Kan, the way of heaven; Authentic, authentic. Kanyu is Feng Shui, one of the traditional Chinese cultures.

"Historical Records" will be Kanyu family and the five elements of the family in parallel, there is a look up at the sky, look down on the geography of the meaning, later generations to look at the feng shui people said: "Kanyu home", so Kanyu in Chinese folk also called feng shui.

Kanyu: Kan, the meaning of the earth, representing the word "terrain"; "Chengyu" means to study the topography and features, focusing on the description of landforms.

Kanyu is based on the Hetu Luo book, combined with the eight trigrams and nine stars and the five elements of yin and yang, and completely combines the operation of heaven and earth's air flow and people in it to form a special theoretical system, so as to infer or change people's good fortune and misfortune, and live and die poorly.

"The funeral is also angry. The qi is dispersed by the wind, and the boundary water is stopped. The ancients gathered to make it not disperse, and the line made it stop, so it was called feng shui. This passage is from the Book of Burial written by Guo Pu of the Jin Dynasty, which is the first time that the word "feng shui" appears in ancient Chinese literature.

Guo Pu succinctly explained the fundamentals of the theory of "Feng Shui": taking "vitality" as the core, Tibetan wind and water as the conditions, seeking an ideal burial environment as the focus, and blessing the descendants as the ultimate goal. As for how to define the quality of feng shui, Guo Pu's view is: "Obtaining water is the first, and Tibetan wind is secondary."

The ancient book contains: The air is dispersed by the wind, and the boundary water stops. The ancients gathered to make it not disperse, and the line made it stop, so it was called feng shui. He also said: "If there is no water, the wind will arrive and the air will disperse, and if there is water, the air will stop and the wind will not be, so the word feng shui is the most geological." Among them, the land of water is the first, and the land of Tibetan wind is secondary. “

"The Book of Water Dragons" also has "the water flies away, the anger is dispersed, and the water melts and the internal qi gathers", "when you don't see the mountain, you first look at the water, and there is a mountain without water to find the land" and so on, all of which illustrate the importance of wind and water.

For the houses in the wilderness and valleys, because of their close relationship with the surrounding natural geographical environment, more attention is paid to the form; As for the house of Jingyi, because it is limited by the external environment, it is often used in combination with the law and the law.

However, both the "Situation Sect" and the "Rational Qi Sect" follow the three basic principles of the unity of heaven, earth and man, the balance of yin and yang, and the mutual growth and restraint of the five elements.
