Where does the theory of "reinforcing fasting" come from?

The so-called "Bu Zhai" was first seen in Shangshu Zhao Gao: "Taibao () is near Luo, Bu Zhai. If you get it, you will move it. "

That is to say, after Zhou Ke's business, he chose Luoyang's website to establish Luoyi. Oracle bone inscriptions unearthed in Yin Ruins recorded that there was a Buzhai character "Zhen: A Great City Made of Tang Earth" (Jin 611). "Mao Yibu, for zhen; Wang, emperor, I come from the Tang Dynasty "(570 BC); "GengWuBu, c zhen; Wang Yi is a city, here, if the emperor "(C 86) and so on. At this time, divination means investigation and choice, not just divination. Buzhai lived for the choice of land, and the original Buzhai was mostly used for the location and construction of settlements and cities. There are two main contents: one is to decide on a good day to start work; The second is the choice of construction address. However, this divination fact is at the level of seclusion, and there is no technical problem in how to build it. It is the earliest mysterious light of Feng Shui.
