Goldbach conjectures that this world-class mathematical problem that has been unresolved for more than 200 years has attracted the attention of thousands of mathematicians all over the world, but few people can really challenge this problem. In high school, Chen Jingrun listened to his teacher's philosophical remarks: the queen of natural science is mathematics, the crown of mathematics is number theory, and Goldbach conjecture is the jewel in the crown. This crucial enlightenment became his unswerving goal all his life. In order to prove Goldbach's conjecture and win the world-famous pearl of mathematics, Chen Jingrun trudged in the field of mathematics with amazing perseverance. Hard sweat has brought fruitful results. 1973, Chen Jingrun finally found a simple method to prove Goldbach's conjecture. After his achievement was published, it immediately caused a sensation in the world. Among them, "1+2" was named "Chen Theorem", also known as the "glorious vertex" of the screening method. Hua and other mathematicians of the older generation spoke highly of Chen Jingrun's paper. Mathematicians from all over the world have also published articles praising Chen Jingrun's research achievement as "the best achievement in studying Goldbach's conjecture in the world at present".
