The story of two young Yue opera actors and actresses in the Republic of China. It is a fanfic about sisters on the Yue Opera stage, but it doesn't matter if you haven't seen the show. You can read it as an original novel.
It involves a lot of content and lyrics of the Yue Opera Butterfly Lovers, and Butterfly Lovers is a clue that runs through the whole text.
Concept: Two Shuangs in Yue Opera who depend on each other for life during the Republic of China
