What are Yanglong and Yinlong?

The so-called yang dragon and yin dragon can be divided into two types according to the direction in which the mountains circulate: yang dragon-mountains circling clockwise from the vein; yin dragon-mountains circling counterclockwise.

Another way to distinguish between Yin and Yang dragons is to judge according to the direction of water flow on both sides of the mountains. In nature, water always flows from high to low, and water flows from both sides of the mountains. If the water is on the left side of the origin , To discuss the dragon based on the direction of the veins, it is left water and right rotation, and the dragon vein is Yinlong; if the water flows on the right side of the vein, it is right water and left rotation, it is a positive rotation dragon, that is, a Yang dragon.
