Where did the custom of "son preference" come from, and why did you have this idea?

1. Men are naturally superior to women in physical strength and other physiological aspects. In the early days of human evolution, stronger physical strength meant more food sources and more chances of survival in tribal wars.

2. Economy. Humans have formed a mindset in evolution: men have a natural advantage in sociality. Because men's physical strength is better than women's, they can engage in farming better and get more pay in ancient times. In the case of limited or even lack of resources, it also constitutes the economic reason why parents prefer sons to daughters.

Extended data:

Preference for boys is an unequal concept between men and women in society. It attaches importance to men's rights and interests, defines women as men's subordinates, and restricts women's opportunities to develop their personal talents and personal freedom.

This concept is common in male-dominated society, often accompanied by the concept of male superiority and gender division of labor. The concept of son preference will also affect parents' willingness to have boys and girls. For example, Oracle Bone Inscriptions in ancient China thought it was good to have boys, but not good to have girls.

Some languages also show a preference for boys over girls. For example, in Chinese, "women's opinion" refers to the opinions of people without knowledge, and "women's benevolence" refers to kindness that does not take care of the overall situation and contains the meaning of belittling women's intelligence.
