What is the fortune teller's consciousness to put peach branches on his body?

The fortune-teller said that there was evil in him, so he released peach branches. To ward off evil spirits. It may mean that you are not feeling well, and you didn't find anything wrong when you went to the hospital. But I'm really uncomfortable. Or where it hurts, it's medically called an epidemic. That is, exogenous evil. Maybe we should use the fortune teller's statement at this time, which may solve the problem. If you think going to the hospital won't have any effect. Then you might as well try his statement. It might really work.
