A counterexample of knowledge changing fate

Chen Jingrun was born in a poor family, studied hard and worked as an apprentice in a grocery store, but he didn't give in to his fate, but kept on striving for self-improvement. Later, he taught himself mathematics at night, and then he went to Tsinghua. 1953, graduated from the Mathematics Department of Xiamen University, and once stayed in school. 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, although time is tight. 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 national 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 summer or cold winter, Chen Jingrun can't sleep at night without knowing the taste and studies hard. The calculated toilet paper alone is full of 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, which is called "Chen Theorem". Chen Jingrun finally solved the mystery of "Goldbach conjecture" in world mathematics, which was finally deciphered by Chen Jingrun, and the pearl in the queen's crown was finally picked by Chen Jingrun. The elites in the field of mathematics in this 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. By studying hard, the world was shocked. If he had given up on himself and wanted to be an apprentice, he would not have achieved great success today.
