Yan Junping, also known as Zhuang Junping, was a Taoist scholar and thinker in the early Western Han Dynasty from 86 BC to 10. Zun, whose real name (Han Shu written by Ban Gu in the Eastern Han Dynasty was taboo by Han Liu Zhuang), was born in Chengdu, Shu County. Being good at Huang Lao, Emperor Cheng of Han Dynasty (reigned in the first 32 ~ 7 years) lived in seclusion in Chengdu, taking divination as his career (divining turtles to observe the people's movement), "guiding goodness according to the situation", preaching Laozi's moral classics and benefiting everyone. After retirement, he wrote a book and set up a library to teach Laozi and Zhuangzi in Pingle Mountain, Pixian County, and wrote a prophecy of Wang Mang's taking punishment and Wuxing on this mountain, which predicted two major historical events of "Wang Mang usurping power" and "Wuxing" more than 20 years in advance, and trained his proud disciple Yang Xiong. According to Laozi's philosophical thought, zhouyan wrote 10 more than ten thousand books. Gui Zhi's Taoist theory and philosophy were inherited by Yang Xiong, Wang Bi, Cheng and others, which became the germination of metaphysics in Wei and Jin Dynasties. After 9/kloc-0 died, he was also buried in Pingle Mountain, Pixian County. In the Ming and Qing Dynasties, the former one was lost because of the suspicion of the ancient school, and the latter one has only seven volumes so far.
