The top evil spirit is the telephone poles, lampposts, trees and street signs you see in front of the door. Most people who commit crimes are not good for their health. Modern buildings are built very high, and the top evil spirit only works below five floors.
Solution: hang a convex lens, eight diagrams mirror or five emperors' money at the door. The convex mirror, like a turtle shell, has a reflective function. When something with evil spirit rushes in, the convex mirror can melt away the evil spirit. As the name implies, the Eight Diagrams Mirror is eight kinds of fields corresponding to eight kinds of images. Among them, the Taiji diagram condenses the information of the balance of the universe, which can play a role in resolving the influence of the transformation of the gas field and removing the unfavorable terrain on itself. The five emperors' ancient money can improve the efficacy of convex mirrors.
