In addition to some traditional factors, there was also a point that the education of girls was very strict at that time, and the social system at that time was patriarchal, so there were some disadvantages. Girls will be shy, and they will be shy when eating or dressing. Take eating alone. As a girl, she won't eat whatever she wants, but after all, the elders can take her turn. This can also be said to be a literacy that girls had to learn at that time.
2, that is, the material base at that time was generally very low, and it was impossible to eat whatever big fish and big meat wanted as it is now. I believe that many people will say at this time that there should be no shortage of wine and meat in large families in ancient times, and they all ate casually and wasted casually. Why is the good girl so well nourished and so thin after irregular exercise? Nowadays, many girls are very fat. If everyone thinks so, it's all wet. At that time, even the emperor's son of heaven saved food, what's more, only a large family would waste food?
3, that is, the life of ancient people was very regular. Most women did a lot of housework at home or embroidered clothes at home. There were not so many night entertainment activities in ancient times, and they were not developed. Therefore, their lives are very regular, and what they do at any time, especially women, don't stay up at all, and they are basically lovers and teachers. In ancient times, if a woman could not do housework, others would laugh to death, so this is a skill that must be mastered in ancient times.
