Is there anyone who knows Feng Shui? There is a mirror opposite my house. How to solve it simply without hanging a mirror? I just want this not to hurt harmony.

It's no use hanging an ordinary SLR at your door. Only people who don't understand feng shui will do this. Don't hang anything outside the house to avoid disharmony in the neighborhood. In your room, hang Five Blessingg gourd (without gossip pattern) on the wall above the entrance door, put down a set of five emperors' money, and put a nine-turn Qinglong Gan Kun Ding at the entrance, which will block evil spirits and attract all the wealth to the opposite side of the door.
