Jiao Sifang is actually an official prostitute, who can not only perform for the court, but also serve various officials, in short, a prostitute. This title changed in the Ming Dynasty. Because officials' wives and daughters are not ordinary people, their living conditions are superior, their bodies are well maintained, and more importantly, they are proficient in piano, chess, calligraphy and painting, poetry and songs, so they are very popular among literati and dignitaries. As far as the teaching workshop is concerned, these women are very popular, because they don't need to spend money at all, just need to provide food, clothing, housing and transportation, and all skills don't need deliberate training. The teaching workshop is well aware of the huge profits here. For women who used to be group slaves, how to endure this identity change, the job responsibilities of the teaching workshop make them feel ashamed.
Most importantly, after entering the teaching workshop, you are a pariah, not even a citizen. This status was restricted in ancient times and was not respected. What's more, the descendants born from generation to generation have this identity, and it is difficult to get rid of it, let alone become an official in the imperial examination in the future. It's impossible. Therefore, the wives and daughters of these officials know very well that once they enter the teaching department, they will never be able to turn over.
In a word, Jiaofang is a place of shame, so any wife and daughter of an official with backbone will not set foot in Jiaofang.
