I think there may be a misunderstanding in the topic, that is, ancient women are really the same as modern slogans, and women can hold up half the sky. This was impossible in ancient times. Even looking forward and backward, we can know why the ratio of successful women to successful men has been so different for 5 thousand years.
Qinhuai Bayan is talented and beautiful, but what is their household registration? They are definitely not ordinary people. I guess they belong to slaves. Although prostitutes were separated in ancient times, although they were prostitutes, they were by no means ordinary household registration.
So, even if you can't change your household registration, what ability do you need to eat and earn money to support yourself?
In the late Ming and early Qing dynasties, the country was in turmoil and the people were in a precarious situation. What will they do? Which of these things can make them go out independently without being hurt? It is impossible to sing backyard flowers across the river. Although brothels have a bad reputation, they can at least provide protection for these weak women.
In that era of hunger and cold, it is a good thing to be a beautiful girl in Qinhuai in a brothel. You can have food and clothing without worrying about being beheaded or robbed tomorrow. Why do you have to think hard about leaving the brothel?
Finally, we can get more information when we welcome them in brothels, which is why they are smarter than ordinary women. How can a woman who can't go out have such knowledge?
So I think Qinhuai Bayan and brothel are closely related, and they complement each other, so that everyone can achieve each other. Therefore, no matter how talented and beautiful she is, and without a strong background, the possibility that a woman wants to achieve something in that era is negative.
