How does Christianity view such persons who are Xianpo(s)?

I live in China, and there is a kind of person called Xianpo here. The Xianpo can talk to the dead soul, and the soul can tell the Xainpo what he saw. One day, I told the Xianpo that I met a woman, so the Xianpo said to me the following things: The Xianpo said: - She has neither promised nor refused to fall in love with me now. - She is my classmate. - She is a little shorter than me. - She is a outsider. - She has a good figure, an oval face, and her face is white and beautiful. - I miss her so I can't sleep at night. - She has long hair. I met this woman recently. The Xianpo hasn't seen her, but she can describe her figure and appearance very accurately. The Xianpo also said that some people have mental disorders because their souls have entered hell and married female souls. How does Christianity view such Xianpo? What is the biblical basis of this phenomenon? My respond： 1. Even if all Jesus encountered were evil souls, it cannot be said that all those with this ability are evil souls. It is unreasonable to say that others are evil just because of this ability. 2. I live in a place where I don't know what Jesus is, and I am more curious about Jesus.
