　　Yaozishan Village Road, located between sanjiang town and Shuimo Town, Wenchuan County, has a narrow winding road, and few vehicles pass at ordinary times.

　　On August 21st, this ordinary village road became a life passage for sanjiang town to the outside world, and a large number of tourists trapped by floods were transported out of the mountain.

　　Sanjiang town, 80km away from Chengdu, surrounded by mountains and fresh air, is a summer resort for tourists in summer. A heavy rainfall in the early morning of the 20th caused local flash floods, with no power, water and gas, and no signal. The county road leading to Shuimo was interrupted by mudslides.

　　After the flood, the local government and fire rescue forces organized local villagers’ private cars to transfer a large number of tourists out of the mountain through Yaozishan Road.

　　A disaster

　　The flood struck in the early hours of the morning

　　Township streets are in ruins.

　　When the flood hit, people in sanjiang town were already asleep. "Who would have thought that there was such a big flood suddenly in the middle of the night?" Lao Zhou, the owner of sanjiang town farmhouse, is sad. His farmhouse is in a low-lying area and has been flooded.

　　In the memory of the local elderly, sanjiang town has never encountered such a fierce flood.

　　At 2 o’clock in the morning on the 20th, many tourists who were already asleep in the farmhouse were awakened by a fierce knock on the door. "The flood is coming, get up quickly and go to the town government to hide!"

　　The small river that crosses Sanjiang Town is a tributary of Minjiang River, which is called "Zhonghe" by local people. After continuous heavy rainfall, the water level soared and the river overflowed onto the highway beside the river, and people sought safe places to avoid danger.

　　On the morning of 20th, the reporter followed the rescuers of the provincial fire brigade from Chengdu, passed Dujiangyan, Shuimo and Yaozishan Road, and arrived in sanjiang town at 6 pm.

　　After the flood peak in sanjiang town, a thick layer of silt accumulated on the streets. Trees, sundries and stones carried by the flood piled up on the street, and many cars parked in low-lying places were washed away and overturned. The streets of sanjiang town are in ruins.

　　An embarrassing road

　　Take the baby to Sanjiang for the summer.

　　In the event of a rare flash flood

　　Uncle Zhao and his wife are from Shuangliu, Chengdu, and they are both over 70 years old. It was sweltering in Chengdu in August. On August 7th, they took their grandchildren and went to sanjiang town for the summer with their relatives. The farmhouse food and shelter, as long as 80 yuan per person per day.

　　Unexpectedly, most of the streets in sanjiang town were flooded in the early morning of 20th. They were awakened by the owner of the farmhouse and rushed to sanjiang town Primary School to avoid danger. Like Uncle Zhao and his wife, many tourists who came to Sanjiang for the summer vacation from Chengdu were caught off guard. Some tourists’ cars parked in the street were washed away or damaged, causing heavy losses.

　　Mr. Yang’s family, a Chengdu tourist, arrived in sanjiang town only one day before the flood. Unexpectedly, they were hit by the flood in the early hours of the next morning, and their car was washed away without a trace.

　　After the flood, sanjiang town was caught in the predicament of water, electricity, gas and no cell phone signal, and tourists were looking forward to leaving here early.

　　A rescue

　　Village road becomes life channel.

　　Tourists were transported out of the mountain.

　　Due to mountain torrents, mudslides and landslides, the county road from sanjiang town to Shuimo Town has been interrupted, making it impossible to pass. There is only one village road that can pass. The local people call it Yaozishan Village Road, which can lead to Shuimo Town. However, this village road is very narrow. At many corners, two private cars can’t get on the wrong bus. In addition, the continuous rainfall has brought great difficulty to the evacuation of tourists.

　　In order to transport tourists out of the mountain in time, the sanjiang town municipal government organized a large number of private cars of local villagers, and at the same time, traffic control was implemented on Yaozishan Village Road, allowing only local vehicles to transport tourists back and forth, but not foreign vehicles.

　　From noon on the 20th, some tourists with cars were evacuated by Yaozishan Road under the guidance. A large number of tourists who don’t have cars line up and get out of the mountain in villagers’ private cars under the guidance of the local government.

　　On the morning of the 21st, the trapped Uncle Zhao and his wife boarded a private car, walked through the village road for three hours, arrived in Dujiangyan city at 12 noon, and finally got out of danger.

　　According to the Propaganda Department of Wenchuan County Committee, as of 2 am on the 21st, there were 6,200 tourists to be transferred in sanjiang town. At present, the transfer of tourists continues.

　　Kunming, August 26 (Xinhua) The reporter learned from the Forest Public Security Bureau of Jingdong County, Yunnan Province that a national second-class protected wild animal, the Chinese gazelle, recently broke into the homes of local farmers, and the farmers called the forest public security bureau for help.

　　On the 22nd, a "monster" suddenly broke into the home of a villager in Wenjing Town, Jingdong County. Its horns were like antlers, the head of a sheep, the hoof was like a cow’s hoof, and the tail was like a donkey’s tail, which was a realistic version of the "four unlike".

　　It strayed into the pigsty after a while in the yard. The villagers quickly shut it up and called the local forest public security bureau for help the next day.

　　The police of the Forest Public Security Bureau of Jingdong County rushed to the villagers’ homes. After careful identification, it was confirmed that the monster that broke into the farmhouse was named Chinese gazelle, which belongs to the national second-class protected wild animal. The police analyzed that it may be due to the heavy rain in the local area. After walking out of the nearby forest, the Chinese gazelle mistakenly broke into the villagers’ homes.

　　It is understood that the Chinese gazelle, also known as the Ming-bristle sheep, belongs to the family Bovidae and is a typical forest-dwelling animal. It is one of the typical animals in the tropical and subtropical regions of southeast Asia, and mainly lives in mixed coniferous and broadleaved forests, coniferous forests or rocky miscellaneous shrub forests at an altitude of 1,000-4,400 meters.

　　After careful examination, the police did not find that this Chinese gazelle was injured and aggressive, so it was judged that it had the ability to survive in the wild and was suitable for being released into nature. Subsequently, the police took this Chinese gazelle to a suitable location in the wild and released it to nature. (Miao Chao Zhou Wei)

　　The express delivery number publicly sold online is 50 cents each.

　　"I almost fell for it!" Talking about the express claim phone that I just received, Jin Zhu had a lingering fear. "When I lost the bank card number, password and reserved mobile phone number, I realized that it was wrong. Isn’t this a fraud?"

　　Recently, Jin Zhu, a Beijing citizen, was almost defrauded by telecom. The other party used the loss of express delivery and double claims as bait to trick him into a trap. The reporter’s investigation found that due to the epidemic situation, there is a backlog of express delivery nationwide, and criminals have used the psychology of consumers eager for express delivery to commit fraud in many places, and an illegal interest chain for selling express logistics information has been formed. The police in many places reminded that if you receive a courier claim call, you should not trust it. You should immediately contact the official customer service hotline of the courier company.

　　False claim

　　Pay for lost goods by "leaving a password"

　　During the epidemic, several couriers of Jinzhu were delayed. One courier sent from Zhejiang has not moved since it arrived at the Beijing transshipment center on February 29th. Jin Zhu didn’t care too much. "If not, let the seller reissue it."

　　So more than a month passed. Last week, he suddenly received a strange mobile phone number registered in Xingtai, Hebei Province. The other party claimed that it was a courier "customer service". "This person accurately knows all the information of my courier, including my name, address and courier ‘ Do not move ’ The state, he said that the courier has been lost, and it is necessary to pay double the value of the goods. "

　　"Customer Service" asked Jin Zhu to add WeChat, and then they had a voice call. Under the guidance of "customer service" step by step, Jin Zhu paid attention to a "claim settlement" WeChat official account, and then began a series of operations such as binding bank cards. Until the bank card number, password and reserved mobile phone number were involved, Jinzhu began to wake up. "I understood at once that this is fraud."

　　Hang up the voice call, ask the official express customer service, contact the e-commerce seller, and report to WeChat customer service … … After a series of operations, Jinzhu’s back was still cold. "I was bored. How did the liar know that my courier didn’t arrive?"

　　What a leak

　　Express information is 50 cents a piece.

　　Xiao Bai, an insider, said that this is a commonplace topic. In the online shopping process, there are many links from sellers to buyers, and any link may be leaked. In order to help Taobao sellers make up sales, there are even acts of publicly selling express delivery numbers online.

　　The reporter logged into a single number network, which has a large number of express numbers, covering the whole country, involving almost all express companies, and is updated every day. For 0.5 yuan, you can buy a courier number. The reporter tried several times and used the courier company official website to verify and found that all these single numbers were true. Through the single number, you can know the delivery place, receiving place and real-time status of the express delivery. However, the mobile phone number of the consignee is not displayed, and the name of the consignee is rarely displayed.

　　Xiao Bai revealed that after 2017, most courier companies began to adopt "privacy sheets" to protect customer information. "But not all couriers are using privacy sheets because it involves hardware and time costs." The reporter received a courier on April 9, and the complete mobile phone number was displayed on the packing list.

　　It’s difficult to find the consignee’s mobile phone number from the open trading order number. Is there any other way? Yes. In 2017, a case occurred in Jingzhou, Hubei Province, in which 11 courier employees stole and leaked more than 13 million pieces of citizen information. In 2018, a case in which a hacker illegally invaded and stole nearly 100 million pieces of citizen information was exposed. In 2019, a courier company in Nanjing, Jiangsu Province colluded with outsiders, involving the disclosure of about 500,000 pieces of citizen information. This information has been or is intended to be used for accurate fraud.

　　"Basically, in addition to insider stealing, it is hacking." Xiao Bai introduced that after the implementation of the "Provisional Regulations on Express Delivery" on May 1, 2018, the act of revealing user privacy can be fined up to 100,000 yuan.

　　Despite the legal constraints, the illegal act of revealing the privacy of express users has been repeatedly banned and has become an accomplice of telecom fraud. In recent years, there have been many cases of claims fraud caused by the backlog and delay of express delivery in many parts of the country. For example, on March 11, Tianjin Baodi police issued four cases of express claims fraud, involving a total amount of more than 100,000 yuan. The police reminded that the courier company would not contact the claim through the personal mobile phone number. Once receiving the claim call from the "customer service staff", it should remain calm and communicate with the official customer service and e-commerce platform of the courier company in time.

　　Recently, the 7th China Intangible Cultural Heritage Expo was held in Shandong. Male prostitute, Peking Opera Mask, Tai Ji Chuan, Guangshan Huagu Opera, Tang Sancai Burning Skills, Xuzhou Xiangbao, Miao Xiu and other representative non-legacy skills, new works and special performances from all over the country were exhibited. A total of 332 non-legacy inheritors and 284 non-legacy projects participated in the exhibition.

　　At present, 42 non-legacy projects in China have been selected into UNESCO’s non-legacy list and roster, making it the country with the largest number of non-legacy projects in the world. Behind this achievement is the unknown efforts and efforts of non-genetic inheritors in previous dynasties. Intangible cultural heritage, as an important symbol of the historical and cultural achievements of the country and the nation, not only bears the unique national memory, but also survives in the people’s lives in the process of generation replacement, which is of great significance for building a socialist cultural power.

　　China is rich in intangible cultural heritage resources. Up to now, there are more than 100,000 intangible cultural heritage projects at all levels. With the joint efforts of the whole society, many intangible cultural heritages have re-emerged with new vitality. However, compared with many traditional cultures and traditional skills that are facing the risk of cutting off their inheritance, how to protect and explore the intangible cultural heritages so that they can "survive" and "catch fire" is still the top priority of our intangible cultural development.

　　The key to let the non-legacy "survive" and "fire up" is to work hard to train the inheritors. China’s intangible cultural heritage projects are all amazing to the world, and once the skills of ancestors appear age or technical fault, there is a risk of being lost. Faced with the stringent requirements of intangible cultural heritage achievements, only a handful of people can bear the title of "non-genetic inheritor" with excellent skills after big waves. And if you want to inherit and carry forward the glorious legacy, you can’t do it quickly. Undoubtedly, the process of learning non-legacy skills has to endure hardships and loneliness. It is often necessary to concentrate on studying for several years or even more than ten years, carefully carving day after day, and silently sticking to the initial intention and persistence of non-legacy. A few days ago, the General Offices of the General Office of the Central Committee of the CPC and the State Council issued the "14th Five-Year Plan for Cultural Development", which clearly stated that "strengthening the cultivation of non-genetic inheritors." It can be said that the key to strengthening the inheritance of intangible culture lies in people, and it is urgent and imperative to cultivate more non-genetic inheritors.

　　Cultivating more non-genetic inheritors requires more policy support. At the government level, it is necessary to refine the relevant policies and give comprehensive guidance. Improve the record system of intangible cultural heritage investigation, grasp the overall situation, focus on representative projects, start with the identification and system of inheritors, explore the standards and methods of identification, and form policy support for the cultivation of non-genetic inheritors.

　　At the social level, it is necessary to strengthen the education of non-legacy science, especially from dolls, and set up non-legacy education bases to make more children interested in non-legacy. In addition, it is necessary to carry out the communication activities of intangible cultural heritage in various ways, and plant the concept of "non-inheritance is great and glorious" in people’s hearts, so that young people engaged in the study of intangible cultural heritage can gain more understanding and respect from society and families.

　　It is necessary to "fire up", but also to expand the market, to actively embrace new technologies and glow with new vitality. We see that with the organic combination of new technologies and intangible cultural heritage, the spread of intangible cultural heritage has completely broken through the geographical restrictions. With the help of new opening methods such as internet plus and VR, intangible cultural heritage IP has become fashionable among young people. For example, a martial arts game combined with Xijiang Qianhu Miao Village, the first Miao village in the world, and three representative non-genetic inheritors of Miao nationality, added Miao cultural elements to the plot, architecture and costumes, which made more young people interested in exploring non-heritage students. The essence of ancient culture from China also entered the homes of ordinary people and passed down imperceptibly in the digital age.

　　Chinese excellent traditional culture is the root and soul of the Chinese nation, and intangible cultural heritage, as an indispensable part of it, should be passed down through generations while continuing its glory. It is believed that with the continuous expansion of the market, more talents will join the team of inheritors and the team of protecting intangible heritage, so that intangible heritage can be better integrated into the daily life of Chinese and inject new vitality into the protection and inheritance of intangible heritage.

In the human body, there are two important cell groups: stem cells and immune cells, which each play an indispensable role and jointly safeguard our lives and health.

Stem cells: the "supplement" of the body

Stem cells are special cells with multi-directional differentiation and self-renewal ability. They are like "supplements" of the body, and can differentiate into other types of cells as needed, which makes them have great potential in medical research.

● Hematopoietic stem cells can differentiate into blood cells such as red blood cells, white blood cells and platelets, which is of great significance for the treatment of blood system diseases, such as leukemia and anemia.

Umbilical cord mesenchymal stem cells can differentiate into a variety of tissue cells, have immunomodulatory and anti-inflammatory effects, and can be used to treat various tissue injuries and diseases, such as myocardial infarction, arthritis and cirrhosis.

● Neural stem cells can differentiate into neurons, astrocytes and oligodendrocytes, which have potential application value in the treatment of nervous system diseases, such as Parkinson’s disease, Alzheimer’s disease and brain injury.

……

Immune cells: the body’s "guard"

Immune cells refer to cells directly involved in or related to immune response. They are like the "guards" of the body, which can identify and remove foreign pathogens. From the most common bacteria, viruses and fungi in daily life to abnormal cell cancer cells in the body, powerful immune cells will sound the alarm at the first time and start fighting to maintain the stability of the internal environment and protect human health.

What are the main cells?

T lymphocytes can directly destroy infected cells.

● B lymphocytes can quickly eliminate re-invading pathogens.

● NK cells can directly attack and destroy infected cells and abnormal cells.

Macrophages can swallow and digest pathogens and other foreign bodies.

……

What are the differences between stem cells and immune cells?

1. Different production times

Stem cells usually begin to be produced in the fetus.

Immune cells are usually produced after birth.

2. Different shapes

The shapes of stem cells are usually diverse, such as hematopoietic stem cells are round, oval and long, and neural stem cells are radial.

The shape of immune cells is more uniform, round or oval.

3. Different distribution

Stem cells are mainly distributed in bone marrow, fat, teeth, umbilical cord and placenta.

Immune cells are mainly distributed in tonsils, lymph nodes, thymus, bone marrow and other parts of the human body.

4. Different quantities

Generally speaking, the number of stem cells in the body is relatively small. A 30-year-old healthy person has about 1 billion stem cells in his body. Among them, umbilical cord and placenta have the most abundant stem cells.

The number of immune cells is very large, and the number of immune cells in healthy adults is between 40 trillion and 60 trillion. Among them, the number of white blood cells accounts for more than 95%.

5. Different sources of acquisition

Stem cells can be obtained from many sources, including blood, bone marrow, umbilical cord blood, fat, skin, dental pulp and nerves.

Immune cells are mainly obtained from blood.

6. Different functions

Stem cells have the ability of multi-directional differentiation and can differentiate into many cell types.

The main function of immune cells is to identify and eliminate pathogens in the body.

If the human body is regarded as a huge factory, then stem cells are like engineers. They continue to produce new cells and provide necessary nutrition and support for all parts of the body through continuous differentiation, so that our body can continue to operate.

Immune cells, on the other hand, are like cleaners of machines, always alert to and remove any potential threats, including foreign pathogens, harmful substances in the body and abnormal cells in the body. When the body is damaged or aged, they will also appear immediately and start the repair and cleaning work, thus maintaining the balance and stability of the body.

In a word, it is

Stem cells do addition and immune cells do subtraction!

7. Different clinical applications.

More than 20 stem cell products, such as umbilical cord blood hematopoietic stem cells, bone marrow mesenchymal stem cells and adipose-derived stem cells, have been approved for marketing in the world to treat graft-versus-host disease, degenerative arthritis, Crohn’s disease and refractory anal fistula. In China, hematopoietic stem cell transplantation has been widely used to treat hematological diseases such as leukemia, lymphoma and myeloma, while other types of stem cells are still in the clinical research stage.

Immune cell products such as T lymphocytes, DC cells and CAR-T cells have been widely used in the world, especially in cancer treatment, and immune cell therapy has become one of the emerging treatment methods. There are only two CAR-T cell products approved for marketing in China, which are mainly used to treat hematological tumors and solid tumors. But because of its high price, it has not been widely used at present.

Stem cells and immune cells are significantly different in function and characteristics, but they are both important guarantees for our vitality.

Through "cross-border cooperation", stem cells and immune cells can double the role of "regeneration+cleaning". In 2018, the paper "Two to Tango: Dialogue between Immunity and Stem Cells in Health and Disease" was published in Cell magazine, which showed that the combined therapy of stem cells and immune cells can maintain the homeostasis in the human body and has important application value in anti-aging. In addition, the "strong combination" of the two can also play an important role in brain injury, autoimmune diseases and so on.

With the continuous progress of science and technology, our research and application of stem cells and immune cells are also deepening. In the future, we are expected to make better use of stem cells and immune cells, providing unlimited possibilities for treating diseases and improving the quality of life.

Due to the improvement of watermelon varieties and planting techniques, this year’s local watermelons are listed ahead of previous years. In order to facilitate local melon farmers to sell melons in the city, standardize the behavior of selling melons, and fully meet the needs of citizens’ lives, the Urban Management and Law Enforcement Bureau of our city set up real estate watermelon sales points 20 days earlier than last year, and at the same time ensure the sanitation and order of the city appearance and environment. The city adopted the "three-fixed" method of fixed location, fixed area and fixed responsibility, effectively standardized the sales of real estate watermelons in urban areas, and rationally planned fixed locations. On the basis of fully considering the dual needs of urban management and citizens’ life, 149 temporary watermelon sales points were selected and set up in the urban area this year. From June 1 to August 30, a "watermelon map" was drawn, covering the main areas of the built-up areas such as Langya District, Nanqiao District, Economic Development Zone and Suzhou-Chuzhou High-tech Zone, and the general public, melon farmers and mobile phone new media were informed in time.

A new invention: thermal liquid sensor was tested and verified in Chentian laboratory.

　　During the awarding ceremony of the 2017 Qiu Chengtong Science Prize, I talked with Professor Yao Qizhi, an academician of the Chinese Academy of Sciences, an academician of the American Academy of Sciences and a Turing Prize winner.

　　On the eve of the Spring Festival, Li Chentian, a 17-year-old high school student from Zhuhai, went to the United States at the invitation of Tsinghua University to participate in the "Global Innovation Experience Camp" jointly organized by Tsinghua and Washington University. He won the best project award in this innovation challenge by virtue of the "active high-voltage power line deicing monitoring system" invented on the spot. Later, he flew back to Beijing, as a participant in the last ISEF (International Science and Engineering Grand Prix), and introduced his experience to the young people who were participating in the 2018 ISEF project selection and international exchange winter camp.

　　He invented the fluorine-free electronic refrigerator at the age of 9, the solar intelligent outdoor manhole cover management system at the age of 12, and the programmable terminal and operating system at the age of 13. So far, he has nine national invention patents … What kind of "awesome person" is Li Chentian? Why have you achieved so much at such a young age? The all-media reporter of Guangzhou Daily takes you to know the young man who is praised by the outside world as "Edison" in China.

　　At the age of 5, I designed light-controlled lanterns for myself.

　　Last weekend, when the reporter saw Jerry Lee Tianshi, he wore an old school uniform and black-rimmed glasses, which was very low-key; He was a little shy when he didn’t talk, but when he started talking about his invention, Li Chentian hardly stopped for more than two hours, and he spoke as fast as a machine gun. When I met some professional terms, I was a little confused when I watched the reporter. He kept changing his body movements to explain it.

　　Li Chentian’s family said that his whimsy began in childhood. My father said that he showed a strong interest in electricity when he was learning English in the early morning. Every time he was carried out by his mother and saw the neon lights flashing on the street, he would dance. "How can anyone be on the TV?" "How can a toy car automatically turn?" ….. Since I was two years old, I have often asked my parents who are all from liberal arts to be speechless.

　　Because of her strong interest in electronic products, at the age of five, Chen Tian borrowed her cousin’s middle school physics textbook for self-study. On the Spring Festival that year, the family was going back to their hometown. Before leaving, they were worried that the red lanterns hanging on the balcony of Zhuhai’s home were left unattended in the morning. They had been on for more than ten days, which was both a waste of electricity and a fear of causing safety accidents. He sprouted the idea of designing a light-controlled switch. "It will automatically turn off the lights when there is sunshine during the day and turn on the lights at night when there is no sunshine." As a result, he removed a sensitive relay from a radio through two days of fiddling, and really made such a switch through transformation.

　　However, in the eyes of Chen Tian, the first real invention was the "fluorine-free electronic refrigerator" he built when he was 9 years old. Later, he was out of control. At the age of 12, he invented the "solar intelligent outdoor manhole cover management system", and at the age of 13, he developed the "programmable cloud-and-thing terminal and operating system" … At the age of 12, he won the first prize in the Guangdong Youth Science and Technology Innovation Competition for six consecutive years and won the national first prize three times. At the end of last year, Chentian won the Science Award and the Silver Award in Computer Science in the 2017 Qiu Chengtong Middle School Science Award Global Finals with his paper "Universal Power Adaptation Protocol (UPP) and Its Implementation". From provincial and municipal competitions to going abroad to represent China teenagers in ISEF, Li Chentian has won more than 30 scientific and technological innovation competitions, and has successfully applied for 9 national invention patents.

　　All whimsy comes from life.

　　"There is no epiphany in science. I just invested enough time in invention and creation. I just started the accumulation of’ 10,000 hours’ earlier." Li Chentian said modestly that to make inventions, we must first have a strong interest and then invest a lot of time.

　　Chen Tian said that you should be curious when making inventions and pay attention to everything that happens around you. All my whimsy comes from life. The idea of the project "Active High-voltage Power Line Deicing Monitoring System" when I participated in the Innovation Challenge in the United States originated from the ice disaster in 2008. He was deeply impressed by the embarrassing picture of manual mechanical deicing in the power sector on TV, so he always had an idea, "If the frozen wires can be deiced automatically, even the wires in the alpine zone can not be frozen!" Over the past few years, he has done a full technical demonstration for this project, and this global innovation experience camp just gave him such an opportunity. Chen Tian said, "Due to sufficient technology accumulation, the original prototype of this project took only two days, and finally won the highest award’ ‘Best Project Award’ in the participating projects."

　　The topic he is working on, "Variable Temperature and Pressure Pump", was inspired by his parents taking him skiing in Harbin during the winter vacation in 2016. At that time, he saw a small vendor barbecuing with liquefied gas on the street, and the fire went out. As a result, he saw the small vendor cover the gas bottle with a towel, pour some boiling water on the towel, and the fire "sprayed" again. He said that when he saw this phenomenon, he was very excited and thought that this phenomenon might solve the problem of transporting low-viscosity liquids such as refrigerants that he had always wanted to solve. If the pressure in the pump chamber is changed by changing the temperature instead of moving parts such as piston, wouldn’t it be possible to manufacture a pump without moving parts?

　　Parents support the "disruptive" behavior of disassembling and tampering with household appliances from an early age.

　　Chen Tian said, "If I make small achievements, I would like to thank my parents for their tolerance and support." Since childhood, his parents never forced him to attend interest classes, and he was not required to be a schoolmaster. He said that he has never attended any cram school since he went to school. During the holiday, he either stayed at home to make inventions or participated in scientific and technological competitions and exchanges in various places.

　　Parents also fully support the "disruptive" behavior of dismantling household appliances that they have shown since childhood. Just in the first grade of primary school, in order to study the temperature control switch, I dismantled a newly bought electric heating plate imported from Germany at home in the morning. At that time, the market price was more than 2,000 yuan. When he was 9 years old, he developed a fluorine-free electronic refrigerator. In order to buy a refrigerator, his parents took him to Beijing to find many shops, and finally spent three days scouring Zhongguancun for the desired products.

　　In order to support his son’s innovation and invention, his father set up a "morning lab" for him at home. In this laboratory, the reporter saw a laser positioning machine, a small supercomputer with 72 cores, a multifunctional calibration measuring instrument with data stability of 2ppm, a multifunctional vector network analyzer and a very advanced mixed-signal oscilloscope.

　　"Over the years, the equipment in this laboratory alone has invested more than one million yuan, not including thousands of old electronic products that he invents and buys every time and dismantles." Chen Tian’s father smiled and said, "If we only talk about the electronic laboratory, my laboratory may be the best in Zhuhai."

　　However, apart from scientific and technological inventions, Chen Tian has no other hobbies. As long as he doesn’t go out to participate in scientific and technological competitions and exchanges in his spare time, he basically stays in this laboratory.

　　Learning computer programming in the fifth grade of primary school is painful to cry.

　　Li Chentian does not agree with the reputation of the outside world as a "genius boy". His parents have repeatedly stressed that their children have only shown strong interest in electrical appliances and circuits since childhood, and they are ordinary teenagers. "He is only willing to spend time on electronics," my father said seriously. "Since I was a child, I love to disassemble things. Others sell old household appliances at home, and my family often buys them back from outside."

　　Chen Tian added that every design or invention is not always smooth sailing, and there are many failures. There are two or three thousand discarded circuit boards at home. And when learning theoretical knowledge, I once had the idea of giving up. With the deepening of scientific research, he had to learn computer programming for a project in the fifth grade of primary school. Most of the electronic components encountered before are concrete things, while computer assembly language is too abstract. For a child in the fifth grade of elementary school, it is like reading a gobbledygook at first. "If you don’t understand, you can’t learn!" Sometimes I read until late at night, and in the morning I said that I was so miserable that I cried and wanted to give up several times. Finally, with the encouragement of his father, he persisted, and it took him more than a month to write the first program-"digital clock". Looking at the success of the first string of code written by myself, Chentian jumped with excitement. "He was yelling, and then he ran downstairs from upstairs and kept shouting, Dad, I made it up." Dad recalled.
