indicating that if the author uses relevant tools in his paper creation, he should explain the degree of use in detail in his article.

　　For research purposes, Yang Zhiping, a professor of Marxism at Northeast Normal University, tried to use AI writing software. He found that in order for AI to provide correct ideas, it is necessary to constantly "feed" the corpus to AI. In the questions and answers with AI, the original vague research ideas gradually became clear. "It’s like exchanging ideas with an expert with encyclopedic knowledge. Through the collision of ideas, new academic viewpoints can be inspired." Yang Zhiping said.

　　"AI writing software is just like search tools such as Google and Baidu. When it first appeared, it always caused people’s panic." Yao Yuchun, dean of the Institute of Social Sciences of Jilin University, said, but fundamentally, AI writing software is still a tool. It is a product of science and technology and needs to be treated dialectically. If students only use it for limited purposes, such as searching documents, listing outlines, sorting out ideas, etc., it is understandable and cannot be banned.

　　Fu Weidong, a professor at the Department of Artificial Intelligence Education of Huazhong Normal University, believes that both manual writing and AI writing should be regarded as academic misconduct as long as they exceed the prescribed repetition rate according to the existing academic paper norms. In addition, AI writing is based on the retrieval and processing of existing knowledge. Repetition of sentences or plagiarism of ideas is inevitable, which will inevitably involve disputes over intellectual property rights and portrait rights, and should be strictly regulated.

　　A college teacher in Hunan province is worried that if students are allowed to use AI to write, it will not be conducive to cultivating students’ scientific research ability. In the long run, it is easy for students to develop inertia and form a bad academic atmosphere.

　　In addition, the information security problems that may be caused by AI software have also attracted attention. Li Huilai, a professor at the School of Artificial Intelligence of Jilin University, said that some countries in Europe wanted to "block" ChatGPT because of data security problems, because there was a hidden danger of "collecting, using and disclosing personal information without consent" when it grabbed data. Li Huilai pointed out that when domestic students use ChatGPT, it may lead to the abuse of domestic scientific research results, and there are data security risks.

　　Actively respond to the academic challenges brought by AI technology

　　Some industry experts believe that, like search tools, as a technology, the popularization and application of AI is irresistible. The application standards of AI writing tools should be formulated as soon as possible to standardize the scope of use; At the same time, change the traditional evaluation mechanism of students in colleges and universities, and provide AI writing detection tools for researchers. In addition, it is necessary to strengthen independent research and development in the field of artificial intelligence and master core technologies.

　　Xiong Bingqi, president of 21st Century Education Research Institute, believes that it is difficult to ban AI writing software, and we should try to "keep the devil in a bottle" and make clear the scope and degree of use of AI writing tools. "It is better to face up to it than to avoid it. Colleges and universities can even offer public courses using AI writing tools, and clearly teach students the norms, methods and academic ethics. "

　　He Shiming believes that the duplicate checking software used in colleges and universities has been difficult to cope with AI writing. At present, universities and academic journals lack special software to detect AI writing, and it is inevitable to "hang a leak" only by human eye recognition. It is hoped that relevant domestic institutions will develop software to identify AI writing, and provide a safer and more reliable anti-academic fraud system for colleges and universities.

　　In order to avoid the influence of AI writing, some foreign universities are reducing the open homework after class, and putting more emphasis on classroom homework, handwritten papers, group work and oral test.

　　Xie Di, an associate professor at the School of Public Administration of Hubei University, suggested that the education department should pay more attention to students’ problem consciousness, observe, understand and analyze the society’s nature, and increase the proportion of content with substance such as experiments and investigations, rather than overemphasizing the form.

　　ChatGPT has powerful functions and may bring a new scientific and technological revolution. Li Huilai believes that domestic research and development of artificial intelligence should be strengthened. At present, some domestic companies are also developing similar products, but they are still in the initial stage and cannot form strong competition with ChatGPT.

　　"It is necessary to use the window period to accelerate the development of Chinese AI applications and AI paper detection systems, and strengthen the independent research and development of artificial intelligence core technologies." Fu Weidong said.

　　Zhejiang Online November 2 (Zhejiang Online reporter Huang Yunling)Face recognition in mobile phones, smart speakers in rooms, driver assistance systems in cars, "AI quality inspectors" in factories, and traffic lights with "eyes" and "brains" on urban roads … … Artificial intelligence, once mysterious, is now being used more and more.

　　The new prosperity of artificial intelligence has provided support for the convenience of life and the digitalization of the empowerment industry, which is outstanding in Zhejiang. Related enterprises represented by Alibaba, ArcSoft and Rokid have made great achievements in the fields of voice interaction and visual recognition. Hangzhou Artificial Intelligence Town, Zhijiang Laboratory and Artificial Intelligence Industrial Park have been established one after another, providing a platform and technical backing for industrial development. It is reported that in the next three years, Zhejiang will concentrate its efforts, gather resources, integrate policies and intensive services, and strive to achieve the scale of Zhejiang’s artificial intelligence industry exceeding 50 billion yuan, so that the artificial intelligence industry will lead Zhejiang’s future development.

　　Artificial intelligence application Pratt & Whitney family life

　　If you want to say a symbol product of artificial intelligence technology landing, smart speakers may be the answer of many people. With the maturity of speech recognition technology, it is expected to become a new medium of human-computer interaction, and the music and home attributes make it more acceptable to users.

　　"Smart speakers are a point we cut into in the artificial intelligence industry." Vice President Rokid told Wen Jie.

　　In 2014, Rokid Company was established in Hangzhou; In 2016, Rokid’s first product, Ruoqi Alien, was released; In 2017, Ruoqi Lunatone appeared. Rokid’s previously published data shows that Rokid’s artificial intelligence products have interacted with users for 100 million times, from aliens to Lunatone. At this year’s Light of the Internet Expo, Lunatone will also appear in Wuzhen together with two other Rokid products.

Rokid smart home sandbox that simulates real family scenes, a smart speaker can control lighting, home appliances and curtains.

　　Now walk into the house and shout "Ruoqi, turn on the light", and artificial intelligence can accurately execute your instructions. "More and more sensitive awakening, more and more accurate voiceprint recognition, and better experience feedback are the goals of Rokid’s efforts." Xiang Wenjie said.

　　In addition to voice, visual artificial intelligence is also subtly changing people’s lives.

　　The closest and most popular terminal landing product of visual artificial intelligence is smart phone. At present, intuitive artificial intelligence technologies such as mobile phone face recognition and unlocking need not be repeated, and the beauty technology that changes users’ photo habits is also attributed to visual artificial intelligence.

　　"The trick to make beauty feel no contradiction lies in the mature face technology, and its accuracy directly determines the effect of beauty application." Zhu Lirong, vice president of ArcSoft ArcSoft, told reporters. The background blur function, which is often used in mobile phone photography, also uses the recognition technology to accurately distinguish the subject and background of the photo and divide it perfectly, so as to achieve this shooting effect that was originally only available on SLR.

　　Founded in 1994, ArcSoft moved its corporate headquarters in Silicon Valley to Hangzhou in 2017. According to reports, whether it is foreign brands such as Samsung and LG, or domestic manufacturers such as Xiaomi, Huawei, OPPO and VIVO, many of the visual artificial intelligence technologies they use come from ArcSoft.

　　Zhu Lirong told reporters that with the popularization and downward penetration of artificial intelligence knowledge, users’ awareness is better and the scenarios of intelligent applications are becoming more and more abundant. At present, ArcSoft is still using visual artificial intelligence technology to empower unmanned retail containers, intelligent driving and other practical fields. At the same time, ArcSoft’s open platform for visual artificial intelligence is using a variety of free technologies to promote the full implementation of artificial intelligence.

　　Artificial intelligence technology empowers industrial development

　　In the polycrystalline battery production workshop of Zhengtai Solar Factory in Binjiang District, Hangzhou, a quality inspection machine grafted with artificial intelligence "brain" is working: after the battery is imaged, the machine can automatically identify whether there are defects and make detailed classification according to different causes of defects.

　　This is an AI quality inspection project jointly established by Zhengtai New Energy and Alibaba Cloud. Wei Xihan, an algorithm expert in charge of industrial vision diagnosis in Alibaba, told reporters that Alibaba Cloud ET industrial brain has intensively studied more than 40,000 samples through deep learning and image recognition algorithms, thus realizing the real-time and automatic judgment of battery defects by the machine, liberating labor and doubling the detection speed.

　　More importantly, with the improvement of automation level brought by the empowerment of artificial intelligence, factories can also use big data for systematic analysis, such as where there are more defects in the battery, what kind of defects account for the proportion, and which process it may be related to, which in turn will promote the improvement of long-term production and improve the yield.

　　"At present, the yield of battery chips is around 95%. Every percentage point increase can bring tens of millions of cost savings to the company every year." Huang Haiyan, vice president of Zhengtai New Energy, said.

　　The upgrading and transformation of the industry by artificial intelligence technology is also reflected in the transformation of the automobile industry.

　　As an intelligent application embodied by vision, voice and other technologies, autonomous driving is an unavoidable topic for artificial intelligence.

　　Shallow snow, general manager of Alibaba Artificial Intelligence Laboratory, told reporters that the laboratory has developed a complete set of automatic driving system, which has been repeatedly tested and verified, and the bicycle intelligence has reached L4 level.

　　On this basis, based on the limitations of bicycle intelligence in terms of cost and safety, the laboratory also innovatively developed a vehicle-road collaborative intelligence system. According to Shallow Snow, this system realizes the integration of cloud, road and car through self-driving car+roadside "sensing base station"+cloud control platform.

　　It is reported that Alibaba’s artificial intelligence laboratory has done a lot of practical tests. At a speed of 30 km/h, when encountering sudden pedestrians, with the cooperation of intelligent sensing base stations, it can achieve a 100% successful avoidance rate.

　　"Artificial intelligence should not be tall, but bring more fairness and inclusiveness." Shallow snow said. In September this year, the Hangzhou Municipal Government took the first photo of Hangzhou’s autonomous driving to Alibaba, and Ali will also join hands with industrial partners to make the vehicle-road collaborative technology truly land, making China’s autonomous driving different.

　　Zhejiang: Making Artificial Intelligence Industry Lead the Future Development

　　"A very small kernel has brought about great changes. The Internet is like this. We believe that artificial intelligence is also the same." Xiang Wenjie told reporters.

　　At present, a new generation of artificial intelligence is profoundly changing the economic and social development model. Accelerating the development of a new generation of artificial intelligence is a priority strategic choice to conform to the new round of global scientific and technological revolution and industrial transformation trend, win the initiative in development, and also a priority layout direction to promote the upgrading of economic and social intelligence.

　　Zhejiang is relying on the first-Mover advantage of information economy, artificial intelligence research and development and industrial application to speed up the pace of layout.

　　In December 2017, Zhejiang Province issued a new generation of artificial intelligence development plan, which made a strategic layout for Zhejiang’s information economy, artificial intelligence research and development and industrial application.

　　According to the plan, by 2022, Zhejiang will make important progress in the frontier theory, core technology, supporting platform, innovative application and industrial development of artificial intelligence, and the overall technology and industrial development level of artificial intelligence will lead the country and keep pace with the international advanced level.

　　China (Hangzhou) artificial intelligence town, located in the future science and technology city in the west of Hangzhou, is an important step in the layout of artificial intelligence in Zhejiang. In July last year, the artificial intelligence town opened. In one year, 17 artificial intelligence industry project platforms including Zhijiang Laboratory and Baidu (Hangzhou) Innovation Center have settled in the pilot area of the town.

　　At the same time, through the evaluation of artificial intelligence town projects, more than 290 recommended projects are entering the town in batches. As of mid-September this year, more than 120 enterprises, including Seruban, Lingxi Intelligent and Cognitive Technology, have settled in their offices.

　　Jin Guo, deputy director of the Innovation and Development Service Center of the Future Science and Technology City, told reporters that the artificial intelligence town will give full play to the talents, capital, industrial advantages and experience in the construction of characteristic towns, and strive to build a national artificial intelligence industry cluster leading area and an artificial intelligence innovation highland with global influence.

　　What will the future of artificial intelligence be like? The whole world is waiting to see. However, as Xiang Wenjie and Zhu Lirong, who have been in the business for many years, said, the actual change value brought by artificial intelligence is great, and whether it is successful or not, it has its significance. "We don’t know what the future is, we just try and innovate."

　　With their contribution, artificial intelligence, Zhejiang is catching up.

exactly

Hands covered with mud, shoulders soaked with sweat,

Clear and firm eyes, kind and brave heart.

They have no steel body, but they are extremely powerful.

They have no grandiloquence, but they work hard.

There is no infrastructure fanatic here, only Chinese power!

At present, China Construction has installed Wuhan, which is participating in the construction.

Vulcan Mountain and Thunder God Mountain hospital have been put into use,

In the face of the epidemic, China construction and installation forces assembled in the line of fire.

Rushing to the front and fighting on the "epidemic" line,

Their Wuhan war "epidemic" will come to an end temporarily.

Behind this life-and-death race with the epidemic,

It is the builders who have paid hard work and strength.

They don’t pay, they don’t give up day and night, they are ordered in danger,

Go to the hardest, most tiring and most dangerous front,

Casting a new fortress for epidemic prevention,

They are ordinary heroes of this era!

Today, let’s walk into the story behind "China Speed"

……

Liu Xu: I’m not tired. I’ll just sleep for a while.

___

On the morning of February 11th, a circle of friends of Wang Junsheng won numerous praises. Liu Xu, a labor worker who fought all night for 28 hours, fell asleep at the scene. "They are not online celebrity, but they are the people who can bear hardships the most. There is nothing that can’t be done with ventilation and water and electricity at the scene. They are the most lovely people. I am proud of these workers and brothers." Wang Jun is full of regrets. When Liu Xu was mentioned, all the managers at the scene gave him a thumbs up, but he always said, "Nothing, it’s okay to do your best." Liu Xu, a 32-year-old native of Huangmei County, Hubei Province, was the first to arrive at the construction site of Raytheon Mountain together with the China Construction and Installation Unit. After staying up all night, he turned to the Huoshenshan Mountain for support the next day, and returned to Raytheon Mountain to help with the finishing work after the delivery of the Huoshenshan Mountain.

He is Luo Wenhao’s right-hand man with many years of construction experience in the Vulcan Mountain project. "I have participated in many projects, and it is the first time that it is so urgent." Due to the urgent construction period and shortage of labor resources, the assembled labor team may not be professional counterparts. In order to ensure the construction quality, he should fully disclose with every worker before the construction, and there should be no omissions in every link from explaining drawings and personnel scheduling to the handover of the working face. The on-site construction area is large, and a large amount of materials must be lifted by the workers themselves. "It takes four or five hundred meters to carry it back and forth once, and tens of thousands of steps a day are commonplace." Liu Xu said airily.

During the construction of Vulcan Mountain, he was caught in several heavy rains, and the scene of everyone working in the rain made him remember deeply. "The rainy road is not easy to walk. You have to wring your pants and shoes to continue your homework. Wet feet on rainy days, sweaty feet on sunny days, and feet are often soaked. " Mentioning the hard work, he smiled and said, "I wouldn’t come here if I was afraid of being tired!" We brothers can come to the scene because we hope that the hospital can be built as soon as possible, and it is worthwhile to work hard! "

Defeng Chen: Children who grew up in the countryside are all right.

___

Squatting on the material box in the corner, I simply took a few mouthfuls of lunch, and Defeng Chen climbed up the roof to inspect the finishing work of the HVAC system. This is the eighth day that he fought with everyone in Wuhan "Two Mountains" Hospital. He ate, lived and worked with everyone every day, but Defeng Chen, deputy secretary of the Party Committee, secretary of the Discipline Inspection Commission and chairman of the trade union of China Construction and Installation Group, was very practical in his heart.

In those days, it was rainy and rainy in Wuhan, the construction site was full of water, muddy and slippery, and the cold wind and rain hit the face, but the scene was in full swing. Colleagues advised Defeng Chen to take a rest first. "Don’t worry about me, everyone is working against time. I want to keep an eye on the progress, coordinate personnel and pay attention to everyone’s safety!" His firm eyes can’t hide his tiredness.

With the delivery of the two hospitals, the construction personnel at the installation site of Zhongjian are preparing for the final maintenance and withdrawal work. In addition to supervising the progress, safety and quality of the project on the spot every day and assisting in coordinating various resources, Defeng Chen also cares about understanding the psychological dynamics of the workers from time to time, constantly encouraging the team and boosting confidence.

Late at night, Defeng Chen was still on the construction site and conducting various inspections at the headquarters. He didn’t return to his residence from the construction site until after 1 am, every day. "Children who grew up in the countryside, this is no problem!" A simple word hides great energy.

In order to give full play to party member’s vanguard model and the role of the party organization as a fighting fortress, China Construction and Installation quickly set up a temporary party branch, and Defeng Chen awarded the flag to the commandos on the spot. "Stand up at a critical moment, turn back when the masses need it, perform their duties, and it is the duty and duty of party member cadres to charge ahead!" Defeng Chen encouraged everyone.

When China Construction Installation successfully completed the assignment task and the workers were preparing to leave the site for isolation, Defeng Chen noticed that other Chinese construction brothers were still fighting in other working faces. Defeng Chen immediately arranged manpower to help his brother units complete various projects. "At the critical moment, we must not slack off, and we will definitely complete the tasks entrusted to us by the party and the people from the beginning to the end!" After the delivery of the hospital, Defeng Chen is still concerned about the payment of workers’ wages, the withdrawal of the field and the follow-up guarantee of the project.

Yu Junchao: a warm-hearted "contractor"

___

Yu Junchao, a 50-year-old party member, is the head of the 168 Construction Engineering Company of China Construction Installation Cooperative Labor Service Company. On the afternoon of January 27th, after receiving the call for aid construction, Yu Junchao and all 11 team members of the company immediately arrived at the scene. "Many workers volunteered to take part in the war, and soon an 83-person labor force was assembled at the scene of Raytheon Mountain." Yu Junchao was very moved, and everyone gave up the opportunity of reunion to go to Han to support the construction, which strengthened his confidence in doing a good job in the project.

Yu Junchao and his team are warm-hearted. When they first entered the site and were not assigned construction tasks, they took the initiative to help other builders carry logistics materials. On the first day of entering the site, they completed the construction tasks of laying drainage pipes and "two cloths and one membrane" for 12 hours. During the construction period, Yu Junchao led the team to fight all night, and only rested for 2 hours every day during the busiest time. He completed the ventilation and drainage tasks on the 15th and 16th floors of Raytheon Mountain Area 2 and the 6th floor of Area A with high standards, which won everyone’s praise.

Gu Jianbing: the "Commander" of the whole battle

___

Command team, material allocation, logistics support … Gu Jianbing, Party branch secretary of China Construction and Installation Beijing Company, is both a commander and a combatant, and always carries out management to the end of details. On-site inspection was conducted at one or two in the morning, and the construction quality was comprehensively checked. After returning to his residence, he was assigned to work the next day. Gu Jianbing could not fall asleep until four in the morning. Three hours later, he appeared on the construction site on time to guide the labor team to make handover and make thoughtful arrangements for installation tools, technology and working face. During the day, the working face is fully spread out, the coordination workload is huge, and the intensity of work day and night makes Gu Jianbing’s voice hoarse all the time.

The sudden construction task has also brought many problems. Hospital construction needs manpower, and the supply of building materials is even more urgent. He asked for help and mobilized everywhere, and several cooperative labor service companies immediately gave support. Suppliers in Wuhan building materials market also took the initiative to supply building materials at the lowest price. Gu Jianbing also received rubber and plastic insulation materials donated by suppliers. The branches of China Construction and Installation also responded positively. In just two days, nine brother units quickly supported nearly 30 managers and more than 300 laborers. In this way, in one day, all the building auxiliary materials arrived and all the personnel were in place, which solved the urgent need.

During the critical period of work-grabbing, all the staff fought almost all night. Gu Jianbing had to arrange the production schedule, safety and quality, and at the same time, he had to keep in touch with the labor service team at all times, so as to relieve the fatigue of the staff and arouse the enthusiasm of the workers. During the construction, due to the narrow construction space in the ward, Gu Jianbing led the team to take local materials, opened up a small processing area on site, and prefabricated the water pipes in advance, which effectively improved the construction efficiency.

The "Huolei" hospital has been put into use one after another. At this moment, Gu Jianbing continues to run around in organizing personnel to withdraw from the field, isolate and debug and maintain the hospital in the later stage. "It’s nothing if we can successfully complete the tasks assigned by the state and the people and get the patients treated as soon as possible!" Gu Jianbing said.

Wang Hui: There are always more ways than difficulties.

___

Wang Hui, head of electrical technology of Wuhan Thunder God Mountain hospital Medical Technology Building. The site construction environment is complex and crowded. The first thing Wang Hui did after entering the site was to quickly organize workers to carry out safety and epidemic prevention and control education, and distribute epidemic prevention supplies to improve workers’ safety awareness.

The construction period is tight and the task is heavy. If we follow the established drawings and the conventional installation process, we may not be able to catch up with the construction period. Wang Hui analyzed the actual situation on site and improved the design on the premise of ensuring the function and quality, such as installing formal lighting equipment in advance to avoid the delay of the construction period caused by disassembling temporary lighting equipment after the project is completed; After optimization, the original ceiling lamps were changed to wall-mounted installation; The lighting trunking originally needed to be equipped with a separate bracket. Wang Hui skillfully grafted the existing lighting bracket to the built pipeline bracket, which not only facilitated the subsequent threading, but also improved the construction efficiency.

Through Wang Hui’s "small creation", the installation method has been optimized, and the construction period and cost have been greatly saved. "The method is always more difficult than it is!" Wang Hui always encourages everyone like this.

Wang Junsheng: A "Big Butler" who takes care of everything.

___

Wang Junsheng is the front-line commander of Wuhan "Two Mountains" Hospital. This "big housekeeper" has been fighting with his brothers for more than ten days at the scene. From the construction arrangement, labor dispatch, personnel management and logistics support, he must personally ask questions.

Before the start of construction, Wang Junsheng reversed the construction period, made a good road map, unified planning, organization and coordination, and made a good job of interweaving processes and processes to ensure that everyone was coordinated and gave full play to their professional strength. He also called construction workers in advance to explain the detailed installation sequence of each process to the labor teams. Under the overall planning and management of Wang Junsheng, which is accurate to the hour or even minutes, more than a dozen labor teams and more than 300 construction workers closely cooperated to build with high quality, and there has never been any rework on the site.

In addition to construction, Wang Junsheng is equally worried about everyone’s "eating, drinking, living and transportation". He coordinated everywhere and arranged comfortable hotels for the construction workers; In order to avoid the gathering of canteen staff and let everyone "eat with confidence", he took the initiative to contact the delivery of working meals and pay the wages of workers to solve everyone’s worries.

Cai Juntao: Create opportunities without opportunities.

___

Cai Juntao is the leader of a company’s expedition to Wuhan, and also the electromechanical director of Thunder God Mountain hospital Medical Technology Building. Create the working face, arrange the working procedure reasonably, find the construction equipment, and arrange the team to enter the site … … Hundreds of phone calls a day have become commonplace for Cai Juntao, which has turned him into a magnetic "subwoofer".

When he first arrived at the scene, difficulties came to him. What bothered him most was that the internal structure of the medical technology building was complex, and the construction unit had many cross-operations. What should I do if I wanted to catch up with the progress but didn’t have a working face? After inspecting the site, Cai Juntao decided to adopt the assembly construction method of off-site prefabrication and on-site installation, hand over one working face and install one immediately, and never delay the construction period!

Finally, after several days of hard work, the medical technology building was delivered as scheduled. Cai Juntao sleeps only 2 hours a day on average. He often misses his meal time because he is dealing with on-site work, so he can only fill his hunger with instant noodles. He and his colleagues call each other ‘ Iron man ’ Brother. "Time is life! Eliminate all difficulties, pay close attention to construction, and create opportunities without opportunities! " This is what Cai Juntao said the most.

Tamia Liu: No matter how tight the time is, the quality will never be discounted.

___

Tamia Liu, a HVAC engineer in China Construction Installation International Engineering Branch, as an "overseas", spent the first Spring Festival with his family in China in four years, but it took him less than 90 minutes from receiving the notice of supporting the construction of Raytheon Mountain to arriving at the site.

The amount of on-site work is large and the construction period is tight, but the negative pressure requirement of the infectious disease isolation ward is high. "No matter how tight the time is, the quality must not be discounted!" Tamia Liu is responsible for the installation and debugging of three negative pressure isolation wards. For the installation of large-scale equipment and room branch pipes on the roof, Tamia Liu decided to adopt modular assembly, which can be installed in place at one time, while ensuring the tightness of the joints of air ducts and accessories. He led the team to work closely with the strong and weak electricity departments, and achieved the one-time test of single machine and system linkage.

After nearly 40 hours of continuous operation, all three negative pressure isolation wards in charge of by Tamia Liu were successfully debugged at one time and handed over to the hospital department smoothly. These wards were promoted as construction models in the whole project.

Li Guanjun: Bite down pieces of "hard bones"

___

Li Guanjun, who was supposed to look after her 2-month-old baby at home during the Spring Festival, signed up as a security administrator in Thunder God Mountain hospital. At the site, he should not only be responsible for safety supervision, but also coordinate the cross-operation of various teams to ensure the safety of personnel and construction in the jurisdiction.

The construction site of Raytheon Mountain is more complicated than previous chemical projects. It covers not only more than a dozen professional systems such as pipeline pre-burying, water supply and drainage, fire fighting, power supply and distribution, ventilation and air conditioning, but also the construction of buildings 15 and 16, which is under the responsibility of "Artisan Brothers Company" of Li Guanjun’s China Construction and Installation Engineering Company, which has a tight construction period and needs to work all night.

The ventilation and installation of 12 rooms in Building A16 must be completed within 10 hours, which is another hard bone. When receiving this task, Li Guanjun has been working continuously for 14 hours, but the ventilation installation not only requires extremely high tightness, but also the installation quality is directly related to the air quality of the ward, so there should be no carelessness. He quickly assembled the team and divided it into five groups by assembly line. He entered the field at 7 pm and worked until 5 am the next day. After a night of fierce fighting, he finally completed the task.

Luo Wenhao: the "New Daddy" in Two-Front War

___

As the front-line deputy commander of the "Two Mountains" hospital project, Luo Wenhao, after receiving the task, simply told his wife who was about to give birth, and arrived at the construction site of Raytheon Mountain in the early morning of January 28th. The first night when he arrived at the construction site, he worked all night. Luo Wenhao led the workers to stay up all night for 12 hours to complete the task of laying "two cloths and one membrane" and laying drainage pipes. The temperature dropped sharply in winter night, and it rained again. Wherever he went, it was muddy and bumpy. Luo Wenhao’s feet seemed to be stepping in the ice hole and he was cold all over. The workers were also very tired, working for 25 hours, all covered with dust.

On January 29th, the project received the task of emergency support for the construction of Vulcan Mountain. He volunteered to lead the workers to quickly turn to the battlefield of Vulcan Mountain for full support, and successfully completed the ventilation and installation project of Buildings 1, 3 and 4. When he was most nervous, he led nearly 200 workers to fight day and night alone. From February 3 to 6, he neglected to contact his family and completed the installation of nearly 4,000 square meters of ventilation pipes in Building 4 for four days and three nights.

On the morning of February 7th, his wife gave birth to her daughter by caesarean section. Exhausted Tam Hao cried with joy on the phone. He named her "Yuan Han" to commemorate this experience of aiding Han. After the Vulcan Mountain project was put into use, Tam Hao, who could have rested, led the workers to Raytheon Mountain to coordinate and command the project closing, debugging and maintenance.

Every minute counts, and the mission will be achieved.

It is these kind, brave, ordinary and selfless people,

Injected into the battlefield in the cold winter

Warm and powerful power.

Thank them,

Let this once lush land come back to life.
