Instead, he chose to work in the Ministry of Education and stayed there for several years. Then, he was transferred to the Ministry of Justice and worked in the Penal Department for five years.

However, for Li Zhi, these official positions are just a means to make a living. He never colludes with others and always leads an honest and clean life. 1580, at the age of 54, Li Zhi was appointed as the magistrate of Yao 'an, Yunnan. Although the court recognized his working ability and intended to give him a promotion, Li Zhi resolutely resigned and chose to leave the system. He didn't go back to his hometown, nor did he look for a clan, but he started a completely different road.

At the age of 62, Li Zhi shaved his hair and became half a monk. Asked if he was a monk, he replied that it was too hot. This behavior makes him an exception. Then, Li Zhi began to criticize traditional culture, invited Confucius to the altar, and claimed that saints were nothing.

Li Zhi not only criticized traditional ideas, but also advocated equality between men and women, and openly recruited female disciples. He established a close relationship with these female disciples, which was immoral for later Ming Dow scholars. However, this behavior caused widespread controversy and criticism, but it also attracted some people's approval and follow-up.
