The Biden administration imposed tariffs on imported goods from China, and the American business community repeatedly expressed dissatisfaction.

On the 14th, the United States released the results of the four-year review of China’s imposition of tariff 301, announcing that on the basis of the original tariff 301, it would further impose tariffs on electric vehicles, lithium batteries, photovoltaic cells and other products imported from China.

After the news came out, many business people and business groups in the United States expressed their dissatisfaction.

In a statement to CBN, u.s.-china business council, a group of 270 American companies doing business in China, expressed disappointment with the results of the four-year Section 301 investigation announced by the Office of the US Trade Representative (USTR).

USCBC said: "We are disappointed with this result, because maintaining the previous tariffs (without lowering them) and imposing additional tariffs will eventually make it more difficult for American companies to compete at home and abroad. This will lead to fewer jobs in the United States. In the context of continued inflationary pressures, this will also raise the US consumer price index. "

Earlier, China’s Foreign Ministry spokesperson Wang Wenbin said at a regular press conference on the 15th that according to Moody’s company’s calculation, American consumers bear 92% of the cost of levying tariffs on China, and American families increase their expenses by $1,300 a year.

Liu Bin, a researcher at university of international business and economics School of Government Administration and China World Trade Organization Research Institute, said in an interview with China Business News that (compared with Trump’s tariffs on China), we can see that the industries and products subject to tariff increase are relatively concentrated, and the tariff collection quota has been greatly adjusted. For emerging industries, especially new energy vehicles, the United States has a strong intention to restrict or restrict development.

American consumers pay the bill?

On 14th, KenGriffin, American billionaire and founder of Citadel, said at a forum in Qatar: "Imposing high tariffs on China electric vehicles with low price and high quality, which are beneficial to American consumers, is another manifestation of the discontinuity of Biden’s economic strategy."

The National Retail Federation (NRF) is also "very disappointed" with the Biden administration’s move, and said that "as consumers continue to fight inflation, the last thing the (US) government should do is to impose additional taxes on imported products, which will be paid by American importers and ultimately American consumers".

Recently, Goldman Sachs said in a report that "tariffs in 2018-2019 have significantly increased consumer prices" and that these price increases were "almost entirely borne by American enterprises and families", not China exporters.

Goldman Sachs estimates that every one percentage point increase in the effective tariff rate will directly reduce the gross domestic product (GDP) of the United States by 0.03%, increase consumer prices by 0.1% and keep inflation rising for one year.

Sweet, chief American economist at Oxford Economic Research Institute, said that the political significance of tariffs is usually greater than the economic significance.

Sweet said: "Most economists think that tariffs are a bad idea, because tariffs will hinder a country from benefiting from specialization, disrupt the flow of goods and services, and lead to improper allocation of resources. When implementing tariffs, consumers and producers often have to pay higher prices. "

The new york Federal Reserve also found that tariffs in 2018 cost American families $419 a year due to increased tax burden and loss of market efficiency. The researchers estimate that this figure has doubled as other tariffs take effect in 2019.

Economists wrote in a working paper published by the National Bureau of Economic Research in January 2024 that the net economic impact of import tariffs, retaliatory tariffs and agricultural subsidies on American employment and enterprises is "at best ‘ Rinse ’ Look, and it may be a slight negative impact. "

The above-mentioned researchers said in this working paper that trade friction does seem to bring political benefits and strengthen the support of the Republican Party in the heartland of the United States and the communities most affected by tariffs. "Residents in areas protected by tariffs are unlikely to identify themselves as Democrats, and they are more likely to vote for Trump. Therefore, despite the high economic cost of tariff protection, voters seem to have given a strong response. "

American industry demands competition.

Recently, U.S. Treasury Secretary Yellen frequently appeared in the media to explain the tariff increase policy, but during the interview, she also repeatedly faced questions about whether the tariff increase would drive up prices, including "China’s electric cars are cheaper, so if more people (in the United States) buy them, wouldn’t it help solve the climate change problem".

In this regard, Yellen explained that with the accumulation of experience in producing these products by American companies and the development of newly built battery factories in the central and western regions, the price of automobiles will drop.

However, I am afraid that the industry has different views. CarlosTavares, CEO of Stellantis, a global automobile manufacturer, said that raising tariffs would not protect his company. He believes that "the only choice is to continue fighting", so the only way to compete fairly is to reduce costs and provide electric vehicles at more affordable prices.

In fact, there have been many cases before that prove that imposing high tariffs cannot promote the development of domestic enterprises in the United States.

In 2002, the United States imposed tariffs on imported steel and aluminum products. Subsequent studies showed that although this only caused economic losses of about $30 million, it led to an increase in the price of the steel consumption industry in the United States, and led to a sharp decline in employment opportunities in the entire steel industry, especially those small enterprises that did not have market power to influence prices.

In 2009, the United States imposed tariffs on tires imported from China. The Peterson Institute for International Economics found that this move was thought to have saved about 1,200 jobs in the tire manufacturing industry in the United States, but it cost Americans $1.1 billion in the form of rising prices.

A veteran who has been engaged in the import and export industry in the United States for a long time told the First Financial Reporter that in his view, the United States’ practice of adjusting tariffs this time is more posturing than actual impact.

Taking the solar panel products he is very familiar with as an example, he told reporters that before this adjustment, the solar panels imported by the United States from China had been greatly reduced due to anti-dumping duties: most of the solar panels on the American market were imported from Viet Nam or Thailand, and very few were directly imported from China. In fact, since last year, thousands of containers of related enterprises in China have been detained at the American terminal, and related enterprises may have paid millions of dollars in yard fees at the terminal. The current policy of the United States clearly shows that in order to enter the American market, these companies must set up factories in the United States.

However, in view of some cases that have happened, the prospect of setting up factories in the United States is not optimistic. "If the United States does block the import channels from Vietnam, I can’t imagine where American solar panels will be imported. But it seems unrealistic to rely on solar panels produced locally in the United States. " He added that many media in the United States have also questioned this, and they don’t understand why the import of clean energy products from China should be prevented, especially in the context that the US government has been advocating these clean energy technologies.

Cui Fan, a professor in the Department of International Trade of university of international business and economics Institute of International Economics and Trade, also told China Business News that Biden’s government has begun to contain the overseas investment of China Photovoltaic.

He explained that on April 24, the United States began the photovoltaic double-reverse investigation procedure for Vietnam, Cambodia, Malaysia and Thailand. It is expected that the preliminary ruling will be made this year and the final ruling will be made in the middle of next year. At present, the dumping margin of the four countries listed in the application for investigation ranges from 70.35% to 271.45%, which once blocked the photovoltaic exports of the four countries to the United States.

What needs to be noted is that after the United States announced the imposition of tariffs on China, the EU side, which is conducting countervailing investigations on China’s electric vehicles, is more cautious.

In an interview with China Business News, Liu Bin said that the US tariff increase on China may have a demonstration effect on the EU. However, unlike the United States, the trade links between China and Europe are closer, and the EU is more dependent on the China market.

Liu Bin said that at the same time, China’s new energy vehicles have entered the EU market, which has a "first-Mover advantage". Therefore, it is unlikely that the EU will adjust tariffs on a large scale and in a high amount like the United States. However, the EU may stand in a higher position and adjust taxes in the name of environmental protection.

Editor in charge: Zeng Shaolin

The 3-year-old girl was found missing for 15 hours and slept alone by the wild grave for one night.

  A 30-cm-wide road behind the house almost became a permanent pain in parents’ hearts.

  At 6 o’clock in the evening the day before yesterday, a little girl less than 3 years old in Lin ‘an, Hangzhou, took this road, turned and went away … … She may have been attracted by the bamboo shoots that just popped up by the roadside. She walked and watched, and went further and further, plowing roads and loess roads. At last she got lost, which was a mountain she had never been to.

  Fortunately, at 9 o’clock yesterday morning after a whole night, she was found by search and rescue personnel, unhurt and in a normal mood. She was even asleep when she was found.

  Grandparents, mom and dad, and grandma who arrived from Yiwu cried like tears.

  Nearly 1000 people participated in the search and rescue of the little girl, and a large number of them went spontaneously after seeing the news on the Internet. How did a three-year-old girl get lost? How did she come over on a cold night in the mountains?

  7 minutes

  3-year-old girl disappeared

  Li Yue (a pseudonym) arrived at her mother’s house in Luojiwu Natural Village, Langjia Village, Lin ‘an, Hangzhou at noon on March 27th with her daughter Duoduo (a pseudonym) who is less than 3 years old. A few days ago, she made an appointment with her mother to make Qingming Guo (a kind of food) — — Making rice dumplings is a way for every family to live in Tomb-Sweeping Day.

  At 6: 00 pm, villager Jiang Zhongxiao went to work at night shift. When he passed by, he saw Duo Duo playing at the door, with rice husk in his hand.

  "The adults are here, and my mother also urges me to eat early so that I can take my children back early." In pheasant dock village, Li Yue told Qianbao that she went to add a bowl of rice and just ate a few mouthfuls, only to find that many were gone. Hurry out and look for it, there are few places that I often go to.

  At 6: 13 in the evening, she called the police.

  Jiang Zhongxiao saw that there was a difference of 7 minutes between a lot of time and the alarm time.

  Where can a 3-year-old child go in these 7 minutes?

  On the evening of March 27, the news of finding a 4-year-old girl lost in Qingshanhu Street in Lin ‘an was screened in the WeChat circle of friends. Qianjiang evening news APP "Zhejiang 24 Hours" also immediately pushed "4-year-old Lin ‘an girl lost for 6 hours, help turn! Contact Lin ‘an Public Security 61106110》&mdash clues & mdash; — Up to now, this news has been read nearly 450 thousand times.

  Many enthusiastic people rushed to pheasant dock village one after another, and the search team has rapidly increased from dozens to two or three hundred.

  "First, look inside and outside the village, empty houses, ditches beside houses, and other places where children may go." The relevant person in charge of the village Committee of pheasant dock village said that almost all the people in the village, men, women and children, participated, and the police of the local Qingshan police station did not sleep all night.

  Some people are worried about whether the child has suffered a more serious accident. Taking advantage of the night, several people searched separately, and some of them focused on ponds and reservoirs around the village.

  Zhou Yong, director of Qingshan Police Station of Lin ‘an District Public Security Bureau, stayed up all night, and his voice was extremely tired. "I received an alarm at 6: 13 pm on March 27. In fact, the worst plan was made at the beginning. " He said that the worst consequences that children may encounter include being trafficked and being violated.

  After receiving the alarm, the first wave of 15 policemen who searched quickly set off, and the video group also began to analyze and investigate the surveillance videos near the jurisdiction that day.

  At 7 o’clock that night, Zhou Yong reported to the District Public Security Bureau, and the community streets were linked at the same time, and the Criminal Investigation Brigade also rushed to the scene. At 8 o’clock in the evening, more than 40 police officers of Qingshan Police Station were all involved in the search (except the personnel on duty). At 10 o’clock in the evening, two emergency rescue teams in Lin ‘an and Fuyang rushed to the incident site with professional equipment. At 12 o’clock in the evening, search and rescue dogs joined the search team.

  According to the villagers, the total number of people on the scene at that time exceeded 300 (there were more than 1,000 participants before and after), and the carpet search was spread out.

  Get lost on the mountain with seven turns and eight bends

  She slept alone by the wild grave all night.

  Good news came early on March 28th! On the basis of a large number of investigations by the public security department, the emergency rescue commando team first discovered a lot.

  "At 8: 50 in the morning, I saw something moving 70 or 80 meters away. Looking closer, the little girl covered her head with clothes and was sleeping on the grass." The first child was Mr. Miao of Fuyang Xincheng Emergency Rescue Commando. He said that the child’s little feet that moved from time to time caught his attention.

  "I woke her up, and she didn’t cry, so she said she wanted to find her mother. It’s so happy, the child is safe and everything seems to be normal. "

  At noon on March 28, Qianbao reporter saw a lot. She pestered her mother for a hug and almost forgot what happened the night before.

  "Sleeping in one place, there are very big stones and very small bamboo, which can talk." She said to Qianbao reporter with her hand, with a naive face. She said she left by herself, and it got dark when she walked, and then she went to sleep.

  With the encouragement of my mother, I took everyone again — — She came out from home, walked a few meters, turned left on a road only 30 centimeters wide, turned right on a dirt road after 300 meters, and turned right again after 50 meters — — It’s hard to walk, there are puddles and mud, keep walking, walking, walking … …

  The 3-year-old Duo Duo has limited language skills and can’t describe the details accurately, but she still took us to a hillside — — It is about 1 km away from the village where Duoduo’s grandmother lives, and it takes nearly 30 minutes for adults to walk.

  "Look, isn’t there a big stone there? Just sleep here." The place with many fingers is a graveyard, and there are two shoes left by her in the haystack. "It’s so cold."

  "Yes, this pair of shoes is a lot." Mother Li Yue’s eyes are red again. Self-reproach, guilt, the night’s suffering and the luck that finally arrived made her unable to imagine her daughter’s night’s experience, and even more made her speechless.

  A lot of safe return made many people who participated in the search and rescue shed tears.

  Fortunately, the most worrying thing didn’t happen.

  As of press time, the police have not found any suspicious people or cars entering the village, nor have they found any evidence that the girl was controlled. She should have lost herself.

The 2020 Car Emperor Annual Car List was announced! Volvo XC60 won the "Best Safety Model of the Year" award.

   Recently, the list of "Car of the Year Who Know Car Emperor in 2020" was officially released. This annual car list is based on the evaluation results of "Knowing Car Emperor’s Actual Measurement" in 2020, which is different from the evaluation based on the subjective feelings of car editors. Knowing Car Emperor judges by the measured data results, which brings consumers a more objective and real annual car list and provides users with a powerful reference for car purchase.

   It is understood that the "Know Car Emperor’s Actual Measurement" is that the original team of Know Car Emperor selected more than 400 popular models in the market according to the user’s attention to the models, and conducted a unified standard practical test, including data such as "safety", "space", "energy consumption", "performance and handling" that users are most concerned about, and finally formed an objective and reliable evaluation database, and sent users a simple and easy-to-understand "automobile configuration manual".

  Know the car emperor’s annual car announced seven awards, a number of popular models on the list.

   The 2020 annual car list includes seven awards, including the best safety model of the year, the best family car of the year and the best electric car of the year.

   In the test of knowing the car emperor, Volvo XC60 became the first AEB test full score model. Moreover, with its amazing performance in elk, braking and body structure safety, it has become the best safety model of the year.

   Know the car emperor’s best family car of the year, won by Honda Odyssey Rui Hybrid. It has good performance in space, fuel consumption and quality stability. Coupled with a good rate of preservation, it has become an excellent choice for family cars.

   Since 2020, electric vehicles have become the trend of the times, and it has also become the measured object of the original team that understands the car emperor. The results show that Weilai ES6 won the best electric vehicle of the year with its strongest comprehensive strength. No matter in driving quality, sports performance or intelligent safety, it is the most balanced electric vehicle in the electric vehicle industry at present.

   The actual measurement has gone through the unified measurement process, including "static acceleration test", "braking distance test", "Elk test", "Jingang circuit lap speed test" and "fuel consumption test". All models have been repeatedly tested by the same professional racer in the same professional racetrack for more than 100 times. Moreover, they all use equipment and test methods and standards that meet international standards. Taking the Elk test as an example, more than 300 vehicles strictly implement the ISO3888-2 international standard, and each vehicle will be tested for nearly 20 times, constantly approaching the limit posture of the vehicle, so as to fully quantify the safety and handling of the vehicle. In addition, the actual measurement also creatively joined the original project of knowing the car emperor-the lap speed test of Jingang circuit. At the full speed of each car, the measured team who knows the car emperor records its lap speed, straight tail speed, low-speed corner, high-speed corner, etc., so as to effectively grasp the overall mobility of the car. Under the unified and professional measurement of knowing the car emperor, the list data is more objective and reliable.

   In addition to the above three award-winning models, Know Car Emperor also divided the rest of the award list in detail according to the characteristics of the models and the demand for vehicles: McLaren 720S won the Best Performance Car of the Year by virtue of its excellent power and aerodynamic design; Land Rover Defender passed all the test items in the test of Chedi off-road base and won the best off-road vehicle of the year. Tesla MODEL S won the fastest accelerated model of the year with the acceleration of "Tubang Class"; Ford New Transit won the Best Tool Car of the Year for its excellent performance in terms of the maximum volume of the interior space, the width and depth of the trunk opening.

  Dedicated to the professional evaluation of automobiles, bringing valuable content to users.

   After long-term development, China has become the largest automobile production and sales market in the world. However, with the increasing popularity of automobiles, various brand models emerge one after another, and the market information is increasingly huge, which greatly increases the cost and difficulty of consumers’ car purchase decision.

   Compared with developed countries, China’s automobile evaluation system is still in its infancy. Most of the existing evaluation systems lack unified standards, are mixed with subjective factors, and the evaluation results have certain errors. Consumers lack a scientific and professional reference index for car purchase. In this context, as a professional automobile media in China, car owners can learn from foreign experience and integrate their own advantages to provide consumers with more accurate car purchase guidance.

   Knowing the car emperor’s actual measurement not only follows the international professional evaluation process and standards, but also creatively adds original actual measurement items to the China automobile market, so as to create an automobile evaluation system serving China automobile consumers. Relying on the professional testing team, testing site and equipment, Knowing Car Emperor not only forms a measurable and referential standard for China automobile testing, but also forms a more professional and fair automobile selection system, setting a brand-new benchmark for third-party professionals to participate in automobile evaluation.

   Up to now, Master Car has a very comprehensive vehicle evaluation database, and based on standardized venues, professional tools and equipment, and industry-recognized testing methods, it has gradually established a perfect evaluation system for Master Car, including unique active safety evaluation standards, track performance testing standards and off-road ability testing standards. It provides users with reliable, retrievable and comparable vehicle evaluation data products.

   For a long time, the team who knows the contents of Chedi insists on providing users with professional, data-based and most referential documentary evaluation contents based on the needs of users. In order to ensure the authority of evaluation and disassembly contents, the team not only needs to consult experts frequently, but also make up a lot of knowledge of materials science. The 2020 Car of the Year, which was selected this time, provides accurate reference for consumers with car purchase needs by subdividing the award-winning models, so that users can choose models as needed. In addition, there is an original evaluation channel in the station, which can help customers better understand the performance and detailed evaluation data of the vehicle.

   In the future practice, Knowing Car Emperor will continue to lead the new trend of automobile evaluation in China with strict and scientific evaluation procedures and standards, and build a weather vane for the automobile industry. While helping consumers to obtain more convenient and scientific car purchase information, it will also help high-quality car brands stand out in the evaluation and promote the Excellence and healthy development of the automobile industry.

  When the accelerator pedal is released, the kinetic energy recovery system intervenes more smoothly, and there is no obvious dragging feeling. This setting helps to improve the vehicle’s endurance performance. In terms of braking, the brake pedal stroke of the vehicle is slightly longer, especially the driver may feel that the braking force is soft in the first half, especially in the case of emergency braking, the driver needs to anticipate and apply more braking force in advance. In non-emergency braking conditions, when the brake pedal stroke exceeds 1/3, the feedback becomes clear, and the braking force is uniform and linear. In this setting, the driver needs a certain amount of adaptation time.

  The chassis adjustment of the EP008 extended range version is designed to be comfortable but not lose toughness. When passing through bumpy roads or speed bumps, the suspension system can effectively absorb ground vibrations and maintain the stability of the body. At the same time, the vehicle can also maintain good stability at high speeds without fluttering.

  Dongfeng Yipai eπ 008 fully demonstrates the style of both atmosphere and technology in its exterior design. The front face adopts the combination of intelligent star grille and double sapphire headlights, which not only highlights the charm of technology, but also enhances the recognition of the vehicle. The double flying swallow logo inlaid in the middle complements the thick through-type lights, adding a bit of grade and cultural connotation to the whole vehicle.

  The side lines of the eπ 008 are smooth and dynamic, and the straight roof design with C-pillar small windows not only visually lengthens the body length, but also provides a wider view for the third-row passengers, reducing the sense of oppression. The design of the lower waist line adds a touch of agility to the side of the body, and the chrome trim strips running through the front and rear further enhance the luxury of the vehicle. The design of the hidden door handle not only enhances the overall feel of the body, but also effectively reduces the wind resistance coefficient, reaching 0.268Cd.

  The design of the rear part of the car is also full and layered. The decorative lines on both sides of the bumper add a sporty element, and the through taillights complement the characteristic lines of the license plate area to create a more three-dimensional visual effect. The lattice-arranged lamp cavity structure not only echoes the headlights, but also gives the rear of the car a stronger recognition.

Standing Committee: increase policy support such as export tax rebate to promote the steady development of foreign trade.

On April 13th, Li Keqiang, Premier of the State Council of the People’s Republic of China presided over the the State Council executive meeting and decided to further increase policy support such as export tax rebate to promote the steady development of foreign trade.

Export tax rebate is a policy that is inclusive, fair and in line with international rules. The Standing Committee of the National People’s Congress proposed three specific measures.

First, the processing trade enterprises should refund the unrequited tax after implementing the consistent policy of collecting and refunding tax rates for export products, and allow the transferred input tax to offset the value-added tax. Export credit insurance claims are regarded as foreign exchange receipts and tax rebates are applied.

The second is to speed up the progress of tax refund, implement the whole process online, and reduce the processing time of tax refund from an average of 7 working days to 6 working days.

The third is to improve the efficiency of customs clearance for the return of export goods, formulate policies to facilitate cross-border e-commerce, give more convenience to trustworthy enterprises in customs clearance and tax refund, and severely punish fraudulent tax refund.

Zhong Huiyong, associate professor of the School of Finance of Shanghai University of International Business and Economics and deputy director of the Institute of Financial Development, told The Paper that the deduction of value-added tax can avoid the overlap of export tax rebate and value-added tax payment, and reduce the complexity of corporate tax payment. Treating export credit insurance claims as foreign exchange receipts and handling tax rebates can enable enterprises to enjoy the benefits of export tax rebate policy as soon as possible.

"Improve the flexibility of the export tax rebate policy, better reduce the burden on foreign trade enterprises, and enable foreign trade enterprises to tide over difficult times smoothly." Zhong Huiyong said that shortening the time of tax refund will enable foreign trade enterprises to get the dividends of national policies more quickly.

Zhong Huiyong also said that improving the customs clearance efficiency of export goods and the cross-border e-commerce exchange policy can reduce the worries of foreign trade enterprises and better encourage exports. At the same time, we should also avoid foreign trade enterprises and make use of favorable policies to defraud tax rebates. (Reporter Hou Jiacheng)

(Responsible units: District Development and Reform Commission, Fengtai Park Management Committee and District Finance Office)

  Fourth, ease the credit pressure of enterprises

  Take the initiative to accurately connect financial institutions for key enterprises in epidemic prevention and control, coordinate special credit support, and do not lend, keep lending or suppress loans to enterprises that have temporary difficulties in operation but have development prospects due to the epidemic. For enterprises that failed to be included in the special refinancing support scope of the People’s Bank of China during the epidemic period and met the industrial development direction of Fengtai District and made outstanding regional comprehensive contributions, banks in the region are encouraged to provide financial support for them and give a discount of 1.5 percentage points of the loan amount, and the discount amount for a single enterprise does not exceed 1 million yuan. The local government guarantee institutions launched "anti-epidemic loans" products to help small and medium-sized enterprises that are greatly affected by the epidemic to renew their loans and reduce the comprehensive rate by 0.5 percentage points. (Responsible unit: District Finance Office)

  Five, reduce the cost of enterprise property

  Small and medium-sized enterprises that lease the real estate belonging to state-owned enterprises directly under public housing and state-owned enterprises in the area to engage in production and business activities, adhere to business according to government requirements or close down in accordance with epidemic prevention regulations without layoffs or fewer layoffs, will be exempted from February rent; Leased for office space, 50% of the rent in February will be reduced. For renting other business premises, the owner (landlord) is encouraged to reduce or exempt the rent for the tenant, which shall be settled by both parties through consultation. For commercial buildings with outstanding regional comprehensive contributions recognized by the competent department of industry, if rent is reduced or exempted for small and medium-sized enterprises in line with the industrial development direction of Fengtai District, subsidies will be given at 30% of the amount reduced or exempted in February and March, with a maximum of 1 million yuan; Large shopping malls and shopping centers with outstanding regional comprehensive contributions recognized by the commerce department will be subsidized by 30% of the amount of rent reduction and exemption in February and March, with a maximum of 1 million yuan.

Non-genetic inheritance | sunflower art, not just a sunflower fan!

In the long history,

People who have lived here for generations,

Left us with a wide variety,

Unique and precious intangible cultural heritage,

Now,

These traditional cultures and techniques

In the process of inheritance and innovation, new flowers are blooming.

today

Let’s learn together.

National intangible cultural heritage:

Xinhui kuiyi

Xinhui

Since ancient times, it has been rich in Pukui and is known as Kwai Township.

Xinhui people from the Eastern Jin Dynasty

I started planting sunflower as a fan.

palm-leaf fan

Is the representative of Xinhui Kuiyi.

Making a sunflower fan

More than twenty processes are needed.

Planting sunflower, picking sunflower, drying sunflower,

Baking fan, cutting fan, cutting fan, closing fan …

On the coast of the South China Sea, the west bank of the Pearl River and the bank of Yinzhou Lake, there is a famous cultural city with a long history-Xinhui. Xinhui is a famous hometown of overseas Chinese, and it is also known as "Kwai Township" because it is rich in Pukui. Xinhui sunflower art has a long history, and the planting and processing of sunflower trees began in the Eastern Jin Dynasty. After more than a thousand years’ exploration, Xinhui people have integrated knitting, embroidery, painting and printing, making the processing of sunflower art products reach a superb position. In the most prosperous period of sunflower industry, Xinhui has more than 300 sunflower factories and more than 500 varieties of colors, and its products are exported to Europe, America and Southeast Asian countries.

At the beginning of Qing Dynasty, Qu Dajun wrote in "Guangdong Xinyu Pu Kui Fan": "The edge is made of the silk of wild silkworm, embedded with the piece of Bai Lin, the handle is made of the brand of Qinglang, wrapped with the thread of dragon beard and rattan, painted with copper nails, and the painting is gorgeous."

In 1958, Premier Zhou Enlai visited Xinhui and made a special trip to Kwai Art Factory, and spoke highly of Kwai craft products in Xinhui. When Guo Moruo visited Xinhui in 1959, he praised the sunflower fan technology: "The cool world comes from the hands, and it is more skillful than the ghost axe, flying all over the world and overwhelming the west wind." Guan Shanyue, a great master of Lingnan School of Painting, tried to "brand fire painting" for more than 60 times, but because he couldn’t grasp the strength of the soldering iron, he burned the fan every time. Finally, he had to throw a sigh of "branding": What a stunt!

The main products of Xinhui sunflower art include sunflower fan, sunflower basket, sunflower mat, cushion and sunflower coir. Besides, Xinhui sunflower art can also make a painting, a lantern and a screen, which has great plasticity.

▲ Tuyuan Xinhui released

Among them, the craft sunflower fan is the most famous one with pyrography and embroidery, which is one of the four traditional crafts in Guangdong. Fire painting fan is recorded in the records of Daoguang County in Qing Dynasty. Chen Wan, an old painter at the end of Tongzhi in Qing Dynasty, pushed the skill of fire painting fan to the peak. In 1915, a sunflower fan in Xinhui won the gold medal in Panama International Expo. In 1952, it was listed as a special handicraft by the state, and also won the first "Hundred Flowers Award" of China Ministry of Light Industry and other national awards.Xinhui Kuiyi was selected into the national intangible cultural heritage list in 2008.

… …

At home, good news comes one after another!

Abroad, New York ordered 17,000 ventilators from China.

Even Tadpole Jun’s overseas friends said,

His mother insisted on buying him a ventilator on Taobao.

"I am so helpless. If medical ventilators can be bought on Taobao, how can there be such a shortage abroad?"

so

What is the difference between the ventilator in the hospital and the ventilator we usually say? Is it necessary for ordinary people to use medical ventilators? What kinds of medical ventilators are there?

Mom really doesn't have to buy me a ventilator.

Too long to read the version

Rescue breathing equipment can be roughly divided into:

Oxygen therapy equipment, ventilator and artificial lung (ECMO).

They have their own characteristics, and the diseases they aim at are different.

Healthy people, there is absolutely no need to buy it themselves.

Oxygen therapy equipment

When it comes to ventilators, many readers may immediately think of scenes in TV dramas. The attending doctor said, "Come on, the patient is dying." As soon as the voice fell, the nurse hurried to push the oxygen bottle. Oxygen bottles, oxygen bags and various oxygen generators on shopping websites all belong to oxygen therapy equipment.

Oxygen therapy equipment has two functions.

(1) directly provide oxygen for patients.

If we compare the human body to a jar, with one mouth sucking air and one mouth discharging waste gas, then the oxygen concentration in the jar must be kept constant because every cell needs a certain amount of oxygen. However, in some cases, the oxygen concentration in patients will drop. For example, the patient is in a plateau, and the oxygen in the air is insufficient, or the patient suffers from chronic obstructive pulmonary disease, and the trachea and bubbles are diseased, so no matter how hard he tries, he can’t breathe in too much air. What should we do? The answer is to increase the oxygen concentration in the air inlet, that is, to provide patients with higher concentration of oxygen through oxygen therapy equipment.

(2) as an oxygen source

Oxygen therapy equipment can also be connected to a ventilator as a source of oxygen. It can be seen from here that the ventilators mentioned by doctors are not the same as oxygen cylinders and oxygen generators.

Hyperbaric oxygen chamber is a special oxygen therapy equipment. In other words, it is essentially an oxygen cylinder, but it can be as big as a room. The atmospheric pressure inside is usually three times the normal pressure, and accordingly, its oxygen concentration is very high.

There are two common uses of hyperbaric oxygen chamber.

One is to deal with anaerobic bacteria, which are afraid of oxygen; The second is to treat carbon monoxide poisoning. For the human body, hemoglobin is equivalent to a trolley for transporting oxygen, and carbon monoxide can occupy hemoglobin, thus affecting the supply of oxygen. High concentration oxygen must be used to drive away carbon monoxide in order to save the patient’s life.

Because of the high oxygen concentration, hyperbaric oxygen chamber is a very prone to fire. Don’t say that playing with lighters, even static electricity accumulated on chemical fiber clothes may cause accidents. Therefore, if you need to use hyperbaric oxygen chamber treatment, you must strictly follow the guidance of medical staff.

Having said that, one more thing: all oxygen therapy equipment has a specific scope of application. Some sellers say that "regular oxygen inhalation can improve immunity and children’s performance" in order to increase the sales of oxygen generators. In fact, normal people don’t need these at all.

Noninvasive mechanical ventilation

Under normal circumstances, when inhaling, the muscles around the lungs are pulled outward to drive the alveoli to expand; Once the alveoli expand, the pressure inside is small, which can accommodate the gas from the outside. Covid-19, on the one hand, can directly damage alveoli and interfere with the expansion of alveoli, on the other hand, it will attract immune cells, and the fighting between them will inevitably cause inflammation and further aggravate atelectasis.

What should I do in this situation?

The answer is noninvasive mechanical ventilation.

Non-invasive means no wound; Machinery is the use of a ventilator; Ventilation means inhaling oxygen and expelling carbon dioxide. The motor in the noninvasive ventilator can compress oxygen, create pressure, and then, along the breathing mask, enter the patient’s lungs — — Whether the alveoli can expand or not, oxygen is directly injected into them.

Of course, this is just a general principle, which is actually much more complicated. The pressure produced by the ventilator can be positive pressure or negative pressure, which can be generated continuously or provided intermittently, and can be adjusted according to the patient’s situation; There are also many kinds of breathing masks, which can be used only for the nose, or to wrap the mouth, or to wrap the whole face of the patient.

Invasive mechanical ventilation

Pay attention to the news, and you will find that most of the ventilators mentioned recently are invasive ventilators.

The biggest difference between invasive mechanical ventilation and noninvasive mechanical ventilation is whether to establish an airway for patients. Some patients have claustrophobia and can’t accept breathing masks, some patients have facial trauma, which affects the fit of breathing masks, and some patients have a lot of sputum in their trachea, which seriously affects the effect of ventilation. Therefore, the doctor will make an incision in the patient’s trachea, insert a hose into it, and artificially establish a passage for air in and out.

Accordingly, the structure of invasive ventilator is more complicated. For example, an invasive ventilator is equipped with a battery, which can continue to work and care for patients’ lives even if the mains supply is interrupted or the emergency power supply fails in the hospital.

Therefore, the invasive ventilator is usually fully functional and can be used as a noninvasive ventilator in an emergency; Conversely, the non-invasive ventilator cannot be used as an invasive ventilator because of its limited function. This may be why most of the current foreign orders are aimed at invasive ventilators.

In vitro oxygen membrane bonding

In vitro oxygen membrane bonding is the ECMO that is often mentioned in the first two months.

Strictly speaking, it is not a ventilator.

Non-invasive ventilator and invasive ventilator are both helpers of the lung, and assist patients to breathe through masks or tracheal intubation; When ECMO is needed, it doesn’t matter whether the patient can breathe or not, it can take over breathing completely.

When using ECMO, we should first make an incision in the patient’s blood vessel to draw the blood out. Then, ECMO will expel carbon dioxide from it, inject enough oxygen and heat it properly; Finally, the blood with proper temperature and full of oxygen is sent to the patient’s blood circulation through the motor.

In other words, ECMO is equivalent to a weakened version of the time capsule, which can temporarily save the patient’s life. The key is whether doctors can find a solution to the fundamental problem in a limited time.

However, ECMO and ventilator have one thing in common: both need oxygen. During the closing period of Wuhan, many hospitals were short of oxygen because of the surge of patients. Those workers who work overtime to produce oxygen and transport oxygen are also great contributors to the fight against the epidemic.

The domestic epidemic situation has improved recently.

But before the advent of specific drugs and vaccines

Oxygen therapy, noninvasive ventilator, invasive ventilator and ECMO.

Is the most effective way for us to deal with novel coronavirus.

To make good use of them,

Not only need excellent medical staff,

But also the cooperation of manufacturing and transportation.

I hope that over time,

We can master these technologies thoroughly,

Better care for people’s health.

Mom really doesn't have to buy me a ventilator.

magpie

  Magpies can be said to be the most common birds in rural areas of Guanzhong, especially in the countryside near the northern foot of Qinling Mountains, on the big trees in front of and behind people’s houses, and among the branches on the banks of ditches in rural areas. Magpie looks very festive, with a round head, a pointed beak, a fat body, a long tail and feathers in black, white, blue and purple, which can be said to be loved by everyone. What the villagers like best is its chirping sound, which they think is an auspicious sound. "When the magpies chirp, the guests will come", which is a favorite saying in our village.

  I also like magpies for two reasons. First, I have lived in the countryside since I was a child. Magpies are more common and seen, just like my neighbors. When I am familiar with them, I am happy. Second, I think this kind of bird looks good and sounds good, unlike sparrows, which gather in groups in front of people’s eaves all day, chattering, making people upset, and sometimes harming crops and making people hate it. Nor is it like an owl, whose voice is sharp and harsh, such as a sharp instrument crossing a slate.

  In my memory, magpies are the most common in spring and winter, but they don’t seem to be seen much in summer. This may be the reason why the magpie’s whereabouts are not easy to be found in summer. In spring, magpies can often be seen in Yuan Ye, my hometown. They jump in the wheat field one by one, head by head, and look very fun; Or while chirping, slowly fly from tree to tree, and the tail feathers draw a beautiful arc. This season, magpies’ nests are also easier to find, mostly on tall poplars. Walking in the countryside, when I look up, you will see huge magpie nests, crouching peacefully among the treetops of Gao Yang willow trees, as if they were pieces of art.. The sky is pure and blue, not stained with a trace of dust. At this time, there may be wind, and the nest will gently shake with the wind.

  Although it shakes, there is no need to worry that the nest will be blown down by the wind, because magpies are masters of nesting. I have lived in the country for many years, and I have seen many bird nests, such as those of swallows, sparrows and turtledoves … I think they are not as beautiful and strong as those of magpies. Sparrows make a nest out of a mess of grass. Sometimes, they don’t even build such a simple nest, but live directly under the eaves of others or among the trees. Swallows’ nests are exquisite, but they are also built on the beams of other people’s houses, and they like to use old nests, which are neither as big as magpie’s nests nor as beautiful as magpie’s nests. As for the doves’ nests, they are mostly built in the oblique branches of the trunk of a big tree, which is not only sloppy, but also extremely unsafe. When I was a teenager, I saw more than once that the village children climbed the tree to dig out the nest of the turtledove, and the turtledove flew around the tree in shock. Magpies, on the other hand, have no such worries. Their nests are mostly at the top of big trees, and village children can’t climb them. Even if they climbed up, because the branches at the top of the tree were too thin, the children were afraid of breaking the branches and falling to the ground, and did not dare to climb to the top to dig out the magpie nest. What’s more, the villagers also forbid children to climb the tree and dig out the magpie nest. Therefore, it is very natural that magpies are more common in their hometown.

  In spring and summer, magpies are busy building nests, laying eggs and brooding, but in autumn, magpies seem to be more relaxed. This season, the young magpies have grown up, so they don’t need to be fed. There is plenty of food in the field, and they can eat without much effort. The full magpies are singing and playing in the fields, or in the big trees in front of and behind people’s houses. Only in winter, because of the lack of food and the cold weather, they seem sluggish and seem to be less active than in spring, summer and autumn. Magpies seen in winter are mostly foraging.
