　　Facing the wave of changes brought by Generative Artificial Intelligence (AIGC), the film and television industry is considered to be the first to be affected. How do film and television practitioners view the future of the industry under the influence of AIGC?

Technological innovation brings production popularization.

　　Global magazine: When Sora and other text-generated video models are open to ordinary people, is it possible for everyone to start writing scripts and complete their own movies?

　　Huang Xufeng:Since Sora came out, movies have only been a matter of length. The birth of any new technology may bring about some great changes. After the emergence of smart phones, everyone can shoot videos. And the fact that everyone can make movies may come true in three to five years, maybe even faster, I’m not sure. Because as long as you have this will, you may take the initiative to use the text generation video tool to create a movie you want.

Huang Xufeng at Pingyao International Film Exhibition

　　Zhang eats fish:Film is one of the most complex artistic expressions of human beings, and it is an industrial product of teamwork, so it is not easy to make a big film. For example, the sound part of a movie alone needs complicated processing flow, which can not be solved by AIGC technology at present. So I think that in the future, with the help of artificial intelligence such as Sora, people can shoot online movies for one or two hours, or short plays with good quality, but it is unlikely to complete the production of cinema movies.

Zhang Chiyu is at the shooting scene.

　　I think it will be a very interesting scene if AI can generate its own movies and compete with movies made by humans. By then, films made entirely by human beings will become scarcer and more exciting.

　　In fact, as far as the current situation is concerned, the gap between AIGC and human works is still very obvious. For example, in the current film shooting process, mechanical rocker arm and manual moving lens are used to shoot at the same speed and manner from the same angle, and the texture obtained by manual and machine is different. In different movie scenes, sometimes a sense of machine is needed, and sometimes an artificial texture is needed. They are not mutually substitutive. Like shooting realistic movies, if AIGC technology is used extensively, it will destroy the sense of reality; If it is a science fiction movie, it needs a lot of special effects generated by AIGC.

　　When I was filming Moon Man, it took me half a year to build the Moon Shield Base. Although the current AI may be able to automatically generate a base, their texture is very different, and the feeling of shooting is also very different. For the time being, AI cannot replace the traditional production method.

　　Global magazine: Traditionally, the film and television industry is dominated by a few large film companies. With the popularity of AI technology, are more individuals and small teams more likely to produce high-quality film and television works?

　　Yao Jinli:It’s possible, just like the works of Guo Man produced by many small teams emerged in previous years. Many excellent animated films, such as The Adventures of Li Xianji, were completed by small teams or even single people. For the creator, artificial intelligence is a tool like a brush, and whether or not to create high-quality works depends entirely on the creator himself. Moreover, if the cost of video-generated AI such as Sora can be greatly reduced, it will be more likely for small teams to produce high-quality film and television works.

Yao Jinli is at the shooting scene.

　　Haoge:It does provide this possibility, and AIGC can help these creators complete some trivial work more efficiently, saving time and cost. For example, artificial intelligence generates virtual scenes, characters and special effects, or carries out automatic editing and post-production.

　　However, to produce high-quality film and television works, not only technology is needed, but also many other aspects of support, such as excellent scripts, excellent directors and actors, professional production teams and so on. In addition, the market competition is fierce now, and it is not easy to attract the audience and achieve success.

　　However, the development of AIGC undoubtedly brings more opportunities and challenges to the film and television industry, which makes film and television production more popular and gives more talented and creative people the opportunity to show their works. At the same time, it may also encourage traditional film companies to innovate and enhance their competitiveness to cope with the new market environment.

Using human "soft skills" against AI

　　Global magazine: Will artificial intelligence make the film and television industry a more competitive industry? Are you worried about the future of the industry and being replaced?

　　Haoge:I think artificial intelligence may make the film and television industry more diversified and provide opportunities for more creators to show their stories and ideas in new ways and styles. At the same time, artificial intelligence may also bring more innovations and experiments to promote the development of the film and television industry. Of course, with the popularization of technology and more people entering this industry, the market may become more crowded. But competition can also stimulate creativity and improve the quality of works, forcing practitioners to constantly improve their skills and creativity.

Hao Ge’s Stills of "Wind Cutting Knife"

　　I am not very worried about the future of the industry, because the development of technology will always bring changes and opportunities, and the film and television industry has always had strong adaptability. As practitioners, we should pay more attention to and actively respond to possible problems and ensure the diversity and quality of content.

　　Yao Jinli:I have completely watched the short videos released by Sora for the first time, and I have also read the text descriptions of each video. Judging from the completion of a single lens or a single group of lenses, the effect is undoubtedly very shocking. Although there are great problems in the perspective, model details and behavior logic of some shots, they are not hidden. Judging from the authenticity of the picture, the degree of color reproduction, the fineness and fluency of the picture material, Sora’s completion is amazing. Moreover, the video released at present basically restores the lens movement in most film and television shooting, and the effect is very good.

　　The only drawback is that the current video camera movements are relatively smooth and slow, and there are no fast, dynamic and intense shots. Perhaps Sora’s current computing power has not been reached, or there may be problems with the input text description, and no professional film and television practitioners have been asked to make a more detailed and specific description. For example, some text descriptions use professional film and television words such as "close up", "cinematic", "35mm film" and "depth of field", but there is obviously a lack of more specific descriptions.

　　As for whether you will be worried about being replaced, it depends on how much room for improvement Sora has. When advertising still life, the "accuracy" of the appearance of the object is a very important standard. Judging from the video capability of Sora currently known, the "accuracy" of the restored product is obviously far from enough. In the future, whether Sora can improve these abilities will determine whether the trade union will eventually be replaced.

　　Luo Wei:In recent years, the new products in AIGC field have emerged one after another, and their functions have become increasingly powerful, which has brought a lot of survival crisis to practitioners in many industries. The New York Times recently published an article entitled "When your technical skills are eclipsed, your characteristics as a human being will be more important than ever". The authors anish Raman and Maria Flynn pointed out that although AI is threatening, people should not be too anxious about it. On the contrary, the development of AI will highlight people’s unique value. So, what are the advantages of human beings compared with AI? What skills are particularly important?

Luo xian’s work photo

　　The article pointed out that technical skills and data skills have been highly sought after for decades, but now it seems to be one of the most vulnerable skills to AI progress. The interpersonal skills that we have long underestimated as "soft skills" are likely to be the most lasting. This is a hopeful sign that AI may create a working world that relies more on "human ability" than less.

　　Minosh shafiq, president of Columbia University, once said, "In the past, work was related to muscles. Now they are related to the brain, but in the future, they will be related to the mind. "

　　Knowledge method is the focus of artificial intelligence, and good film and television creation needs human consciousness, perception and the connection between hearts. The really good art is the art with soul. The photographer’s new connection with the world and his own perception are the sharp weapons that can resist AI at present.

　　In 2023, there were two important exhibitions about AI in China, namely "Emergence AI Image Exhibition" curated by Ye Wenming and "Out of Nothing: AI Image Art Award Exhibition" curated by Luo Dawei. Ye Mingwen selected a series of works by six AI creators as the main exhibition, and invited 108 photographers from all over the country to participate in the generation of "My First AI Image" as a parallel exhibition.

　　Ye Mingwen concluded, "Photography is a noble manual work. News, documentary and scenery will not be affected by AI at all. Photography requires you to take a camera to observe, occupy a position, choose a picture and walk far away. AI belongs to imagination and intelligent interaction, mainly brain development, which is essentially different from photography that is put into reality. The existence of AI has set off the preciousness of’ photographic behavior’ and promoted the transformation of photography itself. "

　　The exhibition curated by Luo Dawei explores the intersection of contemporary art and artificial intelligence, and how this intersection redefines the boundaries of creative expression. This exhibition is not only an exploration of the art of AI generation, but also an opportunity to peek at the unique cooperation between artificial intelligence and artists. The audience is thinking: Are the displayed works just the products of big data and algorithms, or do they carry deeper thoughts and emotions? Is it a redefinition of artistic creation, or is it just an extension of the creative process?

The film and television elitism is being dissolved.

　　"Global" magazine: When AI technology broke out and superimposed video creation on social media, how do traditional film and television people view the relationship between film and television and the times?

　　Luo Wei:With the birth of Sora, we are moving towards a new unknown in the AI ? ? era. These changes can be traced back to the social media era. Various social media applications in smartphones have become our daily tools. There is a large amount of image information spread behind various social activities. In this era of image explosion, photography has become a new daily expression and writing, and images are extremely powerful and unforgettable. In this subtle process, our photography behavior is forming new habits.

　　AI brings a brand-new stage of image generation, viewers have more choices, the way people watch is changing, the group world is being dissolved by technology, and a new world is emerging. In this new world, individuals have more and more energy and your friends become stars. Through the internet, everyone can become a photographer and a film and television person. No one knows what will happen in the future, but we see that many visual artists at home and abroad have responded to this question in their own ways: how to create in the era of social media?

　　Taking photography as an example, it has reached a very classical era. The daily photography leads to the disappearance of elite photography as a visual art creation, or at least it is undergoing profound changes. So in this context, photographers need to reflect on the meaning of the original industry and work. AI forces us to rethink our relationship with the times, photography with the times, and photography with us.

　　We still don’t know what impact this change will bring, but one thing is certain, the times are constantly evolving, and the new photography in the AI ? ? era must not be a photo on the wall in the traditional sense, but it may be a device, a video, a performance art and so on. Photography can be a variety of media and materials, and its appearance is no longer single, but its internal logic is still about photography itself. Is photography over? In the article "Photography Crisis and Challenge in the Age of Social Media", Cai Meng, a professor at the Central Academy of Fine Arts, pointed out: "You must accept the reality that photography that may be activated is no longer the original appearance. It is no longer photography in the physical and virtual sense, but has become an abstract photography thinking and concept, or a certain soul and spirit."

　　Maybe one day in the future, as action art marina abramovic said, we will live in a world without any art. There will be no entity in that world, and human beings will be in a highly conscious level. Under such a strong mental state, we can transmit our ideas to others without using entities as a medium.

　　BEIJING, Beijing, July 28 (Wu Tao) On the 27th, the three major operators announced that they would completely cancel the domestic long-distance roaming charges for mobile phones from September 1. This means that domestic roaming charges for mobile phones that have been implemented in China for more than 20 years will become history. Who will benefit after cancellation? What impact will it have on operators’ operations? Zhongxin. com interviewed relevant experts for this purpose.

　　Long-distance roaming charges for domestic mobile phones will be cancelled after more than 2 years.

　　On July 27th, Yang Jie, Chairman of China Telecom, announced at the 9th "Tianyi Intelligent Ecology Expo" that from September 1st, China Telecom will completely cancel the domestic long-distance roaming charges for mobile phones, which is one month ahead of the plan at the beginning of the year, and it is expected to benefit 80 million users.

　　Subsequently, China Unicom and China Mobile announced that they would completely cancel the domestic long-distance roaming charges for mobile phones from September 1st, which was implemented one month earlier than originally planned on October 1st. On March 6 this year, three basic telecommunications companies said that they would officially cancel the long-distance roaming charges for domestic mobile phones from October 1.

　　The reporter checked the information and found that roaming charges can be traced back to the 1990 s and have already been generated during the mobile phone period. In 1990s, China set up a "roaming fee" similar to tariff for mobile phones used across regions.

　　This year, the three major operators have already begun to cancel the long-distance roaming charges of domestic mobile phones in advance. On July 25, Zhang Feng, spokesperson and chief engineer of the Ministry of Industry and Information Technology, said that regarding the cancellation of domestic long-distance roaming charges for mobile phones, the Ministry of Industry and Information Technology continued to push the three basic telecommunications companies to speed up their work in accordance with the principle of ensuring that the work is in place and striving for early implementation. "The three companies are making every effort to promote system transformation and other related work, and strive to achieve their goals ahead of schedule."

　　The reporter noted that the official plan to cancel the domestic roaming fee for mobile phones began in 2015. On July 6, 2015, the relevant person in charge of the Ministry of Industry and Information Technology said at the press conference on "speeding up and reducing fees" that "the Ministry of Industry and Information Technology is currently studying and exploring the possibility of canceling roaming charges."

　　What is the impact on ordinary consumers?

　　According to the data of the Ministry of Industry and Information Technology, by the end of June 2017, the total number of mobile phone users in China reached 1.36 billion. Who will be affected by the cancellation of domestic long-distance roaming charges by the three major operators? Will the user’s phone bill drop?

　　Xiang Ligang, an expert in communication industry, said in an interview with Zhongxin. com that the users who really benefit from it are mainly some old users, and the impact on ordinary consumers is actually very small.

　　"There are two main reasons: First, many new packages sold by the three major operators are ‘ Long-term market integration ’ (Long-distance, local calls and roaming are the same price), and these packages do not care about long-distance roaming; Second, for a period of time, a large number of users are converted into 4G users at high speed, that is, from old users to new package users. " Xiang Ligang said.

　　There are data to support this view. According to the latest data from the Ministry of Industry and Information Technology, in the first half of this year, 2G and 3G users continued to switch to 4G users, and 4G users maintained steady growth, with a cumulative net increase of 118 million, reaching 888 million, accounting for 65.1% of mobile phone users.

　　Ma Jihua, an analyst in the telecommunications industry, analyzed in an interview with Zhongxin.com, "There is one kind of users who will benefit, that is, users who use local packages may spend less in the future, but they will not get much light, because the reason why they use local packages is because the demand for long-distance roaming is not great."

　　What is the impact on the three major operators?

　　What impact will this policy have on the three major operators after its implementation? Will its income decline? According to Xiang Ligang’s analysis, the impact is very small. Long-distance roaming charges are originally a management tool of the three major operators. Now, the voice business income of the three major operators is shrinking, and the proportion of total revenue is also decreasing. Therefore, the cancellation of long-distance roaming charges has little impact on the income of the three major operators.

　　Ma Jihua holds the same view. He believes that although the policy will have a little impact on the income of the three major operators, it is not too big. "The three major operators can fully withstand it, and the voice services of the three major operators have also continued to decline. In the future, the income will mainly depend on traffic."

　　According to the data of the Ministry of Industry and Information Technology, from January to April this year, the voice business income of the three major operators accounted for 19.6% of the telecom business income. By the middle of the year, that is, from January to June, the proportion dropped to 19.4%, down 7.1 percentage points from the same period of the previous year.

　　Contrary to this, the traffic revenue of the three major operators is growing rapidly. In the first half of the year, the revenue of mobile data and mobile Internet services of the three major operators reached 274.6 billion yuan, up 29.6% year-on-year, accounting for 42.6% of the revenue of telecom services, driving the revenue of telecom services to increase by 10.3 percentage points.

　　China Daily Online, November 25th-Filial piety is a simple word, but it naturally has a temperature. It is a person’s beautiful and gentle initial heart, and it is also the source of strength for thousands of children to repay their parenting. There are countless stories about filial piety worth sharing. Looking back on the past, "Zi Lu Fu Mi", "Lu Ji Huai Ju" and "Huangxiang Fan Pillow" … … These are all ancient children’s actions to interpret what is called "filial piety". Back to the present, there are still many filial sons and daughters in this society. Recently, the story of a filial daughter in Junlian, Yibin, Sichuan Province not only touched the hearts of Chinese people, but also attracted the attention of overseas media.

Cai Chengcheng taught his mother to read. Source: China Daily Author: Zhang Xinkai

　　Hong Kong’s South China Morning Post reported that this sensible little girl named Cai Chengcheng is ten years old this year. When she was six years old, her mother, Li Chen, had a sudden cerebral hemorrhage. After waking up from a coma, she lost her memory, and her intelligence was only equivalent to that of a child of several years old. Because Cai Chengcheng’s father has to run a small shop to pay his wife’s medical expenses, he goes out early and returns late every day. And my brother Cai Lingzhi has just entered high school, and the course is tight, so he can’t help his sister share the heavy responsibility of taking care of his mother. The heavy burden fell on Cai Chengcheng’s tender shoulders. Taking care of her mother, teaching her to read, write and speak, supervising her to take medicine, and assisting her to complete physical training for rehabilitation have become the "daily compulsory courses" for this little girl. She has become her mother’s intimate partner, literacy teacher and rehabilitation nurse … …

　　Although the burden of taking care of her mother is heavy, Cai Chengcheng has no complaints. "When I was a child, my mother taught me to read with a literacy card. Now I teach her. I combine the Chinese characters that I taught my mother with my favorite animals and foods to enhance my mother’s interest. " Cai Chengcheng used literacy cards and associative memory to help his mother deepen her memory. When she taught "Apple", she brought an apple to her mother to smell and recognize ‘ Rabbit ’ Word, let mother hold a rabbit. Cai Chengcheng said in an interview with the media.

　　The report pointed out that after four years, under the careful care of Cai Chengcheng, her mother has been able to help look after the shop and do simple work, and her body is gradually recovering. In these four years, although Cai Chengcheng spent a lot of energy to take care of her mother, she still got excellent grades and served as a student cadre in the school, which was deeply loved by everyone. Cai Chengcheng’s deeds of taking good care of her mother spread, and she won honors such as the third filial piety and virtue teenager in Yibin City, the good teenager in the new era in Sichuan Province, and the candidate of "Looking for the most beautiful filial piety teenager in 2018" by the Central Radio and Television General Station.

　　In addition to the South China Morning Post, Singapore’s Straits Times also reported Cai Chengcheng’s deeds, affirming her persistence in taking care of her amnesia mother for four years. Malaysia’s Star also reprinted the report of South China Morning Post, and actively conveyed Cai Chengcheng’s sincere and pure feelings of filial piety.

　　The story of this little girl also attracted the attention of Chinese and foreign netizens, and everyone cheered for her.

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.

Pineapple is a very common fruit food in life, which contains nutrients that can bring many benefits to health, and also has the function of losing weight. So what are the ways to lose weight? How delicious is it to use pineapple to lose weight? Using pineapple to lose weight also needs to master the method. Let’s learn more about how pineapple is delicious and can lose weight.

1. The slimming effect of pineapple.

Pineapple is sweet, slightly sour and flat in nature, and has the effects of promoting fluid production, quenching thirst, moistening intestines, relaxing bowels, promoting diuresis, reducing swelling, removing fat and losing weight. Studies have proved that pineapple has a good weight loss effect. Because pineapple contains pineapple enzyme, it can decompose protein and effectively hydrolyze fat, especially it can help protein digestion of meat, reducing the body’s absorption of fat. Pineapple is rich in cellulose, which can also effectively relieve constipation and is good for losing weight. Although pineapple has a good weight loss effect, its enzymes are easy to damage the oral cavity membrane. Pay special attention when eating pineapple. It is best to soak it in salt water before eating it. Besides, don’t eat too much at a time.

2, pineapple diet

1. Braised bitter gourd with pineapple

Ingredients: 1 bitter gourd, half pineapple, half carrot, 1 tsp sugar, a little salt.

Practice: Wash bitter gourd and slice it, cut pineapple meat into small pieces, and cut carrots into pieces; When the pot is hot, add a little oil, add bitter gourd slices and carrot slices and stir fry; Pour a spoonful of sugar and stir well; Pour a little water into the pot and stew for 1 minute; Pour in small pieces of pineapple and stir well; Cook for about half a minute and add a little salt.

2. pineapple rice

Ingredients: glutinous rice or rice, fresh pineapple, rock sugar, almond and raisin.

Practice: Soak the glutinous rice with clear water one day in advance, and pay attention to changing the water during this period to keep the glutinous rice fresh and clean; Cut off the top of fresh pineapple, carefully remove the pulp and juice inside with a spoon, and be careful not to dig it; Drain the glutinous rice, add appropriate amount of pulp and fruit juice, mix well, add 3-4 crystal sugar and appropriate amount of raisins, and add them to the previously dug pineapple; Put the pineapple in a steamer, put it in cold water, heat it in water, turn it to medium heat after the steamer is aerated, and steam it for about 30 minutes until the glutinous rice is completely cooked. Mix it up and down before eating, and sprinkle a proper amount of chopped almonds according to your own preferences to improve the taste.

3. pineapple hawthorn crystal jelly

Ingredients: 8 grams of hawthorn, pineapple, agar, 500 ml of cold water, and appropriate amount of sugar.

Practice: Dice pineapple, remove the core of hawthorn, and then soak in water to prevent oxidation; Boil 3.8 grams of agar in about 500 ml of cold water, add appropriate amount of sugar and keep stirring; Divide agar water into two halves, add diced pineapple into one half, heat it, and then pour it into a mold for cooling. After the hawthorn agar solution is mixed, it is neatly arranged in a container and poured into the solution. After the temperature of the soup drops, put it in the refrigerator to cool, and then pour it with sweet osmanthus.

4. pineapple apple juice

Ingredients: half a pineapple and five big apples, which is the amount of squeezing one liter of juice.

Practice: peel and slice the pineapple, soak it in salt water for 15 minutes and then rinse it off; Squeeze pineapple into juice with a juicer. Pour out the pineapple juice and clean the juicer, then juice the apples. Finally, mix apple juice and pineapple juice.

5. pineapple strawberry fruit tea

Ingredients: half a pineapple, several strawberries and a small bag of black tea.

Practice: peeled pineapple and diced, washed strawberry and cut in half; Put the diced pineapple and strawberry in the teapot; Add black tea bag, soak in boiling water for 10 minutes and enjoy. If the tea is not too hot, add some honey to taste better.

6.pineapple juice

Ingredients: 200ml pineapple juice, 100-150g strawberries, a fresh orange, half a lemon, one teaspoon of honey and four tablespoons of vanilla ice cream.

Practice: Take the container for ice treatment, pour pineapple juice into the frozen layer, and cool for 45 minutes. During the waiting time, peel the pineapple and cut it into pieces, clean the strawberry and cut it into pieces, put it in a blender, juice the orange and half a lemon, add honey and stir well. Add vanilla ice cream and stir briefly until all the mixture is uniform.

Warm reminder: don’t be afraid of trouble, eat too much raw pineapple directly. On the one hand, pineapple pulp is irritating, which is easy to reduce the taste and stimulate the oral mucosa; On the other hand, it is easy to produce bromelain, and people who are allergic to this protease will have itchy skin and other symptoms.

　　How did the virus originate? What are scientists doing in developing drugs against Covid-19? It is the top priority for Chinese researchers to develop effective clinical drugs for Covid-19, improve the cure rate and reduce the mortality rate. On February 15th, Zhang Xinmin, director of the Biological Center of the Ministry of Science and Technology, introduced that the drug screening and treatment program had made positive progress at the press conference held by the the State Council Joint Prevention and Control Mechanism on the latest progress of drug research and development and scientific research in Covid-19. The Ministry of Science and Technology organized a national excellent scientific research team to screen more than 70,000 drugs or compounds by computer simulation screening and in vitro enzyme activity test. At present, The scientific research team has focused on a few drugs, and a number of drugs, such as chloroquine phosphate, lundixivir, and farpiravir, have successively carried out clinical trials. At present, some drugs have initially shown good clinical efficacy. This issue focuses on the origin of the virus, drug research and development, and psychological anti-epidemic.

　　The structure of most viruses is very simple. Basically, it is a shell made of protein wrapped with some genetic material, which is no different from dead things at ordinary times. Once infected cells, they inject their own genes into the host cells and use the host cells to replicate themselves to produce new viruses. Is the virus a living thing? Where did they come from? Below, let’s take a look at three hypotheses about the origin of the virus.

　　Hypothesis 1 Ancient macromolecules Some macromolecules, such as RNA, DNA and protein, begin to replicate themselves independently or cooperatively, and this stage can be called "molecular life". However, in a peaceful molecular life, there is a different kind, that is, some molecular life, including LUCA, the latest common ancestor of all living things, which has developed a structure that has changed the law of life, that is, cells. Cells with membrane structure can better protect delicate core macromolecules such as RNA and protein, which greatly enhances the adaptability of these organisms, which means that they will rub their original molecular life on the ground. There is a hypothesis (The Virus-First Hypothesis) that the virus is the "adherents" of the primitive molecular life world. This hypothesis was once very popular, after all, the structure of viruses is so simple, even crude, and their differences from cell life are so great.

　　Some viruses can form crystals after purification, which is unimaginable for cell biology. More solid evidence comes from "Virusoid", which is an RNA molecule. Pseudovirus can’t infect cells directly, but it can infect viruses. To be exact, it can copy itself and spread itself by hitchhiking when some viruses infect cells, which can cause some diseases such as human hepatitis D.

　　Hypothesis 2 The gene of "defection" Genes can also defect? Yes, in The Progressive Hypothesis, genes will do anything to keep themselves alive.

　　There is a small circular DNA called "plasmid" widely in bacteria. These genes are basically a group of wage earners and temporary workers. Bacteria can absorb them from the environment for their own use at any time, and they can also drive them away at any time.

　　In many bacteria, in addition to their original DNA, there are often some small fragments of circular DNA, which are called plasmids. So in the long evolution, some plasmids learned one thing: we should not work all our lives! These plasmids changed from wage earners to wage earners, which in turn hijacked their bacterial boss and took away all the nutrients of bacteria to replicate themselves. Over time, some plasmids become viruses.

　　Bacteria often suffer from a kind of virus infection called "phage". Some people think that phage comes from plasmid. The cells and bacteria of human beings and all animals and plants are very different. We all belong to "eukaryotes". There are no plasmids like bacteria in the cells, but there are still some genes waiting to move. They refused to stay on the chromosome, but jumped around in the nucleus, running to this chromosome for a while and running to that chromosome for a while. However, these naughty genes do have a name of sage like type — — Transposon (transposon)

　　According to the detection of molecular biology, many transposons have very similar gene sequences to viruses, and the mechanism of integrating themselves into the chromosomes of host cells is also highly similar. In particular, the "Retrotransposon" among them is almost as similar as some viruses, and the only difference is that these transposons cannot migrate from cell to cell like viruses.

　　However, the origin of viruses is still confusing here, because they don’t follow the evolutionary model of general organisms at all.

　　The general process of virus infection is: inject your own genes into the host cells, then use the host cells to copy your own genes, and make all kinds of materials needed to construct virus particles. Finally, manipulate the cells to package all parts of virus particles together with the virus genes into new virus particles and release them to infect other cells. But in this process, the virus is exchanging genes with various organisms all the time.

　　For example, when a virus directs a host cell to package virus particles, it sometimes packages some host cell DNA, or accidentally leaves a little bit of its own gene in the host cell. There is a gene in mammals to prevent the maternal immune system from attacking the fetus, that is, a virus accidentally landed in our cells more than 100 million years ago. When the virus spreads across species, it often leads to the transfer of genes from one species to another.

　　Hypothesis 3 Decaying cellular organisms. After entering the 21st century, a series of discoveries began to make scientists more aware that there are other possibilities for the origin of the virus.

　　In 2003, scientists discovered a very unreasonable virus — — "Mimivirus", the size of this virus has reached 0.4 to 0.5 microns, which is almost the same as bacteria under the microscope. The coronavirus that caused this epidemic is considered to be a relatively large type of virus, and its size is less than 0.1 micron.

　　In 2008, scientists discovered the second big virus, and named it "Mamavirus". Since then, one kind of "Giant Virus" has appeared in human vision one after another. By the time Pandoravirus was discovered in 2013, the record of the largest virus was even more than 1 micron.

　　Pandora virus, the largest known virus, looks almost the same as a bacterium.

　　Since then, the boundaries between viruses and some single-celled organisms have become blurred. For example, the structure and genes of Bacteroides virus are very similar to those of a single-celled organism called archaea. The only difference is that Bacteroides virus has lost a part of the key genes that independently complete cell division, so it has to parasitize in the cells of other organisms and use the cells of the host to grow and reproduce.

　　So there is the third hypothesis of the origin of the virus (The Regressive Hypothesis), which holds that the virus is essentially a degenerate creature. Some single-celled organisms gradually degenerate most of their cell structures in the long-term parasitic life, and finally become this "living dead" general appearance, and the flow like bacteroides virus is an archaea that has just begun to degenerate.

　　Why do deadly viruses always come from wild animals? Let’s analyze it from the perspective of evolution.

　　The "best" virus does not cause too serious symptoms (otherwise it will kill the host itself), but it should not be too gentle (after all, the host is often infected with other viruses at the same time, so it is still necessary to grab resources). Therefore, in the long evolution, this game will promote the virus to finally reach a certain tacit understanding with the host. For example, human beings and rhinoviruses that may cause the common cold belong to this relationship.

　　However, the virus will mutate, and some mutations will cause the host of the virus to change. Without the tacit understanding of long-term running-in between the virus and the new host, there will be the problem of "not paying attention to it", and some of them will bring fatal diseases to the host.

　　In the long-term evolution, human beings have reached a perfect tacit understanding with the viruses that accompanied them all the way from ancient ancestors, and the viruses from livestock, such as measles and flu, are not perfect, but they are somewhat tacit, so they rarely cause serious epidemics. Only the virus from wild animals has nothing to do with human beings, so almost all the diseases that caused the great plague came from wild animals. Therefore, I hope everyone can stay away from wild animals, including stray animals, and don’t raise or eat wild animals.
