Looking at the geomantic formula when robbing a tomb

Because it is "in the south", in geomantic omen, Qinglong, Baihu, Suzaku and Xuanwu are often used to indicate orientation. For example, The Book of Burial says, "Take the dragon on the left, the white tiger on the right, the suzaku in front and the Xuanwu in the back." "Ten Books of Yangzhai" said: "Anyone who has running water on the left side of the house is called Qinglong; There is a long road on the right, called white tiger; There is a sweat pool in front, called Suzaku; There is a hill behind, called Xuanwu, which is the most expensive place. " Thus, Qinglong, Baihu, Suzaku and Xuanwu became the names of the four gods in Feng Shui.

There is a fixed saying about the location of Qinglong and Baihu Mountain, that is, Qinglong is in the east and Baihu is in the west. But Feng Shui only has the names of dragons and white tigers, but it doesn't fix their positions. That is, the green dragon is often called the left wing, while the white tiger is the right wing and the right wing.

Four gods, such as Qinglong and Baihu, are orientation gods, and each town guards the city, town and house. Those who meet the following conditions can be called "land of four gods" or "land of four spirits". Its conditions are "Xuanwu bows its head, Suzaku dances, Qinglong winds and white tigers tame." That is to say, the peak in the direction of Xuanwu looks down, and the peak in the direction of Suzaku will come to sing and dance, the Qinglong Mountain on the left is constantly undulating, and the White Tiger Mountain on the right is vigorous. Such an environment is a "land of geomantic omen".

Silingdi is an environmental model in any geomantic space. Whether it is desirable or not depends on whether it conforms to the principle of "Xuanwu hangs its head, Suzaku dances, Qinglong winds and white tigers tame". This can be said to be a landscape model, influenced by the astronomical part of China's traditional philosophy and the traditional feudal etiquette of China.
