Why did the ancient monks and nuns feel unlucky? For example, in A Dream of Red Mansions, the elders did not let Xichun become a Taoist?

Monks and nuns are monks, who stay in monasteries all the year round without contact with the outside world, so once they go out, they are easily followed by people in the street, especially nuns, who are more likely to become the targets of all kinds of perverts. So in order to protect monks, some wise men came up with such a way.

Think about it, if you are told directly that you can't bully monks, the warning will definitely not tell you directly that "monks are unlucky, don't provoke" and "nuns have infectious diseases" These warnings are strong.

Smart people naturally understand the truth, but more people are ordinary people. They don't understand, so they believe it.
