Chen Jingrun (1933~ 1996) is a mathematician in China and an academician of China Academy of Sciences.

Fujian Minhou people. Chen Jingrun was born in a small clerical family, ranking third with his brothers and sisters. Because there are many children at home, my father's income is meager, and family life is very tight. So Chen Jingrun seems to be a burden to his parents from birth, a person who thinks he is unwelcome.

After school, I was often bullied because I was thin and weak. This special life situation has shaped him into an extremely introverted and inarticulate person, and his fascination with mathematics has made him develop the habit of being alone and thinking behind closed doors, so he is considered a "freak" by others.

. Chen Jingrun chose to study mathematics all his life, which was related to Professor Shen Yuan. There, Chen Jingrun first learned about Goldbach's conjecture, that is, from there, from the first moment of Chen Jingrun, he was determined to take off the jewel in the crown of mathematics.

1953, he graduated from Xiamen University and stayed in the library to work, but he never forgot Goldbach's conjecture. He sent his math paper to Professor Hua, who appreciated his talent and transferred him to the Institute of Mathematics of China Academy of Sciences as an intern researcher. From then on, under the guidance of Hua, he was lucky enough to enter Goldbach's conjecture.

1966 In May, a dazzling new star flashed over the global mathematics world-Chen Jingrun announced that he had proved "1+2" in Goldbach's conjecture; 1972 February, completed the modification of "1+2" certificate. Incredibly, foreign mathematicians use large high-speed computers to prove "1+3", while Chen Jingrun relies entirely on paper, pens and skulls. If this is puzzling, then the six sacks of manuscript paper he used to simplify the proof of "1+2" is enough to explain the problem.

1973, he published the famous "Chen Theorem", which is considered as the glorious culmination of the screening method.

For Chen Jingrun's achievements, a famous mathematician abroad once marveled and was deeply moved: he moved mountains and poured seas!

I can give you the materials.

But how can I make A3 tabloids for you?

Write it yourself. It won't take long.
