This is a convex mirror, which is used in Feng Shui to reflect some bad shapes and evil spirits to their home. I don’t know if the building near your house has horns or the real evil has affected them, which is why they hung up mirrors to block the evil. If it is facing your house like this, you can’t hang one to fight them. Feng Shui emphasizes rescuing the poor, rescuing those in distress, and living a harmonious life, without participating in fights or causing disputes or conflicts with neighbors.
It is only recommended that you place a taller jade unicorn plant to block evil spirits. It can not only green the house, but also ward off evil spirits. It can also ward off evil spirits and avoid doubts about fights.
Pictures of the plants are provided below. They are sold in most florists or flower farms.
Don’t use feng shui items that can cause fights with others: avoid using lions, unicorns, tridents, gossips, and mirrors. This will make conflicts bigger and bigger. If right and wrong become more and more serious, just put some plants there. Can be solved.
