Why is the phenomenon of son preference serious in China?

The feudal ideology in the old society, the more backward it is, the more serious it is.

Mainly because of the physiological relationship, men are always better than women. As the name implies, a man is "He Li". Even if they have no skills, they can still contribute to this field. And women, because they are not as powerful as men, have their period every month, accidentally get pregnant, and even be demoted to a machine for babies.

My grandfather is a man who prefers boys to girls. My father, uncle and uncle all have daughters, while my aunts all have sons, which makes my grandfather very angry. In a word, those old-fashioned people who prefer boys to girls will be punished sooner or later, and they will have no children or daughters.
