Because in ancient times, it was generally believed that it was the best age for a woman to get married when she was thirteen or fourteen years old. At this time, women were almost developed and could get married, and the population demand in ancient times was still very large. All kinds of labor and wars needed a large number of people as support, so many ancient women were regarded as fertility tools. If they got married earlier, they might have more offspring.

In fact, I think it's also because people in ancient times didn't pay much attention to women. They thought that women are virtuous without talents. As a woman, they don't need to be able to do great things. Marriage is the most important thing in their lives. They must find a good husband after being instilled by their families from birth. It can be said that they are ready to get married from birth.

When a woman reaches the age of 13 or 14, her body organs are basically mature. Many ancient women will start looking for their sweetheart at this time, usually through the introduction of matchmakers. Once they find the object they are satisfied with, men will begin to prepare for the bride price and propose marriage to the woman's house. What women have to do is wait for news at home and then marry themselves beautifully.

In ancient times, there were basically conscripts every year, and the average life expectancy of the ancient population was very short. If we didn't get married earlier, the population would be far from the requirements at that time, and ancient families were generally proud of the prosperity of their families. The larger the population of a family, the happier the elders would be, and the daughters-in-law would feel that they had fulfilled their mission and continued the incense for their husbands, which was already a great contribution to ancient women.
