Is it good to hang a mirror at the entrance of the rural yard for feng shui?

It shouldn't be good, because I saw a folk taboo on the internet the other day, saying that mirrors should not be placed in the bedroom or opposite the door, otherwise the yin is too heavy and it is easy to attract ghosts. There is a bedroom in my house that is like that. As a result, I always feel that someone in the room is watching me, always flustered and upset. Better tear it down and find another place.

Not ideal. Mirrors have a reflective effect. Put a mirror in front of the door, and all the good luck that comes in is shot out by the anti-Dan flower, which is not conducive to seeking wealth.

It's okay to put it aside.
