There are two kinds, one is predestined relationship, and you saved him and helped him in your previous life or this life. This is good karma. He came to repay the kindness, not to help your family; The other is the sentient beings who have been hurt and eaten by your family. He came to your house to make trouble and harm your house, just to get back at him. When you encounter such a thing, you should repent with him, sincerely repent, and then recite the Buddha and the scriptures to cross him over and let him live a good life and a paradise. This is the best way. Of course, no matter how you repay your kindness and complain, you are all six divisions in the wheel of karma, and you can't escape life and death. It is still very safe to survive in the Elysium. If you sincerely read Amitabha, you will be born. Well, that's what happened. Most of the lives that are not in the same dimension as us belong to ghost creatures.
