Can feng shui compass be hung on the gate to kill the mirror opposite the door?

Mirrors will reflect bad things to your home. Generally speaking, they should not be used in modern residential areas of cities. It is best to use something that can dissolve the qi, such as a feng shui compass or long-term five emperors' money. The principle is to resolve hostility rather than reflection, so that the grievances of the two families will not rise, but will be resolved smoothly and harmoniously.
