"The queen of natural science is mathematics, the crown of mathematics is number theory, and Goldbach conjecture is the jewel in the crown." He conquered "1+2" in the world-famous mathematical puzzle Goldbach's conjecture, and this conclusion was named "Chen Theorem", which created the distance from the crown jewel of "1+ 1". 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".
