Compared with ancient times, modern women can choose books and other ways for pre-marital education, but in ancient times, materials were not so rich and ancient people's thoughts were feudal, so many times ancient people expressed something in a special way.
For ancient people, open-backed pants were not only clothes that children could wear, but also women in ancient times could wear them. Their basic functions are the same as those of children, so I won't go into details here. At this time, some people may ask, won't you feel embarrassed? The answer is of course yes, but ancient clothes are different from today's. Most of them are very old, even if they are worn, they are not easy to see.
Then why do you have to wear such embarrassing open-backed pants? This was very popular in the palace, but it later spread to the people.
Now they all say that they are free to fall in love, but in ancient times, most of the time, their marriages were arranged by their families. With luck, ancient lovers may meet before marriage, but this is a very small probability. Many of them have never met, and they will only meet on the day of their last wedding. Before that, there was not much communication, so at this time, two people just had the identity of husband and wife, but as for familiarity, there was no more.
So the ancients thought of a way. In order to avoid the embarrassment of the wedding day, the ancients put open-backed pants in the dowry, which can solve the problem of unfamiliar couples to a great extent, and can also deepen the feelings of two people, and at the same time, for convenience, they can better reproduce. After all, in ancient times, if a woman was infertile, she would be stigmatized to varying degrees, so she prepared such a dowry for her daughter when she got married.
