Ancient boys were called "Tianding" and girls were called "Tiankou"? Why is this?

In the old feudal society, the status of men and women has always been that men are superior to women, and men and women will have different opinions to distinguish the same event to show that men are superior to women. People in ancient times liked to have boys, because it was an important event to carry on the family line. Anyone who keeps giving birth to daughters but not boys will be laughed at by everyone, and even some people are superstitious and cursed. So in ancient times, there was a custom of delivering babies. When the matchmaker gives birth to a boy, he will be overjoyed to go out and tell his family that he will get a reward for adding a man. If the midwife is a girl, she will only calmly say that she added a bite and won't get extra rewards. What is the reason for this difference?

1, men are the pillars of the family. From the analysis of the T-shape itself, it looks like a man holding up a sky with one hand, which vividly shows the great power that ancient men contributed to the family's livelihood, so men will become men when they can work, such as dinking and able-bodied men. It shows that men have a higher labor force and occupy a dominant position in the labor society on which human beings depend, so their natural status is higher and their appellation is different from that of women.

2. Women do housework at home and help men do housework. Women's physical function is weaker than men's, and there are special physiological reasons that make women unable to compare with men in labor. They only do textiles, cook and do all kinds of housework at home, so that men who have worked hard for a day can have a comfortable rest environment at home. When they have children, they will become good wives and mothers. In ancient society, women were very important in maintaining their lives, but they still could not compete with men.

3. The man explained the reception and the woman got married and left. This is the national culture of China, which has been passed down for thousands of years. Men will get married and have children when they grow up, and women will find a good family when they grow up. When they get married, they will become members of the man's family and enter the family tree. Therefore, there is a girl who just eats with her mouth open, and a boy is the future master of the family.
