Thousands of people have been killed unjustly. How horrible was the "evocation case" during the Qianlong period?

In ancient times, when someone was frightened, his family would ask the warlock to summon his soul and calm him down. On the other hand, please ask the warlock to call other people's souls away, or you can curse others. During the Qianlong period, a stone bridge was being built in the town. A stonemason was invited from other places. When the stonemason was carving a pier, a farmer found him and gave him a piece of paper with his name written on it, so that the stonemason could stick it on the pier.

The stonemason didn't understand and asked him why he did it. The farmer said his nephew's name was on the paper. Seeing that he is old and weak, his nephew often abuses him to gain his wealth. So the farmer asked the Taoist for a spell. As long as the stonemason stuck it on the pier and then knocked it with a hammer, he could call out the nephew's soul and kill him.

The stonemason was very scared after hearing this. In a few words, the peasants were sent away and reported to the government. The government arrested farmers, and the means of harming people spread. There is a wave of soul calling all over the country, and there are various means. Some cut off other people's clothes and secretly call the soul, some call the soul through their nails, and some cut off other people's hair and secretly curse others.

Gan Long thinks that evocation is a trivial matter, and a haircut is a major matter. Cutting your hair may be an excuse to make a fuss about the remnants of the past. He immediately ordered that all the people involved in evocation be arrested and strictly investigated. Officials all over the country, in order to have political achievements, as long as someone reports, arrest people immediately, and many people are wronged and sent to prison. What I want to say is that superstition is not credible, so it needs scientific basis.
