Football preview: leicester city is in a hot state, Atletico Madrid is in good shape, and Paris VS Montpellier.

Leicester city VS Leeds United

Leicester City defeated the Rangers away from home, and the league won 9 consecutive victories. The team’s recent performance is still hot, and it currently ranks first in the league with 39 points. Leicester city’s offensive end is active, and the stability of defense line is extremely strong. Leeds United beat Hadders at home in the last league. Although the team has experienced some ups and downs recently, it still wins more and loses less overall. At present, it ranks third in the league with 25 points. Leeds United’s offensive output is equally strong, but the defense strength is really insufficient in the near future.

Leicester city’s recent performance is still strong, and the team is currently at the top of the league. At the same time, the team’s home performance is also very strong. Leeds United is still winning more and losing less in the near future, but its overall stability is still insufficient compared with its opponents, especially the team’s recent defensive line is unstable. This time, leicester city is sitting at a strong home, and I believe there is still a chance to win the opponent’s winning streak.

Las palmas VS Atletico Madrid

Las palmas defeated Alme, the underdog in the last league, and the team has won many victories in the underdog recently. At present, it is chasing the 10th place in the league with 14 points. Las palmas’s offensive output has been strengthened, but the stability of the defense line is still insufficient. Atletico Madrid defeated Alaves at home in the last league, and the league won six consecutive victories. The overall state and stability continued to rise, and it is currently ranked third in the league with 25 points. Atletico Madrid’s offensive output has been continuously improved, and its defensive performance is acceptable, but the situation of zero sealing has been reduced.

Las palmas’s recent achievements have indeed warmed up, but the opponents are mostly weak teams in the league, and the gold content is really not high. The team’s performance at both ends of attack and defense is still obviously insufficient in the face of strong teams. Atletico Madrid’s recent performance is still strong, and the front line output is still very stable, but the defensive strength needs to be improved. This time, Atletico Madrid is a guest to challenge the opponent. I believe it is still a cinch to take away three points.

Paris saint-germain VS Montpellier

Paris Saint-Germain beat brest away from home in the last league, and the league won three consecutive victories and five unbeaten rounds. The team’s recent performance has been getting stronger and stronger, and the difference between the team and Nice at the top has narrowed to one point. The offensive output of Paris Saint-Germain has been strengthened again, but the defensive strength needs to be strengthened. Montpellier beat Toulouse at home in the last league. Although the team lost away from home before, its overall performance is still strong in the near future. At present, the team ranks sixth in the league with 15 points. Montpellier’s offensive output is still significantly strengthened, but the defensive end is also not stable enough.

The overall strength of Paris Saint-Germain is very secure, and the team’s recent achievements and performance are also worthy of recognition. In addition, the team has also found the home court advantage. The overall performance of Montpellier has also improved recently, winning several victories, but it is still difficult to compete with Paris in terms of strength. Montpellier’s visit to challenge Paris this time, I believe it is still a situation of losing less and winning.

Porto VS Lille, esto

Porto defeated Visala away from home in the last league, and won two consecutive victories in the league. Although the team suffered defeat in the face of traditional powerful teams, it still had no pressure in the face of other opponents. At present, the team ranks third in the league with 22 points. Porto’s offensive output is very secure, and the stability of the defense line has also improved. Lille, esto, lost to Polti in the last league, and the league suffered another three-game losing streak and seven rounds. At present, it only ranks at the bottom with four points. Esto Lille’s offensive performance is also relatively active, but the defense loopholes are also huge.

Porto’s overall strength is very secure, and the team is still able to face other opponents in the league, and the performance at home is also very safe. Rival esto Lille’s recent performance is still sluggish, although the offensive output is still guaranteed, but the defense loopholes are too large. This time, Porto sat at home to meet the challenge of the vice squad leader. I believe the team still has the ability to beat the opponent and win three points.

Bologna VS lazio

Bologna drew with Sassuolo in the last league. Although the team’s winning ability is not strong, it can still guarantee the unbeaten game in nine rounds, and the overall stability is acceptable. At present, the team ranks eighth in the league with 15 points. Bologna’s offensive output has strengthened, but the stability of the defense line has declined. Lazio beat Florence at home in the last league, and the league won three consecutive victories. The team has been in a strong state in the near future, and it can also win battles in a row. At present, it ranks seventh in the league with 16 points. Lazio’s offensive efficiency has improved, and the stability of the defense line has improved.

Bologna’s overall performance is quite stable. It has previously drawn against strong teams such as Juventus, Inter Milan and Naples, and it has a strong ability to score points in the main battle. Lazio, the opponent, has been strengthening in recent days, and it is also in a winning streak. Although the team’s performance in the away game is not good, most of its opponents are league teams, and they also have the ability to score points away from home. This time, the two teams collided, and Bologna, who performed very steadily, still had a chance to defend the unbeaten home, and the possibility of a draw between the two sides was not small.

Awesome, my C919! The first flight of China big plane is in sight.

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

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

  — — Wu Guanghui

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

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

  ① Rigorous test to ensure safety.

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

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

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

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

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

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

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

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

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

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

  ②C919 is genuine China goods.

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

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

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

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

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

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

  ③ Have a number of scientific and technological innovations.

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

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

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

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

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

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

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

How should humans and wild animals get along?

  Author: Zhang Wenjuan (Senior Director of China Ecological Civilization Research and Promotion Association)

  The severity and complexity of the COVID-19 epidemic far exceeded people’s expectations. Today, the host or intermediate host in novel coronavirus is considered to be related to wild animals such as bats or pangolins. Throughout the world’s major epidemics in human history, almost every time is related to wild animals, which further forces us to reflect: how do humans and wild animals coexist and coexist?

  On November 16, 2019, at the Daqinghe Bird Rescue Station of Laoting County Wildlife Conservation Association in Hebei Province, the staff released an ordinary horseshoe crab. Xinhua news agency

  Wild hosts of deadly viruses or bacteria.

  The struggle between human beings and viruses or pathogenic bacteria has never stopped.

  Plague is caused by a microorganism named Yersinia pestis. Besides mice, there are other common rodents and wild carnivores as the host animals. Besides these animals, there are fleas parasitic on them. The first recorded plague pandemic in human history occurred in the 6th century A.D., originated in the Middle East, and spread to North Africa and Europe through Egypt, killing nearly 100 million people. At that time, the total population of the world was only over 200 million. The second plague began in the mid-14th century, and in 300 years, the European continent lost 1/3 to 1/2 of its population. The third plague pandemic began in the second half of the 19th century, and it first broke out in Yunnan, China, and then broke out in South China, North China, Northeast China and other countries such as Europe, Asia and Africa.

  Macaque Guangming Daily reporter living in Qianling Mountain Park, Guiyang City Xu Tanshe/Guangming Picture

  In 1976, a terrible disease broke out in Sudan and Zaire in West Africa, and the patient died quickly after high fever and systemic bleeding. Scientists found a new virus in the body of the deceased and named it after Ebola, a beautiful river in West Africa. This is a typical zoonotic infectious disease, and mammals such as humans, apes, porcupines, antelopes, monkeys and fruit bats may be infected. Scientific research suggests that fruit bats may be the natural reservoir of Ebola virus.

  Marburg virus is a close relative of Ebola virus. The virus first appeared in Germany in 1967, 31 people were infected and 7 people died. The source of infection was traced back to a group of African green monkeys from Uganda. The largest Marburg virus epidemic on record occurred in Angola, Africa in 2005, when the mortality rate was as high as 90%. At present, there are 12 outbreaks of Marburg virus, the most recent of which was in Uganda in 2017.

  SARS, a disaster that is still fresh in our memory, has a mortality rate of 11%. SARS coronavirus is the same as novel coronavirus coronavirus. At first, some people thought civet cats were the host of the virus, but after more than ten years of follow-up research, scientists detected the gene residue of SARS virus in the body of Jutoubat, and thought that Jutoubat might be the real culprit of SARS virus.

  For thousands of years, as the oldest enemy of human beings, viruses have been coexisting with human beings. Viruses are always threatening human beings, and human beings are constantly developing medicine to conquer viruses. Nowadays, plague has become less attractive, mainly due to the advent of plague vaccine in 1908 and the development of modern biomedicine. However, new viruses are still emerging one after another, and some old viruses are also making a comeback in a mutated way. We have to be on our guard at all times.

  Pandora’s Box was opened.

  The deadly virus or bacteria infected by human beings are actually permanent residents of other species. For example, bats carry a variety of viruses, including hundreds of coronaviruses; Wild snakes carry a variety of parasites in the body. If humans are infected, they can cause peritonitis, septicemia, pericarditis, iriditis and other diseases. In severe cases, they will damage many organs and even endanger their lives. Raccoon is the natural host of rabies virus, and many parasites carried in it can cause damage to human intestines and stomach. The wild groundhog, which became popular on the Internet because of the "expression pack", also carries Yersinia pestis and other germs that can cause intestinal, liver and brain damage.

  Generally speaking, without human intervention, these viruses or bacteria only exist in wild animals. One of the unique qualities of bats is that they are more tolerant of viruses than other mammals. As the only mammal that can fly, bats have a special immune system. In this regard, there is a popular expression on the Internet: "Bats have a high fever of 40 degrees for a long time, and they have sealed the virus for thousands of years by themselves, staying up all night and trying to play a lonely Pandora’s box, so that the virus can coexist peacefully with itself."

  However, as human beings at the top of the biological chain, they sometimes do the opposite, attacking and hunting wild animals for their own selfish desires, and causing many innocent creatures to suffer.

  In some people’s eyes, bats, mice, snakes, pangolins, monkeys and other wild animals are all edible and delicious. Wild animals such as Chinese sturgeon, civet cats and pangolins are on the verge of extinction in many areas due to human overfishing and eating. The populations of giant salamander (giant salamander), wild sea cucumber, wild frogs, wild birds, muntjac, musk deer, gecko and other species have declined sharply.

  Human’s aggression against animals is not only manifested as appetite. In the documentary "The Secret of the Billionaire’s Wardrobe", there is a pair of shoes, only ten pairs are sold worldwide, and the valuation is 20,000 US dollars. The special feature of this pair of shoes is that they are made from the skins of nine kinds of animals, except ostrich skin, crocodile skin, snake skin, and even lizard skin and elephant skin. Luxury brand Hermes has a white platinum bag of Himalayan crocodile, and its flawless leather is actually peeled off from the crocodile.

  In addition, in the process of rapid industrialization and urbanization, forests are cut down, wetlands are squeezed out, and the habitats of wild animals are artificially occupied and separated … … Human activities increase the probability and speed of viruses or pathogenic bacteria in wild animals spreading to human bodies, especially in cities with high population density, which are more prone to epidemic diseases.

  It can be seen that we humans have crossed the border of peaceful coexistence with wild animals, destroyed the original balance of nature, and opened the Pandora’s Box for the spread of epidemics, so that viruses or pathogenic bacteria that originally lived in a closed loop can invade the human body, and constantly mutate and recombine, weaving new strains of viruses or bacteria with stronger toxicity and tolerance, which will inevitably give human beings a painful lesson.

  不打扰,就是最好的相处方式

  人类和自然界的关系比我们想象的要复杂得多。任何野生动物,无论是濒危的还是常见的,在生态系统中都有独特的功能和定位,其他物种无法取代。因此,要从源头上预防新发传染病,我们能做的,就是不打扰——这也是人类与野生动物相处的最好方式。

  不打扰的前提,是我们必须学会敬畏自然。中华文明历来强调“天人合一”的自然观,道家崇尚“道法自然”“清静无为”,孔子提倡“钓而不网,弋不射宿”。如今,我国的经济社会发展进入到一个全新的历史阶段,随着习近平生态文明思想的形成、发展与成功实践,我们必须承认自然的主体价值,敬畏自然,敬畏生命。

  不打扰的内涵,是我们必须学会和谐共生。杜绝不合理的野生动物消费只是最基本的要求,同时还要减少、杜绝对野生动物栖息地的侵扰。在很多人看来,山里没有了野生动物,山还是原来的山。而从生态学的角度看,没有了野生动物,山已经不是原来的山了。一些野生动物的相继灭绝,意味着地球生态系统被破坏,随后,各种自然灾害就会接踵而来。

  The principle of not disturbing is to keep a scientific and reasonable distance. Just when novel coronavirus was raging, wildlife management stations in some places drove away wintering bats on a large scale; In some places, the dogs in the whole village have been killed, and the number of stray cats and dogs in the city has increased in an instant … … It is our human fault to simply and rudely transfer the blame to other animals. From a painful experience, we should think deeply: what kind of distance should we keep between human beings and wild animals? Wild animals grow freely in their own territory. If it is not human intrusion, how can viruses or pathogenic bacteria invade and endanger human health and even life?

  The root of not disturbing is to establish a correct value concept. With the continuous expansion of human greed and the increasing ability to capture nature, when what is claimed exceeds the output of nature, the ecological balance will be broken and human beings will face the crisis of losing their survival safety. The rapid development of industrial civilization for hundreds of years has degraded the earth’s biosphere to the brink of collapse. We must establish correct values, take the idea of ecological civilization as the guide, accelerate the formation of green production methods and lifestyles, consciously protect wild animals, maintain ecological balance, and realize friendly symbiosis and harmonious coexistence between human beings and wild animals.

"Post-90s" wildlife photographer Chu Wenwen: Their real destination is nature.

Nature is selfless, and she shows everything to human beings unabashedly. On April 22nd, Chu Wenwen, a wildlife photographer born after 1990s, and Wang Yuheng, a water brother, visited Sisyphus Bookstore with their new book "Chu Tong: My Wild Animal Friends and I" and accepted an exclusive interview with a reporter from The Paper.

"The real situation is even more cruel than in the movie."
Chu Wenwen, who was born in Altay, is 25 years old. Because of an animal protection scientist’s father, she was taken to the wild at the age of 2; At the age of 7, I began to pack my bags, climb mountains and mountains, cross rivers and wear forests; When I was in my teens, I went to the disaster relief with the team, carrying frozen wild animals all the way in the snow. While other children were busy reciting ancient poems, Chu Wenwen tried hard to remember the names of each plant on the plains of Karamay.
At the age of 7, my father gave Chu Wenwen her first camera and took her to take the first photo of wild animals, which was also an important page in the history of wildlife protection in China-the wild horse of Platts in 2001. From then on, Wenwen often walked in the wild with her camera. At the age of 23, she and her partner also set up the Pupil’s Beginning Nature Image Studio and developed it into Pupil’s Beginning Nature Conservation Association.

At the beginning of the pupil, the Nature Conservation Association has a fixed team of about 10 people. The team based in Altay includes rangers who monitor and rescue wild animals and professional video teams who shoot wild animals. "We are not only doing imaging now, but also doing nature education and endangered species protection."
"I have been telling my team an idea. Whether the film is good or not is not the most important thing. The bottom line and principle you have to respect is to ensure that the animal’s body and mind can’t be hurt. You have to keep it in a complete and normal state, so that what you shoot is a photographic work." Chu Wenwen told The Paper that there are too many pictures similar to "a bird standing on a straw" in the photography circle.
In the story of Wulin owl in Inner Mongolia, Chu Wenwen mentioned that some bird-patting grandfathers did whatever it took to get an ideal picture. Two of them got the GPS positioning point of Wulin owl’s nest privately and went straight to the owl’s nest without saying hello. They wanted to take pictures of a blackbird flying, so they tried their best to drive away a blackbird resting in its nest, and even threw branches, plastic bags and stones at it. One of the stones also hit the owl’s eyes, and finally the owl flew away with a moan.
What happened to this black owl later? At the beginning, Wenwen heard that a friend found it in a forest far away-although one eye had stopped bleeding, the broken wound was visible, and the eyeball could not be seen, and it was obviously blind.
"When shooting wild animals, you can’t force them to look like you want. You should give them more time and patience, waiting for them to show the most harmonious side in nature, not those things that attract people’s attention."
"These photos of Wenwen that everyone saw, for a moment, she may have stayed in water or even ice for more than ten days." At the event site, Wang Yuheng specifically mentioned Chu Wenwen’s father, the animal protection scientist Chu Hongjun. "Have you seen Hoh Xil? Many real situations are even more cruel than in movies. To protect a protected area, we must struggle with many aspects. Mr. Chu Hongjun is a particularly respectable person. "

"Any part that is peeled off is just blood-stained pain."
The stories behind those photos written by Chu Wenwen are warm-hearted and shocking. What she lets people see is not only the brilliance of nature, but also the scars left by nature after being hurt by human beings.
For example, because of eating "breath-holding pills" (a poison invented by a dog dealer in China) by mistake, the big wolf in Inner Mongolia fell in the snow ten centimeters thick, and his claws and toenails were covered with blood scabs. For example, because it is to be made into "chicken wine", Hainan brown-winged Jay can only struggle in the hunter’s bag.
It takes at least 30 such lovely minks to make a mink coat-a painful number.

Maybe someone will say, doesn’t that person always eat fish and meat? In response to this, Wen Wen responded: "In order to survive, human beings need enough food sources, so they are already raising animals. But domestic animals can already satisfy their food and clothing needs, so why should they consume wild animals? Domestic animals are far away from the native land and can multiply indefinitely, and their survival will not be endangered. Wild animals are different. "
At first, Wenwen felt that, what’s more, the "consumption" of wild animals by human beings is also dangerous. "Parasites on wild animals, except in the digestive tract, will also be under the skin, and then you can see the worms, but you can’t see the eggs, and it can’t be killed by high temperature. The so-called medicated wine and medicated diet have no scientific basis, but the idea of always playing wild animals is actually harmful to people’s health. "
As for some places, people believe that spike, wolf’s mustache and wolf’s skin can ward off evil spirits. At first, Wenwen thought it was nonsense.
"In fact, those are only a small part of the body. The real soul of the wolf has disappeared from the moment it died. How can these two bones protect you?" Chu Wenwen said, "once any wild animal loses its integrity, then any part that is stripped off is just a pain covered with blood, which has no meaning."

"Humans and wild animals have the possibility of coexistence."
According to the latest data, there are 162 Mengxin beaver families in China, with an estimated population of 500. The above figures represent Mengxin beavers in Altay, Xinjiang, and even in China-less than the national treasure panda.
Chu Wenwen said that at present, the beaver population is stable, and more shrub willows are needed to further grow. In addition to beavers, cattle, sheep, camels and other domestic animals in the valley wetlands also eat shrub willows. So, is it possible for humans and wild animals to coexist?
Beaver is in the Ulungu River Valley, the only hometown in China. The beginning of photography
"I think there is." Chu Wenwen told reporters in The Paper that this is exactly what they are helping the local government to explore. Because the shrub willow is the main food for the beaver in Mengxin, their team wants to solve the food shortage problem of the beaver in Mengxin by replanting the shrub willow, so they have a "beaver canteen" public welfare project. Through the joint efforts of caring people, 50,000 shrubbery willows provided by the local forestry department were planted near about 10 beaver families in Mengxin to provide enough food for beavers.
"The place where we want to plant trees is the pasture of herders. Therefore, the project launched this year is that we will distribute saplings to herders, let herders plant them, and we will give subsidies. Herdsmen can choose to plant or choose not to plant. "
Chu Wenwen told The Paper that this subsidy involves two inspections. The first inspection was in autumn to see if the cattle and sheep raised by herders had eaten the trees planted in spring and summer. The second acceptance was when we went to plant trees in the following spring. "If you can guarantee that the tree is still there these two times, I will send you all the subsidies."
"This is tantamount to giving herders a choice-choosing to plant this tree will not let cattle and sheep go in to eat, and the subsidies they get are enough for herders to buy grass for cattle and sheep to eat. Or herders don’t want this subsidy and let their own cattle and sheep eat it. In short, there are many ways to guide positively. "
For another example, at the beginning of this year, Wenwen and her team will do a nature education project, and they will also take many children to the wild and really participate in wildlife protection. "In this process, we will let them eat and live in herders’ homes, which will also increase the income of herders and let them know that wild animals can bring them real benefits in this place. Because sometimes herders are not wrong, after all, they have lived in this place for generations, and most people can still communicate, which is very kind. "
Chu Wenwen said: "You let them get something, and they are willing to pay. It is more reliable to let him spontaneously have the awareness of protecting wild animals through this method. "
That’s how beavers build dams. The beginning of photography
"You don’t know if the next person who comes into contact with it has good intentions."
When it comes to the coexistence of human beings and wild animals, many people will think of the animated film "How to Train Your Dragon"-Vikings live with dragons, and people can provide food, accommodation and even companionship for dragons.
"But this is not the case." Chu Wenwen said that for wild animals, the real destination is nature. "What you think is’ good for it’ is not really good for it."
"In my eyes, the animals in zoos and wildlife parks are already domestic animals, because they can never go back (to nature)." Chu Wenwen told The Paper that under normal circumstances, they don’t want wild animals to contact people. "Because you don’t know whether the next person who comes into contact with it has good intentions."
But there are always some "abnormal situations", such as what should I do if I meet an injured wild animal? Chu Wenwen said: "Wild animals are injured, so don’t raise them yourself, but hand them over to the right institutions. For wild animals, reproduction and survival are the most important, rather than staying with their parents all the time. Even if you do get it back, the fetters will have adverse effects. Therefore, we will avoid too much contact with them during the rescue process. "
In Altay, Chu Wenwen is known as the "chairman of the Wildlife Disabled Persons’ Federation" because she has saved many "orphans of nature", such as the white-shouldered sculpture with broken wings because of bumping into the barbed wire fence of herders, the flamingo without half a flipper and the jerboa with amputated limbs. Chu Wenwen said with emotion: "The best hope to save them is to let them eventually return to nature."
At the event site, a student reader asked, "What can college students do for wildlife protection?" Wang Yuheng responded that everyone can actually do it. At present, there are also good protection organizations, but it is a bit mixed. "Many students don’t lack knowledge, what they lack is judgment. Sometimes our kindness will be taken advantage of. The most terrible thing is that once they are found to be used, some people may never want to do good again. "
Wang Yuheng donated all the royalties of "First Pupil" to "Beaver Canteen". At the scene, readers also asked questions about stray cats and dogs. Wang Hao responded: "For stray cats and dogs, I personally suggest not to feed them. Either take it home or send it back to the professional center after sterilization. If you want to choose an animal, it’s like choosing an object. Throughout his life. " Photography Huang mingrui

How to solve the problem of foot sand after playing on the beach? Xiamen seaside shower raiders attack

[News Page-Taihai Net]

  ■ A footbath is set up near the beach in the waters around the East China Sea, which is convenient for citizens and tourists to wash off the sand on their feet after playing.

  ■ Foot bath pool near Haiyuntai.

  ■ Foot-washing pool in front of public toilets in Binhai Romantic Line.

  ■ The footbath beside Huangcuo Beach.

  According to the Xiamen Evening News, the most annoying thing about going to the seaside is that you are covered with gravel but have nowhere to wash. Two years ago, the reporter visited many beaches in our city, and found that some of them had shower places, while others did not. Recently, the reporter visited again and found many changes. I will sort them out in detail today to provide you with service reference.

  Baicheng sandy beach

  Public toilets are hard to find.

  Paid shower advertisements can be seen everywhere.

  Recently, the reporter came to Baicheng Beach, which has convenient transportation and good sunset scenery, and has always been one of the attractions that many tourists must punch in. On the way from the parking lot of Hulishan to the beach, billboards of "washing feet and taking a shower" can be seen everywhere, which are basically clearly marked: washing feet once in 2 yuan and bathing in 10 yuan. The reporter observed that these operators basically pulled out a water pipe and opened their business to provide services. A service point near the beach, foot washing business is very hot, and it also sells drinks business.

  There is a public toilet between Baicheng Beach and Hulishan Fort, but it is hard to find. You need to go through the small door and walk through multiple steps. You can only find it after passing through several paid shower points. Only a very small sign is seen along the way, indicating that the public toilet needs to go 30 meters ahead. The public toilet is adjacent to Hulishan Battery Bus Station, with the words Tourist Toilet in Hulishan Battery Scenic Area written on the side. It is open to the public from 7: 00 am to 7: 00 pm. In previous years, when reporters came here for an interview, there were three hand-washing pools and two foot-washing pools outside the door. This time, I found that the foot-washing pools and hand-washing pools were gone and replaced by several pots of green plants.

  When the reporter arrived, it was 7: 02 pm. At this time, the public toilet was closed, and several tourists at the door seemed very helpless. Mr. Zheng, a tourist, said: "The setting of this public toilet is too unreasonable. It took me a long time to find it, but it was closed after I found it. I just wanted to wash my hands. Isn’t this driving people to the business?" Ms. He, a tourist, said, "I’ve been holding back for a long time, but it’s such a situation that I can’t hold back."

  Mr. Li, a citizen, lives nearby. He said that there were indeed several footbath pools with unlimited time in the past, but people often come here to take a bath naked at night, which is really unsightly. In addition, some people carry buckets to steal water, which may be because of this. It was demolished. "But managers can’t dismantle things at once, and should consider the actual use needs of citizens and tourists. It should be changed to a managed public toilet, and the service should be humanized. "

  Yefengzhai area

  Easy to wash, there is a public toilet every few hundred meters.

  Go along the road around the island, and you can see the public toilet sign indicating the distance on the roadside every walk. Generally, there is a public toilet every five or six hundred meters. In some areas where tourists are concentrated, such as Yefengzhai, there are two public toilets within 200 meters. Every public toilet is kept clean and maintained by the administrator, and there are free footbath pools at the door, ranging from 4 faucets to more than 10 faucets. The reporter turned on one of the faucets at random and found that they all worked normally, and the water was quite large, which could easily wash away the sediment on the body.

  Mr. Li’s family is from Longyan. They are very happy while washing the sand and watching the scenery by the sea. Mr. Li said: "Going out to play is to choose a place with complete infrastructure, especially go on road trip, where parking is convenient and facilities are complete, and playing is really enjoyable."

  Next to the public toilet of Yefengzhai Ocean Science Park, there is also a privately contracted shower equipment. The reporter saw that there were five independent shower rooms in the shower room, equipped with water heaters, air conditioners and other equipment. Ms. Chen, the administrator, said: "The price of washing is 10 yuan, an adult and a child in 15 yuan. People often come here to take a shower after swimming on holidays."

  Wuyuanwan beach

  Demand exceeds supply. Tourists huddle in front of the sink.

  There are several public toilets around Wuyuan Bay Beach. The reporter found that, like two or three years ago, these public toilets were still not equipped with flushing equipment, and some green belt water pipes that had been used by tourists for flushing were also blocked.

  The public toilet B064 is the closest to the beach, between the beach and the parking lot, between the footbridge and the bus stop, with a superior geographical position, and there are many citizens and tourists coming in and out. There is not much space in this public toilet, and there is only a sink. In order to use water, tourists huddle together. There is a sign standing beside it, which says: Please don’t wash your feet in the sink. Someone turned a blind eye and still put his feet in the sink to wash. Some people are more gentle and use mineral water bottles to catch water and wash their feet, but the ground is covered with sand and water.

  Mr. Chen, a citizen, often exercises nearby. He said that this public toilet has a good location and receives hundreds of people almost every day. It is estimated that there are thousands of people on weekends. "Some people even carry their children to the table for cleaning, and the sediment rushes into the pool, which is easy to cause blockage, and the ground is often dirty."

  Master Wang, the administrator, said: "Even if you keep mopping the floor, you can’t keep up with the speed of dirt. I hope to set up a foot bath as soon as possible, otherwise this situation will be difficult to improve. "

  Binhai romantic line

  Well-equipped, washing feet, showering and changing clothes are not a problem

  The coastal romantic line around the East China Sea has been popular among citizens and tourists in recent years. Walking all the way along the seaside, the reporter found that you can find a public toilet every few hundred meters here. Some public toilets use gender-free toilet seats, some are single-family rooms, and the design is quite innovative. Some toilets are also equipped with spraying equipment. Because of the large area of a single room, it is not a problem to simply shower and change clothes. There are foot-washing pools and hand-washing pools outside the toilet, so visitors can get what they need.

  Mr. Wu, a citizen, said: "The facilities of Binhai Romantic Line are complete, but there is still a lack of washing facilities at the seaside from Jimei Qiaotou to Langhua Gate of Romantic Line, hoping to increase the construction."

  Rainbow Beach on the Romantic Line of Binhai is one of the popular places to visit. When the reporter came here in the evening, the beach was full of people playing with the sea. The reporter noticed that in this area, in addition to the public toilets, there is a foot bath pool. In addition, there is a foot bath pool every two or three hundred meters between the two public toilets, and there is also a direct water dispenser next to the foot bath pool. According to the reporter’s observation, the foot bath pool and the public toilet cooperate with each other, which relieves the dense flow of people on the beach and reduces the pressure on the public toilet.

  [Reminder]

  Orderly queuing and civilized flushing

  The administrator of Wuyuanwan shower facilities told the reporter that the quality of citizens and tourists who use washing equipment has improved a lot compared with the past, and some people are not very civilized. It is hoped that citizens and tourists will be able to do civilized washing and orderly queuing when using washing facilities; Turn off the faucet in time after use to reduce the waste of water resources; Turn down the water flow to avoid splashing on others; Take good care of the facilities.

After the peak of mycoplasma pneumonia in children, adults started again? Special reminder from experts

At the specialist clinic of respiratory and critical care medicine in Shanghai Tenth People’s Hospital, Aunt Zheng, who is over 60 years old, just walked for a while, her face turned slightly red and she was a little wheezing. "I came back from a trip a few days ago and started to have a fever and cough." Three days ago, she went to the emergency room and was diagnosed with mycoplasma pneumonia.
In the outpatient department of the hospital, there are still many patients whose families have been "recruited", with fever and cough, and in serious cases, they have been hospitalized because of pneumonia. After the peak of mycoplasma pneumonia in children, adults also started?
Song Xiaolian, chief physician of the Department of Respiratory and Critical Care Medicine of Shanghai Tenth Hospital, said that the infection situation of adults and children is basically synchronous, and the data of both of them have declined slightly at present. The temperature has plummeted these days, so keep warm and beware of a possible new round of respiratory diseases.
Elderly patients have fever, cough and pneumonia after returning from tourism.
On November 14th, an "old patient" came into Song Xiaolian’s expert clinic. Three days ago, Aunt Zheng went to the emergency room because of fever and cough. The examination showed that it was mycoplasma pneumoniae infection, which caused lobular pneumonia and asthma.
After two or three days of infusion treatment, her fever has gone down, but the symptoms of cough and asthma have not been effectively alleviated. Worried about the aggravation of asthma, she quickly hung up the expert clinic she had seen before.
Aunt Zheng had asthma since she was a child. She wanted to travel, but she was afraid of asthma attack. She never dared to leave Shanghai. Seven or eight years ago, after minimally invasive interventional surgery under bronchoscope, her asthma has been well controlled and her overall physical quality has been greatly improved. So she often goes out to visit great rivers and mountains and has not been hospitalized for asthma for several years.
Some time ago, she went out for another trip, but she didn’t expect to be "recruited" when she came back. At first, I had a slight fever, and then I kept coughing, and I even gasped when I walked a little faster. After a detailed examination by the doctor, she was hospitalized for a period of time.
Among the patients who came to see a doctor in the near future, many families have been "recruited" and found to be mycoplasma pneumonia after examination.
In the outpatient clinic, as soon as Ms. Liu came in, she told the doctor, "My old man and children coughed and had a fever a few days ago, and they just happened, so I started again."
Song Xiaolian introduced that, generally speaking, Mycoplasma pneumoniae infection is not as severe as the systemic symptoms of influenza, and the symptoms of upper respiratory tract are not as obvious as the common cold, especially cough and sore throat. In the early stage, it is irritating dry cough, and in the later stage, it will appear white sticky phlegm, which will develop into mycoplasma pneumonia in severe cases, especially for the elderly and children who have difficulty in expectoration, and it is easy to cause lobar pneumonia due to phlegm embolism blocking the airway.
After the peak of mycoplasma pneumonia in children, adults started again?
Not long ago, the topic of "mycoplasma pneumonia in children" frequently appeared in hot search. Affected by mycoplasma pneumoniae, influenza virus, adenovirus and other common pathogens in autumn and winter, in the past two months, the pediatrics of various children’s specialized hospitals and general hospitals in Shencheng continued to explode, especially children with mycoplasma pneumonia occupied more than 80% of the beds in the children’s respiratory ward.
Recently, the number of fever clinics and emergency departments in major children’s specialized hospitals in Shanghai began to decline. The number of fever clinics and emergency departments in Shanghai Children’s Medical Center affiliated to Shanghai Jiaotong University School of Medicine has dropped by 40% compared with the peak at the beginning of the month.
After the peak of mycoplasma pneumonia in children, the concern about adult’s "recruitment" has been increasing. Have adults also begun to enter the peak of infection?
Song Xiaolian said that in fact, the infection situation of adults and children is basically synchronized. Many adult patients have children at home. After the children are infected, they are transmitted to other people in the family, and some are infected after going out to play.
"At present, both adults and children have declined slightly. According to the data, when there was no respiratory epidemic, our daily average number of general outpatients was about 180, which was more than 300 at the peak some time ago, and now it is more than 260 after the peak falls. Generally speaking, compared with adults, children have a higher proportion of pneumonia and have more severe symptoms of high fever. Of course, some patients may have negative mycoplasma antigen antibody test, but the symptoms and images are typical and can still be treated empirically. "
Mycoplasma pneumoniae is a very common pathogen of respiratory tract infection, which exists all the year round, with a small fluctuation every few years, and there are also sporadic cases. Like other respiratory diseases, autumn and winter and seasonal weather changes are high season. Recently, in addition to the prominent mycoplasma pneumonia, there are also many patients with influenza and common cold in outpatient and emergency departments.
Beware of the new peak of respiratory diseases after the sudden drop of temperature.
These days, the temperature in Shencheng has plummeted, will there be a new round of peak medical treatment? According to Song Xiaolian’s experience, it is indeed possible to see a new peak of respiratory diseases.
Under normal circumstances, there are not many patients who come to see a doctor when the temperature drops, but the number of patients who come to see a doctor after a week of cooling will increase significantly. However, the weather forecast shows that the temperature in Shencheng will increase later this week, and the situation will be relatively better.
"It is expected that patients who come to see a doctor later will have mycoplasma pneumoniae infection, flu, common cold, etc., and may also be complicated with infection, so keep warm when cooling down and don’t catch cold. For the elderly, especially those with chronic bronchitis, asthma or bronchiectasis, cooling often leads to sudden aggravation of diseases, and even respiratory failure in severe cases. Therefore, we don’t advocate that the elderly go out to exercise early in the winter. We suggest going out after eight or nine in the morning. It’s too cold in the morning. If there is air pollution, it is recommended to switch to indoor exercise, and you can do aerobic exercise, breathing exercises, and playing Tai Ji Chuan. "
How to prevent the high-incidence season? Song Xiaolian introduced that Mycoplasma pneumoniae is mainly transmitted by droplets, so wear a mask, wash your hands frequently, and ventilate frequently. Don’t go to crowded places, and don’t have close contact with patients with respiratory diseases to enhance their resistance and keep warm. At present, there is no vaccine against mycoplasma, but other respiratory diseases are also high in autumn and winter. It is recommended to vaccinate against swine flu and pneumonia vaccine.
If you are accidentally "recruited", there is no need to panic. She especially reminded that mycoplasma infection is a self-limited disease. For adults with good resistance, take a good rest, even if they are not treated, they will recover after a while. People with poor immunity and severe symptoms should be treated in time.
It is important to pay special attention to that if people are allergic diseases, such as allergies, asthma, etc., mycoplasma pneumoniae infection is easy to induce intractable cough, so it is necessary to see a doctor in time. In addition, the symptoms of pneumonia in the elderly are often atypical, but the more silent they are, the more serious they are. If the elderly have drowsiness, listlessness, or complications, they should see a doctor in time. (Note: All patients in the text are pseudonyms)
