In ancient times, a wife could rent it. Why is it so serious not to have a son after renting it?

Because the traditional thinking of son preference is deeply rooted since ancient times, women have no status and are only tools for fertility. In ancient times, polygamy was practiced, and men with a little prestige and financial resources were all daughters-in-law. If they can't have sons, not only their husbands and mother-in-law look down on them, but also their wives and concubines look down on them and suppress them everywhere. Therefore, leasing has no human rights status and needs the husband's family to drive it.

In ancient China, the idea of valuing agriculture over commerce prevailed. Men usually go out to work or go shopping, while women usually stay at home and don't need to do farm work at home. A wealthy family is polygamous, and the husband earns money alone and the whole family uses it. Therefore, men are the pillars of the family. Women in ordinary families don't need to go out to earn money. Otherwise, men will lose face outside. Will be looked down upon by the powerful outside.

Women usually take care of children at home, and sometimes they don't have to cook. They need domestic servants to prepare and wait for dinner. Therefore, as long as a woman gives birth to a son, her position in the family is very high, that is, the mother's dependence on her child. If a woman can't have a son, she will be looked down upon by her husband's family and even divorced. Some women's families are very powerful, and husbands can't divorce their wives, so they need to give their parents face. But in order to carry on the family line, their parents will also agree to rent a house or buy a concubine to have a son.

If a rented or bought concubine can't give birth to a son, the lighter will give up, and the heavier will be beaten and scolded by her husband at home. Her mother-in-law bullies you all day and has no position at home, and her husband's family will not treat you like a person.
