The Origin of China's Ancient Prose
What is "Feng Shui"? There are countless people who have defined Feng Shui since ancient times. Guo Pu, who first defined geomantic omen in history, said in his famous book "The Book of Burial": "When the burials are angry, the gas will be dispersed by the wind, and the boundary water will stop. The ancients gathered to stop it, so it was called Feng Shui. The method of geomantic omen is water first and wind second.
It can be seen that the technique of geomantic omen, that is, the technique of knowing each other, is the core of people's choice of living or burying environment and dealing with the law of cosmic change, so as to achieve the goal of seeking good fortune and avoiding evil. Feng Shui can be divided into Yang Zhai and Yin Zhai.
