Chen Jingrun is a famous mathematician in modern China and an academician of China Academy of Sciences. He has made remarkable achievements in analytic number theory and made a major breakthrough in the study of Goldbach conjecture, a world-famous mathematical problem. Chen Jingrun 1935 was born in a family of post and telecommunications workers in Minhou Town, Fuzhou City, Fujian Province. There are many children at home and poor economic conditions. Chen Jingrun was weak, introverted and unsociable when he was a child, so he was laughed at, abused and even beaten by his friends. But he has a strong interest in mathematics, and once he enters the kingdom of mathematics, he cares nothing. Later, Chen Jingrun entered Huaying Middle School in Fuzhou. One day, the teacher told the students a famous problem in number theory: 1742. The German mathematician Goldbach found that any even number can be expressed as the sum of two prime numbers. He tested many even numbers and the results were all correct. But he can't prove it, he can only call it speculation. He wrote to Euler, a famous mathematician at that time, asking him to help prove it, but Euler didn't give Goldbach the proof he wanted until his death. For more than 200 years, many mathematicians have tried to prove it, but all failed. As soon as the teacher finished speaking, the students began to talk about it. The teacher went on to say, "number theory is the crown of mathematics, and Goldbach conjecture is the jewel in the crown." You should set up lofty ideals from an early age, learn mathematics well, and take off the pearl in the crown of mathematics when you grow up. " The classroom was suddenly silent, and the students were lost in thought, as if thinking about something. Chen Jingrun also bowed his head, lost in thought, all this is too mysterious and attractive for him. He secretly made up his mind that he must study hard and pick this pearl when he grows up. After that, Chen Jingrun studied math harder. He not only worked hard to finish the math problems assigned by his math teacher, but also taught himself many math books. Once, the math teacher assigned 33 questions for students to choose 10. However, Chen Jingrun not only completed 33 problems, but also gave a variety of solutions for each problem. His math performance has always been the first in his class. In the second year of high school, Chen Jingrun was forced to drop out of school because his family was too poor. Surprisingly, by 1950, he was admitted to Xiamen University with the qualification of "equivalent academic ability". It took Chen Jingrun only three years to complete the four-year course of University Mathematics Department. 1953, Chen Jingrun graduated early as high flyers, and was given priority to be a teacher in a middle school in Beijing. However, Chen Jingrun's introverted personality is not suitable for being a teacher at all. He failed, so he had to leave middle school and set up a bookstall on the streets of Fuzhou to live. But he was lucky. Wang Yanan, president of Xiamen University, immediately asked Chen Jingrun to return to Xiamen University as a librarian. So that he can concentrate on his math. After coming to Xiamen University Library, Chen Jingrun felt like a duck to water in the Wang Yang sea of mathematics. He carefully studied the famous mathematician Hua's "Overlapping Primes Theory" and "A Guide to Number Theory", and carefully scrutinized every question in the book. He found some subtle mistakes in Hua's book. So he got up the courage to write a letter to Professor Hua and put forward his own views. After receiving Chen Jingrun's letter, Hua spoke highly of his insights and talents. Hua affirmed Chen Jingrun's point of view, and warmly invited him to attend 1956, the first national mathematics seminar, and read his paper at the meeting. After the meeting, Hua transferred him to the Institute of Mathematics of China Academy of Sciences in Beijing.
