What contribution does Taoism make to Feng Shui?

Taoism is a native religion in China. Its purpose is to achieve the unity of heaven and man through the cultivation of the body and the use of nature, so as to break away from the secular and become immortal. Based on this idea, Taoism also pays attention to the study of the natural environment, from which Feng Shui has benefited a lot. Taoist classic "Taoist Collection" includes Feng Shui classic "Family Classics" and funeral etiquette book "Confucianism worships reason, exercises and filial piety" related to Feng Shui. The "Nine Planets" theory of management style and geomantic omen is to learn from Taoism. The geomantic classic "Nine Days Xuan Nv Qingnanghaijiao Classic" borrows the name of "Xuan Nv" from Taoist immortal spectrum. Qinglong, Baihu, Suzaku and Xuanwu were originally the protectors of four directions in Taoism, and Feng Shui formed the "four spirits" model with their names. The "fu Zhen" of Feng Shui draws lessons from the "fu Zhen" of Taoism, and the "hanging mirror" of Feng Shui draws lessons from the "looking at the demon mirror" of Taoism. The reference of geomantic omen to Taoist theories and methods also led to the emergence of Taoist priests who specialize in geomantic omen. These Taoists used the extensive folk foundation of Taoism to spread Feng Shui, and also used the effect of transforming Feng Shui to spread Taoism.
