Immortals appear in fairy tales, which we can't see in real life, at least for the time being. Then why do people worship the weasel as Wong Tai Sin? What do you think? You know, the image of the weasel is actually not good. The weasel has been in the business of stealing chickens and dogs.
In my opinion, the weasel became Wong Tai Sin because the people were poor at that time, and they needed a belief to support them to survive. Believing in ghosts and gods is a good choice. The influence of supernatural beings on people's spirit is actually only a psychological effect of people. If a person has psychological problems, his body will not be healthy, and then it will be manifested as the occurrence of diseases.
Some people think that they are sick because of what they recruit, and then they go to the master. Under the action of those so-called masters, the condition deteriorated step by step, missed the best treatment opportunity and eventually died. At this time, some people will say that their lives have been exhausted. If you are treated in a hospital, they will say that this is the black heart of the hospital. In fact, it is a natural phenomenon that we are sick. Everyone has a chance to get sick, just depending on whose immune system can successfully remove pathogens and cancer cells.
