Wang Chongyang
According to traditional legend, Wang Chongyang met two Taoist immortals in the summer of 1159 CE. The immortals, Zhongli Quan and Lü Dongbin taught him Taoist beliefs and trained him in secret rituals. The meeting proved deeply influential, and roughly a year later, in 1160, Wang met one of these men again. In this second encounter, he was provided with a set of five written instructions which led to his decision of living by himself in a grave he created for himself in Zhongnan Mountain for three years.
