BEIJING, Dec. 22 (Reporter Cheng Chunyu) Today, the Ministry of Industry and Information Technology announced ten major events in 2017: new achievements were made in the full implementation of "Made in China 2025", the domestic long-distance roaming charges for mobile phones were completely cancelled, and the domestic large aircraft C919 successfully made its first flight.

　　New achievements have been made in the full implementation of "Made in China 2025"

　　In 2017, the vertical linkage and horizontal collaborative working mechanism of "Made in China 2025" became more and more perfect, the implementation of five major projects progressed steadily, the "Made in China 2025" national demonstration zone was launched, and a number of major landmark projects and projects were successively implemented. Add three national manufacturing innovation centers: information optoelectronics, printing and flexible display, and robots; 97 projects carried out pilot demonstrations of multi-field and multi-mode intelligent manufacturing; A number of high-end equipment innovations such as the "Fuxing" Chinese standard EMU with a speed of 350 kilometers per hour are constantly emerging, and the results of service-oriented manufacturing are beginning to show.

　　Domestic long-distance and roaming charges for mobile phones have been completely cancelled.

　　The three tasks of "canceling all domestic long-distance and roaming charges of mobile phones during the year, greatly reducing the access charges of private Internet lines for small and medium-sized enterprises and reducing the international long-distance telephone charges" have been overfulfilled ahead of schedule. On September 1st, the three basic telecommunications companies completely canceled the domestic long-distance and roaming charges for mobile phones. Small and medium-sized enterprises’ private line tariffs have been greatly reduced, with the highest drop of international long-distance telephone charges exceeding 90%, the average tariff of mobile Internet traffic dropping to 26 yuan /GB, over 80% of fiber-optic broadband users, and 60% of users’ access bandwidth exceeding 50M.

　　Domestic large aircraft C919 successfully made its first flight.

　　The C919 large passenger plane successfully made its first flight on May 5, 2017 after the final assembly rolled off the assembly line in 2015, realizing the historic breakthrough of the Chinese nation’s century-old "big plane dream". At the same time, a number of high-end equipment have achieved major breakthroughs: the world’s most advanced ultra-deep-water double-rig semi-submersible deep-sea drilling platform "Blue Whale No.1" successfully tested combustible ice in the South China Sea, and the "Fuxing" Chinese standard EMU was officially put into operation on the Beijing-Shanghai high-speed railway. The ARJ21-700 new regional aircraft has safely transported more than 30,000 passengers.

　　Industrial Internet Boosts the Development of Advanced Manufacturing Industry

　　In 2017, the framework of industrial Internet standard system (1.0) was released, and the Ministry of Industry and Information Technology promoted the construction of a number of industrial Internet platforms. A number of new industrial apps were commercialized, and personalized customization, intelligent production, networked collaboration and service-oriented manufacturing models were increasingly enriched. The pilot demonstration of intelligent manufacturing and the special project of intelligent manufacturing have been steadily promoted, and the penetration rate of "double innovation" platform of key manufacturing enterprises is close to 70%.

　　4G(TD-LTE) won the special prize of National Science and Technology Progress Award.

　　On January 9, 2017, the project "Key Technologies and Applications of the Fourth Generation Mobile Communication System (TD-LTE)" promoted by the Ministry of Industry and Information Technology won the special prize of the National Science and Technology Progress Award. China put forward and dominated the international standard of TD-LTE, which achieved a breakthrough in the whole industrial chain of mobile communication and built the world’s largest 4G network, with the total number of 4G users in China reaching 962 million. Positive progress has been made in the research and development of 5G technology, and the second phase of the experiment has been completed. The mid-band frequency planning has been released first, and technologies such as network architecture have become international standards. Fifteen 5G field test base stations have been built.

　　Revision and promulgation of "People’s Republic of China (PRC) Small and Medium-sized Enterprises Promotion Law"

　　The revised SME Promotion Law of People’s Republic of China (PRC) will be officially implemented on January 1, 2018. The new law promotes the effective policies in recent years into laws, standardizes the policies related to fiscal and taxation support, and improves the measures related to financing promotion, especially standardizing administrative licensing matters, reducing the burden on enterprises, simplifying tax collection and cancellation registration procedures for small and micro enterprises, and creating a good environment for the development of small and medium-sized enterprises.

　　"Double Points Policy" Helps the Healthy Development of New Energy Vehicles

　　On September 27, 2017, the Ministry of Industry and Information Technology and other five departments jointly issued a double-point policy, and at the same time set up two points, namely, the average fuel consumption of enterprises and new energy vehicles, and established a point trading mechanism. Enterprises independently determined the negative point compensation method to achieve two goals of energy saving and consumption reduction and promoting the development of new energy vehicles. In 2017, China’s new energy automobile industry developed rapidly, with both production and sales exceeding 700,000 vehicles, with the number of vehicles exceeding 1.7 million, ranking first in the world for three consecutive years.

　　Expanding and upgrading information consumption and continuously releasing domestic demand potential

　　In the first three quarters, China’s online retail sales exceeded 4.8 trillion, a year-on-year increase of 34%, accounting for 14% of the total retail sales of consumer goods. New intelligent hardware, virtual reality and other products emerge in an endless stream, and new models and formats such as mobile payment and sharing economy are accelerating. It is estimated that the annual information consumption scale will reach 4.5 trillion yuan, accounting for 10% of the final consumption expenditure.

　　The cancer "strip steel" in the iron and steel industry has been completely cleared

　　2017 is a crucial year for steel de-capacity, exceeding the government target of 50 million tons of steel de-capacity for the whole year. Concentrate on banning strip steel, which has plagued the development of the industry for many years, and realize the comprehensive clearing of 140 million tons of strip steel, effectively reversing the situation that "bad money drives out good money" in the steel industry.

　　Integration of defense and civilian technologies’s development of national defense science, technology and industry has achieved stage results.

　　Beidou-3 began global networking, and the accuracy of services in the Asia-Pacific region reached the meter level; The military industry has taken a new step in opening up, and the revised catalogue of scientific research and production licenses for weapons and equipment has been reduced by 62% compared with the original one. More than two-thirds of the main units that have obtained the licenses for the development and production of weapons and equipment are civilian units, and the level of "civilian participation in the army" has been upgraded from general supporting products to overall and sub-systems; The sharing of military and civilian resources has been deepened, and more than 3,000 major test equipment and facilities for national defense science, technology and industry have been released to the society.

　　A round football has attracted wide attention. The news that Shen Haixiong, director of China Central Radio and Television Station, and Gabriele Glavina, president of the Italian Football Association, signed a memorandum of understanding on cooperation in Rome has quickly fermented in the global media. Small football, attracting attention, has become one of the hot spots of multinational media.

　　In order to implement the consensus of the heads of state of China and Italy on deepening mutual trust and pragmatic cooperation in various fields, and promote the development of football career and the spread of football culture in the two countries, on March 24th, China Central Radio and Television General Station and the Italian Football Association decided to carry out all-round strategic cooperation. According to the intention reached by both sides, Serie A is expected to enter China normally in the next three years.

　　"Football has once again become a bridge between different cultures."

　　The Associated Press (AP) published an article entitled "Italian Football Federation Signs Deal with Chinese Government", saying that the Italian Football Association signed a comprehensive memorandum with the government of China to promote the development of football in the two countries. Gabriele Glavina, president of the Italian Football Association, said: "Football has once again become a bridge between different cultures." The Washington Post, Miami Herald, ESPN (Entertainment and Sports Network) and other media all forwarded the report of the Associated Press.

　　Agence France-Presse reported the signing of the contract between the Italian Football Association and the government of China. The report emphasized that the president of the Italian Football Association said "this is a historic meeting and extremely important" after meeting with Shen Haixiong, director of the Central Radio and Television Station. Reuters reported on the topic "Italy will discuss staging Serie A matches in China".

　　An article published on the Financial Times website was titled "Top Italian Football League is negotiating to host a game in China". After this report was forwarded by the international mainstream media, it caused widespread public concern.

　　The news that China and Italy signed a memorandum of understanding on football exchange has attracted great attention from Italian media. Almost all mainstream media, including the Italian National Radio and Television Company, La Corriere dello Sport, Ansa, La Republica, Italian Football Association official website and Tgcom24 news channel website, reported it in a prominent position or at an important time.

　　The Italian National Radio and Television Company tweeted that the Italian Football Association hopes to carry out all-round cooperation with China, including Serie A events, through the memorandum of cooperation signed with the Central Radio and Television General Station, the largest media group in China.

　　The Evening Post published an article saying that this is a very pragmatic memorandum. The cooperation between CCTV and the Italian Football Association will help to promote the spread of Italian football culture in China, promote cooperation in related industries, jointly improve the football level of the two countries, and promote comprehensive cooperation and exchanges including competition cooperation, cultural exchange, sports medicine cooperation and player coaching.

　　Official website, the Italian Football Association, released a message immediately after the signing of the memorandum, saying that the memorandum was aimed at promoting the development of football in China and the spread of Italian football in China. Glavina, president of the Italian Football Association, believes that this is a historic meeting. This dialogue with the director of the Central Radio and Television General Station can not only further strengthen the exchanges between Italy and China in football and culture, but also breed new opportunities for cooperation.

　　The Italian newspaper La Repubblica published an article saying that the signing of the memorandum will help Italy to better spread its football culture in China. In the near future, maybe we can watch Lazio-Napoli match in China.

　　On March 24th, Russian, French, German, Japanese, Brazilian, Portuguese, Kazakstan, Thailand, Nepal, Canadian and other countries published a draft of "The Memorandum of Understanding on Cooperation between CCTV and Italian Football Association is expected to enter China normally", which blew the football wind in China.

　　Serie A is expected to enter China normally, and this news has also been forwarded and praised by many media in China. Mainstream media such as People’s Daily Online, Xinhuanet, Chinese Government Online, Zhongxin.com, and World Wide Web believe that China and Italy will organize training for football technicians, football club management talents and schools, organize national football teams of the two countries to hold friendly competitions in each other’s countries, carry out cooperation in football digitalization and product development, and build a new communication platform for fans and teams of the two countries. Overseas Chinese media such as Hong Kong Commercial Daily, Ta Kung Pao and American Business News also paid attention to the historic significance of this agreement for the first time.

　　People’s Daily, Beijing, October 10 (Reporter Zhang Tianpei) The reporter learned from the Ministry of Public Security that by the end of September 2023, the number of motor vehicles in China had reached 430 million, including 330 million vehicles and 18.21 million new energy vehicles. There are 520 million motorists, including 480 million motorists.

　　According to reports, there were 26.01 million newly registered motor vehicles in the first three quarters, including 18.17 million newly registered vehicles, up 4.4% year-on-year. The newly registered vehicles in the first quarter, the second quarter and the third quarter were 5.88 million, 5.87 million and 6.42 million respectively.

　　By the end of September, the number of new energy vehicles in China reached 18.21 million, accounting for 5.5% of the total number of vehicles. Among them, the number of pure electric vehicles is 14.01 million, accounting for 76.9% of the total number of new energy vehicles. From the first quarter to the third quarter, 5.198 million new energy vehicles were registered nationwide, up 40% year-on-year, accounting for 28.6% of the newly registered vehicles. Among them, 1.44 million new energy vehicles were registered in the first quarter, 1.709 million in the second quarter and 2.049 million in the third quarter respectively.

　　It is understood that the used car market remained active in the first three quarters. From the first quarter to the third quarter, local public security traffic control departments handled a total of 25.05 million motor vehicle transfer registrations, including 23.31 million motor vehicle transfer registrations, accounting for 93.1%. In recent years, the Ministry of Public Security, together with the Ministry of Commerce and other departments, has promoted the implementation of reform measures to facilitate the registration of second-hand car transactions in different places, which has better promoted the circulation of second-hand cars. In the first three quarters of this year, the public security traffic control department handled 3.805 million transactions of second-hand passenger cars in different places.

　　By the end of September, there were 90 cities in China with more than 1 million cars, an increase of 8 cities over the same period of last year. Among them, 43 cities have more than 2 million cars and 25 cities have more than 3 million cars. Beijing, Chongqing and Chengdu have more than 6 million cars, Shanghai and Suzhou have more than 5 million cars, and Tianjin, Hangzhou, Zhengzhou, Wuhan, Xi ‘an, Shenzhen and Dongguan have more than 4 million cars.

　　Editor’s Note: The publicity campaign on the theme of "Chinese Dream: Artisans in Great Countries" was jointly carried out by the National Internet Information Office and the All-China Federation of Trade Unions, aiming at vigorously promoting the spirit of model workers, labor spirit and artisans, creating a glorious social fashion of labor and a professional atmosphere of striving for perfection, giving full play to the demonstration and leading role of advanced model figures, and encouraging more workers, especially young people, to take the road of becoming talents and serving the country with skills.

　　China Youth Network, Beijing, September 29th (Reporter Mou Haokun Intern reporter Wu Boyang correspondent Hasyeti Kasmu Li Shuangxing) Petroleum is the most important raw material in modern industrial society. Everyone’s food, clothing, housing and transportation are closely related to oil and natural gas.

　　For example, a bottle of mineral water on the table, which is put in front of you after water source discovery, mining, purification, bottling and transportation, consumes a third of the oil. If it is fruit juice, the oil consumption will be as much as half a bottle.

　　Before graduating from college, like many young people who have never been to an oil field, Fang Zhigang, a first-class engineer in Tuha Oilfield and a technical expert in China Petroleum Gas Lift Center, thought that once an oil well was drilled, the oil could be ejected or pumped out and then applied to all aspects of our lives. However, when he arrived in the Turpan-Hami basin, he realized that oil is contained in rock sand and needs to be "washed out" again and again by water and polymers.

　　Recently, the reporter followed the theme propaganda activity of "Chinese Dream, Artisans of Great Powers", and learned about the whole process of oil from exploitation, refining to export, as well as the symbolic brand technology of China oil. "Gas-lift oil recovery is an oil recovery method that injects high-pressure gas into the well from the ground and uses the principle of gas expansion to reduce the liquid density in the wellbore and lift crude oil to the ground." Fang Zhigang is an outstanding representative engaged in this technical research and the leader of the gas lift technical innovation team in recent years.

　　"What we are doing is to make oil wells produce high and stable yields."

　　"Facing the long yellow sand and the vast Gobi every day, it’s a bit monotonous and lonely after a long time, but I’m used to it." After graduating from college, Fang Zhigang, a young man from the northeast, came to the northwest of the motherland, which gradually made him feel special about this land in Xinjiang. In his eyes, the vast desert contains infinite possibilities. "If you want to dry oil, you want to choose the place with the most oil fields. The most promising place in the future is Xinjiang." He said.

　　Fang Zhigang went into the gas distribution room to check the gas injection in the gas lift well at the gas lift technical operation site in Jannarol Oilfield (well 2397). Photo courtesy of respondents

　　When he first arrived in Tuha Oilfield, Fang Zhigang came to Tuha Drilling Company for an internship. But the drilling work is a far cry from what Fang Zhigang imagined. Fang Zhigang starts from the construction site every day, lifting drill pipes and removing cuttings. At the end of the day, he is covered with mud and oil. What impressed me the most was that one day a nearby well overflowed and several drilling teams helped to prepare mud. Fang Zhigang and his workmates carried barite powder and poured it into the mud pit in bags. A bag of 25 kilograms, busy from the afternoon until late at night, when the danger is lifted, everyone is tired and paralyzed at the well site.

　　This is the first time that Fang Zhigang experienced heavy physical labor. Later, I heard from Master that overflow is the precursor of blowout, and barite powder mixed with mud is used to kill well and make blowout. If you hold down the well, it will be fine. If you can’t hold down the well, it will be a blowout accident, and the most serious machine will destroy people. At that time, what appeared in Fang Zhigang’s mind was the picture of Iron Man Wang Jinxi jumping into the mud pool, and he also understood the special significance behind everyone’s shoulder-pulling.

　　After the first Spring Festival in Tuha Oilfield, the company informed Fang Zhigang to report to the Institute of Engineering Technology. When he arrived at the Academy of Engineering and entered the gas lift center, Fang Zhigang’s first task was to design a slim hole expandable packer. At that time, Tuha Oilfield used sidetracking technology to bring a number of old wells and casing damaged wells back to life and re-employed. However, there is no matching small diameter packer in China, so the oilfield decided to develop it by itself.

　　When designing the rubber tube, the research team encountered problems. Small size does not have enough bearing capacity, and large size can’t get into the well. Repeated adjustment of the design failed to solve the problem. "It’s like a seesaw, taking care of one end and not caring about the other." Fang Zhigang said.

　　After soaking in the workshop for several days, Fang Zhigang pondered it over and over again. He found that the most serious deformation of the rubber tube was mainly at both ends, and this factor mainly affected the sealing performance.

　　"Can you change the rubber tube from fixed to movable, so as to reduce the risk of damage and improve the sealing performance?" Fang Zhigang’s idea, after implementation, really solved the problem. Master asserted that a single-minded young man can do technology and research.

　　After a period of oil well production, the pressure drop and the output drop, all of which need to be supplemented by artificial lifting to improve the output. In Fang Zhigang’s view, among many artificial lifting oil production methods, gas lift can give full play to the reservoir’s own energy. Under the condition of gas source, gas lift oil production is the first choice and the most economical and effective artificial lifting method in the oilfield. Moreover, gas lift can produce oil in the whole life cycle from the initial stage of production to the final shutdown.

　　With gas lift, wells with insufficient energy for flowing production can produce normally, wells with low production can increase production, and wells with high production can obtain higher production. Fang Zhigang often vividly said to the gas lift team members, "What we are doing is to make the oil well high and stable, make the oil field develop efficiently, and strive to make the oil field younger."

　　"The mountain is climbed step by step."

　　In 2010, Fang Zhigang took over the 48-gas lift technical service of BBA Oilfield in the Middle East, and the biggest problem was gas lift tools.

　　The crude oil in BBA Oilfield has "four highs", high sulfur content, high wax content, high carbon dioxide content and high asphaltene content, which requires high sulfur and corrosion resistance for downhole tools. In particular, the oil well is large in size and high in production, and the diameter of the working cylinder of gas lift valve is required to be 168 mm, while the largest size of Tuha gas lift in the past was only 127 mm.

　　"The diameter has increased by 41 mm, which seems to have only increased by one-third, but the technological difficulty is geometric growth, which is easy to talk about!" It is time-consuming, heavy-duty and difficult to complete the R&D and manufacturing test of tools and put them into field application within one year. When I first took over the task in 2010, many people described it as an "impossible task".

　　"The mountain is climbed step by step, and the ship is shaken out one by one." Fang Zhigang said, "If you don’t do it, you will never succeed."

　　When it really gets started, problems follow.

　　The first is to prevent hydrogen sulfide. Sulfur is the nemesis of metals. Generally, when metal meets hydrogen sulfide, it will produce "hydrogen embrittlement" phenomenon, and the stress will drop greatly, so it is easy to break off. The upper and lower ends of the working cylinder of the gas lift valve are connected with oil pipes, and the diameter is relatively small, while the diameter of the body part is large, which is "small at both ends and thick in the middle" on the whole. In the past, the working cylinder of gas lift valve mostly adopted welding technology, three-stage combination and two welds. However, sulfur has a great influence on the weld, and the sulfur-proof welding process is more difficult.

　　Domestic factories have found one after another, but they can’t guarantee sulfur-resistant welding. "Welding can’t be changed to forging!" Forging is not difficult. Just to solve the problems of shrinkage ratio and compression resistance, I don’t know how many times I optimized the structure repeatedly, and finally I had to choose a special-shaped working cylinder similar to an ellipse.

　　Press the hoist to float the ladle, avoiding the welding problem and welcoming the forging test. The special-shaped structure has greatly increased the difficulty of forging, and it is only after half a year of tackling key problems that we have found the top domestic factory in Shenyang.

　　Dozens of such large and small problems have been solved, almost all of which are original solutions. Finally, it’s time to wake up the underground gas lift tools. Whether the gas-lift tools that have been dormant underground for several years can be started normally or not, the gas-lift ceremony of Well 028 affects the hearts of all parties in the oilfield. Although every step of gas lift is carefully calculated and thought out, many original technologies are used to extract oil under such harsh conditions, which is unprecedented in China. "Whether it’s a dragon or a worm, we’ll see." Just like welcoming the birth of a child, Fang Zhigang was both nervous and excited in those days. "I still have the confidence to do my own work!"

　　At 9: 00 am on July 18, 2017, with the opening of the gas injection valve, natural gas was continuously injected into the wellbore. The primary valve is over-gassed, and the secondary valve is over-gassed … … Two days later, the gas lift well entered the normal working state, and the oil well output rose steadily until it exceeded 30% of the initial daily production. The oil field won the environmental protection award issued by the local government, which is the first time that the local government’s foreign cooperation project has won such an honor for decades.

　　"My greatest value is here."

　　In North Trouvat Oilfield (Well 7546), Fang Zhigang (third from left) led the team to go deep into the technical service site to carry out technical services. Photo courtesy of respondents

　　Working in the oil field and serving the domestic and foreign countries by gas lift is the norm in Fang Zhigang, and even the wife who works in the same unit rarely meets it.

　　At the end of 2014, his father, who was far away in the northeast, was critically ill, and Fang Zhigang hurried back to his hometown. When I met my father in the hospital, my condition was so serious that it was no longer suitable for treatment. Father said, "Son, let’s go home." Going home that day, my father died in the middle of the night.

　　I have been working for many years, far away from my hometown, and there are only a handful of days to be with my father. Children want to raise and don’t stay close. Fang Zhigang said that the most regrettable thing is that he failed to convince his father to come to Xinjiang to live together before his death.

　　After the birth of his youngest daughter, he was away on business all the year round. I have a vacation once in a while, but I can’t stay for a few days. When I first met my father, my little daughter felt strange and cried. Go to bed at night and drive straight out. A few days later, I finally got a little hot, and it was time to go again.

　　In 2011, Tuha gas lift entered the Middle East market. As the head of the Middle East project in Beijing, Fang Zhigang is as busy as a top every day. In July, it was the critical moment of business operation, and the two daughters had a high fever at the same time. Three days later, I still have a high fever. The wife was really desperate, so she called Fang Zhigang.

　　Report to the leader, immediately grant leave, and arrange for colleagues in Tuha Oilfield to coordinate vehicles and help take care of them. Fang Zhigang finished the work at hand overnight, and instructed his colleagues. Only then did he fly back to Xinjiang in a hurry and rushed to the hospital. At this time, the child’s body temperature exceeded 40 degrees Celsius, especially the one-and-a-half-year-old daughter, who has been in a coma since she had a fever. The doctor suggested that she be transferred to the hospital immediately. Rushed to Urumqi overnight, the hospital arranged directly into the intensive care unit. Seeing the child with an oxygen tube and a stomach tube, this strong northeast man shed tears.

　　Fortunately, three days later, the high fever eased and the child could open his eyes, so the couple were a little relieved. A week later, the child was transferred to the general ward. Fang Zhigang was ready to put up with his wife’s complaints and scolding, but she didn’t say anything. She understands that most oil families do.

　　A few years ago, some mainland enterprises also offered olive branches with high salaries, hoping to seek common development. Fang Zhigang declined politely. He said: "It is my breath that has made me. My greatest value is here, and the stage for giving full play to my talents is also here."

　　Wu Guanghui, chief designer of Comac C919 and ARJ21, has won the national special prize for scientific and technological progress and the first prize for national defense scientific and technological achievements. A key model won the first prize of China Aviation Industry Corporation I and the first prize of the National Defense Science, Technology and Industry Committee.

　　"Many aircraft parts are made in China and fly in the sky every day. C919 has gone through nearly seven years, and has done a lot of design, calculation and experiments. I am definitely willing to take this plane first. "

　　— — Wu Guanghui

　　These days, in the commercial aircraft test center of China Commercial Aircraft Corporation, the newly-built Zhuqiao test hangar in Pudong is spacious and bright. In the hangar, the landing gear that originally supported the domestic large passenger plane C919 was all put into the landing gear cabin, and three air springs like "jacks" lifted the plane into mid-air. What is going on here is the ground resonance test and modal coupling test of the whole aircraft that must be completed before the first flight, which means that the C919 has officially entered the final sprint stage before the first flight.

　　C919 is a domestic large passenger plane independently designed and developed by China. It is a short-haul single-aisle narrow-body passenger plane with more than 150 seats. In the future, it will compete with internationally renowned commercial aircraft such as Airbus 320 series and Boeing 737 series for orders. The manufacturer China Commercial Aircraft Co., Ltd. recently announced that the C919 plans to make its first flight in the first half of 2017 and will fully launch the wide-body passenger aircraft project. It can be said that after nearly 10 years of hard work, China people’s dream of "big plane" will soon become a reality.

　　① Rigorous test to ensure safety.

　　To fly into the blue sky, a plane must first practice a pair of steel bars and iron bones. For the C919, which carries the dream of a big plane for Chinese people, the significance of the test is even more significant. This is the first large passenger plane made in China, and its safety cannot be lost.

　　For this reason, C919 has undergone a series of tests like "torture". Among them, the 2.5g static test of the whole aircraft started in early November last year is the most severe and significant one since the birth of the C919.

　　This test mainly tests the strain and deformation of the "skeleton" of the body under constant external loading. In layman’s terms, this kind of test is to let the aircraft simulate the stress situation when challenging air flight on the ground, and go beyond the natural limit to verify how much force the aircraft can bear.

　　Before the start of the experiment, the researchers covered the whole body with white adhesive tape, which is a resistance strain gauge that can sensitively measure stress and strain close to the surface of the body, just like doing electrocardiogram for the plane. During the test, the load starts to rise at the level of 5%, and the load must be kept for 3 seconds every time. "The structure must be able to withstand the ultimate load for 3 seconds without damage." Zhou Liang Dao, deputy chief designer of the C919 passenger plane, said that the preparation behind the team took more than 300 days for this short three seconds.

　　With the continuous loading, the aircraft began to show obvious external reflection, and the wing began to tilt up a little. Finally, when the load reaches 100% of the test outline, the wing tip tilts up to nearly 2 meters, which is highly consistent with the strength analysis before the test, which shows that the test is successful and its strong "bones" and body are enough to support flying into the blue sky.

　　This is just a small step in the long March before the first flight of the plane. A passenger plane has to complete 13 static tests in 48 working conditions, including pressurization in the booster cabin, front lifting connection, main lifting connection, whole aircraft condition, vertical tail and rudder, as well as "three-bird test" such as iron bird, copper bird and electric bird and joint test of the whole aircraft system. Therefore, researchers have made independent innovations in system integration experiments.

　　In the comprehensive test hall of Shanghai Aircraft Design and Research Institute, the iron bird test-bed with little difference from the C919 real machine looks like an eagle with wings spread and its tail stuck high. Don’t underestimate this test-bed. Its full name is "Integrated Test-bed for Flight Control Hydraulic System", which mainly tests the landing gear, wings and other mechanical systems of aircraft. In order to ensure the authenticity of the system test, the iron bird test-bed is designed according to the 1:1 ratio of the real aircraft, so that the mechanical installation interfaces of the flight control, hydraulic and landing gear systems are the same as those of the aircraft.

　　Next to the Iron Bird Test Bench, there is also a "Copper Bird" that tests power supply systems such as power generation and distribution, and also restores the real state of the machine to 1:1 for equipment installation. "Iron Bird", "Copper Bird" and the avionics system test called "Electric Bird" will eventually be all connected, thus forming a "three-bird joint test" to simulate the state of the aircraft.

　　In the experiment, researchers conducted a comprehensive test on the aircraft system. Take the avionics system as an example. At most, there are more than 100,000 parameters in a test. These parameters should be tested one by one to find out the possible omissions in the design. "Our goal is not to take the fault to the sky." Yu Shenghui, senior engineer of the General Aerodynamics Department of Shanghai Aircraft Design and Research Institute, said.

　　According to the plan, six testing machines are carrying out joint testing of the whole machine system, and customer service engineering and airworthiness work are also being carried out simultaneously.

　　②C919 is genuine China goods.

　　As the first large passenger plane with completely independent intellectual property rights in China, C919 has been frequently questioned since it was established in 2006: an aircraft whose engine, avionics core processing system and some materials all depend on foreign products or technologies, why should it be said to be "made in China"?

　　In fact, to evaluate the innovation of C919, we may need to draw lessons from a fairy tale named Pony Crossing the River. This story is about a pony crossing a river. A cow next to it said, "The water is very shallow, just without a calf, so you can cross it." But the squirrel in the tree said, "The water is deep and will drown." So, is the river deep or shallow? Finally, the pony got off the river by himself and carefully waded to the other side. It found that the river was neither as shallow as the cow said, nor as deep as the squirrel said. The same is true for the development and innovation of C919. Everyone should not only see the major innovations achieved in the process of aircraft development, but also objectively admit the existing shortcomings.

　　According to international standards, judging whether an airplane is made in China or assembled depends on whether it meets three conditions. 1. Who owns the property right of the whole machine? Second, who is the core team to develop the whole machine? Third, who holds the key link in the development of the whole machine? For C919, the answer to these three questions is China.

　　The person in charge of Comac in China said that the property right of the C919 is owned by Comac in China. The team of Comac in China is the core of the development, and the key links such as aircraft design, final assembly, test flight and sales are in the hands of Comac in China.

　　As for foreign companies providing parts or technology, this is a common thing in the global aviation manufacturing industry. Aviation manufacturing giants such as Boeing and Airbus also use foreign products on many key components when developing aircraft.

　　However, for equipment like engines, the C919 chose the LEAP-X1C engine jointly developed by the United States and France, which is the only foreign starting power device selected by the C919. It should be said that the engine is indeed a major constraint in the development of China’s large aircraft, and it can only be sought from people at present. However, I believe that in 10 to 15 years, China will be able to develop its own advanced aero-engine for large aircraft.

　　③ Have a number of scientific and technological innovations.

　　Experts said that the C919 was completely designed and integrated independently, with outstanding technical indicators. It is the persistent innovation of researchers who have sharpened their swords for ten years that has led to the high-tech C919, which integrates many key technologies.

　　However, what did C919 look like when it was approved as one of the 16 major projects in the national medium-and long-term science and technology planning in January 2006? What difficulties may be encountered in the development? Due to the limitation of western aviation powers in technology introduction, China researchers have no idea and can only cross the river by feeling the stones.

　　In November 2008, the C919 project was launched. A large passenger aircraft joint engineering team composed of 468 experts from 47 domestic and foreign units, plus a large passenger aircraft expert consulting group composed of 20 academicians and experts, started from sketches and gradually sorted out the first batch of 14 special technical research projects that need to be started.

　　Among these key technologies, there are several that must be mentioned. For example, the "supercritical airfoil" that makes airplanes more fuel efficient. A large passenger airliner is an out-and-out "oil tiger". In order to reduce fuel consumption, the wing design of C919 uses a supercritical airfoil, which improves the cruise aerodynamic efficiency by more than 20% and reduces drag by about 8%.

　　Another unique innovation is the adoption of the third generation Al-Li alloy materials. It is the first time in China that the world’s advanced third-generation Al-Li alloy materials are widely used in the main structure of C919. Compared with ordinary aluminum alloy, this lightweight metal material with high damage resistance has greater strength and lighter weight under the same strength, which is very important to realize the weight reduction of aircraft structure and greatly improve the service life of aircraft.

　　In addition, as the "brain" of the C919, the avionics system of the aircraft has realized "giving all the work to the network". Compared with the old version of the network, which was widely used before but had limited bandwidth, the new aviation bus communication protocol adopted by C919 not only has high bandwidth but also shares resources, which means that the signals that originally needed to be transmitted through several cables can now be transmitted by one cable. Experts said that this is like we need to run 10 trains from A to B, but we don’t need to build 10 railways. We only need a set of double-track railways and a reliable signal system.

　　According to Wu Guanghui, the chief designer of C919, the developers have planned 102 key technical problems, and many advanced materials have been applied on a large scale in domestic civil aircraft for the first time. The development process of millions of parts and airborne systems is highly parallel. In order to overcome these technical difficulties, 22 provinces and cities, more than 200 enterprises, 36 universities and hundreds of thousands of industrial personnel participated in the development of C919 large passenger aircraft, and 16 material manufacturers and 54 standard parts manufacturers including Baosteel became suppliers or potential suppliers of large passenger aircraft projects.

　　Recently, a number of ministries and commissions jointly issued the Opinions on Strictly Regulating the Management of Online Game Market, and deployed centralized rectification of online game violations and bad content. Bright pictures/vision china

　　In recent years, China’s online games have developed rapidly and the content forms are constantly enriched. At the same time, it must be noted that the lack of cultural connotation of online games in China is more prominent, some games have a tendency to vulgar violence, and the values of individual works are biased. Recently, the Propaganda Department of the CPC Central Committee, the Central Network Information Office, the Ministry of Industry and Information Technology, the Ministry of Education, the Ministry of Public Security, the Ministry of Culture, the State Administration for Industry and Commerce, and the State Administration of Press, Publication, Radio, Film and Television jointly issued the Opinions on Strictly Regulating the Management of Online Game Market, and deployed centralized rectification of online game violations and bad content, which opened the curtain of online game industry governance nationwide. Taking this industry governance as an opportunity, online games are bidding farewell to the old stage of barbaric growth and welcoming a new era of transformation and upgrading.

　　There is an urgent need to standardize the governance of online game market.

　　To sum up, there are four kinds of problems in online games at present: universal and serious addiction, serious vulgarization of some contents, emphasis on form but light on connotation, and wanton deconstruction of traditional cultural classics and values.

　　Addiction is a major feature that distinguishes online literature from traditional literature, among which online games are the most addictive. Once a netizen suffers from Internet addiction, it will not only consume a lot of time, energy and money, but also seriously damage his physical and mental health. The main users of online games are between the ages of 15 and 25. These teenagers have poor self-control and their minds are not yet fully mature. Once they are infected with Internet addiction, their physical and mental injuries are often very serious.

　　Online games are not only the most addictive, but also the problem of vulgarization is serious. For example, in a popular MOBA online game, most female characters such as Wu Zetian, Xiao Qiao, The Story Of Diu Sim and da ji are scantily dressed, wearing sexy short skirts or long skirts. However, in large MMORPG 3D online games such as "Dragon’s Eight Branches" and "Zhu Xian", the role modeling with erotic and seductive meanings has been brought into full play. In addition to visual pornography, many games even add interactive content, such as the 3D online game "Myth", which has a built-in interactive little game called "Ghost Story", so that players can "experience" the pornographic scene of stealing women and stealing jade by manipulating characters. The above-mentioned vulgar pornographic content can be found everywhere in online games, which is extremely harmful to the physical and mental health of young players.

　　Formalization is also a prominent problem in online games, which is manifested in excessive pursuit of external sensory experience and content almost becoming a vassal of form. Many domestic war games are designed with "skins" that need to be purchased before they can be used, and many games will regularly launch some "limited skins" for short-term sale according to specific festivals. Games such as the glory of the king, Battle Against the Snake, etc. are constantly launching a large number of various "skin" shapes to attract players to spend. No matter what kind of "skin", its function is just to change the audio-visual special effects in the game, which has nothing to do with the content of the game.

　　There are also some games that arbitrarily deconstruct cultural classics and convey wrong values. For example, in a turn-based role-playing game with The Journey to the West as its content, both the demon and the demon are justified, and the inferno becomes an equal force with the Terran and the Fairy, thus the image of "man-eating monster" in the original work is easily dispelled. Another game with the content of "Three Kingdoms" is mixed with many fictional myths and legends on the basis of deconstructing the story of "Romance of the Three Kingdoms". The characters in this game, such as "Yin and Yang Scholars" and "Magician", have supernatural power and can use all kinds of magic. In addition, the excessive deconstruction of history and historical figures is also a common problem in online games. In a popular game, the backgrounds and experiences of all historical figures are deconstructed to varying degrees. For example, Gao Jianli is deconstructed as a wild and uninhibited "genius musician", Di Renjie is endowed with "extremely strong obsessive-compulsive disorder and cleanliness tendency" and other unique personalities, Jing Ke is designed as a sexy female assassin, Huang Zhong is shaped as a gunner who operates a cannon, and da ji is deconstructed as a magic puppet with powers. The above-mentioned question game tells a false story of China, portrays a false image of China, and spreads a wrong view of history, which not only harms users’ physical and mental health,It is also not conducive to the construction of China’s cultural security and soft power.

　　Build a strong position to tell the story of China well

　　The problem of online games has a long history. To fundamentally solve all kinds of problems in the production and communication of online games, we need to start with top-level design, take multiple measures and make comprehensive policies.

　　At present, Tencent, Netease, Sohu, Sina and other private capital or foreign capital-controlled Internet companies occupy the main position on the supply side of online game content in China. While calling on online game enterprises to assume more social responsibilities, in order to fundamentally improve the production pattern of online games in China, we must implement the supply-side reform of online literature and art, and build a number of powerful national teams of online literature and art as soon as possible, and the national teams will intervene and lead the development of online game industry.

　　In order to ensure the core competitiveness of the national team in the online game market, the author suggests to build the first echelon of the online game national team based on the existing state-owned leading online media. For example, people’s network, CCTV, Xinhuanet and other powerful national online media can open up special online literature and art channels, recruit top talents in online game research and development around the world, develop a number of phenomenal online game products with both social and economic benefits, and build a strong position to tell the story of China on the Internet. For the strong private network literature and art production and communication subject, it can be developed into the second echelon of the online game national team by means of acquisition, holding or mixed reform. In addition, we can also acquire, hold or participate in a number of well-known foreign online game R&D teams with leading content production and network technology to form an alliance of the online game national team. The national online game team constructed in this way is conducive to the optimal allocation of various resources, which can not only lead the direction of telling the story of China in Socialism with Chinese characteristics, but also maintain high market sensitivity and creative vitality.

　　The governance of online games can’t treat the symptoms only. To fundamentally solve the problem, we need to establish an institutional mechanism to ensure the green, healthy and sustainable development of online games. The author suggests that legislation on online literature and art should be started as soon as possible, so as to clarify the respective rights and obligations of the producers, communicators, consumers and regulators of online literature and art, and clearly define all kinds of illegal acts and punishment measures in online literature and art practice, so as to provide sufficient jurisprudence and legal basis for online game supervision. At the same time, the regulatory authorities should work with online game research institutions to introduce online game quality grading standards as soon as possible to improve the online threshold of online games; Develop a workable mechanism for screening, inspecting and identifying mental damage in online games to provide technical support for supervision. In addition, it is necessary to establish an online game criticism team with experts and scholars as the main body, actively guide online game criticism public opinion, and implement all-weather and full-coverage academic monitoring of online game industry operation.

　　Deeply cultivate excellent cultural information resources on the Internet.

　　Online games should embark on the road of healthy and sustainable development. Apart from the macro-level management of the country, it is more important for online games to practice their internal skills, enrich their contents and enhance their cultural content.

　　Compared with traditional literary forms, online games have inherent advantages in the development and utilization of online cultural information resources because of their own Internet attributes, so they can make use of massive online cultural resources to achieve expanded reproduction based on high-quality IP and traffic factors. For example, the national treasure cultural relics collected in the Forbidden City can be carefully incubated as high-quality IP prototypes. When the traffic is cultivated to a certain amount and becomes an explosion "online celebrity", the first resource development from IP prototypes to online games can be realized according to the preset IP development roadmap. The online games developed for the first time, after gaining huge traffic, can be used as IP to expand the reproduction of TV dramas, variety shows and other products, and realize the re-dissemination from online to offline. By transforming the theme advantage of IP into the traffic advantage, and then transforming the traffic advantage into the content advantage, the social and economic benefits of online games can be maximized.

　　Online games are a cross-border literary form. In the future development, domestic online games should make use of the unique communication advantages of the Internet, break through the national barriers, capital barriers and technical barriers inherent in traditional literature and art, and realize the global communication of China’s story based on online games. Therefore, the online game industry in China must build a powerful online game communication platform with high efficiency, unique resources and convenient consumption by greatly increasing bandwidth, expanding giant servers, mobile online payment and other advanced technical means, and simultaneously make online games and their derivatives bearing specific China stories and China spirit into multilingual versions for all-weather and full coverage integrated marketing communication for netizens around the world.

　　Online game enterprises should clearly realize that the competition of online games in the future is cultural competition, and must abandon the commercial motivation of quick success and instant benefit and enhance the cultural content of products. Excellent Chinese traditional culture can provide rich materials for online game creation. In addition to adopting Chinese style in subject matter, pictures and music, we should organically embed the values of benevolence, loyalty and filial piety, benevolence, honesty, chivalry, humility and studiousness in Chinese traditional culture into game products. At any time, online games should correctly grasp the relationship between social benefits and market benefits, consciously put social benefits in the first place, do not be slaves to the market, and prevent economic interests from colliding with the bottom line of social morality.

The chaos in the water purifier market needs to be strictly controlled

Photo courtesy of China News Service

　　In recent two years, people have paid unprecedented attention to the health and safety of life and drinking water. With the popularization and improvement of health awareness, people’s drinking habits have gradually changed. From bottled water and bottled water to today’s water purifiers, we can see that the pursuit of healthy drinking water has become a fashionable trend, and it can also be said that the situation is gratifying.

　　At present, the overall situation of China’s water purifier industry is good. The whole water purifier industry presents a rapid development momentum, and the market prospect is brighter with the promotion of manufacturers. According to industry experts, the market capacity of domestic water purifiers will exceed 100 billion in five years. However, there is a saying that "there are three holidays in ten days", and the market is hot, which also exposes some problems.

　　The quality can’t pass repeatedly.

　　In recent years, the annual growth rate of water purifier market capacity in China has reached 50%. It is estimated that the market penetration rate of domestic water purifiers will reach 20% ~ 30% by 2019. However, behind the rapid growth of the water purifier market, many problems such as uneven brands, complicated installation and difficult maintenance have been hanging over the whole industry.

　　"The selling price of this one is only 100 yuan, but the other one sells nearly 5,000 yuan. The appearance looks similar, and it is really impossible to tell good from bad." Recently, after visiting the market, the reporter found that there are many brands of water purifiers and the prices are very different. Among them, the cheapest is only 196 yuan, which can be directly installed on the faucet. The most expensive one is the central intelligent water purifier, which costs nearly 10,000 yuan.

　　In order to attract customers to buy, merchants also put forward health concepts such as activity and rich oxygen ions, and publicity such as "beauty", "freckle" and "anti-cancer" are common. In a water purifier store, the clerk introduced a RO water purifier with a price of 4,998 yuan to the reporter, saying that "the filtration technology is the most advanced, which can remove 99% impurities and the water coming out is the healthiest". Seeing that the reporter suspected that the price was a bit high, the clerk introduced an ultra-filtration water purifier with a price of 998 yuan, and said that the filtered water is rich in minerals, which is beneficial to the body.

　　In addition to price confusion, the quality of water purifiers has been questioned. The General Administration of Quality Supervision, Inspection and Quarantine conducted spot checks on the water purifiers of 33 enterprises nationwide and found that 40% of them were unqualified. Lu Jianguo, director of the Health Appliance Analysis and Testing Center of China Household Electrical Appliances Research Institute, said that since 2014, the General Administration of Quality Supervision, Inspection and Quarantine has organized three national supervision and spot checks. The results show that the pass rate of water purifiers is less than 70%, which is a low level in the household electrical appliance industry.

　　An insider broke the news that a 2800-yuan RO water purifier was disassembled and found that the accessories were a meltblown filter from 1.8 yuan, a compressed activated carbon filter from 3 yuan, two granular activated carbon filters not exceeding 3.5 yuan, and a RO membrane from 60 yuan. "In addition to the low-end accessories, some businesses do not have ‘ Water batch ’ (Approval of Hygiene License for Drinking Water Hygiene and Safety Products) also dare to sell. "

　　The industry lacks supervision.

　　It is understood that there are more than 3,000 enterprises producing water purification equipment in China, and there are countless brands. However, the quality of water purifiers is uneven, and there are phenomena such as inflated prices and inaccurate reporting.

　　First, there are standards that are difficult to implement. At present, there are GB/T30307 national standards and QB/T4143 and QB/T4144 industry standards. The standards are available, but they have not been widely adopted. Most enterprises always try their best to bypass the standard requirements, and some enterprises do not implement the standard on the grounds of not knowing.

　　Second, there is supervision and it is difficult to cover. At present, the water purifier industry is in a state of many and scattered. Although there are more than 4,000 brands of water purifiers in China, only a handful of them can become national brands. Behind the prosperity of the industry, a large number of small enterprises driven by interests exist, which invisibly increases the difficulty of supervision and law enforcement.

　　Third, there is technology, which is difficult to distinguish. The biggest problem with water purifiers is poor experience, and it is difficult for consumers to distinguish between good and bad by appearance and price. Although there are water purification testing institutions, but the number is small, the price is expensive, enterprises are unwilling to test, so that some products do not meet the standard requirements are also listed for sale.

　　Fourth, consumers favor foreign brands, giving some unscrupulous businesses an opportunity to make huge profits under the banner of "foreign names". Lu Jianguo said that it is difficult to manage thousands of small workshop-style enterprises only by government-led supervision, and some enterprises have slipped through the net, resulting in exaggerated efficacy and false propaganda. He believes that consumer participation in market supervision is the best way to supervise.

　　Pay attention to safety in use

　　The main function of water purifier is to improve water quality and remove harmful substances such as residual chlorine, heavy metals and suspended solids, but using unqualified water purifier will pollute the water source. How to choose a qualified water purifier, Lu Jianguo gave several suggestions.

　　The first is to check the documents. It depends on whether the dealer’s sales documents (business license, organization code certificate, tax registration certificate, etc.) are complete. In addition, whether there is a health permit issued by the national health department for the health and safety of drinking water.

　　The second is to understand the water quality. In areas with good water quality, you can buy a filter water purifier; In heavily polluted areas with chlorine in water and heavy taste, or families with direct drinking needs, you can buy reverse osmosis water purifiers.

　　The third is to look at the filter. The high-hardness water quality in the north of China and the limestone area in the south of China have high calcium and magnesium ions, so you should buy an advanced filtration water purifier with ion exchange resin filter core. In areas with heavy chlorine and different colors and odors in water, you can choose a household water purifier with a large amount of activated carbon.

　　The fourth is to look at the wastewater rate. For similar water purifiers, try to choose the one with low wastewater rate. (Zhong Gong Net reporter Lu Xiang)

　　February 21st, the 28th day of aid to Hubei. It’s raining again in Wuhan.

　　When I went to work this morning, it was raining outside. I bought a loving little pholiota adiposa from the door of the hotel and hurried to work.

　　There are obviously more cars and even buses on the road around Jinyintan Hospital. There are also many people standing at the bus stop in the distance. Wuhan has not lifted the "closed city", so I guess they may be the medical staff in the living room (Fangcang Hospital) of Wuhan, and they have to take the shuttle bus back to their place of residence. You have worked hard, too.

　　When I changed my work clothes, I just arrived at the doctor’s office and saw a big plastic bag in front of Professor Zhou. When everyone was almost here, Professor Zhou opened the plastic bag, which contained several sets of protective clothing and swimming glasses. Professor Zhou said excitedly that this is a material sent to him by a Shanghai primary school student. Primary school students and their parents bought eight sets of protective clothing and donated them all. I hope everyone will be safe. I don’t know what kind of twists and turns this child and his family have gone through before they can collect protective clothing under the unified management of protective materials. From the childish handwriting of children, we can see the people’s care and love for us and the future of our motherland. The head nurse said that they also received materials from an aunt in Shanghai. The circle of friends said that the people of Shanghai "borrowed" us to Wuhan! The arrival of batches of materials expressed their care and they looked forward to our early and safe return. Everyone is very touched!

　　Next, it’s the shift handover time. After the shift handover, Team Zheng once again reiterated the safety issue, and let us carefully read the formula of wearing and removing protective clothing in Ruijin Hospital, so that each team member can remember four "musts": be highly vigilant, be strict in management, be sure to standardize the process and be cautious! Yes, we have been helping Hubei for 28 days, and now it is time to get tired and relaxed easily. We must cheer up and do a good job in protection and other work seriously and rigorously.

　　Today, I followed Professor Zhou into the isolation ward for rounds. After checking the room, the nurses have prepared a full set of tracheal intubation devices. After the patient was fully calm, Professor Zhou made a nasotracheal intubation under the guidance of bronchoscope. I admire his proficiency. Today, after working as an assistant and observing the actual operation, my heart is much more stable. As the saying goes, "more skills don’t weigh me down", and I learned new skills today. Professor Zhou completes tracheal intubation, adjusts the ventilator mode and parameters, and observes the patient’s vital signs for a while, which makes me feel more at ease.

　　Our group discharged a patient today. His symptoms improved, his nucleic acid test was negative continuously, and his lung CT examination turned better. According to the current process, patients need to be isolated at home for 2 weeks after discharge. However, the patient expressed the difficulty of his family’s housing shortage, and he was worried that it would affect other family members. We reported to the medical department of the hospital. Through coordination, when the patient leaves the hospital today, his community will send a car to pick him up and observe him in isolation at a nearby hotel for two weeks. I told him the two-week and four-week follow-up plan after discharge. Tomorrow and the day after tomorrow, there may be patients in our group discharged from the hospital. Spring has arrived in the intensive care unit.

　　In the afternoon, three columns of Chinese characters were posted in front of the first important door of our isolation ward. Maybe it will become a small scenic spot in Jinyintan Hospital in the future. Everyone lined up to take a photo with Professor Zhou, and I quickly lined up. Wuhan, come on! China, come on!

　　After work, the lights are already on outside. Because the team suggested that the medical staff should not eat directly in the canteen after work, fearing that it would be too late to eat after cleaning, I chose a self-heating hot pot and some fruits from the "energy station" and changed the dinner!
