The word "Feng Shui" first appeared in the Book of Burial written by Guo Pu, Jin Man, in ancient China, saying that "the burrier takes advantage of anger". Qi dissipates by the wind, and the boundary water stops. So it's called Feng Shui because old people get together to make it last and their deeds stop. This famous classic sentence is the first time that the word "Feng Shui" appeared in China ancient literature. This paper briefly expounds the purpose of the theory of "Feng Shui": based on Yin and Yang, with "anger" as the core, with the condition of hiding wind and getting water, with the starting point of finding an ideal tomb environment and Yin Fu's children and grandchildren as the ultimate goal. Its "getting water is the best, and hiding the wind is the second." "The selection criteria of feng shui pointed out the direction for later famous teachers to find auspicious places. The Book of Burial vividly expresses the contradictory unity of motion and static, emphasizing that "Qi" is composed of the relative balance and organic combination of motion and static. " The Collection of Books established a clear and systematic ideological system for Feng Shui and became a milestone in the development of Feng Shui theory.
"If there is no wind, gas will gather, and if there is water, gas will melt." The ancients should first look at the geographical environment of the mountains, and then choose their own auspicious places to build battlements and tombs, so as to achieve the highest state of unity between heaven and earth.
