Teach children math.

"A cabin is only 6 square meters. If you live in it, how will you decorate it?"

On December 25th, 2023, in the "Research and Practice Class of China Mathematicians Entering the Primary School Classroom" taught by Hua Yinglong, Vice President of Beijing No.2 Experimental Primary School, interesting questions deeply attracted the sixth graders.

The Mathematics Curriculum Standard for Compulsory Education (2022 Edition) points out: "The content design should reflect the application of mathematics in nature and society, show the great mathematicians in the history of mathematics development, especially the famous mathematicians in ancient and modern China, and the role of their mathematical achievements in the development of human civilization, and enhance students’ patriotic feelings and national pride."

It coincides with the 90th anniversary of the birth of Chen Jingrun, a famous mathematician in China. Hua Yinglong can’t help but think about the requirements of the curriculum standard: What kind of collision will happen when the world-famous China mathematician enters the primary school classroom? I want to chase the "brightest" star with my children!

Plant the seeds of curiosity

This class begins with the sharing of reading experience before class. Before class, the students previewed the reportage Goldbach conjecture in advance. In class, the students scrambled to share their feelings.

"Although some people discriminated against him, he didn’t waver in his love for mathematics. He was always calm, and his tolerant spirit was worth learning."

"I want to say to Chen Jingrun that you are really amazing. You were born in a family with no math environment, but you have made such achievements through hard work."

"What impressed me most was that Chen Jingrun studied hard in a 6-square-meter hut despite the difficult conditions."

…………

Students talked about being moved by Chen Jingrun’s spirit of studying and studying, and began to notice the mathematical element of "6 square meters" under the guidance of the teacher.

Hua Yinglong asked, "What kind of math topic do you think you can make up about the 6-square-meter hut?"

"Chen Jingrun’s room is 6 square meters, and their chimneys account for one-sixth of the room. How big is the living area?"

"The room is 6 square meters in total, and a chimney has cut the room into a corner, which is one-sixth of the room area. How big is this corner plus the total room area?"

…………

According to Hua Yinglong’s questions, the students expressed their opinions and collected five different proposition ideas. Hua Yinglong immediately gave his own examples. The students called "simplicity" and "logic", and an ordinary application problem set off a hearty "brainstorming" between teachers and students.

The reading method with "questioning" as the main guidance makes students experience the fun brought by mathematics reading, and guides students to think deeply and be eager to try after thinking.

After mastering more clues, students are more curious about the "6 square meter cabin". Hua Yinglong continued to ask: "What is a 6-square-meter cabin like?" He asked the students to draw a plan of the hut. With the help of students’ work sharing, Hua Yinglong has drawn out one enlightening question after another.

Through mathematics to restore the hut, children’s eyes look at the hut in a variety of ways: some are trapezoidal, some are square, some are marked with the position of the door and bed, and careful students mark the size of each layout …

"Teachers’ teaching design should read the world from a mathematical perspective, which is fascinating," Hua Yinglong said. "As a guide for students’ mathematics learning, we should plant a seed for them, hoping that one day, this seed will blossom a flower of’ everything counts’."

Bold trial and error in exploration

Around the "hut", Hua Yinglong took the students to solve the side length, and the "mathematical flavor" became stronger and stronger. At this time, a quick student confused the area and perimeter, and the students corrected his algorithm one after another. Hua Yinglong praised the student’s quick response and bold speech: "Children, in reading, not only reading, but also thinking. Every mistake is a reminder. We want to thank this classmate for reminding us." There was applause at the scene.

When calculating the side length of the hut, the students encountered a difficult problem-they had not touched the square root and could not continue to calculate.

"Children, we can’t make a square, can we still count?" Hua Yinglong asked. He didn’t impart knowledge beyond the outline, but left time for students to think. When a student tried repeatedly on the toilet paper and found the answer by reverse deduction, Hua Yinglong showed it to everyone with surprise and led them to summarize this valuable thinking process:

"Children, did this classmate try it right just once? No, he also found the answer by mistake, right? " Hua Yinglong once again guides students to correctly look at mistakes in learning. In such a class, students’ frustration tolerance is strong.

"Making mistakes is something everyone has to experience, including teachers." Hua Yinglong said, "We have to tell students that mistakes are often reminders, reminding us to calm down and think: Where is the problem? Why is it wrong? What new possibilities will there be? What new problems can you think about? "

"Where is the 6-square-meter hut and what is it really like?"

In order to give the child an accurate answer, Hua Yinglong shared his "journey to find the truth" after reading relevant books and materials, and went to the address of his former residence "No.88 Zhongguancun Street" in the materials to find out, but found that this was not the location of his mathematics institute. When I went to Fujian, I learned that there was a "Chen Jingrun Experimental Primary School" in the local area. I went there quickly, but I didn’t get the answer … Despite the twists and turns, with the help of Song Li, Chen Jingrun’s nephew, the real hut emerged a little bit: the room was square, and it became a "knife handle" shape after being occupied by the garbage passage. Because the space was narrow, people had to close the door before they could barely stand open …

Hua Yinglong’s exploration process of constantly trying to find a "real cabin" inadvertently set the best example for students.

Give students a bigger world.

"Students, suppose you enter Chen Jingrun’s cabin now, what do you want to say to him?"

As the class draws to a close, Hua Yinglong throws out the last question of this class. As early as in the open space next to the podium, he outlined the spatial structure of the hut with tape, suggesting that students take a walk in the "hut" and feel the living space of 6 square meters.

Some children bluntly said, "I love this mathematician very much, and I hope he will pay attention to his health and live in a big house." Some children felt "the sense of accomplishment gained by tireless knowledge" through repeated thinking, and some children called "Mr. Chen Jingrun is so great that in a difficult environment, he has confirmed the" Goldbach conjecture "that even the great mathematician Euler has not confirmed …

At this point, students’ feelings are not only the absorption after reading, but also the spiritual baptism after the classroom and teachers jointly verify and explore.

The students read the ten characters written by Hua Yinglong on the blackboard in unison-"A humble room grows into a superstar, and hardships make a great man". At that moment, the little boy seemed to have crossed time and space, ignorant and firmly paying tribute to the mathematician.

What can mathematics leave for students?

"A good math reading class is to give students reading energy and spiritual nourishment." Hua Yinglong replied in class, "I always think that education is humanized, which is the highest realm pursued by education." I am a primary school math teacher, but I don’t teach math. I use math to teach children. "

China Education News, January 5, 2024, 9th edition.　

80% of new drug data involved in false supervision has outstanding violations.

　　Since the State Food and Drug Administration started the self-inspection and verification of drug clinical trial data for one year, it has been found that over 80% of the clinical data of new drugs are involved in fraud, and the regulatory links behind them have fallen behind, and the violations of relevant subjects such as pharmaceutical companies, intermediaries and doctors are prominent.

　　Some people in the medical field believe that with the advance of the verification storm, negative arguments such as "too advanced" and "one size fits all" have risen. The state should adhere to zero tolerance for clinical fraud and reverse the medical ecology of bad money expelling good money with stricter supervision.

　　The enterprise intentionally concealed and omitted the records of adverse reactions.

　　The results of the verification of the authenticity and standardization of the data of 1622 drug clinical trial projects to be produced by the Food and Drug Administration caused a shock in the whole industry. Some people in the medical field revealed that with the deepening of self-examination and verification, more problems of untrue and irregular clinical trial data of drugs have been exposed. At present, over 80% of new drug applications have been withdrawn by pharmaceutical companies or rejected by the State Food and Drug Administration.

　　A staff member of the food and drug department said that during the verification, it was found that the clinical trial data of many drugs were incomplete, the analysis data had no differential trajectory, and some data could not be traced back. Other companies deliberately concealed or omitted the adverse reaction records, and revised the test data that failed to meet expectations.

　　"Before this round of self-examination and verification storm, clinical data fraud was an open secret in the industry." The dean of a top-three hospital in the west said that pharmaceutical companies randomly combined old drugs and found several hospitals to do clinical experiments. Of course, they all reported according to the expected results. Finally, the State Food and Drug Administration approved the new drugs. "How can this stew-style drug research and development model ensure the quality and safety of drugs?"

　　"The direct consequence of clinical data fraud is poor efficacy." A person in charge of research and development of a pharmaceutical company in Nanjing said that in a clinical trial, the company replaced the domestic anti-diabetic drug metformin taken by the subjects with the original drug Gehuazhi. Unexpectedly, after taking it for four weeks, the blood sugar of the subjects actually dropped to the level that they could not be enrolled in the group. Previously, the subjects had been taking domestic metformin, but their blood sugar could not be lowered.

　　According to insiders, most domestic generic drugs can’t meet the original research standards. In order to pass the evaluation, it is very common to conceal the discarded data and selectively use the data in clinical experiments. In this regard, the state launched the consistency evaluation of generic drugs’ quality and efficacy this year, requiring all generic drugs approved for marketing before October 1, 2007 to complete the consistency evaluation before the end of 2018, among which clinical effectiveness tests and varieties with special circumstances need to be carried out, and consistency evaluation should be completed before the end of 2021; If it is not completed within the time limit, it will not be registered again.

　　Yu Dechao, Chairman of Cinda Bio-Pharmaceutical, predicted that with the consistent evaluation of generic drugs’ quality and efficacy, more than 50% of the existing generic drugs will be eliminated, and the phenomenon of "bad money driving out good money" in the pharmaceutical field is expected to be initially reversed.

　　Absence of intermediary supervision encourages clinical fraud

　　In 1998, the relevant departments of the state promulgated the "Management Standard for Drug Clinical Trials (Trial)" (GCP for short), which was revised and implemented in 2003. The reporter’s investigation found that the binding force in the implementation of GCP is not strong, and the violations of relevant subjects such as pharmaceutical companies, intermediaries and doctors are prominent.

　　Driven by interests, some pharmaceutical companies have launched generic drugs, and the important and necessary link of clinical trials has been "ignored". The person in charge of a large pharmaceutical company in Jiangsu said that he had participated in the research and development of new drugs in a pharmaceutical company, in fact, he copied the newly developed innovative pharmaceutical materials from abroad. This pharmaceutical company spent a week preparing materials, and did not conduct clinical trials for six months at all. It even got the approval of "exclusive innovative drugs" very quickly. As a result, the effect of five domestic generic drugs is not obvious, but one foreign original drug is effective but can’t get in, which is a typical phenomenon of "bad money driving out good money".

　　The absence of supervision by CRO encourages the falsification of clinical data. A person in charge of a CRO revealed that CRO should be a third-party inspection agency, which plays a role in quality control of drug research and development, clinical application and approval. However, due to the lack of transfer threshold of domestic CROs and vicious competition of a large number of unscrupulous enterprises, many CROs have become accomplices in data fraud driven by interests. "Some pharmaceutical companies know that CRO is fraudulent, but considering that CRO shares the illegal costs and risks, they often turn a blind eye. What’s more, some pharmaceutical companies made it clear that if the test fails to pass the acceptance, it will not pay, forcing CRO to make fraud. "

　　A law enforcement officer of the food and drug supervision department said that during the inspection, it was found that the main body of clinical trials should be doctors, but some CROs hired a large number of assistant researchers instead of doctors to do clinical observation, data statistics and quality verification, which was an important reason for the irregular and untrue data.

　　Clinicians’ professional ethics is out of order, which opens the door for data fraud. The chief physician of a third-class hospital in Guangdong said that he had participated in the third-phase clinical trial of an obstetric drug under the leadership of another hospital. "The actual operation is not strict." Many records that are beneficial to the marketing of this drug have been saved, and adverse clinical cases or experimental data have been erased. Especially compared with similar drugs, the fraud situation is more prominent. "Doctors are very busy, clinical trials will not be done seriously, and there is no time to make such rigorous records. Many of them are done by CRO, and the authenticity is naturally greatly reduced."

　　Clinical supervision has become a weak link in the drug supervision system. Some people in the industry believe that drug regulatory authorities at all levels are generally short of regulatory talents and technical teams with clinical background, and long-term emphasis on system certification and neglect of clinical project process supervision, especially the safety and effectiveness evaluation of post-marketing drug clinical trials, and supervision is almost blank. A staff member of Jiangsu drug supervision system said that compared with GMP inspection team, there is a big gap in the ability of local clinical verification GCP team, and the personnel and technology can not keep up with the current requirements.

　　Beware of negative arguments weakening supervision.

　　The reporter’s investigation found that over the past year, the self-inspection and verification of drug clinical trial data has achieved remarkable results, initially curbing the situation of large-scale data fraud, and some pharmaceutical companies feel unprecedented pressure.

　　"In the past, there was almost no clinical supervision. Now we suddenly asked for self-examination and verification, which caught us off guard." A person in charge of a pharmaceutical company in Inner Mongolia complained that the storm of verification of clinical trial data was "a matter of punishing the Qing Dynasty with the laws of the Republic of China". The state’s policies can’t be changed constantly, and we can’t take the "opinions" and "regulations" issued today to consider what we did before.

　　The person in charge questioned why so many CRO companies were approved. Why did the test data provided by CRO company pass the review before? Why are clinical trial institutions approved by administrative departments not conducting regular trials? Why should the applicant bear most of the responsibility for a series of mistakes made by the regulatory authorities? "These problems need to be paid attention to by relevant management departments and explained reasonably."

　　Some people in the industry believe that there are two negative arguments to be vigilant against this unprecedented storm of clinical supervision. First, the introduction of policies should conform to China’s national conditions, and the requirements for innovation at this stage should not be too advanced; Second, the policy cannot be uniform, and some clinical data are just not standardized, not fraudulent, and should be allowed to exist.

　　Yu Dechao said that at present, it is a critical period to control "bad money drives out good money" in the field of drugs, and real innovation must be encouraged with the strictest system. Once the clinical fraud is spared, the result must be "a small gap becomes a big hole." "If a pharmaceutical company is allowed to falsify, then other pharmaceutical companies will follow suit. Therefore, we must adhere to zero tolerance and not relax about clinical fraud. "

　　In fact, compared with the United States, China’s drug supervision still needs to be strengthened. The State Food and Drug Administration has made it clear that if the clinical research data are fraudulent, the applicant’s new application for drug registration will not be accepted within three years, and the clinical trial data of the person directly responsible for participating in the research or organizing the research will not be accepted within ten years.

　　Dr Liao Guojuan, CEO of Suzhou Jinweizhi Biotechnology Co., Ltd. said that in the United States, once data fraud occurs, pharmaceutical companies and R&D personnel will be blacklisted and will not be allowed to enter related fields for life.

　　Insiders suggest that the country should actively integrate domestic pharmaceutical companies with the international market, establish an internal supervision system for pharmaceutical companies, and truly form core competitiveness through innovation in order to occupy a place in international competition.

Jiang Yan, the Goddess of Craftsmanship： Let China equipment reach a new height.

CCTV News:She is the first designer of ethylene compressor in China, breaking the long-term foreign technical monopoly; She created the first million-ton ethylene compressor in China and climbed to the peak of design technology in the same industry in the world. She is just an ordinary design director, but she leads the team to undertake 60% of the design tasks of the largest compressor manufacturer in China.

She is Jiang Yan, a professor-level senior engineer of Turbine Design Institute of Shenyang Blower Group Co., Ltd. During the historical journey of localization of major equipment, she worked hard and made great achievements, and became a veritable "dream catcher" for the industry to serve the country.

The birth of a miracle

After graduating from university in 1997, Jiang Yan stepped into the door of Shengu Group with great enthusiasm and became an ordinary designer. At first, she only made static equipment such as auxiliary machines, and was a "layman" of dynamic equipment such as compressors. After the research on the steering gear, she grew up from an ordinary technician to a senior engineer with her enthusiasm and amazing perseverance, and witnessed and participated in the technical progress of Shengu in the first line of design.

Ethylene, a compound composed of two carbon atoms and four hydrogen atoms, is one of the largest chemicals in the world, which constitutes more than 70% of petrochemical products. Its output is regarded as one of the important indicators to measure the development level of a country’s petrochemical industry.

Ethylene compressor can be called the "heart" of ethylene industry, and the million-ton ethylene compressor represents the highest level of petrochemical equipment. For a long time, the design and manufacturing technology of large ethylene compressors has been monopolized by a few countries.

In 2006, the state decided to build three million-ton ethylene projects in Tianjin, Zhenhai and Fushun. Shengu Group undertook the task of developing a million-ton ethylene compressor for these three projects. It is a historical opportunity that must be grasped to end the history of passive dependence on imports and get rid of the embarrassing situation of being controlled by others.

Jiang Yan was only 33 years old when he received the R&D task. Young, not good at talking, and not graduated from a famous university, can this seemingly soft and weak woman break through the "hard ice" that Chinese people have been trying hard for decades? If it can, it must be a miracle.

But miracles are always created by people.

After taking over the task and provoking the "burden", Jiang Yan and her colleagues shuttled between major refining and chemical plants in China day and night, climbing the workbench of imported ethylene plants with a height of tens of meters over and over again to observe the appearance structure and operation; Visit major scientific research institutes in China again and again, visit, consult and discuss; Study hard one after another thick original foreign language materials … … Design failure, modify the design, fail again and modify again. After unremitting efforts, Jiang Yan and her team redesigned the structure of the compressor and successfully put it into use.

At 18: 00 on February 22, 2011, the first domestic million-ton ethylene compressor was successfully tested in the assembly workshop of Shengu Group, which made China the fourth country in the world to independently design and develop million-ton ethylene compressors.

From 450,000 tons, 800,000 tons, 1 million tons to 120 tons, Shengu Group has accumulated more than 1,000 compressors so far, completely ending the passive situation of China’s long-term dependence on imports of ethylene compressors and directly saving the country 5 billion yuan in imported equipment funds. With the hard work of "Jiang Yan", developed countries have gone through 100 years in the field of ethylene compressor development, while China only took 10 years.

The goddess is a model worker and a mother.

Jiang Yan is famous for her diligence in the factory. On the day before her daughter was born, she still kept the habit of being the first to work in the office every day. It is this hard work that has won her the title of Shenyang Special Model Worker, Liaoning May 1st Women’s Advanced Individual, National May 1st Labor Medal and National Model Worker. On April 28th, 2013, as a representative of industrial workers in Shenyang, she spoke in the Great Hall of the People and was personally received by the General Secretary of the Supreme Leader.

The goddess model worker is an excellent female craftsman in the country, but she is also the wife and mother of a family.

In 2012, there was a problem with the compressor of a domestic enterprise. Jiang Yan, who just got off the plane from the scene and saw her husband, cried in a big mess. "At that time, I really thought, I hope something will happen on the plane, and I won’t have to worry about it the next day." Her lover has been patiently asking what happened. As a colleague, the husband can always detect his wife’s thoughts at the first time and slowly enlighten him. In Jiang Yan’s heart, her husband will always be his most solid backing.

Because of work, Jiang Yan owed too much to her daughter since she was a child. In 2013, my daughter was hospitalized with a bad cold. As a mother, she was unable to accompany her little daughter to take care of her because of the Huizhou project. There is still a short message from her daughter in her mobile phone: "Mom, I have been waiting for the bus in the snow for 40 minutes, but I have not come yet. I am freezing and crying. I miss you to pick me up."

Sometimes, after a long business trip, Jiang Yan took out her daughter’s photos on her mobile phone and looked at them. She said that her 14-year-old daughter is 1.7 meters tall, with good academic performance and independence. Having her is the greatest achievement and happiness in this life.

one

The craftsman heart of the goddess

In Jiang Yan’s mind, the so-called "great country craftsman" must "sit on the bench and keep an eye on the computer."

Jiang Yan’s design team is mostly young people born in 1980s and 1990s, with an average age of less than 30 years old. They are full of energy but not ostentatious, and they are practical and diligent. "Doing things one step at a time, walking too fast, you will feel empty one day." Jiang Yan said.

"Sister Jiang is the absolute guarantee of the project!" For apprentice Han Shuai, the customer named Jiang Yan to lead the design, which made him feel proud as an apprentice.

After 1985, Han Shuai officially worshipped Jiang Yan as a teacher in 2015. "Sister Jiang is a strong woman." He secretly rejoiced when he learned that he would become Jiang Yan’s apprentice. But it is this "female man" who is resolute in her work, but she treats her colleagues delicately and gently in her life. Han Shuai said, "In winter, if anyone’s home heater is broken, Sister Jiang will lend them her own electric heater."

Jiang Yan said frankly, in fact, I’m not just "Jiang Yan", but I’m representing 7,300 employees of Shen Gu who have made silent contributions in their posts. She believes that the craftsman spirit is more about loyalty to the enterprise and persistence in the profession. She said, I remember our leader said: "Ten years ago, when I visited a Japanese enterprise, I saw a craftsman grinding the weld. Ten years later, the old craftsman still stuck to his post and did the same job."

"Be sure to be practical!" This is the most important trait that Jiang Yan thinks as a craftsman, and this is also the evaluation of the model worker director by the young people in the design room of the Turbine Design Institute where Jiang Yan is located: "simple, practical and honest".

Jiang Yan said, "In the future, we will never be followers and imitators, but leaders and leaders. As ‘ Old advanced ’ Technical personnel of state-owned enterprises, I will aim at the forefront of world science and technology, shift our products from high-speed growth stage to high-quality development stage, and promote more ‘ Made in China ’ Trend ‘ China created ’ Make your own contribution to building an innovative country.

How is the price performance？ Toyota Fenglanda gave a minimum of 7.4 fold.

Many consumers think that the cost of buying a car plus the cost of maintaining a car every year is really a lot of money, but now taxi software is so popular that it is convenient and cheap to take a car, and it is not practical to buy a car. However, in bad weather such as cold or hot, carrying a heavy shopping bag or dragging a huge suitcase, or when the driver is in an emergency, he will feel the pain of waiting. Although cars are consumables, and even the rate of preservation is not high, there is no denying that owning a car of your own can really bring great convenience to life, such as going to go on road trip.

Today, we will take a look at this new car, Fenglanda, in terms of its design, rough interior and high and low performance. Presumably, small owners have dived into major forums and dug up numerous evaluation videos, so there is no need to repeat it in small series. Now, our focus is on the transaction price, discount, sales volume and value preservation of Fenglanda, so as to help small owners who are basically targeting and waiting for the opportunity to start judging whether it is worth winning.

This site has collected the real transaction price of Toyota Fenglanda in the past year. The lowest transaction price of Fenglanda in the country in the past month was 127,400 yuan, the highest cash discount for new cars was 34,200 yuan, and the maximum discount for new cars reached 7.40 fold! The price is for reference only, and the actual transaction price is subject to the local dealer.

Choose a car to buy a car? The difficulty of choosing a good car is almost catching up with the college entrance examination to fill in the volunteers! But in fact, it is not difficult to choose a car. It really depends on the sales volume. What everyone likes can’t be worse.

Try to choose the opportunity of callback to intervene.

Guosheng Securities said that recently, the market started to gain momentum under the policy combination of management, and the overall index maintained an upward trend, which is also the direction selected by the market after two weeks of sideways shocks. Once the trend is formed, if you want to reverse it, you need more short-selling power. In the current market environment where short-selling forces are suppressed layer by layer, the probability of a sharp decline is small. Therefore, the best choice at the moment is to follow the trend, and short-term adjustment is a better entry layout point, which can actively seize the opportunity. Strategically, because the current market is dominated by plate rotation, the game of theme plate is weak, so it is necessary to pay attention to controlling the rhythm, try to choose the opportunity of callback to intervene, and choose the target with better overall trend as the right bargain-hunting layout. In the direction, we can pay attention to the trend layout opportunities of smart driving, consumer electronics and artificial intelligence.

Hualong Securities pointed out that, after the previous high dividend sector and the theme of scientific and technological innovation achieved good performance continuously, the market showed a certain degree of "high cutting and low cutting" phenomenon, which was mainly manifested in switching to the direction of low valuation and value. The medium and long-term high dividend and the theme of scientific and technological innovation remained the main line of the market, and in the second half of March, it paid attention to the possible opportunities in industries such as pharmaceutical biology, electronics, building materials, architectural decoration, power equipment, non-bank finance, machinery and equipment and related topics.

Central china securities believes that the average P/E ratios of the Shanghai Composite Index and the Growth Enterprise Market Index are 12.37 times and 30.57 times respectively, which are below the median level in recent three years, and the market valuation is still in a low region, which is suitable for medium and long-term layout. Boosted by many favorable factors, the overall stock index is expected to maintain a volatile pattern in the future, and it is still necessary to pay close attention to the changes in policy, capital and external factors. Investors are advised to pay short-term attention to investment opportunities in industries such as consumption, agriculture, animal husbandry, feeding and fishing, and resources.

Wearing white protective clothing, we are like a great white guard for health, and we will definitely protect you from going ashore safely! ｜ Angel Diary

　　In the face of the novel coronavirus epidemic, there are such a group of people who are racing against death. They are parents, wives, husbands and children … … But in the face of the epidemic, they are "angels" dressed in white robes. Voice of China’s "Angel Diary", the fourteenth article, records the daily work of the "angels in white" and captures the touch of the frontline of the "war epidemic".

　　It was cloudy on February 10th, 2020.

　　I am Wu Man, a nurse of endocrinology in Houhu Hospital of central hospital of wuhan. Today is the 17th day of my work in the front line of the "epidemic". On February 8, when I was nursing the patient Mr. Yi Lao, I overheard him say, "Tomorrow is my birthday, and I really want to eat a bowl of longevity noodles." After work, I posted this in the work group, and my colleagues wanted to do something for Mr. Yi Lao. Huang Ruxian, a nurse in gastrointestinal surgery, accepted the task of longevity noodles. Near noon on February 9, Huang Ruxian made a birthday cake with bread at home, inserted some candles, and then made longevity noodles. I, Huang Ruxian and other nurses sent cakes and longevity noodles to Mr. Yi Lao, and played birthday songs, clapping their hands to bless him and cheer him up.

　　Mr. Yi Lao said to us: "You have made me spend an unforgettable 76th birthday, and I have regained my confidence in defeating the virus. Although you are wearing protective clothing and masks, you can’t see your faces clearly, but I believe you are all the most beautiful angels in white. "

　　On February 10th, 2020, it rained in Wuhan.

　　I am Dr. Wei Qi from the Department of Hepatobiliary and Gastrointestinal Surgery of Wuhan Hankou Hospital. Today is the 20th day of my participation in the fight against COVID-19 (rescue work), and now I am mainly responsible for the emergency treatment and management of critical patients in fever clinic. The emergency room has been overloaded for a long time, and we have worn all kinds of protective clothing and n95 masks. It is really different every day, but we can still overcome it.

　　My wife is also a nurse in our hospital. Now she is in the isolation ward. The most worrying thing is that she has two babies, who are taken care of by her grandmother alone in the country. She is a very strong person. Every time she calls, she says that her family is fine, so that we can work in the hospital with peace of mind. But I can imagine that a six-year-old and a three-year-old child are naughty, and she may even be in a hurry to cook. Now I hope that the people of the whole country will work together to overcome this epidemic!

　　It will be cloudy on February 10th, 2020.

　　I am Wang Yanli, a doctor in the Department of Respiratory Medicine of Wuhan Children’s Hospital, which is the only designated hospital for children in novel coronavirus, Wuhan. My sisters and I have been working in the isolation ward for 15 days.

　　Two days ago, it was the Lantern Festival. Most of my colleagues forgot this festival, and the careful head nurse Li Wenqing didn’t forget it. Early in the morning, after arranging the affairs of the department, she quickly asked the nurse in the rest area to cook the dumplings, and sent the hot dumplings to each hospitalized patient: "Come, have some sweetness." Although we didn’t eat dumplings or reunite with our families, it was warm to look at their smiling faces. There was something warm on my mind that day. In the afternoon, I went out of the ward and went back to the rest area to prepare for dinner. I found that the nurses and sisters were all busy in the small classroom, and soon the table was filled with all kinds of food we could find, as well as a small cake. I just know that the head nurse’s birthday has passed two days. Everyone made an appointment to make up a new birthday for the head nurse. As soon as the head nurse entered the door, she was moved to cry. Each of us was more than one meter away and sent her blessings one by one. The pistachio of the department said that we will never forget this day.

　　It was cloudy on February 10th, 2020.

　　I’m Jing Wong, head nurse of the first isolation ward of Xiaogan Central Hospital. Today is the 12th day for me to take part in the fight against the COVID-19 epidemic. These days, I am mainly responsible for ward management, clinical nursing and organization and coordination with Chongqing Aid Hubei Medical Team.

　　In addition to basic treatment, we will also give spiritual encouragement to patients every day and strengthen their determination to recover, such as our grandfather in bed 37 — — The 67-year-old critically ill patient was very depressed when he first moved in. Through our daily psychological comfort and chat, he is now obviously relieved compared with before he was hospitalized, and he can even eat by himself. I hope all the patients in the hospital have the same determination and belief in recovery as him. At this moment, if there is a fast-forward button, I hope to go directly to the day when we win the battle!

　　It was cloudy in Wuhan on February 10th, 2020.

　　I am Ge Shengting, a nurse in Hongqiao Campus of Huashan Hospital affiliated to Fudan University in Shanghai. Today is the seventh day of my work in the front line of the "epidemic".

　　After the construction and planning a few days ago, the Wuchang shelter hospital where we are located has gradually entered the right track. Today, it’s my first time to enter the cabin. Seriously, even if I do a good job in psychological construction and stand in front of the gate of the "patient area", my heart beats faster. I pushed the door open and the scene behind it was peaceful. From 8: 00 am to 12: 00 noon, the first "4 hours" I entered the warehouse whizzed past. My uncles and aunts, like my relatives, care about whether I am tired or not. Although my back is soaked, I still don’t want to miss every second of caring for them. Our shelter is like a big ship sailing in the stormy waves, and we in white protective clothing are like a great white guard for health. We will protect you from going ashore safely!

　　It was rainy on February 10th, 2020.

　　I’m Liu Qihui, a nurse in the ICU of cardiac surgery in Hainan Provincial People’s Hospital. Today is the 14th day of my arrival in Wuhan and the 11th day of my fight against COVID-19. I called my grandparents last night and lied to them. I was busy in the hospital (Hainan Provincial People’s Hospital) and may not have time to call them. As a result, they said they already knew that I was in Hubei. I hope I can call them often to report my safety and pay attention to safety! I stopped for a few seconds to reply. Okay. Grandpa used to be a soldier in the 34th Division of the 12th Army of Nanjing Military Region. He said, "When one side is in trouble, all sides can support it. Now it’s your turn to go to the battlefield. Be sure to pay attention to safety and take care of yourself! " Grandpa, I will definitely come home to see you when the epidemic is over. You from afar, please rest assured that we will return safely!

　　It was cloudy in Wuhan on February 10th, 2020.

　　I am Zhou Jienan, a member of the National Emergency Medical Rescue Team of the Second Xiangya Hospital of Hunan Central South University. Yesterday was my 29th birthday, and I came to Wuhan from Hunan. Before I left, I went to the hospital staff barber shop to get a haircut as my special birthday present. This inch is the same as mother’s.

　　In May 2014, her mother, who was also a nurse in the Second Xiangya Hospital, underwent radical mastectomy on the right side and received four stages of chemotherapy. Before she lost all her hair, she decided to take the initiative to give up, and shaved a monk’s head without stopping. I knew she was afraid that I would look uncomfortable every day. After shaving my head, my mother smiled and asked me: Is it okay?

　　After four courses of chemotherapy, black grass quietly emerged from her head. Slowly, my mother made the transition from a buzz cut to a lovely and delicate short perm.

　　On February 9, with the same optimism, I cut a cut with the same paragraph as my mother. It not only saves the time of care, but also facilitates the putting on and off of isolation and protection facilities. Taking advantage of my 29th birthday, I would like to say thank you for your hard work, for giving birth to me, for educating me to grow up with me, and for teaching me to fight the disease with the same inch.

　　I will come back safely. At that time, we will abandon the masks. I want to tell you something about my trip.
