2o 15 Where is the bullfighting evil spirit?

According to Kong Xuan geomantic omen, the evil spirit of bullfighting is a combination of two black stars and three blue stars. If these two stars appear in the same position, they will become the evil spirits of bullfighting. But their appearance does not have a fixed position every year, but depends on the sitting posture of each villa. The seating position determines the flight situation of Shanxing and Xiangxing. Different sitting directions have different flight conditions of mountain stars and directional stars. This situation is constant in every movement, but it changes every year.
