Ask Feng Shui Daxian for help. The one in front of my house has a mirror on the back window, which can see my house. ...

Hehe, the first time I heard that willow trees were planted at home, the original good feng shui was destroyed. As the saying goes, "ghosts gather in Liu Xia", which would not have been unlucky, but the ghosts around the house at home have been vicious again and again. I suggest you cut down the willow tree on an auspicious day, burn some gold paper in the place where the willow tree is planted and tell all the ghosts to leave, and finally hang a gossip mirror on the lintel, so that all the evil spirits will disappear.

As for the mirror, it doesn't have much influence. If you really don't want to see it, you can discuss it with your neighbors and let them take it away. If so, then the Eight Diagrams Mirror will help you exorcise any evil spirits.

I hope my advice is helpful to you, and I wish you all the best.
