What is the connection between residence and geomantic omen?

Feng Shui has become more and more colorful with the development of history. In the Han Dynasty, there was a saying that heaven and earth corresponded, which gave rise to many techniques of protecting each other. During the Wei and Jin Dynasties, the burial method was emphasized, and it was believed that people would choose a good place to be buried after death, so that their descendants could reproduce, so the book "Funeral Classics" came into being. Of course, we also study folk houses, the so-called "yangzhai". In the Sui and Tang Dynasties, there was a house classic. During the Song and Yuan Dynasties, this theory of geomantic omen was further developed. According to the History of Song Dynasty, there are three kinds of books about Yang Zhai's art, namely, Zhai Ti Jing, Xiang Zhai Jing, nine planets's Good or Bad Song, nine planets Zi Nian Jing, Zhai Xin Shi Jian Jing, Huangdi Ba Zhai Jing and so on. The so-called "nine planets" and "eight houses" are the main features of Yang houses since the Song Dynasty. This involves astronomy, geography and various folk cultures. Because this book is not devoted to Feng Shui, I won't go into details.
