Hanging method of mirror on gate

This place is called magic mirror, which has two functions: one is to prevent unclean things from entering the house; The second is to pass on the bad luck at home to another family. Therefore, the hanging time should be when the sun is heaviest, preferably at noon, and it must be hung when the sun is dazzling, so that the mirror can absorb the most of the sun's gas and block bad luck at night when the yin is heavy. The mirror must be hung in the center right above the gatehouse, and it must be facing a family, otherwise the bad luck cannot be transferred. However, it is not very kind to do so, and it will cause conflicts after being discovered by neighbors. I hope I can give you some reference.
