Unjust relatives and creditors will pretend to be buddhas and bodhisattvas to lead people to death. Do they also pretend to be teachers or Guanyin? How can we be sure that it is the Buddha?

When you hear the voice behind you, you invite the caller to talk face to face. Although the caller can pretend to be a teacher or other bodhisattva, his eyes can't pretend. Look him in the eye and concentrate on the Buddhist scriptures or spells you usually recite, and he will run away. If you are a teacher or avalokitesvara, he can stand the test, so you can go with him.

I hope I can help you, please adopt it.
