You should definitely look out for it. It's very enjoyable! I did some research, and yes there were many feminists and many writers such as Li Ruzhen who wrote Flowers in the Mirror, who was also a feminist such as Ibsen. I'm not sure if it was the first of it's kind, because there were many feminists during this time period that voiced their opinions about gender equality, but seeing as there were people who enjoyed this piece, I'm sure there were enough people that it became a classic.
