What is rational feng shui?

Rational formula, also known as orientation method, ancestral hall method, house method, compass method, etc. Because it mainly originated in Fujian and spread in Fujian (including Zhejiang and Sichuan), it is also called Fujian School. The origin of rational style can be traced back to Duke Buchloh of Zhou. Later, during the Spring and Autumn Period and the Warring States Period, Yin and Yang studies prevailed. Guo Pu in Jin Dynasty put forward the content of rational style: "Twenty-four mountains are divided into yin and yang, and forty has eight innings." Li Style was mainly founded by Wang Ji and Chen Tuan in Song Dynasty. There are many representatives of rational style and many works. Among them, Qingnang Haijiao Jing is a classic of rational style. The rationale is based on the four basic principles of eight diagrams, twelve branches, stars and five behaviors, paying attention to orientation and many taboos. Its theoretical framework covers almost all fields covered by the Book of Changes. Yin and Yang, Five Elements, River Map, Luo Shu, Eight Diagrams, Stars, Ghosts and Gods, Yin Na and Qimen are all the foundations and principles of physical management, so the theory is extremely complicated, which is difficult for ordinary people to understand. For example, some people think that the name of the ancestral hall is five elements, while others think that it is the water of the ancestral hall.
