1. Be reasonable first. If their family is to ward off evil spirits or something, you can make sense first and say that the charm of your family is not directed at my family. If you want to ward off evil spirits, please stick it in your own home, not in other people's homes.
2. Stick a mirror on your door to reflect these evil techniques back. Many residents around the hospital do this. They put mirrors on their doors.
3. finally, it's really impossible. Call the police and explain the situation to the police comrades. This is a propaganda of feudal superstition, and the police will let them win it.
