What does it mean to refute marriage evil spirit?

Refuting marriage is a superstitious saying, which means that there are obstacles on the road to marriage, which is not suitable for marriage, and marriage will bring disaster.

As soon as you get married, there will be all kinds of problems that will affect you, make you unable to get married, or make you break up. We must use superstitious methods such as jumping into the sky to get rid of the evil spirits of refuting marriage before we can get married.
