Why does pinching the middle finger hurt so much when fortune telling?

Pinch your fingers not to ward off evil spirits. If you can really ward off evil spirits, why can't you pinch your fingers when you don't ward off evil spirits? What's the difference between pinching fingers and not pinching fingers? -It hurts!

Pinching fingers is not used to ward off evil spirits, but someone is possessed by something dirty, and his original soul can't control his body. A person with "Buddhism" will wake up this person's fingers. Because pinching his fingers will make this person feel pain, so that his own spiritual strength can be aroused. As long as his own spiritual strength is stronger than the possessed dirty things, then the dirty things will leave. Pinch fingers are usually in the middle of the middle finger or ring finger, because pinching these two paragraphs will hurt.

At the same time, when you pinch your fingers, you should recite a spell. In addition to making people feel pain, they also need to recite incantations, and use the power of incantations and the spirit of people with laws to spread the power of incantations and the spirit of people with laws from their fingers to the whole body, and use the power of incantations and the spirit of people with laws to force dirty things out of the body.

Later this method was rumored to be wrong. At first, it was said that pinching fingers could be used on the ghost's upper body. In fact, the effect of ordinary people pinching his fingers is not very good, because of the lack of magic and "the spirit of law." Then he said that pinching fingers can ward off evil spirits, but he really didn't understand the original meaning of pinching fingers.
