Why have men been afraid of their wives since ancient times in China?

It should be that since the founding of New China, men in China began to be afraid of their wives. In ancient times, few people were afraid of their wives. Because men can divorce their wives and women can't, my grandfather has been bullying my grandmother. You can't eat until you move the chopsticks nest. Guests are always beaten when they refuse to serve. I heard that this is the case in most cases.
