Why do China people insist on having sons?

In the feudal history of China for thousands of years, people thought that men were masters. Today, although they have been open-minded for so long, many traditional customs and habits still exist, including many commemorative activities to celebrate the birth of boys in many places. Therefore, many people still think that giving birth to a boy can honor the ancestors in order to save face. There are also people in China who are used to taking the man's surname regardless of whether they give birth to boys or girls, so they all think that girls give birth to children for others, and their daughters live with the man after they get married, and their parents also live with their sons. Today, these things have not changed, so women are actually suffering. As parents, of course, I don't want to suffer so much after giving birth to my daughter. They really feel that they won't leave themselves to live together when they have a son, and they rarely see them when they have a daughter. Then who doesn't want to have a son?
