Second, what is the emphasis on the placement of mirrors?
In home geomantic omen, every direction has its aura and action, so the role of the mirror in each direction will be different. For example, the southwest of home belongs to the earth, and there are negative import and export aura such as Yin Qi and villain. Therefore, if you put a mirror in the southwest, it is easy to attract villains. The mirror placed in the southwest of the bedroom is easy to cause nightmares and bad luck.
