What are the three evil spirits?

Three evil spirits are commonly used terms in geomantic omen, which come from the three-in-one game and the five-element theory. The three evils consist of robbery, disaster and age. And the three evil positions, that is, the position that conflicts with the three-in-one and five-element bureau every year.

At noon, the fire broke out in the south, and the north (Hai Zi Chou) rushed for it, which was the three evil spirits (Hai is a robbery, Zi is a disaster, and Ugliness is also called the tomb evil spirit). Shen enters the water bureau, the north is full of water, and the south (noon) rushes for it, which is the three evil spirits (noon evil spirits, noon evil spirits, not old evil spirits).

Haimao is not in the wooden bureau, Muwang is in the east, and the west (Shen) is the rush, which is the three evil spirits (Shen is a robbery, unitary is a disaster, and unitary is an old evil spirit). In the ugly alloy bureau, in the west, the East (Chen) is the main force, that is, the three evil spirits (Yin is the evil spirit, Mao is the evil spirit, and Chen is the old evil spirit). According to the rhyme, it is "noon, north evil, Shen Chenzi evil, Hai Mao did not kill the west, ugly killed the east."
