During the Ming and Qing Dynasties, geomantic omen had many influences on architecture. First of all, it is the choice of location. Almost all the houses and graves are selected according to the theory of Feng Shui, and Mr. Feng Shui often participates in village site selection. The principle of village location can be summarized as follows: the back of the mountain is facing the water, the mountains are beautiful, surrounded by hoses, the halls are spacious, and the nozzles are gathered. The so-called mountain dragon and water dragon refers to the situation of the mountain and river system, Tang Ming refers to the space where the village foundation is located, and the nozzle refers to the water inlet and outlet at the head and tail of the village. According to these principles, most mountain villages choose the environment of pillow mountain, surrounded by water and with screens; In plain areas, water is the dragon, and villages often adopt the layout of facing the street and water. The principle of urban site selection is the same as that of villages, but the environmental capacity is required to increase accordingly.
