What should people do when they meet ghosts?

It is said that people have three fires, one on their heads and the other on their shoulders. If you walk at night and hear someone calling your name, don't look back, because once you turn back, the fire on your shoulders will go out and ghosts will have an opportunity. When you feel that you have met him, you can scold him and scold him loudly. I heard it would scare him away.
