When did Taoism get involved with ghosts?

Machamp's Chaos God has nothing to do with Taoism, but an alchemist. During the pre-Qin hundred schools of thought period, Laozi was the originator of Taoism, and he didn't set foot in Machamp's alchemy, ghost hunting and other chaotic gods. It is more about thinking about the social universe of life.

What is an alchemist? In fact, it is a liar. Lian Changsheng is not a panacea, but it is just a means of deception. Of course, liars also pull tiger skins to make banners. At that time, people were very ignorant of nature, especially admired Zhouyi Bagua and Machamp's confusion, so it was natural to draw a tiger according to a cat. At that time, the Eight Diagrams in Zhouyi did not belong exclusively to Taoism, but was the source and representative of China culture, so even if the alchemist wore the Eight Diagrams fairy costume, it had little to do with Taoism.

The relationship between Taoism and alchemists began when Emperor Wu of the Han Dynasty deposed 100 schools, and the other 100 schools were in danger and wanted to find a place to live. Although Confucianism is the only one, Confucianism can only govern the country for the emperor, but it cannot provide the road to immortality. So hundreds of other schools want to get involved with theological theocracy to save themselves. After seeing Feng Shui, Yin and Yang teachers became Yin and Yang teachers, and Taoism also practiced elixir to study catching ghosts. It is in this situation that Zhang Daoling, the eighth great-grandson of Sean, a representative figure of Taoism, has a prominent position and is highly anticipated. Bound believers established Pentecostalism, and Taoism was officially related to ghosts. Its descendants are today's Dragon and Tiger Mountain.
