Playing the zither wasn't something difficult for these ladies from prominent families, as they each received training in music, chess, calligraphy, and painting from a young age. Even concubines' daughters wouldn't fall behind unless a truly shameless stepmother deliberately tried to keep them down. Thus, when it came to talent, although skill levels might vary, they generally wouldn't be stage-shy.
