What are the introductory knowledge of Yang Zhai Feng Shui?

Feng Shui, one of the five traditional physiognomy techniques, was originally physiognomy, that is, the method of looking at geography on the spot, which was called physiognomy, and it was called Feng Shui theory in ancient China. Its purpose is to choose the methods and principles of palace, village site selection and cemetery construction, and choose a suitable place. Feng shui has a long history. In ancient times, geomantic omen prevailed in China cultural circle, which was a very important factor in daily life. Many documents related to Feng Shui have been preserved. As can be known from the literature, ancient geomantic omen was mostly used in the site selection of towns and villages, as well as the construction of palaces, and later developed to find funeral terrain. Gao Yuxiang, director of China Architectural Geomantic Research Association, advocates dialectical study of geomantic omen, removing its dross and taking its essence, and explaining geomantic omen phenomenon in a scientific and reasonable way. Its use in divination is actually just a kind of psychological comfort. Although there is some truth, it can only be used to avoid disaster. If there is no practical action, everything will be in vain, and we should not indulge in it.
