When a tiger goes to nave, his family is ruined. What does the tiger mean here?

Literally, when a tiger comes to his hall, it will eat all the people in the family and ruin the family. The tiger is not in the forest or the zoo, so it is impossible to come to other people's homes. Even in relatively remote rural areas, there will be no tigers, so the tigers here are definitely not tigers, but such proverbs have indeed been handed down, so some people have begun to give it new meanings. A few days ago, I read a report that the tiger in this sentence refers to a bad woman, which means that some people in the countryside accidentally married a lazy woman and hung upside down.
