What should be avoided in the robbery, disaster and moon evil in Lao Huang Li Tong's books?

Robbery, disaster and moon evil are referred to as three evil spirits for short, three evil spirits are fierce, and three evil spirits are especially unfavorable and taboo.

For example, 20 15, the three hazards are in the west, northwest and southwest, and it is not suitable to break ground. Otherwise, commit murder.

20 16, the three evils are in the south, south-southeast and south-southwest respectively.

I hope there is fate.
