Nail is the formation of Shaqi. If the other party has gossip about concave mirror, it is to gather Shaqi with concave mirror and reflect it to your home. You can hang a gossip convex mirror and a bronze bell in front of your house. If you want to be tough on each other, hang a bronze lion bite sword. Then put a doorkeeper on the gate, go to the Buddhist supplies store and ask a great compassion mantra to hang at the gate. I believe that the power of the great compassion mantra can reduce all suffocation and protect the house from evil spirits.
Nailing the gate Feng Shui says that "the road rushes against evil" is a terrible evil. If the nail is placed above the door of the road, people's life on the road will not be smooth, which will lead to disaster. If the gate at the door happens to be in a hurry, it is probably the image of a murderer. This door is not suitable for elevators. Theoretically, it is called turning on the elevator, which is also a very unlucky ShaQi at home. The opening is the door facing the elevator door.
