What's the function of hanging a gossip mirror at home? How to resolve the feng shui of the opposite door?

Mirrors are reflectors in principle, so they can ward off evil spirits and decontaminate in geomantic omen. For example, the eight diagrams mirror hung at the door to block evil spirits. If it is a whole piece of non-reflective art glass, it can be hung, but after the mirror goes up, it will be blocked out, whether it is auspicious or unlucky. So it is generally not recommended to hang up. But the feng shui of each family is different, and the layout of each door is different. If you value this, you have to find someone who knows how to do it. If you are only in the eyes of the public, read more relevant articles on the Internet and make a decision yourself. I hope I can help you.
