The Feng Shui of site selection lies in site selection.

Building site selection in ancient China is inseparable from Feng Shui. The guiding principle of Feng Shui is: the unity of nature and man. This principle has persisted throughout China's more than five thousand years of historical evolution and does not change with political changes and economic development. In terms of specific operations, it also summarizes the "Chengqi theory", "Hide the wind and get the water theory", "Looking for the dragon and tapping the acupoints theory - the four spirits theory", "The theory of mountains surrounded by water", "Situation theory", "Three Yuan Theory" Luck says” Wait. Under the guidance of the idea of ​​"unity of heaven, earth and man", Feng Shui emphasizes the harmony between man and nature. Feng Shui always regards the universe and the earth as the "qi" on which people rely for survival, and emphasizes "feeling the Qi of heaven and earth". Therefore, Feng Shui attaches great importance to the relationship between people and the natural environment. In the first part of "On the Appearance of the House", the "Ten Books on Yang House" specifically discusses the environmental issues of the house: "The place where people live should be mainly based on the earth, mountains and rivers. The energy of the pulse is the most important and has the most important influence on people's misfortunes and blessings. " Ancient Chinese architecture was greatly influenced by Feng Shui, which first manifested itself in the pursuit of a suitable aura, that is, the most beneficial external environment for human growth and development. In order to be in harmony with nature, the ancestors living on the Loess Plateau chose to dig into the earth and live in caves. Some people think that this may be the origin of the concept of "cave" in Chinese Feng Shui. This early architectural form has the characteristics of saving land, being warm in winter and cool in summer, windproof, gathering air, and directly sensing "rustic air". Therefore, many cave dwellings still exist on the Loess Plateau to this day. The soul of Chinese Feng Shui is the theory of "Qi". Chinese Feng Shui believes that a place containing "qi" is the most ideal when choosing a settlement location. In order to achieve the purpose of "gathering Qi", Chinese Feng Shui pays great attention to the interrelationship between various elements of the natural environment and the artificial environment: mountains must form a surrounding space from far to near; there must be flowing water in the planned area. "Surrounded by mountains and rivers, there must be energy" is a summary of the experience of Chinese Feng Shui practice. Some Feng Shui legends and stories further mystify the energy of Feng Shui.
