　　Zhongxin. com, Hangzhou, November 3 rd (Shao Yanfei, Fu Feiyang) A history of Chinese ceramics, half of which is in Zhejiang; A history of Zhejiang ceramics, half in Longquan. The traditional firing technique of Longquan celadon began in the Three Kingdoms and the Jin Dynasty, flourished in the Song and Yuan Dynasties, and reached its peak in the Southern Song Dynasty. It is a "cultural symbol" juxtaposed with Song Ci and Song Painting, and is also the first ceramic project selected in UNESCO’s Representative List of Intangible Cultural Heritage of Humanity.

　　"Longquan celadon is well deserved ‘ Porcelain sea pearl ’ , exchange and learn from each other ‘ Cultural emissary ’ 。” Dan Jixiang, president of China Cultural Relics Society, commented on Longquan celadon.

　　Recently, the 5th World Celadon Conference (hereinafter referred to as Celadon Conference) was held in Hangzhou. The reporter interviewed many experts and scholars, celadon craftsmen and celadon culture lovers from home and abroad to explore the story behind Longquan Celadon — — Since it was passed down more than 1600 years ago, why is the Millennium kiln fire endless?

　　The watch relay of generations

　　People are the key factor in the inheritance of a skill.

　　Weisyun Lo, a master of arts and crafts in China and a celadon craftsman born in 1962, is now training more than 30 apprentices. In his view, it is necessary not only to teach porcelain art, but also to inherit ingenuity. "Let more young people have creative enthusiasm for porcelain art, so as to avoid the talent gap and truly realize the inheritance and development of Longquan celadon."

　　In fact, Weisyun Lo himself became famous. His teacher, Xu Chaoxing, has more than 500 skill inheritors, and has trained three China arts and crafts masters, including Weisyun Lo. The reporter from Zhongxin. com learned that the older generation of celadon craftsmen attach great importance to the inheritance of skills. It is precisely because of their generosity that Longquan celadon can be succeeded.

　　"In this exhibition, I brought two works, Prosperous Life and Peace. The former conveys an all-inclusive aesthetic feeling with a round and thick shape, and the flower-drawing technology of the flourishing peony symbolizes the prosperity of the motherland; The latter combines the local cinnabar porcelain clay in Longquan with the moist plum green glaze, reflecting the minimalist beauty of Song Yun culture. " At the "Song Porcelain Dreaming of China" held in conjunction with this celadon conference — — At the celadon immersive interactive art exhibition, Xu Xing, a celadon craftsman born in 1988, said.

　　Xu Xingxiao said that nowadays, the "post-waves" are endless, and he is no longer the youngest among his peers. A large number of "post-90 s" celadon craftsmen are participating in various competitions and exhibitions with excellent works.

　　"I met Longquan celadon and was attracted by its literati temperament at first sight." Liu Hao, a post-90s celadon craftsman, said that Longquan celadon is in line with China’s traditional culture. He hoped to use celadon culture as a carrier to open another window for visitors to understand the cultural and social features of the Song Dynasty and appreciate colorful Chinese culture, and also to use the platform of the World Celadon Congress to let people feel the beauty of celadon and the prosperity of Song Wenhua more intuitively.

　　Since the Song Dynasty, Longquan celadon has been exported to more than 50 countries in Asia, Africa and Europe. In the reporter’s opinion, celadon culture crosses mountains and seas and goes to the world from a small town located in southwest Zhejiang, which requires celadon craftsmen and young and energetic celadon culture communicators.

　　Wu Aizhu, a celadon enthusiast and self-media blogger who has settled in Hangzhou, is attending the World Celadon Congress for the fifth time. "The color of Longquan celadon is very beautiful, and the exhibition of this celadon conference has made me feel refreshed." Wu Aizhu said that Hangzhou has a profound cultural heritage. Promoting and spreading Longquan celadon here is expected to gather more information flow, technology flow, commodity flow and talent flow in a short time.

　　"In the training of Longquan celadon-related industries, we can build a traditional apprenticeship system, social human resources training, and ‘ Three-track system ’ Training mode. At the same time, we can introduce high-end talents and gather scientific research strength by relying on collaborative innovation platform, Industry-University-Research platform, enterprise research institute, local research institute and various research bases. " Zhou Xiaofeng, deputy director and professor of lishui university Scientific Research and Local Cooperation Department, said.

　　During the opening ceremony of this year’s celadon conference, many celadon craftsmen from 1980s and 1990s participated in the activity of "Celadon UP" and had a lively discussion on the inheritance and development of Longquan celadon. Among them, some young celadon craftsmen talked to the older generation of celadon artists, exchanged creative experience and talked about future development. The "baton" of celadon culture is quietly passed on in gossip … …

　　Password of Common Wealth in Porcelain

　　One side’s industry is rich, and the other side’s people. Celadon is to Longquan what shoes and boots are to Wenzhou and private enterprises are to Zhejiang. Thousands of years of inheritance, the kiln fire does not go out. Entering Baoxi Township, Longquan City, 13 Gulong kilns are shining under the local repair and protection.

　　In recent years, Longquan has devoted itself to decoding the genes of celadon culture, telling the stories of celadon culture, and relying on the well-preserved Gulong kiln in Baoxi Township in Ming and Qing Dynasties, it has launched the traditional dragon kiln firing activity of "never extinguishing the kiln fire", and integrated it into the special exhibition experience links such as blessing ceremony, blessing ceremony, saggar opening, online auction and dragon kiln banquet, and combined the inheritance of celadon culture with the innovative development of rural tourism.

　　It is understood that the "Guyaoli B&B" in Baoxi Township is the first Longyao Celadon Living Museum B&B.. Here, visitors can see the well-preserved ancient kiln, experience the whole process of firing celadon by the ancients and enjoy the pleasure of making porcelain.

　　According to the data, there are more than 60 farmhouses and homestays in Baoxi Township, and a number of fine homestays such as "returning from strangers", "Ancient Kiln", "Fengshutan Farmhouse" and "Bageshu Starry Tent Hotel" have been cultivated successively, effectively promoting the development of regional tourism.

　　Take Xitou Village, Baoxi Township as an example. In recent years, the village has continuously amplified the driving role of celadon culture, effectively extended the consumption time of tourists, guided rural sages and villagers to develop cultural tourism formats, expanded the night economy, and created a "white+black" tourism consumption model. It is understood that it has achieved an average annual tourism income of more than 30 million yuan, and many derived formats have enabled villagers to increase their income and get rich at their doorstep.

　　Jin Chaojun, a wanderer who has been wandering outside for many years and has been in the shopping mall for a long time, resolutely chose to return to Xitou Village for a second venture in the year of no doubt. He said that the increase in operating income is only a part of rural revitalization. More importantly, the IP of "Never Extinguish Kiln Fire" has improved the cultural consciousness and cultural self-confidence of all villagers.

　　According to statistics, by 2021, Longquan celadon has more than 20,000 employees, and there are more than 2,600 celadon manufacturers and workshops, including 5 enterprises above designated size; There are many masters and young talents in celadon industry, and the annual main business income is 1.714 billion yuan. Longquan celadon industry has become one of the local pillar industries and plays an important role in promoting common prosperity.

　　"Longquan celadon industrial structure still has room for further optimization and adjustment, which can be subdivided into various fields — — Create more celadon works featuring handcraft, small batch, quality and artistry; Seek breakthroughs in the fields of building ceramics, industrial ceramics, daily-use ceramics, bioceramics and special ceramics, and enhance added value … …” Zhou Xiaofeng said that Longquan celadon should also build a complete industrial chain consisting of raw material production, material research and development, equipment manufacturing, creative design, creative production, product packaging, online marketing and cultural communication.

　　Iterative upgrading of porcelain-making technology

　　From "looked up to" ritual vessels to "flying into ordinary people’s homes" daily necessities, Longquan celadon’s porcelain-making technology is also constantly upgrading.

　　Recently, many experts, scholars and industry professionals from home and abroad enthusiastically discussed the development of Longquan celadon technology in a series of forums, such as the theme forum of "Celadon Rejuvenation and Common Prosperity", and actively offered suggestions.

　　"Now the development of Longquan celadon industry is in line with the times, sharing the new achievements of scientific and technological development, and surpassing the ancients in raw material processing, molding methods and kiln firing." Zhou Shaohua, a professor at Zhejiang University and chief expert of Longquan celadon industry, said.

　　Zhou Shaohua said that from the dragon kiln to the coal kiln, to the liquefied gas kiln and then to the electric mixing, the kiln and firing technology represented by the "celadon high-temperature kiln controlled by electric mixing computer automation" are enough to envy the ancients; The application of digital machine tool finishing technology to porcelain is not only accurate in modeling, but also low in cost and large in output, which is a typical example of "stones from other mountains can attack jade"

　　As it says, Longquan celadon with a long history has not been lost in the long river of time, and the key lies in technology and innovation — — In 2020, Longquan celadon work "Clover Burned Porcelain Fragrance Insertion" traveled around space on the Long March 5 B carrier rocket; In July this year, Longquan celadon screen fan appeared in Hangzhou National Edition Pavilion, and more than 200 layers of celadon screen fans showed the Song Yun Fenghua &hellip that has been flowing for thousands of years; …

　　"We have successfully established an innovative service platform for Longquan celadon sword industry in Zhejiang Province, and introduced advanced equipment such as intelligent kiln, four-axis linkage carving machine and glazing machine to solve the problems of mechanization, intelligence and batch production." Hu Xianru, director of Lishui Economic and Information Technology Bureau, said.

　　Development is always accompanied by challenges. In the process of iterative upgrading of Longquan celadon technology, there are also problems that need to be solved urgently.

　　"In terms of scientific and technological innovation, Longquan celadon scientific research investment ‘ Be short of money ’ The utilization rate of porcelain glaze is low, and the standardized production capacity needs to be improved. It is necessary to increase investment in related fields and continuously promote technological innovation. " Zhou Xiaofeng said.

　　In Zhou Xiaofeng’s view, the technological innovation and artistic innovation of Longquan celadon should be inherited, transformed, integrated and innovated with cultural confidence without giving up the celadon cultural genes. "Under the condition of modern technology and diversified aesthetic development, it is inevitable to moderately carry out technological innovation and artistic innovation on traditional techniques, but it is necessary to maintain ‘ Degree ’ And ‘ Special ’ Under the premise of realizing the modern performance of traditional celadon techniques and the intangible bearing of modern cultural and creative products. "

　　At present, the digital reform has also brought profound changes to Longquan celadon.

　　As one of the highlights of this celadon conference, "Song porcelain dreams of China" — — The immersive interactive art exhibition of celadon attracted many participants to stop and watch. Two large digital screens in the exhibition area reproduced the past lives of Longquan celadon from four sections: Life, Rite and Music, China and World.

　　"At present, we are focusing on building ‘ Longquan celadon non-legacy industry online ’ Digital application, build an online platform for celadon exhibition, build a celadon non-legacy resource library, classify, stereo record, graphic, audio and video, VR exhibition and other all-media materials into a unified database, and provide a good display and development platform for celadon craftsmen and their works. " The relevant person in charge of Longquan City said. (End)

　　Cctv newsA MV-22 Osprey transport plane of the US military crashed into the sea in the waters near Australia, and 23 people were rescued. Three people were declared dead after missing. In Okinawa, where the "Osprey" often flies overhead in Japan, this news has increased the anxiety and opposition of the local people.

Okinawa local people marched.

　　On the 8th, Esaki Tetsuma, Japan’s new Minister for Okinawa and Northern Territory Affairs, said in a rare way that the Japan-US Status Agreement, which stipulated the legal status of US troops stationed in Japan, "must be slightly revised".

　　At the press conference, Jiang Qi stressed, "Even if it takes more time, the government should fully understand the feelings of Okinawa residents. What it should say to the United States should be said."

　　However, as for the Japan-US Status Agreement, he said that "I am a layman" and did not talk about the specific direction of revision.

　　Japan and the United States signed the "Japan-US Status Agreement" in 1960, which stipulated that when civilian and military personnel employed in the US military base in Japan caused accidents or committed crimes while performing official duties, the US military stationed in Japan enjoyed priority jurisdiction, which was essentially equivalent to giving this group judicial immunity.

　　Whenever US military personnel commit crimes in Okinawa or an accident occurs in US military aircraft, the Japanese people’s call for amending the Japan-US Status Agreement is even louder.

　　However, under the pressure of the United States, the Japanese government has been holding a negative attitude towards amending the Japan-US Status Agreement for many years.

　　As the newly appointed Minister of Okinawa Affairs in the cabinet reshuffle on the 3rd of this month, Jiang Qi offered to amend the Japan-US Status Agreement, which was even called "rare" by the Japanese media. However, it is not clear whether Jiang Qi’s statement reflects the overall policy of Abe’s government.

　　However, an Osprey still took off and landed from the Futenma base in Okinawa on the 7th — — The Japanese media believe that the US military has demonstrated the de facto "refusal posture".

　　On the 8th, Nicholson, the highest commander of the US military stationed in Okinawa, even told Tomokawa Shengwu, the deputy governor of Okinawa Prefecture, who came to protest, "‘ Osprey ’ Flying around the world is the policy of the US military, which explicitly rejected the Japanese request for grounding.

How is your pure electric car experience in the cold winter?

The discount on battery life may not be the worst thing. Recently, more than a dozen Tesla owners in Canada have reported that even the air conditioner can’t be used in winter. Not only is the car frozen at a discount, but people are also frozen with a snot and tears.

Moreover, the basic things that can’t be heated in winter are heat pump air conditioners.

This is very strange. The high-efficiency and energy-saving advantages of heat pump air conditioners have not been brought into play, but they cannot be heated, which has attracted the doubts of some Canadian car owners and attracted the attention of Tesla’s R&D team. Musk said that this is a high priority for Tesla.

But even weirder, Musk said that the failure of heat pump air conditioner turned out to be a software problem, which can be completed by firmware update. Perhaps many people have never heard of it, and air conditioners still need OTA. However, after understanding the structure and working principle of Tesla heat pump air conditioner, we can find that this set of hardware can realize 12 different functions, and all the functions are controlled by software.

Therefore, the problem of Tesla heat pump air conditioning may really be a software problem.

So, how amazing is Tesla’s heat pump air conditioner? Why can’t refrigeration occur under extremely cold conditions? Can the industry solve this problem? After reading the patent of Tesla heat pump air conditioner and having a conversation with the Weiling engineer of Midea, the car found the answer to the question.

This month, countries in the northern hemisphere ushered in the coldest time since winter, and electric vehicles also entered the worst stage of the year.

Recently, Tesla owners in Canada reported that they were driving in an extremely cold environment and the heat pump air conditioner could not be used.

Twitter user @TSelvig said that when traveling that day, the temperature had dropped to-40 C. In this extremely cold weather, when he was driving Tesla Model Y, the heat pump air conditioner could not be used. After trying to restart the vehicle and call Tesla customer service, this problem still cannot be solved, and the owner is a few hours’ drive from the nearest service center, so it is impossible to drive without air conditioning.

In the end, the family switched to a fuel car.

Another Model Y owner @paateach has a richer experience. His Model Y has no warm air for two consecutive winters.

He tweeted that he lived in Saskatchewan, southern Canada, and in February last year, he encountered the situation that the heat pump air conditioner could not be used, and there was no warm air for a whole month. Later, Tesla replaced a group of super manifolds for him, and the heat pump air conditioner could be used at that time. However, by this winter, when the temperature dropped to -30℃, he once again encountered the situation that the heat pump air conditioner could not be used.

At that time, he photographed the prompt on the car screen: the cockpit climate control system needs maintenance, and the heating and cooling systems will be restricted or unusable.

Two car owners questioned Tesla: Why did Tesla’s heat pump air conditioner fail in extremely cold weather? Tesla has been repaired several times, why is the maintenance plan still invalid?

Some car owners even said that after this winter, they hope to sell their Tesla in exchange for a fuel car, at least there will be no air conditioning and heating failure.

Angie Dean, chairman of Tesla Owner’s Club in Alberta, Canada, said: "In Alberta and Saskatchewan, Canada, more than a dozen Tesla owners have experienced the problem that heat pump air conditioners cannot be used."

Just last week, the owner community Drive Tesla Canada tweeted @ Musk, asking him to comment on the heat pump problem. Musk replied to the tweet within 5 minutes, saying that maintaining the heat pump air conditioner has a very high priority. After 40 minutes, Musk said that the new firmware of heat pump air conditioner has been introduced to users.

It is quite curious that why the failure of heat pump air conditioner can be repaired by firmware update? In addition, after the firmware update is completed, there is still feedback from the owner that heating cannot be done. Is the firmware update useful?

In a patent document published by Tesla in 2019, the structure and operation mode of the heat pump air conditioning system were demonstrated. At the beginning of 2020, with the mass production of Model Y, this patent was also transformed into the mass production application of Tesla.

If you open the front case of Tesla, you can see the heat pump air conditioner and many pipes and harnesses. In fact, this is just the tip of the iceberg of the heat pump system. From the patent drawing, Tesla’s heat pump air conditioner has 11 main components, and is responsible for the thermal cycle of the whole vehicle, which can lead to different parts of the vehicle such as cockpit, battery pack and motor.

These main components are compressor, cabin condenser, cabin evaporator, battery system cooling device, cabin blower, motor liquid-cooled condenser, storage battery, three-way compressor air outlet, low-voltage electric cabin heater (PTC), recirculating air conditioner and heating.

Among the 11 main components, Tesla did not directly cancel the traditional PTC heating, but still equipped with a low-voltage PTC heating. However, due to the lack of power, this PTC heating device can not directly heat the cabin, but provides auxiliary heating when the heat pump system is insufficient.

Surprisingly, Tesla’s hardware can realize 12 different working modes, which are completed by different software scheduling.

Among these 12 working modes, there are only three modes in which heat pump participates. Heat pump participation in heating can be divided into pure heat pump mode and mixed heating mode. When the heat pump efficiency is high, the pure heat pump mode is activated, and when the efficiency is low, the mixed heating mode is activated. The heat pump can be mixed with PTC heating and can also be added to the evaporator for heating together.

In addition, the cabin and battery system can be heated simply by using the compressor and evaporator. In addition, the in-vehicle thermal circulation system can also realize the functions of cabin defogging, defrosting, dehumidification and so on.

A conclusion can be drawn here: it is indeed feasible to fix the problem of heat pump air conditioning through firmware update.

When there is nothing wrong with the hardware of the heat pump air conditioning system, the adjustment of the heat pump air conditioning system can be realized by adjusting the software scheduling in different environments.

As far as the heat pump system is concerned, there is a strong relationship between the efficiency of heating the cabin and the efficiency of the heat pump. Because the working principle of heat pump air conditioning is to exchange heat energy inside and outside the car.

Through the evaporator, the refrigerant can absorb heat from the external environment, and after the refrigerant in the car is liquefied, it releases heat, so that it can heat the cabin.

However, if the temperature of the external environment is lower, it is more difficult for the refrigerant to obtain heat from the external environment, which leads to the low heating efficiency of heat pump air conditioning in extremely cold environment.

Tesla also knows this obvious problem, so it adds auxiliary heating devices in addition to heat pump air conditioning.

Tesla drew a chart in the patent, which can explain the efficiency of heat pump air conditioning at different temperatures. The efficiency coefficient of heat pump air conditioning is expressed by COP(Coefficient of Performance). When COP=1, it means that the consumed electric energy is equal to the generated heat energy. When COP>1, the heat pump air conditioner is in the high efficiency area, which means that it can get more heat energy by consuming less electric energy.

As can be seen from Tesla’s chart, when the ambient temperature and battery temperature are lower than -20℃ at the same time, the efficiency of heat pump air conditioning will be very low, which is also considered as extremely cold temperature by Tesla, and there is no solution below this temperature. But at this time, just heat the battery, the COP value will increase, and the heating system can be used normally.

When COP=1, the heat pump air conditioner does not work and relies on evaporation to achieve heating. When COP≥1, the heat pump air conditioner will participate in heating, and the temperature needs to be above -10℃.

The second conclusion can be drawn here: if the weather outside is extremely cold, even if the firmware of the heat pump air conditioner is updated, the heating effect will still be poor. The solution is to heat the battery, or preheat it before going out.

However, under the tweet that Musk replied to the updated firmware, there are still many users who feedback that the vehicle still cannot heat.

Then, there is probably a hardware problem.

Tesla owner @paateach said on Twitter that his Tesla Model Y has been replaced with two super manifolds, including the sensor of heat pump air conditioner, expansion valve and refrigerant pipeline. The heating system can be used temporarily, but I am very worried that it may be damaged again.

Twitter user Tesla owner revealed the research and development story of heat pump air conditioner online. Recently, Tesla’s engineers in California and Alaska are testing heat pump air conditioners. The test results show that Tesla’s heat pump air conditioners can work normally below -30℃ because the heat pump air conditioners have two refrigerant cycles.

At the same time, engineers also found the problem: in extremely cold weather, the cover plate of the front air inlet will be frozen and damaged, which will lead to the inhalation of cold air during driving. Because the cold air temperature is too low, the sensor will report an error to the system after sensing it. At this time, the compressor will stop working and the heating will stop.

In order to solve this problem quickly, Tesla may start the compressor by software, temporarily avoiding the heating failure in extremely cold weather. But to solve this problem completely, Tesla may need to update some hardware later.

For the automotive industry, heat pump air conditioning is still a new thing, and Tesla Model Y was mass-produced in early 2020. Prior to this, pure electric vehicles generally used PTC to heat the interior of the car. But even under ideal conditions, the COP of PTC is 1. Low efficiency leads to very large electricity consumption for PTC heating, which further becomes a major factor affecting the battery life of electric vehicles in winter.

The efficient performance of heat pump air conditioning has attracted the attention of electric vehicle companies. In 2021, all new pure electric vehicles were basically upgraded from PTC heating to heat pump air conditioning. However, due to the limitation of refrigerant, when the temperature is below -10℃, the efficiency of heat pump will be greatly reduced. At this time, it is necessary to rely on PTC heating to heat vehicles.

For example, Tucki P5 is equipped with a heat pump air conditioner to achieve efficient heating, but it is also equipped with PTC. When the temperature is lower than -10℃, the vehicle will start PTC heating to heat the interior.

It can be said that Tucki P5 has solved the shortcomings of heat pump air conditioning to some extent, but it has not been completely solved.

Weiling, another new auto parts manufacturer, has solved the heating problem in extremely cold weather. Speaking of Weiling, maybe many friends in the automobile circle are no strangers. Weiling is a subsidiary of Midea Group, a domestic appliance head enterprise.

Last year, several auto parts announced by Weiling included automotive heat pump air conditioners.

At present, R134a(CH2FCF3, tetrafluoroethane) is usually used as the refrigerant for heat pump air conditioning, but when the outside temperature is low, the heating capacity is obviously attenuated. Therefore, there are explorations of mixed refrigerants in the industry, but the performance cannot be significantly improved.

The engineers of Weiling parts found another way, using carbon dioxide as refrigerant, and the heating efficiency was obviously improved at extremely cold temperatures.

Weiling’s rotary CO2 electric compressor can achieve a heating efficiency of COP=2 at -30℃. At the same time, the noise is low during operation and the overall design is lighter.

Engineer Weiling introduced that in extremely cold weather, users don’t need to "cover the quilt" to drive. At the same time, compared with traditional heat pump air conditioners, the heat pump with carbon dioxide as refrigerant can increase the cruising range of vehicles by up to 20%.

The CO2 electric compressor alone has 220 domestic invention patents and 14 international invention patents, and has completely independent intellectual property rights. At the same time, CO2, as a common greenhouse gas, is collected and used as a refrigerant, which also contributes to "carbon neutrality".

Last year, the heat pump air conditioning products of Midea Group Weiling components have been installed on pure electric brand vehicles such as Tucki and Weilai, which has become a microcosm of the rapid transformation of domestic component enterprises to electrification.

In 2020, Tesla put the heat pump air conditioner into a pure electric vehicle, which led the electric vehicle industry to take another step towards high efficiency. In just one year, by 2021, heat pump air conditioning has become the standard of high-end electric vehicles.

Obviously, the technology that will not be used in the era of fuel vehicles may be a huge innovation in the era of electric vehicles. In today’s increasingly fierce global competition for electric vehicles, there is still huge room for innovation in the field of electric vehicles.

　　Writing the answer sheet of the times to reform and strengthen the army

　　— — Summary of achievements in national defense and army building in the new era (II)

　　■ Liberation Army Daily reporter Qian Xiaohu Han Cheng

　　In the desert Gobi, a certain unit of the army organizes multi-arms cross-domain maneuver and three-dimensional attack and defense; Over the East China Sea, the J -20 fighter formation thundered forward to carry out actual combat drills in the maritime direction; In the western Pacific, the carrier formation of Liaoning ships is breaking waves and tempering its offshore combat capability … … On the occasion of the people’s army’s 95th birthday, we can truly feel the profound changes brought by the reform and strengthening of the army through the turbulent pictures on the training ground of the three military exercises.

　　A strong country must strengthen the army, and a strong army must reform. In November, 2015, when the snow began to fall in Beijing, the Central Military Commission’s reform work conference was held. President Xi issued a mobilization order to deepen the reform of national defense and the army: fully implement the strategy of strengthening the army through reform and unswervingly follow the road of strengthening the army with China characteristics. The unprecedented integrity and revolutionary changes in the strength, depth and breadth of our military history have thus begun.

　　The spring tide is surging, and the torrent is brave. The organizational structure of our army has undergone a historic transformation, the road to elite soldiers with China characteristics has taken a historic step, and Socialism with Chinese characteristics’s military policy system is becoming more and more complete … … Today, the people’s army reborn from the fire is accelerating towards the goal of a world-class army by leaps and bounds.

　　Strategic plan, "key trick" to win the future

　　It is often a keen and powerful ideological lever that incites history.

　　Standing at the new time coordinate point, looking back at the course of national defense and military reform again, and looking back at the holistic and revolutionary reconstruction and remodeling brought by this round of reform to the people’s army, we feel more deeply the profound historical vision, broad strategic considerations and strong mission responsibility of the military commander.

　　Back to November 15th, 2012, just after the 18th National Congress of the Communist Party of China closed, President Xi presided over the first executive meeting of the new Military Commission, which clearly pointed out that we should always forge ahead in the spirit of reform and innovation and strive to seize the initiative in military competition. More than 20 days later, President Xi came to the forefront of China’s reform and opening up — — Guangdong, inspected the Haikou ship at Shekou Port in Shenzhen and sailed with the ship for 4 hours.

　　"President Xi has high hopes for reforming the strong army and building a strong navy." After a lapse of 10 years, when President Xi inspected the scene overlooking the sea, Shan Donghui, the captain of Haikou Ship, was still vivid; The earnest entrustment of the commander-in-chief always haunts the hearts of naval officers and soldiers. Now, the photo of President Xi and the sailors at the bow of the ship is displayed in the Military History Museum of the detachment where Haikou Ship is located, always encouraging officers and men to be strong in the chart.

　　If you can’t make the sea, you must make it. The Sino-Japanese War of 1894-1895, more than 100 years ago, was a very painful "national mourning" in the history of modern China, and was called "the pain of gouging out one’s heart" by President Xi.

　　Gaze at history and observe reality. In the second decade of 21st century, China has become the second largest economy in the world. However, the road from the big to the strong is doomed to be uneven.

　　Looking around the world, the international pattern and system are undergoing profound adjustment, the global governance system is undergoing profound changes, and the international power balance is undergoing the most revolutionary changes in modern times. In this unprecedented great change, the new military revolution in the world, with the essence of fighting for the strategic initiative, has developed in depth, and major countries have adjusted their security strategies and military strategies one after another, and adjusted their military organizational forms. Its speed, scope, depth and influence are rare since the end of the Second World War.

　　"Once the military backwardness is formed, the impact on national security will be fatal. I often read some historical materials of modern China, and it hurts me to see the tragic scene of being beaten behind! " President Xi warned the whole army that the new military revolution provided us with a golden opportunity. We must hit the water in the middle stream, and we can’t do it without changing it, and we can’t do it if we change it slowly. This is a big exam that we can’t avoid. The army must hand over a qualified answer to the party and the people and to history.

　　A hundred battles struggle, and those who struggle first. Focusing on the multiple considerations of history and reality, international and domestic, war and peace, a blueprint for profound changes in the future of the people’s army has been brewing in the commander’s mind.

　　"What I think most is whether our army can always uphold the absolute leadership of the party when the party and the people need it, whether it can pull up and win the battle, and whether commanders at all levels can lead troops to fight and direct the war." At an important meeting of the army, President Xi’s words struck a deaf ear. This is the questioning of the times and the questioning of the mission.

　　Examination and questioning come from a deep insight into the risk challenges on the road ahead, and more from a clear understanding of our military’s capabilities and shortcomings — — "There is still a big gap between the modernization level of our army and the national security demand, and between our army and the world’s advanced military level", "Our army is not capable of fighting modern wars, and cadres at all levels are not capable of commanding modern wars", "Without reform, we can’t fight and win battles" … …

　　National rejuvenation, read here; Strengthen the army and build the army, and linger at night. President Xi profoundly pointed out: We must deepen the reform of national defense and the army with greater wisdom and courage. This is the requirement of the times to realize the Chinese dream and the dream of strengthening the army, the only way to strengthen the army and the key measure to determine the future of the army.

　　Seek the layout of the article, and make a sound. On March 15, 2014, a message from Xinhua News Agency attracted much attention at home and abroad: the supreme leader served as the leader of the Central Military Commission’s leading group for deepening national defense and army reform. It is the first time in the history of the party that the general secretary of the party personally serves as the leader of the leading group for deepening the reform of national defense and the army.

　　This year marks the 120th anniversary of the Sino-Japanese Sino-Japanese War of 1894-1895. After two Jiazi, China’s army embarked on a brand-new starting point of transformation and strength.

　　"The easy and happy reform has been completed, all the delicious meat has been eaten, and the rest are hard bones." Facing the tough battle of national defense and army reform, President Xi encouraged all officers and men of the army: The more difficult it is, the more determined they must be and forge ahead, and they must never be hesitant and timid. As long as the whole army unites its will, dares to gnaw hard bones, and dares to wade in dangerous beaches, there will be no flaming mountain that can’t be crossed!

　　At the critical moment, the strategic vision and political determination of the supreme commander are the decisive factors for the success of the reform. Focusing on promoting the reform of national defense and the army, President Xi presided over the collective study of the Political Bureau of the Central Committee twice, presided over the meeting of the leading group for the reform of the Military Commission three times, listened to the opinions and suggestions on the reform of large units many times in person, and personally organized and studied major issues of reform.

　　Where are the institutional obstacles? What are the structural contradictions? How many policy issues are there? A number of reform special groups and expert advisory groups conducted extensive research, concentrated wisdom and repeatedly demonstrated — —

　　More than 690 military units, more than 800 symposiums and demonstration meetings, more than 900 on-the-job and retired military leaders and experts, more than 2,000 team members of units above the military level and officers of divisions and brigades, and more than 3,400 opinions of officers and men of the army. The reform plan has been adjusted, revised and improved more than 150 times before and after … …

　　The reform of national defense and the army concerns the overall situation and the whole country. From inside the military to outside the military, from the central government to the local government, all localities and departments have given strong support to deepening the investigation and demonstration of national defense and military reform and drawing up plans, thus forming a touching situation in which the party, government, army and people in Qi Xin work together to help reform. The National Development and Reform Commission, the Ministry of Industry and Information Technology and the Bureau of Science, Technology and Industry for National Defense actively participated in the reform demonstration; The Central Organization Department, the Ministry of Civil Affairs and Ministry of Human Resources and Social Security launched an in-depth study on the reform of management and security for retired military personnel & HELIP; …

　　Fighting day and night, the Military Commission Reform Office launched a high-intensity, high-density and wide-ranging investigation. Opinions and suggestions from all sides, like a clear spring, inject fresh vitality into the scheme.

　　In July 2015, President Xi presided over the third plenary meeting of the leading group for the reform of the Central Military Commission, and reviewed and approved in principle the Proposal on the Overall Plan for Deepening the Reform of National Defense and the Army. Subsequently, President Xi presided over the executive meeting of the Central Military Commission and the The Politburo Standing Committee (PSC) meeting respectively to review and approve the Overall Plan. A set of reform designs that solve deep-seated contradictions, have major innovation breakthroughs, and reflect the characteristics of the people’s army have emerged.

　　The hoof is fast and steady, and the "three major battles" are like a rainbow.

　　Some moments are destined to be unforgettable, and some events are destined to go down in history.

　　In the snowy midsummer, the sky is high and the clouds are light, and the harsh alarm cuts through the tranquility of a brigade camp of the 76 th Army. Personnel gathering, unpacking equipment and loading formation … … A full-loaded pull drill kicked off. Looking at the new barracks which integrates the functions of command, training, living and security, Qiu Shaoyun’s company commander Dunzhi Bading really felt the strength of reform: five years ago, when the company moved thousands of miles from Hexi Corridor, it was still a desolate Gobi.

　　Reform affects the hearts of every officer and soldier. "What is discipline, that is, the party will do whatever it wants." As a witness and witness, Dun Chi-Badin knows well the difficulty of relocation and the pain of reform. "But no matter how difficult and painful it is, we must be resolute and resolute."

　　This is a historic moment: at 0: 00 on January 16, 2016, the seven military regions of Shenyang, Beijing, Lanzhou, Jinan, Nanjing, Guangzhou and Chengdu stopped exercising their command, and the five war zones in the east, south, west, north and central began to operate.

　　In less than a month, 15 functional departments of the Central Military Commission were adjusted and formed, and the army leadership, rocket army and strategic support forces were established, which made a big step in the reform of the leadership and command system.

　　Focusing on implementing the requirements of political army building under the new situation, promoting the organic unity of leading and commanding troops and deepening the reform of national defense and the army, the "first battle" starts with breaking the headquarters system, the military region system and the continental army system, and the first move is to build a leadership and command system of "the Central Military Commission is in charge of the general, the main battle of the theater and the main construction of the service".

　　With one order, the headquarters system that has been running for decades has become history overnight. Among them, the number of institutions above the division level has been reduced by more than 200, and the number of personnel has been reduced by one third. Military Commission — War zone — The operational command system of the army and the Central Military Commission — Services — The leadership and management system of the army started to operate, and the long-standing institutional obstacles of the army were effectively solved.

　　According to experts’ evaluation, the new pattern is of great significance for ensuring the party’s absolute leadership over the army, ensuring the efficient command of the army by the military commission, ensuring the scientific planning of the military commission and strengthening the management of army building.

　　The first battle laid the foundation stone and took advantage of the situation. In December 2016, a conference on the reform of the military scale structure and strength of the Central Military Commission was held in Beijing. President Xi personally deployed and deepened the "second big battle" of national defense and army reform.

　　The reform of scale structure and strength organization is not simply "addition and subtraction", but the optimization of structure and function leads to scale adjustment, focusing on cracking structural contradictions and realizing the revolutionary reshaping of our military strength system, which is "slimming" and "strengthening the body". Throughout the history of world military development, the scale structure and strength of the army cannot be fixed, but must change with the changes of war forms and combat methods, as well as with the changes of national strategic needs and military missions and tasks. Otherwise, no matter how powerful the army is, it will be out of date and even vulnerable.

　　On April 18th, 2017, President Xi met with the heads of 84 corps units newly reorganized by the whole army. Ten days later, the regular press conference of the Ministry of National Defense revealed that the army’s 18 group army titles were revoked, and the 13 group army titles after adjustment and formation were announced at the same time. In that reform, Qiu Shaoyun’s former army, like many troops deployed for relocation, left the old camp that had been stationed for more than 40 years, came to a strange new station, and came to a place closer to the front line of military struggle, set up camp, and prepared for training and consolidation.

　　The boldness and boldness of China’s military reform once again shocked the world: the number of military posts was reduced by 300,000, and the total number of active posts was reduced to 2 million; More than 1,000 units and institutions above the corps level have been reduced, the number of active posts in non-combat institutions has been reduced by nearly half, and the number of combat troops has increased rather than decreased, making it more substantial; The thinking pattern and historical inertia of the concept of mechanized warfare in the "Great Military Region" and "Continental Army" have been gradually changed. The mode of focusing on military groups and winning by quantity, the power structure and deployment of land-based and homeland-defensive forces have been changed, and the degree of integration of troops, the flexibility of operational grouping and application have been significantly improved.

　　If the reform of the leadership and command system focuses on "strengthening the brain", the reform of scale structure and strength formation focuses on "strengthening the bones and muscles", and the reform of the military policy system focuses on "connecting the meridians". In mid-November 2018, the Central Military Commission’s policy system reform work conference was held in Beijing, which opened the prelude to deepening the "third big battle" of national defense and military reform.

　　"The military policy system regulates military relations, standardizes military practice, and ensures military development. The reform of the military policy system is very important for realizing the party’s goal of strengthening the army in the new era, building the people’s army into a world-class army in an all-round way, and realizing ‘ Two hundred years ’ The Chinese dream of striving for the goal and realizing the great rejuvenation of the Chinese nation is of great significance. " President Xi’s important speech pointed out the direction for promoting reform.

　　Four days after the meeting, the list of policies and systems issued just before was released. Twenty-seven policies and systems were included in the list, including strengthening the construction of party organizations, selecting and transferring cadres in war zones, improving the relevant policies of troops stationed in plateau islands, encouraging scientific and technological innovation, managing employment contracts for civilian personnel, and providing medical care for military personnel and their families.

　　Promote the reform of military expenditure management, military salaries, housing and medical security, improve the management and security system and mechanism of retired military personnel, and build and improve the military honor system … … A series of policies and systems embodying the characteristics of military occupation have been stepped up, providing a solid institutional guarantee for improving the combat effectiveness and stimulating the vitality of the troops.

　　Rebuild and rebuild, and the "big country array" has taken on a new look.

　　Time is the best developer and the best touchstone.

　　At the foot of Helan Mountain, the wind and thunder surge. The "Western Joint -2021" exercise, which attracted worldwide attention and was full of bright spots, was launched at the Army Qingtongxia Contract Tactical Training Base.

　　In this exercise, China and Russia sent more than 10,000 troops, invested in multi-type aircraft, artillery and armored equipment, and conducted dozens of exercises such as joint air defense, joint obstacle breaking and joint three-dimensional capture. The armed forces of the two countries reached a new height in coordinated operations.

　　The exercise was led by our army, instead of the independent grouping planning before, it was changed into the mixed grouping and joint planning of the two armies, and the bilingual command information system was used throughout, and the situation data was shared … …

　　Seeing many new changes, the military experts on the spot can’t help feeling the performance of China’s army: the command level of this exercise is flatter, the operational grouping is more flexible, and the degree of integration and modularization is higher. It can be seen that a joint combat force system with elite combat forces as the main body is taking shape, which vividly shows the new achievements and new leaps of China’s military reform.

　　Looking back at the Gobi smoke, focusing on the future battlefield. In just a few years, the People’s Army has accelerated its changes in the "new system time": the army’s mobile operations and three-dimensional offensive and defensive capabilities have been significantly enhanced, the navy has accelerated the transformation from offshore defense to offshore defense, the air force has accelerated the transformation to air and space integration, and both offensive and defensive capabilities have been enhanced. The Rocket Army has continuously strengthened its nuclear and conventional capabilities, and the strategic support forces have made every effort to promote the leap-forward development of key areas & HELIP; … With a new system, a new structure, a new pattern and a new look, a new combat force with a leaner scale, a more optimized structure and a more scientific organization is accelerating its rise.

　　— — The command system is lean and efficient. Military Commission — War zone — The operational command system of the army started to operate, and the highest leadership and command of the army were concentrated in the CPC Central Committee and the Central Military Commission. Compared with the original four headquarters, the new Military Commission has a clearer path of command, construction, management and supervision, a more rational allocation of functions of decision-making, planning, implementation and evaluation, and a more focused strategic planning and macro management, and has truly become a staff organ, an executive organ and a service organ of the Military Commission. The focus of joint operational command is on the war zone, and the focus of army construction management is on the arms and services. The war zone specializes in fighting and is mainly engaged in joint operations, and the services take fighting to lead and seize construction as the battle. Implement the military in the main combat troops of the whole army — Brigade — The battalion system, the combat forces of various arms have been strengthened, the command level has been reduced, the operational command has become flatter and smoother, and the combat formation has become more comprehensive and flexible.

　　— — The scale structure is constantly optimized. An exercise of crossing the sea and landing on the island started in the summer storm, and the Marines dressed in starry camouflage uniforms made a new appearance. In this round of reform, the Marine Corps, Air Force Airborne Forces, Rocket Forces, Strategic Support Forces, Joint Logistics Support Forces and many other new combat forces were newly adjusted and formed, and the active posts of the Navy and Rocket Forces were moderately increased. For the first time, the posts of the Army were reduced to less than 50% of the total posts of the whole army, and the proportion of services and arms and the proportion of officers and men were greatly improved; The establishment of organs at all levels has been reduced, the internal organs, leadership levels and personnel of organs at all levels have been reduced, and the staff of organs at or above the regimental level have been reduced by about a quarter; Elite combat forces such as aircraft carriers, large destroyers, strategic early warning aircraft, air assault and special operations have been strengthened, which has effectively promoted the transformation of the people’s army from quantitative scale to quality and efficiency.

　　— — Joint war and joint training start a new game. The roar of air fighters, the array of ground missiles, and the galloping of warships at sea … … In early May, the Eastern Theater organized naval, air and naval forces to conduct normalized live-fire drills in a certain sea and airspace. After the reform and adjustment, the whole army’s concept of preparing for war and joint training has been further strengthened: the Central Military Commission has made great efforts to solve practical problems such as the theory and regulations of theater construction, and established a theater joint operation command system with "four beams and eight pillars"; Each theater plays the role of joint warfare and joint training hub, pulling joint training with realistic tasks, leading joint training with operational plans, inciting joint training with inspection and evaluation, and truly realizing joint training to lead and support joint training of arms and services; All services and arms closely meet the needs of joint combat capability in the theater, innovatively organize a series of service and arms campaign training, and jointly train with the service and arms capability training support system to continuously improve the contribution rate of winning the war.

　　— — The policy system has become more perfect. On January 1, 2021, the "Provisional Regulations on the Administration of Officers in Active Service" and related supporting regulations were implemented; On March 31, 2022, the Provisional Regulations on Non-commissioned Officers, the Provisional Regulations on Conscripts and related supporting regulations were implemented … … Officers and men have called for reform, and a large number of laws and regulations that are in urgent need of reform and preparation for emergency have been formulated, promulgated or revised. Establish the professionalization system of military officers, optimize the treatment guarantee for military personnel, improve the policy system of military training, equipment development, logistics construction, military scientific research, national defense mobilization, etc. The system of military laws and regulations with China characteristics has been continuously improved, so that all factors conducive to the construction of combat effectiveness can compete with generate’s vitality, attract and gather outstanding talents to the maximum extent, and effectively stimulate the enthusiasm, initiative and creativity of officers and men in reforming and strengthening the army.

　　China’s military reform has attracted worldwide attention. At the School of International Defence of National Defense University, middle and senior officers from multinational armies once held a round-table discussion entitled "Military Reform in China". A foreign military student said with emotion, "The military reform in China involves a wide range of issues, and it is a huge and complicated project. The smooth progress of the reform fully reflects the Communist Party of China (CPC)’s strong leadership. "

　　Standing at the new historical tide and looking back at the magnificent picture of reforming and strengthening the army, we firmly believe that under the strong leadership of the CPC Central Committee with the supreme leader as the core, the people’s army in the middle stream will always maintain its determination to reform and the courage to overcome difficulties and create "new and greater miracles that will impress the world"!

　　In the eyes of the public, "top three hospitals" are the golden signboard of hospitals. Similarly, many hospitals also need to obtain the "international version" of high-level medical standard certification for the needs of conducting business exchanges with overseas hospitals and accepting international commercial insurance payments.

　　This year, Shenzhen took the lead in breaking through. On September 22nd, the Shenzhen Municipal Government held a press conference on "International Certification Standard for Hospital Quality (2021 Edition)" (referred to as "International Standard (2021 Edition)"), and officially released the "International Edition" hospital accreditation standard. This is also the first internationally certified hospital accreditation standard in China, which will strongly promote the internationalization of hospital accreditation standards in China.

　　International insurance customers can "brush medical insurance" in China.

　　With the increasingly frequent international exchanges, more and more China residents or foreigners need to use the international commercial insurance they have purchased for medical treatment in the Mainland, and many domestic medical institutions often need to negotiate and sign contracts with international insurance companies one by one in order to be recognized by international commercial insurance institutions. In order to strengthen medical quality management, many hospitals in China chose to participate in international certifications such as JCI in the United States and ACHS in Australia.

　　Now, after Shenzhen issued the first "international" hospital evaluation standard, it will be beneficial for China’s high-level medical institutions to integrate into the international market by using "domestic standards". Domestic hospitals can choose to pass this standard, and the quality and safety of hospitals can be recognized internationally, especially directly by international commercial insurance institutions. Customers who purchase international insurance can directly "brush commercial medical insurance" and seek medical treatment in hospitals that have passed the "International Standard (2021 Edition)" certification.

　　In the future, this standard will be popularized and applied in medical institutions in Greater Bay Area, including hospitals in Hong Kong and Macao, to promote the convergence of medical homogenization and cross-border medical service rules in Greater Bay Area, and to realize the intercommunication of people flow, logistics, capital flow and information flow in the Bay Area.

　　At present, "International Standard (2021 Edition)" has been welcomed by some hospitals. Four public hospitals in Shenzhen (Shenzhen Hospital of Southern Medical University, Shenzhen Hospital of Hong Kong University, Union Hospital of Huazhong University of Science and Technology, Shenzhen People’s Hospital of Longhua District) plan to take the lead in participating in the evaluation in the near future.

　　Integrate the "Three-A" standards with international standards, and the standards "only rise but not fall"

　　Xu Xiaoping, chairman of the Evaluation and Research Center of Shenzhen Weijian Hospital, introduced that the International Certification Standard for Hospital Quality (2021 Edition) is an upgrade of the "Three-A" standard and a fusion with international standards. On the basis of the National Accreditation Standards for Tertiary Hospitals (2020 Edition) and the National Detailed Rules for the Implementation of Accreditation Standards for Tertiary General Hospitals (2011 Edition), the center was compiled in nearly one year according to the principle of "standards only go up, not down", referring to relevant international documents and comparing with the requirements and principles of ISQua.

　　The standard is divided into three chapters (hospital function and task, patient safety and medical service and medical quality, hospital management and operation), with a total of 186 evaluation items. Each evaluation result is divided into five grades (excellent, good, up to standard, substandard and unwell), which are reviewed every four years, emphasizing continuous improvement.

　　The advantages of this standard are lean in quality and safety, global in risk management, systematic in occupational safety, meticulous in humanistic care and frank in doctor-patient relationship. For example, in terms of employees’ occupational safety, the "Three-A" standards mainly emphasize radiation safety, biological safety and chemical safety management, while the "International Standard (2021 Edition)" adds other safety clauses such as laser safety, manual handling operation, workplace violence and employee health intervention on this basis, and comprehensively requires the establishment and improvement of occupational safety and health management system.

　　Foreign mainstream medical evaluation standards attach great importance to humanistic care and public disclosure. The "International Standard (2021 Edition)" has also joined the requirements of Australian ACHS and other international standards on "public disclosure". "In the international medical certification standards, it is necessary to actively inform and disclose the patients or the public after the hospital has an adverse event. In the past ten years, Shenzhen Hospital of the University of Hong Kong has been at the forefront of China in this respect and has been welcomed by the public. "

　　Cross-border medical exploration in the "first demonstration zone" is a major breakthrough in the reform of comprehensive authorization.

　　The International Accreditation Standard for Hospital Quality (2021 Edition) originated from the successful practice of "one hospital, two systems" in Shenzhen Hospital of Hong Kong University. As a pioneer of public hospital reform and medical cooperation between Shenzhen and Hong Kong, Shenzhen Hospital of the University of Hong Kong passed the international certification of ACHS (Australian Medical Service Standards Committee) in the third year of its opening (2015), and passed the accreditation of domestic top three hospitals in the fifth year of its opening (2017), becoming the first hospital in the mainland to pass both ACHS certification and top three accreditation. Compared with the experts in Hong Kong, the hospital found that the domestic standards for the top three accreditation are even more detailed and strict in terms of medical quality and safety requirements. The top three accreditation can be internationally recognized on the basis of integrating some foreign excellent practices, and the hospital has thus developed the idea of "top three" internationalization, which has been supported by provinces, cities and countries.

　　In 2019, the CPC Central Committee and the State Council issued "Opinions on Supporting Shenzhen to Build Socialism with Chinese characteristics Pilot Demonstration Zone", and in 2020, the General Offices of the General Office of the Central Committee of the CPC and the State Council issued "Implementation Plan for Shenzhen to Build Socialism with Chinese characteristics Pilot Demonstration Zone for Comprehensive Reform (2020-2025)", all of which put forward the reform task of exploring the establishment of a hospital evaluation and certification standard system in line with international standards. With the strong support of the National Health and Wellness Commission and the Guangdong Provincial Health and Wellness Commission, in December 2020, Shenzhen decided to set up a non-profit third-party evaluation and evaluation research center-Shenzhen Weijian Hospital Evaluation and Evaluation Research Center, which absorbed senior certification experts at home and abroad, set up an evaluation expert database, standardized international rules, and integrated domestic evaluation practice, and compiled the International Accreditation Standard for Hospital Quality (2021 Edition), which was the first to realize the hospital evaluation standard.

　　In February, 2022, the International Accreditation Standard for Hospital Quality (2021 Edition) passed the international standard certification of ISQUEEA, and became the first internationally certified hospital accreditation standard in China.

　　ISQua is the only organization in the world that certifies medical accreditation bodies, and it is called "examiner" of medical accreditation bodies. More than 60 third-party medical accreditation bodies in the world have been certified by Isquaea, including JCI of the United States, KTQ of Germany, ACHS of Australia, DNV of Norway, and Taiwan, China Medical Quality Council.

　　[Reuters, Beijing, January 24] The Spring Festival Gala broadcast by China National Television today paid tribute to the people of Wuhan and the medical staff fighting against the coronavirus crisis and encouraged them to win in the fight against the epidemic.

　　According to tradition, hundreds of millions of people will sit around the TV to watch the Spring Festival Gala. Since the first Spring Festival Evening was broadcast in 1983, this four-hour party, which included sketches, music and dance, has been a must-see TV program.

　　This year, a special program was added to this well-planned party at the last minute, and the time was arranged at the front of the whole party.

　　The host of the program extended his best wishes to the front-line medical staff and Wuhan citizens. The hosts shouted, "We will win!"

　　In a montage video, doctors and nurses wear protective clothing and work hard to take care of patients. Later, the hosts read more words of encouragement.

　　Bai Yansong, one of the most famous hosts of CCTV, said at the party that the program about the virus epidemic was prepared temporarily shortly before the official launch of the Spring Festival Evening.

　　Bai Yansong said, "Remember, we love you! Not only today, but also every day in the future. " At the same time, the camera lens switched to an audience at the scene, and tears rolled over her face.

Accompanied by passionate music and more pictures of medical staff wearing protective clothing on the big screen behind them, Kang Hui said: "There is no hurdle that we can’t get through!"

　　For many people in Chinese, the Lunar New Year, which officially started this Saturday, is the most important festival of the year. However, this year’s celebration of the Year of the Rat was overshadowed by the virus epidemic.
