CCTV News:The National Stadium Paralympic Ice Hockey Competition entered the final stage of medal competition. Outside the stadium, the most advanced medical care and technology are guarding the dream of every paralympic athlete. Recently, CCTV reporters from the General Station approached the medical team of the National Gymnasium. Let’s follow the reporter’s lens to explore these medical technologies that protect the health of athletes on the field.

　　Before the competition began, the medical staff of the National Gymnasium were conducting a system connectivity test on individual medical equipment. Through this equipment, the real-time high-definition images of medical treatment in the stadium can be transmitted to the medical terminal of Beijing Winter Paralympic Games.

　　Once the emergency button of individual equipment in the venue is triggered, at the medical system terminal of BOCOG, more than 200 experts from more than 20 hospitals will conduct online and offline real-time consultation on emergencies at any time.

　　In the medical control room of the National Gymnasium, the situation of the stadium, clinic and ambulance is displayed on the big screen in real time. During the Games-time, based on 5G high-speed transmission technology, all venues including Beijing, Yanqing and Zhangjiakou, as well as the Medical Center of Beijing Winter Olympics Organizing Committee, have realized real-time sharing of medical resources and first aid information.

　　In addition to the telemedicine system created by the 5G signal, on the ambulances equipped in each venue, the latest medical equipment is also helping medical workers to race against time and grab the prime time for treatment. In the ambulance, the reporter saw that in addition to the negative pressure device to meet the epidemic prevention needs, the car was also equipped with ECG monitoring device, defibrillator and tracheal intubation equipment. Different from the large-scale equipment with the same function in the hospital, the biggest feature of all these equipment is light weight and convenience.

In the course of football in China, foreign aid has always played a decisive role. Among them, the 33-year-old foreign aid Jin Yuyou from South Korea has become a leader in the Super League. According to the Korean media OSEN report, Jin Jianyou received quotations from many giants in Japan’s J League and South Korea’s K League when his contract was about to expire, and is expected to leave the Super League for free.

Jin Jianyou’s career began in 2010, and he started his own football tour in the J League team Bird Habitat Sandstone. He also played for South Shui Yuan’s Samsung and Jin Quan’s Shangwu, and has rich experience in Korean leagues. In 2022, Jin Jianyou joined Chengdu Rongcheng with his mentor Xu Zhengyuan and quickly became the backbone of the team. According to sources, even J-League teams qualified for the AFC Champions League have taken a keen interest in Jin Jianyou, taking a fancy to his advantages of being fluent in Japanese and competent in multiple positions.

This season, Jin Jianyou played 23 Super League games for Chengdu Rongcheng, contributing 6 goals and 4 assists. Last season, he also handed in four goals and seven assists. After two seasons, Jin Jianyou scored 21 goals in the Super League, showing his excellent offensive ability. It is worth mentioning that the new Football Association will soon follow up the AFC Champions League foreign aid policy, and the Super League is expected to restart Asian foreign aid. At this critical moment, it will undoubtedly be a great loss for China football to let Jin Guiyou go.

Jin Jianyou’s play in Chengdu Rongcheng can be described as incisive, and his departure will undoubtedly make the team and fans feel sorry. However, the vagaries of the football world make all this unpredictable. Jin Guiyou’s free departure may bring opportunities to other teams in the Super League, but for China football, it is undoubtedly a loss if he finally loses such a powerful player.

Among Jin Guiyou’s potential next home, teams from J League and K League have offered him olive branches. This Korean foreign aid who can speak fluent Japanese is likely to continue his brilliant career in Asia. While facing great competitive pressure, the Super League team also needs to constantly adjust its strategy and plan for the team’s future. Under the background of AFC Champions League policy adjustment, Chinese Super League teams need to increase the signing efforts and cultivate more powerful Asian foreign aid. Although it is a pity that Jin Guiyou will leave, it may inspire the team and the Football Association to change their signing strategies. Let’s look forward to the performance of China football in the future and see if Chengdu Rongcheng can make up for this vacancy and reproduce its glory. (Laoqiu Super Ball Review)

Reporter Han Bing reports With the national football team’s 1-1 draw with Australia, the top 12 matches ended in six rounds, which ushered in an interval of more than two months. With four rounds left, China is 11 points behind the top Saudi Arabia, 7 points behind the second Japanese and 6 points behind the third Australian, and the qualifying probability is basically zero. After the game, head coach Li Tie also held a 32-minute press conference, which was a comprehensive summary of the first six rounds. Unfortunately, Li Tie’s "personal summary", as before, has caused widespread controversy. The next day, Li Tie continued to publish pictures and texts on social networks, which once again set off a wave of public opinion.

Against the background that the Top 12 Competition has come to an end, facing the unspeakable outstanding achievements of the national football team and various controversies caused by the words and deeds of head coach Li Tie, the China Football Association must give an explanation to the national football team, the relevant parties in the league and the fans who love China football as soon as possible.

Earlier, the media said that the renewal of the contract between the Football Association and Li Tie was to "train handsome" for the 2026 World Cup qualifiers. After six games before the Top 12, from tactics to employing people, and then to the controversy that triggered off-court public opinion storm, it became a question whether it is necessary for Li Tie to continue to "practice". The probability of qualifying is almost zero. Under the background that the remaining four top 12 games next year are only meaningful for training, it is necessary to have a clear conclusion from whether the coach will stay or not, how to use the naturalized players, and whether the Chinese Super League will continue to make way for the top 12 games. After all, the national football team is about to prepare for the 2023 Asian Cup, followed by the 2026 World Cup qualifiers. It is not too late to make up for the coach’s choice. Now, the national football team will have at least three years to bring a new atmosphere to the new coach.

The World Cup qualifiers are the most important events of the national football team. It is hard to understand how to "train handsome" in such an important event. After all, even if the national football team originally had a low probability of qualifying for strength reasons, it is not the reason to "train handsome" with the most important events. What’s more, in terms of preparation, training, personnel selection, tactics and contingency, Li Tie has shown his incompetence as a national football coach, which has also caused more unnecessary disputes outside the stadium. If the national football team wants to make a breakthrough in the local Asian Cup in 2023 and the World Cup qualifiers in 2026, it should make a decision and make a choice early.

The great controversy caused by Li Tie’s use of naturalized players has proved that he misjudged the ability of naturalized players, which directly affected the national football team’s record and led to the complete disillusionment of the qualifying hope that there was still a chance. Regardless of foreign or local handsome, nationality is not an amulet, but whether it has the ability to make the national football performance go up a storey still higher is the key. It is an act of putting the cart before the horse to deprive the national football team of the most important growth opportunity just for the sake of "training handsome", and the China Football Association must root out the root cause.

If the coach’s ability is insufficient, we can still give Li Tie more time. However, Li Tie’s prejudice against naturalized players failed to maximize the strength of the national football team, which also directly affected the performance of the national football team. In the face of his mistakes in employing people, tactics and coping with emergencies, Li Tie failed to take the initiative in many statements. Instead, he blamed the poor performance of the national football team on many objective factors, such as losing the home court, long-term training, naturalized players’ physical condition and so on, without the sense of responsibility and overall situation that the national football coach should have.

What’s more, when the national football team almost lost the hope of qualifying because of his personal mistakes, and the public opinion and fans were extremely dissatisfied, Li Tie, as the coach of China national team, repeatedly posted inappropriate pictures and texts on social networks, causing even greater public controversy. Even when the outside world was generally dissatisfied with the performance of the national football team, advertisements were posted on the homepage of personal social networks, and pictures suspected of infringing on the rights and interests of national football sponsors were deleted after being pointed out by the media. Judging from the action of deleting pictures, Li Tie released Weibo, who was suspected of product placement, the day after the top 12 competition. It was definitely not approved by relevant parties, and the advertising behavior suspected of infringing the rights and interests of the official equipment sponsors of the China Football Association was even more unacceptable to public opinion and fans. Li Tie caused such a huge controversy inside and outside the stadium, with poor performance and shirking responsibility. Is he still suitable to continue as the coach?

China Football Association must also face more thorny problems caused by the Top 12 matches, including the resumption of the Super League, whether the Super League will continue to make way for the Top 12 matches next year, and how to deal with the messy wage crisis in the Super League. All these require the Football Association to take the attitude of being responsible for football in China, assess the situation, and come up with a solution that conforms to the objective laws of football as soon as possible and can minimize the negative impact on all parties concerned.

In a word, it is the eventful autumn of football in China, and more than two months have been reserved for the Football Association in the Top 12. For the future of football in China, it is time for the Football Association to make a decision. ???

Special feature of 1905 film network　After waiting for 12 years and 4727 days, it’s finally here!

At present, the film has been officially released nationwide, and the total box office of pre-sale has easily exceeded 100 million.

In this sequel, we will follow the hero and heroine Jack and Neytiri, who are married and have children, to dream back to Pandora, the magical planet, and witness them fighting for their homeland again.

More specifically, the director also unlocked a brand-new map for the audience — — Pandora’s sea world.

Beautiful underwater landscape, various marine life and breathtaking underwater adventure, just like the title "The Way of Water", the film also presents an amazing underwater visual feast.

As we all know, Cameron has a deep emotional connection with the ocean. Avatar: The Way of Water is also regarded by him as "a love letter to the deep sea."

However, Cameron also bluntly said that the difficulty of underwater special effects has increased exponentially. "No matter what problems encounter water, they are ten times more difficult than before."

As a global leader in film technology innovation, how did Cameron overcome many difficulties and create this underwater spectacle for the audience? In order to answer this question, we also specially interviewed Sun Xun, a well-known underwater photographer in China, who was in charge of underwater shooting of such films, and jointly revealed the unknown stories of "water drama" shooting at home and abroad.

Only Cameron can do it.

What are the highlights of the underwater shooting of Avatar: The Way of Water?

Looking back 13 years ago, almost single-handedly, it set off a wave of 3D movies around the world, and also promoted the comprehensive innovation of virtual shooting technology.

Cameron has been at the forefront of film technology for 40 years. When the existing technology can’t keep up with the settings in his mind, it is his methodology to develop new hardware and new systems, and this time is no exception.

The difficulty of Avatar: The Way of Water lies in how to complete large-scale and high-quality motion capture underwater. Before this, a series of blockbusters, such as Avatar, used the method of "dry filming and wet filming".

Sun Xun explained to us that the so-called "dry shooting wet" is actually a kind of "lazy" technology, that is, the actors shoot on the land stage, hang Weiya to simulate the movement in the water, and add smoke, filters and post-effects to create the underwater effect. The advantage is that the operation and cost are controllable, but the disadvantage is that it is not real enough, such as clothes and hair swinging does not conform to gravity.

The behind-the-scenes team also suggested this method to Cameron, but out of the pursuit of realism, Cameron insisted on performing and capturing in the water.

To this end, the team had to spend five years to upgrade a whole system, and it took eighteen months to complete all the underwater performance capture and shooting, with the aim of 100% restoring the expression and underwater state of real actors.

This technique was also tried in Cameron’s production, and the scene where Alita plunged into the water to find the mecha was captured by stuntmen performing underwater.

The main venue for the underwater performance of Avatar: The Way of Water is a huge water tank with a capacity of 900,000 gallons, which can reproduce the real marine environment, including water waves and waves.

The water tank is also equipped with a propeller system called "runway", which consists of two marine propellers with a diameter of 6 feet, and is used to create waves in the water tank.

In order to make the performance capture technology work underwater, the water quality must be clear and transparent. Cameron wanted the actors and the camera crew to shoot in scuba diving suits, but found that the breathing apparatus would cause disturbance to the water body.

In this way, there is only one choice: everyone who works in the water tank must hold their breath. Therefore, the actors learned free diving under the guidance of internationally renowned Kirk craik.

Among them, 73-year-old sigourney weaver can hold her breath statically for 6 minutes and 30 seconds after training. He won the championship in 7 minutes and 14 seconds, which also broke the record of Tom cruise’s single free dive shooting.

Of course, some difficult movements need synchronized swimmers and gymnasts to achieve. According to statistics, the crew, including actors, photographers and security officers, completed 200,000 free dives to make this blockbuster.

The underwater 3D camera used in Avatar: The Way of Water is also very exquisite. It is a DeepX 3D photography system developed by Australian photographer Pavel Acto, which can greatly improve the image quality and clarity, and at the same time reduce the distortion of ordinary underwater cameras.

Later special effects are also essential. Cameron once again cooperated with Vita Studio to restore the subtle expressions of each character and create an immersive water world wonderland.

Cameron described it this way: "Whether tons of water are stirred by the fins of large creatures or small raindrops are trickling down someone’s cheeks, we have to study the trajectory of water. At the time of filming, we were doing water simulation. The complexity of this film goes up five steps. The tools we developed are of great significance to the entire special effects industry. "

No matter in the early or late stage, the efforts of the creative team all point to the same key word, that is, "reality", that is, to bring the audience the ultimate visual experience like a documentary.

However, Cameron also reiterated that technology must serve the arts. "People’s tears when watching Titanic are not for special effects. In Avatar: The Way of Water, we should also strive to balance technology and emotion."

Go ahead in exploration

Underwater shooting in China has "set sail"

There is such a line in the movie: "The way of water connects everything, transcends life and death, and remains unchanged forever." Indeed, the ocean accounts for 71% of the earth’s surface area, and the deep blue sea breeds the source of life, but also hides the infinite unknown.

It is this yearning for the mysterious ocean that drives generations of filmmakers to explore underwater beauty with their lenses. As early as 1954, in the film "Black Lake Demon Pond", pioneers began to try underwater film machine photography. In the following 70 years, technology and equipment have been constantly innovated and upgraded.

In contrast, the underwater photography industry in China started relatively late. Sun Xun told us that when he entered the business around 2014, the domestic underwater photography team was still very scarce.

Over the years, he and his team have participated in the shooting of a series of films such as Shadow and Fire Hero, and witnessed the progress of the industry all the way. Behind the scenes, every play is a process of constantly overcoming difficulties.

　

Underwater lens in Shadow

For example, in "Heroes of Fire", in order to create a realistic explosion effect of oil pipelines, the art and props group "modulated" pieces of sticky oil with starch and pigments, and also put in fresh scallops, oysters and other seafood, and the flame was also really burning.

After two days of shooting, cameras, diving equipment and everyone’s faces were covered with black oil, which was a great challenge for photographers.

Starring "Care for You" is to do enough work in aesthetics. Sun Xun recalled that the director attached great importance to the aesthetic feeling of the lens and showed the emotions of the characters with light and shadow in the water, which was a valuable attempt of domestic films in underwater photography aesthetics.

In the film directed, there are also a lot of real water plays. In order to pursue real visual effects, the crew also made a special trip to the Baja studio in Mexico where Titanic was filmed.

When filming the forced landing of the plane, the team specially purchased a retired Airbus 320 plane and took a real shot in the reservoir, which truly restored the whole process of the plane sinking. Lin Chaoxian also personally dived to 18 meters underwater with him to film the desperate escape process.

Sun Xun said frankly that in daily work, the most common problem is the crew’s lack of experience in underwater shooting and lack of cognition. They often have to communicate with each other from scratch and adjust the shooting plan step by step.

"The simplest example, many directors think that throwing people into the water after murder will sink, but it is not like this. People should be floating. What actions can be done and what can’t be done in the water? Many crews lack pre-evaluation, which is the most common problem we encounter, "Sun Xun said.

Sun Xun in the filming.

Of course, with the continuous enrichment of shooting experience, domestic teams have also made visible progress in this field. For example, in the new film "She Disappeared", there is no small breakthrough in underwater shooting.

"A large part of this play is underwater. On the one hand, there are many scenes, not just a few shots, but the plot of the whole play. On the other hand, the scheduling is particularly perfect and the completion is very high. I am very much looking forward to the release of this film."

He also revealed that the two leading actors went into battle in person and worked together to complete the underwater scene. "Zhu Yilong is quite experienced in diving. NiNi has a collarbone injury, but he also took a shot with diving equipment on his back. Both actors worked hard."

Sun Xun also specifically mentioned that in recent years, the development of underwater photographic equipment in China is remarkable. Many equipment used by foreign filmmakers are made in China, but there is still room for improvement in industrial process, systematization and detail control.

More importantly, he hopes that film creators can boldly fly their imaginations and bravely try things that no one has tried before. "Whether it is the progress brought by hardware upgrade or the upgrade of script creation, we look forward to working with the director to complete something that really makes people shine."

This is exactly what Cameron and Avatar: The Way of Water mean to the film industry. Maybe it can’t surpass the box office peak of its previous work in the end, but it won’t detract from its contribution in the field of technological innovation.

"Cameron is a person who rushes to the front line. He is always exploring things outside the circle and challenging the limits of technology. It’s a very exciting thing for a technical controller like us, "Sun Xun said with emotion.

Just like in the documentary "Deep Sea Challenge", Cameron successfully dived to the bottom of the Mariana Trench by driving the "Deep Sea Challenger" and set a world record for single-person deep diving:

"We have to do what others can’t do."

Yesterday’s weather situation

There were large-scale thunderstorms in our province from noon to night yesterday, with heavy rains in northern and western Zhejiang, and heavy rains in Hangzhou, Huzhou, Jinhua and Quzhou. From 08: 00 on the 19th to 08: 00 on the 20th, there were 157 townships (streets) with rainfall exceeding 50 mm, of which 22 exceeded 100 mm, the maximum rainfall intensity at a single station was 179 mm in Changxing Peace, and the maximum hourly rainfall intensity was 120 mm in Changxing Beach Longqiao. In addition, there are 7-9 thunderstorms and strong winds in northern Hangzhou and northern Shaoxing.

Today’s rainstorm is still the same?

Speaking of the torrential rain in these two days, I have to mention Typhoon Taili. Although Taili is far away from our province, the water vapor it brings to our province is quite rich. Because of the good water vapor conditions at the lower level, coupled with the unstable subtropical high and the influence of small weather system, the uplift movement is strong, and the convection developed in our province at noon is just in a strong period around the evening peak.

The picture shows the rain in Shangcheng Ding Qiao on July 19th.

Many netizens can’t help asking: Does it rain every time after work?

What about today?

Judging from the current weather situation, the convective conditions in this afternoon are still good, the water vapor and unstable conditions are good, and the convective conditions in northern Zhejiang and coastal areas are relatively better. Strong convective weather is local, and the local short-term rain is strong. You can pay attention to the latest forecast and early warning information released by the local meteorological department.

Recent weather

Scattered thunderstorms in the afternoon in the next three days.

On the 23 rd, due to the influence of the high-altitude trough, there was an afternoon thunderstorm.

"I’ dug’ another mobile phone. Whose is this?"

"My, my! Hold it for me first … "

This is a fancy game full of fun. Everyone grabs potatoes with all their heart and soul, so that some people’s mobile phones slip out of their pockets and fall to the ground without noticing it.

On March 8th, wuxuan county Municipal Bureau of Human Resources and Social Security and Dongxiang Town Trade Union jointly launched a series of activities to help rural revitalization. More than 100 women and enthusiastic male guests punched in the potato planting base in Luliang Village, Dongxiang Town, and had an unforgettable March 8th Women’s Day.

At the event site, laughter and laughter came one after another. Not much to say, there are pictures to prove it.

Dig up potatoes

Input is the greatest respect for the game. Tear off the vines and pull open the soft soil layer, and one khaki potato will appear in front of you. Returning to the pile, bagging and carrying it to the weighing place, although these girls are usually gentle and seemingly helpless, they are also good at farm work.

The activities include potato "big" competition, potato "quantity" competition and potato peeling competition. In each group, the largest potato is selected for volume measurement, and which group has the largest potato is compared; In the specified 10 minutes, see which group has the heaviest sum of potatoes; In the specified 1 minute, see which group peeled potatoes quickly and well.

After a fierce competition of "big", "quantity" and "fast", the top three winners were decided respectively, and half a bag of potatoes was awarded.

Half a bag of potatoes, weighing at least 50 or 60 Jin, is really "rewarding".

At the end of the activity, everyone will also make the dug potatoes into various delicacies. The dishes are rich and exquisite, and the aroma is diffuse, which is mouth-watering and memorable.

Dongxiang Town has a warm climate, and the cultivated land is mostly alluvial sandy loam, which is fertile and breathable, and has natural advantages for potato growth. The yield of commercial potatoes is 3000-6000 kg per mu. At the end of last year, the potato planting area in Luliang Village was 302.3 mu, and potatoes were basically planted in the winter fallow fields, covering 100% of the farmers in the village who worked at home.

Nowadays, potatoes have ushered in the harvest season. At present, the market price of potatoes is about 2.4 yuan/kg, and the average income per mu is 2,400 yuan, calculated by the yield of 3,000 Jin per mu. Excluding the cost, the net profit per mu is above 1000 yuan, which effectively increases farmers’ income and promotes rural revitalization.

"Family, I am now in the potato planting base in Luliang Village, Dongxiang Town, wuxuan county …" On the day of the event, Dongxiang Town made full use of the advantages of "internet plus" and invited the network anchor to bring the goods live with the theme of "claiming a piece of land and harvesting a hope".

Through the way of "webcast+interaction", consumers can directly claim and dig potatoes online, understand the growth process of potatoes in an all-round way, establish close ties with farmers, further broaden the sales channels of agricultural products, drive local farmers to increase their income and get rich, let "Golden Bean" take advantage of the east wind of live broadcast with goods, and activate a pool of spring water for the integrated development of "agricultural industry+red research+rural leisure".

Soft shoulders shoulder heavy responsibilities, and women are blooming. There is a kind of beauty called "her strength". There is more than one side of her life. She is a mother, a daughter and a companion … She is gentle and delicate, sincere and tenacious, elegant and intellectual …

　　Little "potato king", fire again and again. The Ministry of Agriculture recently issued "Guiding Opinions on Promoting the Development of Potato Industry", proposing that by 2020, the potato planting area will be expanded to more than 100 million mu, the proportion of varieties suitable for staple food processing will reach 30%, and staple food consumption will account for 30% of the total potato consumption.

　　Therefore, as soon as this Guiding Opinion was released, it triggered a heated discussion in the society. Potatoes, originally a home-cooked dish on the dining table, are shredded potatoes with vinegar, fresh potatoes and stewed beef with potatoes … … I’m afraid we can’t count how many potatoes we have eaten these years. Many people are puzzled. Why should we advocate the development of potato staple food? Is there not enough food to eat? How to eat potatoes as a staple food? How to promote the potato industry development?

　　From "non-staple food" to "staple food", why does potato "counterattack"?

　　"The development of potato staple food is not to let everyone directly eat potatoes as staple food." Dai Xiaofeng, director of the Agricultural Products Processing Institute of China Academy of Agricultural Sciences, explained that the development of potato staple food is to process potatoes into staple food products such as steamed bread, noodles and rice noodles suitable for China people’s consumption habits, so as to realize the transformation from non-staple food consumption to staple food consumption, from raw material products to industrialized series of finished products, and from food and clothing consumption to nutritional and healthy consumption.

　　Is it not enough to eat potatoes that are used to being eaten as vegetables as dry food?

　　Zeng Yande, director of the Planting Department of the Ministry of Agriculture, said: "China’s grain has been harvested for 12 consecutive years. The implementation of potato staple food development does not mean that there is a shortage of the three major rations. However, from the perspective of supply-side structure, rations appear ‘ Three quantities increase together ’ Phenomenon, especially the pressure of corn destocking, so it is necessary to reduce the corn planting area. From the demand side structure, with the improvement of living standard and consumption level, the pursuit of nutrition and health has become a consumption trend, while the market structure of agricultural products is relatively simple. Therefore, incorporating potatoes into the staple food family will help promote the effective docking between the supply side and the demand side of agriculture. "

　　In addition, promoting the development of potato staple food is also conducive to alleviating the pressure on resources and environment and realizing the sustainable development of agriculture. Potato is cold-resistant, drought-resistant, barren-resistant, and has wide adaptability, so it is easier to plant.

　　So, why did you choose potatoes as the staple food?

　　The history of food has proved that potato is a staple food suitable for human needs. Yu Xinrong, Vice Minister of Agriculture, said that in Europe and America, potatoes have been the staple food for hundreds of years. As far as China is concerned, potatoes have become the staple food on the table of ordinary people in parts of Shaanxi and Ningxia in the northwest and parts of Northeast China. With the development of economy, consumer demand is increasingly diversified. In order to comply with this trend, we should constantly realize the diversification of staple food and promote potato staple food throughout the country.

　　The most exciting thing is the nutritional value of potatoes. Wang Xiaohu, director of the Institute of Food and Nutrition Development of the Ministry of Agriculture, said that through testing, it was found that potato staple food contains all seven kinds of nutrients needed by the human body, and also makes up for the lack of vitamin A and vitamin C in the daily staple food. The vitamin content in 100 grams of potato is equivalent to 7 apples, or one and a half tomatoes, and the potassium content is equivalent to two bananas.

　　Liang Xisen, chairman of Himsen Group engaged in potato breeding and industrial development, told the reporter: "99% of the compressed biscuits eaten by the troops are all potato powder, and the food of astronauts in space is also processed from potato powder. The nutritional value of potato powder can be seen."

　　Wang Xiaohu said that the experiment conducted by the project team in Inner Mongolia showed that sticking to eating steamed bread with 30% potato flour made people healthier in terms of blood sugar, blood lipid and insulin.

　　When can I eat potato steamed bread?

　　"I just heard on the news that potatoes are staple food, but I have never seen potato steamed bread in the supermarket. Where can I buy it?" Speaking of potato staple food, Aunt Wang, a Beijing citizen who is shopping for food in the supermarket, is very curious.

　　"The nutritional value of potato whole powder is relatively high, and the general whole powder content is 20%— 30% of potato steamed bread is delicious. " Liang Xisen said that in June last year, Himsen Group began to produce potato steamed bread in factory, including one local ordinary steamed bread in 0.5 yuan and one potato steamed bread in 1 yuan. The products were in short supply and sold in large quantities to Tianjin, Jinan and other places, and the Beijing market was slowly developing.

　　Not only steamed bread, but also 154 kinds of potato staple food products in six categories were displayed on the spot at the high-level seminar and achievement conference of potato industry development held by China Academy of Agricultural Sciences. In addition to popular staple foods such as steamed bread and noodles, there were instant bean paste cakes, unique chrysanthemum cakes and delicate and delicious cookies & HELIP; … The delicious taste makes the tasters full of praise.

　　"Take the staple food products with potato flour accounting for 40% as an example. In the next 10 years, with the speed of 20%, the consumption capacity of traditional staple food products of potatoes can reach about 20 million tons, and the consumption capacity of leisure products can reach about 8 million tons." Wang Xiaohu said that the potato product market will be a vast "blue ocean".

　　"It is imperative to accelerate the industrialization of potatoes." Yu Xinrong said that potato industrialization has made progress in stages, but to meet the huge potential market, it is necessary to start from all aspects and constantly accelerate the pace of industrialization.

　　"Breeding innovation needs to be strengthened, especially the breeding of potato varieties suitable for staple food processing." Dai Xiaofeng said that the dry matter content of potato is obviously different because of different producing areas and varieties. For example, the yield per mu of some varieties in Shandong producing areas can reach 3-mdash; 4 tons, but the starch content is low and the flour yield is low; On the contrary, Gansu "Yidianhong" with high starch content has high flour yield, but the yield per mu is only 1-mdash; 1.5 tons. Experts say that how to cultivate varieties with high yield and high starch content is another key to industrial development.

　　Wang Xiaohu introduced that the Academy of Agricultural Sciences has built a basic information database of 245 potato varieties and determined the potato screening system. A total of 18 varieties suitable for staple food development in 4 ecological regions were screened out to speed up the solution of this problem.

　　"The processing problem needs to be solved." Dai Xiaofeng believes that the whole flour processing link faces two major problems. First, the strength of enterprises is weak and the production capacity is low. At present, the national production capacity is only 80,000 tons, and the actual operating rate is less than half. Second, the production cost is high. "In terms of cooked flour, the cost per ton of flour is 4,000 yuan, and the cost per ton of whole potato flour is 10,000 — 12 thousand yuan. How to solve the problem of high cost will be the focus in the future. "

　　"The staple food products should be more abundant." Yu Xinrong said that enterprises can sensitively tap the market demand and innovate more diversified potato staple food products. It is understood that potato steamed bread has been sold in more than 600 supermarkets in Beijing, Tianjin and Hebei, but to meet the eating habits of different regions and different levels of consumer groups, enterprises need to increase the intensity of innovative products.

　　Potato industrialization will not compete with the three staple foods for land.

　　China’s arable land area is limited, and the constraints of resources and environment are getting tighter and tighter. Will vigorously promoting potato industrialization and expanding potato planting area form a situation of competing with the three staple foods for land and water?

　　"Promoting the potato industry will not compete with the three major grains for water and land." Zeng Yande said that potato production should be expanded according to local conditions by using winter fallow fields in the south, arid and semi-arid areas in the northwest and groundwater overexploitation areas in North China, and efforts should be made to form a situation in which potatoes, rice, wheat and corn complement each other and develop in a coordinated way.

　　"Increasing the potato planting area coincides with adjusting the planting structure." Zeng Yande said that at present, the corn production capacity is over-capacity. In the past 12 years, the national corn planting area has increased by more than 200 million mu, of which the "sickle bend" area accounts for nearly 40%. In the future, the potato planting area with less water demand and relatively high yield can be increased in the "sickle bend" area.

　　Potato industrialization should be promoted step by step with emphasis. Yu Xinrong said that the future will be promoted according to the overall layout of "one main center and seven sub-centers". Beijing, as the main center, will become the research and development technology center of potato products, forming a number of leading product formulas and processing technologies. Promote potato development in Northeast China, East China, Central China, South China, Southwest China and Northwest China step by step, cultivate consumer groups, expand consumer markets, and develop potato products with regional characteristics according to regional consumption habits to meet consumer demand.

　　The supporting policies for potato production need to be gradually implemented. Zeng Yande introduced that the relevant departments will improve the potato production support policies and implement policies such as agricultural support and protection subsidies and agricultural machinery purchase subsidies. Encourage all localities to implement land, electricity, water, gas and other price concessions for potato processing enterprises. Increase investment in potato production, support seed potato production, storage facilities construction, standardized production technology promotion, market and information services. Actively explore the credit guarantee and insurance mechanism of potato industry, guide financial institutions to expand credit support for potato staple food industry, increase credit lines and implement preferential interest rates.

　　"But financial capital investment only plays a guiding role." Dai Xiaofeng said that the development of potato industry involves many links such as scientific research, production, processing, circulation and consumption, and it is a complex systematic project. Only by adhering to the combination of government guidance and market regulation, giving full play to the leading and exemplary role of enterprises, tackling key problems in the technical mode of staple food development, improving and perfecting the processing technology of staple food, and doing a good job in consumer guide, can potatoes really become the staple food on the table of the people.

　　Pay money

　　Recently, a "little cheetah" was surprised in Shidu Mountain area of Beijing, and was rescued after many searches. According to expert identification, it is a unique wild animal (sǒu) cat in the African prairie. It is not distributed in the wild in China, but appears in the mountainous area of Beijing. It is likely that nearby residents abandoned it after illegally keeping pets or the animals escaped to the mountains themselves. Wild animals are protected by law. If they are kept as pets illegally, they may cause property losses to individuals and even jail time, and may also cause great damage to the natural ecological environment, which should not be underestimated. So, which animals can’t be kept as pets? What legal responsibilities do you need to bear for buying and selling at will?

Wild animals both at home and abroad are protected by law.

　　Article 6 of China’s revised Wildlife Protection Law in 2018 stipulates that any organization or individual has the obligation to protect wild animals and their habitats, and it is forbidden to illegally hunt and kill wild animals or destroy their habitats. According to the provisions of this article, wild animals, whether they are ordinary wild animals or rare and endangered wild animals, whether they are from abroad or local, are protected by law. Especially for rare and endangered wild animals, the state adopts classified and key protection measures. Wild animals under special state protection are divided into first-class protected wild animals and second-class protected wild animals. At the same time, China joined the Convention on International Trade in Endangered Species of Wild Fauna and Flora as early as 1980, and adopted the first-class protection and second-class protection measures equivalent to those stipulated by Chinese laws for the wild animals and plants listed in Appendices 1 and 2 of the Convention.

　　The serval cat from the African prairie has been listed in Appendix II of the Convention on International Trade in Endangered Species of Wild Fauna and Flora, and it also belongs to the second-class protected wild animals in China.

　　The exotic wild animals such as serval cats are not only protected by general laws, but also strictly controlled and protected by import and export. Article 37 of the Law on the Protection of Wild Animals stipulates that the introduction of wild animal species from abroad shall be approved by the competent department of wildlife protection in the State Council to introduce rare and endangered wild animals, and an import and export license shall be obtained according to law. Customs shall carry out entry quarantine according to law, and go through customs clearance procedures according to regulations with import approval documents or import and export permission certificates and quarantine certificates. China has joined the Convention on International Trade in Endangered Species of Wild Fauna and Flora, and will strictly investigate and punish the illegal import and export of wild animals according to the treaty. Strict control of wildlife import and export transactions is also an important protection measure for wildlife at home and abroad.

　　Illegal introduction of wild animals shall be fined at least 50,000 yuan.

　　If wild at heart, a wild animal, is kept as a pet, it is easy to cause personal and property losses to himself and others due to poor supervision. For example, the serval cat, a small cat carnivore, is very fierce. In the wild, it hunts rats, birds and insects. It can bounce up to 1 meter high and 4 meters away, and the smallest territory can reach more than ten square kilometers. It is difficult to control pets like domestic cats and dogs. In the event of an accident that infringes on others’ personal and property, it is difficult to capture wild animals and it is easy to hurt others twice.

　　Article 1245 of the Civil Code stipulates that if the animals raised cause damage to others, the animal keeper or manager shall bear the tort liability; However, if it can be proved that the damage was caused by the intentional or gross negligence of the infringed party, the liability may not be assumed or mitigated. Generally speaking, this provision can be directly applied to ordinary wild animals that are not dangerous, such as small wild birds, which infringe on the rights and interests of others. However, there are special provisions in Article 1247 of the Civil Code for illegally raising dangerous wild animals such as serval cats: if dangerous animals such as dogs that are forbidden to be kept cause damage to others, the animal keeper or manager shall bear tort liability. In other words, the Civil Code imposes a higher management obligation on the breeders of dangerous animals. Once the breeding of dangerous animals is prohibited from infringing, it is not necessary to judge whether the infringed person is subjectively at fault, the breeders should bear the tort liability. In addition, Article 1249 of the Civil Code also stipulates that if an abandoned or escaped animal causes damage to others during the abandonment or escape, the original owner or manager of the animal shall bear the tort liability. That is to say, once a wild animal is kept as a pet, once it escapes, the original keeper will always be liable for the infringement until the wild animal is found back or dies.

　　Raising wild animals may not only contribute to compensate others, but also pay a higher price for taking administrative and legal responsibilities. According to Article 53 of the Wildlife Protection Law, if wildlife species are illegally introduced from abroad, the wildlife protection department of the people’s government at or above the county level shall confiscate the imported wildlife and impose a fine of 50,000 yuan to 250,000 yuan. At the same time, Article 54 stipulates that those who illegally release wild animals imported from abroad into the wild environment shall be ordered by the wildlife protection department of the people’s government at or above the county level to catch them back within a time limit and be fined between 10,000 yuan and 50,000 yuan; If it fails to catch back within the time limit, the relevant wildlife protection department shall catch back or take measures to reduce the impact, and the expenses required shall be borne by the person ordered to catch back within a time limit. Illegal breeding of wild animals abroad will be subject to administrative fines. Once abandoned or the wild animal escapes to the wild, it is very difficult to recapture it, and illegal breeders will face very high recapture costs.

　　Buying, selling and transporting wild animals are subject to punishment.

　　There is no killing without buying and selling, and there is no hunting without trading — — This principle is not only reflected in the control of wildlife import and export, but also in the criminal legal protection. Article 341 of China’s Criminal Law stipulates that anyone who illegally hunts or kills rare and endangered wild animals under special state protection, or illegally buys, transports or sells rare and endangered wild animals and their products under special state protection, shall be sentenced to fixed-term imprisonment of not more than five years or criminal detention and shall also be fined; If the circumstances are serious, he shall be sentenced to fixed-term imprisonment of not less than five years but not more than ten years and shall also be fined; If the circumstances are especially serious, he shall be sentenced to fixed-term imprisonment of not less than 10 years and shall also be fined or confiscated. That is to say, buyers, transporters and sellers in the illegal trade of wild animals should bear criminal responsibility, and buyers and sellers should bear the same responsibility, so that buyers are afraid to buy and sellers are afraid to sell, which makes the hunters and killers in the upstream have no profit channels, which fully reflects the strict criminal legal protection of wild animals in China.

　　According to Article 1 of the Interpretation of the Supreme People’s Court on Several Issues Concerning the Specific Application of Laws in the Trial of Criminal Cases of Destroying Wildlife Resources, "acquisition" refers to the purchase behavior for profit and personal use; "Precious and endangered wild animals" refers to the first-and second-class protected wild animals listed in the national list of key protected wild animals, the wild animals listed in Appendices 1 and 2 of the Convention on International Trade in Endangered Species of Wild Fauna and Flora, and the above-mentioned species domesticated and propagated. Buying wild animals as pets naturally belongs to the situation of buying wild animals for "self-use".

　　In practice, many buyers buy overseas wild animals from the Internet out of curiosity or to satisfy their children’s wishes, such as precious and endangered parrots and lizards. Although they only watch them for themselves and do not make profits from secondary sales, they still belong to the "illegal acquisition" in the criminal law. Often, when the police file a case for investigation on the crime of illegally purchasing precious and endangered wild animals, the buyers are remorseful and call themselves ignorant of the law and make a big mistake.

　　Judge’s advice

　　Three measures to distinguish whether it is legal to sell pets online

　　For consumers, how to correctly distinguish whether the raised animals belong to the key protected wild animals must grasp the following:

　　The first is to look at the way of purchase. The way to buy pets must be standardized, and the daily supervision and management of the formal trading market is strict, so it is difficult for key protected wild animals to enter the market. For private transactions or online mail transactions, we must be extra careful.

　　The second is to look at the relevant documents and supporting materials. According to the relevant laws and regulations of the Wildlife Protection Law, individuals or institutions that raise key protected animals such as serval cats must hold the National License for Domestication and Breeding of Key Protected Wild Animals, which is generally used for scientific research before they can apply for a license. If you just want to watch and play, you can’t apply for a breeding license as a pet at home. It is an illegal act to raise serval cats without a license, and you will bear corresponding legal responsibilities. When consumers buy rare animals in the trading market, they must ask the seller for the corresponding legal source documents, import and export documents, animal inspection and quarantine materials, etc.

　　The third is to consult relevant professional departments or people with specialized knowledge. For some unusual animals, the author suggests not to raise them with curiosity. If you are not sure, you can consult the forestry department, the agricultural department and the wildlife protection center. If citizens are raising key protected wild animals, they should immediately contact and hand them over to the wildlife protection center for disposal according to law. Don’t let them loose in the wild for fear of being punished, which may cause greater damage to others’ personal, property or ecosystem.

　　Extended reading

　　Illegal introduction of wild animals from abroad is very harmful.

　　In the biological sense, due to the barrier of mountains, rivers and oceans, it is impossible for wild animals endemic to some continents to cross the Qian Shan and inhabit and breed on many continents around the world, and they can only live with other native species, forming an ecological closed-loop chain in one place. In this ecological chain, carnivores, herbivores, insects, plants, microorganisms and so on jointly maintain a long-term ecological balance. However, with the modernization of human activities, some species have traveled long distances with ships, planes and trains, surpassing the original natural species flow and being artificially introduced, breaking the balance of the original biological chain and causing ecological disasters. For example, after the introduction of rabbits in Australia, Burmese pythons in the United States and Asian carp, once the animals that lost their natural enemies adapted to the new environment, the population increased geometrically, causing serious damage to the local ecological chain.

　　China is one of the countries that are seriously endangered by the invasion of alien species. According to the Bulletin on the Ecological Environment of China in 2020 issued by the Ministry of Ecology and Environment, more than 660 alien invasive species have been found in China, including Procambarus clarkii, red imported fire ants, African giant snails, flying grasses, Chenopodium ambrosioides and other animals and plants, many of which were introduced as ornamental or pets, and spread to the natural environment due to improper management.

　　In this regard, China’s wildlife protection law also clearly stipulates that if wild animal species are introduced from abroad, safe and reliable preventive measures should be taken to prevent them from entering the wild environment and avoiding harm to the ecosystem. If it is really necessary to release it into the wild, it shall be implemented in accordance with relevant state regulations. Anyone who releases wild animals at will, causing personal or property damage to others or endangering the ecosystem, shall bear legal responsibility according to law. Therefore, keeping pets must not touch the bottom line of laws and regulations. From the point of view of protecting the ecological environment, we must consciously resist raising alien species and leave no opportunities for alien invasion.

　　Case playback

　　Liu returned home from work, chose no declaration channel when entering the country, and did not declare anything to the customs. Customs officers seized 1 pack of suspected pangolin scales, 12 suspected ivory products and 2 suspected leopard teeth in Liu’s checked baggage. After identification, the above items were 2,679 grams of pangolin scales, 1,083 grams of African elephant ivory products and African lion canine teeth. These precious animal products totaled more than 220,000 yuan. After arriving at the case, Liu voluntarily and truthfully confessed his criminal facts. He said that the animal products involved were used as supplements or as souvenirs for children. The court held that Liu violated the relevant provisions of the state prohibiting the entry and exit of precious animals and their products and evaded customs supervision. His behavior constituted a crime of smuggling precious animal products and should be punished according to law. In view of the fact that Liu surrendered himself, pleaded guilty voluntarily, pleaded guilty with a good attitude, and the precious animal products involved in the case have been detained on file and other statutory or discretionary circumstances, Liu can be given a lighter punishment according to law. The court finally ruled that Liu was guilty of smuggling precious animal products, sentenced to two years and six months in prison, suspended for three years, and fined 25 thousand yuan.

　　Judge’s prompt

　　With the deepening of international exchanges, more and more people go out to work, study abroad and travel, and smuggling cases of returned overseas people carrying precious animals or their products occur from time to time. In these cases, most of the defendants’ criminal motives were to bring precious animal products into the country and then resell them for profit, and a few were gifts to relatives and friends and personal collections. Judging from the cases accepted by the court, the targets of the crime of smuggling precious animal products include ivory, rhinoceros horn, pangolin scales, hawksbill, brown bear gall, spike and African lion canine teeth, etc., and most of the behaviors are carried with disguised luggage.

　　Maintaining the ecological balance together is of great significance to the maintenance and restoration of the ecological environment. The judge reminded people that they should consciously abide by relevant regulations and protect precious animals in their daily lives, so as to achieve harmony between man and nature.
