Why should the Taoist temple be built on the mountain?

First of all, because Taoism advocates Laozi's idea of "Taoism is natural", it is necessary to observe and understand Taoism in a place close to mountains and rivers. Furthermore, Taoist architecture contains the mystery of Taoist culture in China, that is, the mystery of the word "Guan". Laozi's "purple gas coming from the east" is itself a cultural landscape-the light of oriental wisdom, so Taoist buildings can also face the east. Laozi's Tao Te Ching and Yijing are identical in culture, and both belong to the category of natural culture, so they also conform to China's concept of geomantic omen.
