One day, Chen Jingrun touched his head during lunch. Alas, his hair is too long. He should get a haircut at once, or others will think he is a girl. So he left work and ran to the barber shop.
There are so many people in the barber shop that everyone cuts their hair next to each other. Chen Jingrun's brand is the small brand number 38. He thought it was too early for me to turn now. Time is so precious that I can't waste it. He hurried out of the barber shop, found a quiet place to sit down, then took out a small notebook from his pocket and recited new words in a foreign language. He recited it for a while and suddenly remembered that when he was reading a foreign language in the morning, there was one place he didn't understand. You must understand what you don't understand. This is Chen Jingrun's temper. He looked at his watch. It's only half past twelve. He thought: check in the library first, and then come back for a haircut. He stood up and left. Who knows, not long after he left, it was his turn to get a haircut. The barber's uncle shouted, "Number 38! Who is number thirty-eight? Come and get a haircut! " Think about it. Chen Jingrun is reading in the library. Can he hear the barber's uncle calling number 38?
After a long time, Chen Jingrun found something he didn't understand in the library, and then went to the barber shop happily. But he passed by the foreign language reading room, and there were all kinds of new books, which were really nice. He ran in and read another book. It was not until the sun went down that he remembered to cut his hair. As soon as he touched his pocket, the little sign No.38 was still lying well. But what's the use of his coming to the barber shop? This number is outdated.
As soon as Chen Jingrun entered the library, it was like falling into a honey pot, and he couldn't bear to leave. Yes, another day, Chen Jingrun had breakfast, took two steamed buns and a pickle, and went to the library.
Chen Jingrun found the quietest place in the library and read carefully. He stayed until noon and felt a little hungry, so he took out a steamed bun from his pocket and was still reading while eating.
"Ding Lingling ..." The bell rang, and the librarian shouted, "It's time to get off work, please leave the library!" The somebody else all gone, but Chen Jingrun didn't hear, or 1 vigorously in reading.
The librarian thought that everyone had left the library, so he locked the library door and went home.
Time passed quietly and it was getting dark. Chen Jingrun looked out of the window and said to himself, What a strange weather it is today! It's sunny for a while and cloudy for a while. He pulled down the switch wire of the light and sat down to read. Watching, he suddenly stood up. It turned out that he read a book all day and began to understand. Now, he will go back to the dormitory and continue to do the problems he left unfinished yesterday.
Chen Jingrun put the book away and went out. The library is quiet and there is no sound. Hey, where's the janitor? Why doesn't anyone come to read? Chen Jingrun looked at his watch. Ah, it's past eight o'clock in the evening. He pushed open the locked door; He shouted at the door: "Please open the door! Please open the door! " But no one answered.
In normal times, Chen Jingrun will go back to his seat and continue reading until the next morning. But, not today! He's going back to the dormitory to do that unfinished problem!
He went to the telephone and called the office. But there was no answer, only a beep. He dialed this number several times, but no one answered. What shall we do? At this moment, he remembered the secretary of the Party Committee and dialed the telephone immediately.
Chen Jingrun? The party secretary was surprised when he received the phone call. He was overjoyed, looked into it and said with a smile, "Chen Jingrun! Chen Jingrun! You have worked hard, you are really a good comrade. "
The party secretary immediately sent some comrades to the librarian. The door of the library opened and Chen Jingrun said to the librarian, "I'm sorry! I'm sorry! Thank you, thank you! " As he spoke, he ran down the stairs and returned to his dormitory.
He turned on the light and set about solving the problem at once.
When Chen Jingrun was studying in Huaying Middle School in Fuzhou, he was lucky enough to listen to a learned math teacher transferred from Tsinghua. He told his classmates a world math problem: "About 200 years ago, a German mathematician named Goldbach proposed that' any even number can represent the sum of two prime numbers', abbreviated as 1+ 1. He never proved it in his life, so he wrote to Euler, a mathematician in St. Petersburg, Russia, and asked him to help prove the problem. After receiving the letter, Euler began to calculate. He tried to prove it to the death. Later, Goldbach passed away with a lifetime of regret, but left this mathematical problem behind. For more than 200 years, Goldbach's conjecture has attracted many mathematicians, making it a big unsolved mystery in mathematics. " The teacher also made an interesting metaphor here. Mathematics is the queen of natural science, and Goldbach conjecture is the jewel in the queen's crown! This fascinating story left a deep impression on Chen Jingrun, and Goldbach's conjecture attracted Chen Jingrun like a magnet. From then on, Chen Jingrun began the arduous process of picking the crown jewels. ......
1953, Chen Jingrun graduated from the Department of Mathematics of Xiamen University, and once stayed there. He works as a librarian in the library. In addition to sorting out books and materials, he is also responsible for correcting homework for students in the mathematics department. Despite the tight time and busy work, he insisted on studying math science. Chen Jingrun has a keen interest in mathematical theory. He used all available time to systematically read the mathematical monographs of Hua, a famous mathematician in China. While continuing to learn English, Chen Jingrun learned Russian, German, French, Japanese, Italian and Spanish, so as to read foreign materials directly and master the latest information. Learning these foreign languages is an amazing breakthrough for a mathematician, but it is only the first step for Chen Jingrun.
In order to make his dream come true, whether it is hot or cold in Chen Jingrun, he can't sleep at night in that small room of less than 6 square meters, and concentrate on his studies. Only the calculated toilet paper is fully packed with several sacks. From 65438 to 0957, Chen Jingrun was transferred to the Institute of Chinese Academy of Sciences. As a new starting point, he studied harder. After 10 years of calculation, 1965 in May, he published the paper "Big even number represents the sum of the products of a prime number and no more than two prime numbers". The publication of the paper has been highly valued and praised by the world mathematics community and famous mathematicians. British mathematician Haberstein and German mathematician Li Xite wrote Chen Jingrun's paper into a math book called "Chen Theorem". However, the elites in the field of mathematics in the world don't know the classification of commodities in their daily life, and some commodities can't be named, so they are called "idiots" and "weirdos".

Writer Xu Chi described Chen Jingrun's inner world in Goldbach Conjecture: "I know my illness is very serious. I'm terminally ill. Bacteria are devouring my internal organs. My mind has reached the point of exhaustion. My body really can't support it! Only my brain cells are extremely active, so I can't stop working. I can't stop. "For Chen Jingrun's contribution, Chinese mathematicians once said: Chen Jingrun challenged the sum of the world's intellectual limits in the field of analytic number theory for 250 years. Deng Xiaoping, the chief architect of China's reform and opening-up, once told people meaningfully: "It would be great to have a thousand scientists like Chen Jingrun in China.".
Chen Jingrun's Short Stories: Chen Jingrun was born in a poor family. When his mother gave birth to him, he had no milk and lived by borrowing rice soup from his neighbors. At the age of going to school, my father, who works as a clerk in the post office, earns too little for my eldest brother to go to school, and my mother has to carry her little sister under two years old to work in the fields to earn money. In this way, the burden of looking after the 3-year-old brother on weekdays falls on Xiao Jingrun's shoulder. During the day, he led his little brother to sit on a small bench and count his fingers. When my brother is out of school at night, I beg him to tell him math. When I was older, I squeezed out the gap to help my mother work in the fields and was busy practicing writing and calculus. Seeing that he is eager to learn, his mother sent him to Chengguan Primary School. Although he is thin, he works hard and gets good grades, which makes the children of rich families jealous and kicks him. He couldn't beat those people, so he went home crying and asked to quit school. His mother stroked his wound and said, "Son, we are bullied only because we are poor." You should be eager to learn, fight for breath, grow up and be promising, and then they won't dare to bully us! "Xiao Jingrun dry tears, and went to do homework. Since then, he has never shed tears again, turning physical and mental pain into a driving force for learning, and his grades have been top-notch. Finally, I was admitted to Sanyuan County Junior High School with the first place in the school. In junior high school, he was specially cared for by two teachers: one was a Chinese teacher who was nearly sixty years old and a professor. He witnessed the Japanese bullying, but the Kuomintang was losing ground, and he felt saddened. It's a pity that he is old and places his hopes on the next generation. Seeing that Chen Jingrun is diligent and promising, he often calls him to his side to talk about the 5,000-year history of China's civilization, encouraging him to study hard and shoulder the heavy responsibility of saving the motherland. Teachers often speak with tears in their eyes, and Chen Jingrun also said with tears that he will serve the motherland when he grows up! The other is a math teacher under the age of 30. He graduated from the Department of Mathematics of Tsinghua University with rich knowledge. Chen Jingrun was most interested in math class, a textbook, which was finished in only two weeks. The teacher felt that this student was unusual, so he told him more carefully, further inspiring his patriotic enthusiasm, saying, "If a country and a nation want to be strong, it is absolutely impossible for natural science to be underdeveloped. Mathematics is the foundation of natural science." From then on, Chen Jingrun loved mathematics more. Until I graduated from junior high school, I kept a record of straight A in mathematics. After Chen Jingrun recovered, Chen Jingrun was admitted to Huaying College in Fuzhou to attend high school. Here, he was lucky enough to meet Mr. Shen Yuan, whom he will never forget. Mr. Shen used to be the dean of Tsinghua University Aviation Department and the head teacher of Chen Jingrun. He also taught math and English. Mr. Shen is knowledgeable and persuasive, and all his classmates like to listen to his lectures. Once, Mr. Shen came up with an interesting classical math problem: "Han Xin ordered soldiers". Everyone began to count, and Chen Jingrun quickly replied in a low voice: "53 people". The whole class was stunned by the speed of his calculation. Teacher Shen looked at the quiet and disheveled student and asked him how he got it. Chen Jingrun blushed and could not speak. Finally, he wrote the method on the blackboard with a pen. Teacher Shen said happily, "Chen Jingrun is fine, but he is afraid to speak. Let me help him! " Aft that lecture, Mr. Shen introduced China's contribution to mathematics in ancient times, saying that Zu Chongzhi's research on pi was 1000 year earlier than that of Western Europe, and Qin in the Southern Song Dynasty solved the simultaneous linear equation more than 500 years earlier than the Italian mathematician Euler. Teacher Shen then encouraged and said, "We can't stop. I hope you can create greater miracles in the future. For example, there is a Goldbach conjecture, which is still an unsolved problem in number theory. People compare it to a jewel in the crown. You should take it off! "After class, Miss Shen asked Chen Jingrun what he thought. Chen Jingrun said quietly, "May I? Teacher Shen said, "Since you can come up with the idea of' Han Xin ordering soldiers' by yourself, you will be able to find the pearl in the future: nothing is difficult to a willing mind! "That night, Chen Jingrun couldn't sleep. He swore that he would work hard at all costs when he grew up, whether he was successful or not!
