The fortune teller said that my mother's Tang Yin was black and haunted, and she would die. What should I do? I was scared.

Do you believe what he said? I'm afraid you will meet a charlatan. Some truly academic people generally don't say such things.

You can take your mother to some famous temples to burn incense. If there is, there will be some abnormal reactions. In addition, if there is a master in the temple, he will definitely visit.

In your case, you can find those temples, and the direction of the door is west, which is safer.
