In the thirty-fourth year of Qin Shihuang (2 13 BC), Prime Minister Li Si began to discuss book burning. Chen Yu, a Wei national, told him: "Qin will destroy the legacy of the former king, and the son will be the owner of the book. It is dangerous!" He replied: "I am a useless scholar, and people who know me are just friends." If Qin is not my friend, why am I in danger? " I will hide it and wait for it. "So he collected books such as The Analects of Confucius, Shangshu and Xiao Jing from home, hid them in the wall of his old house, and then lived in seclusion in Songshan to teach more than 0/00 disciples.
Chen Sheng led the peasant uprising, and he joined the army against Qin. As a doctor and a surname, he stayed with him for consultation. Later, because Chen Sheng didn't listen to the admonition, the uprising situation took a turn for the worse, leading to ultimate failure. Finally, he died in the battle with General Qin at the age of 57.
