There is an allusion that goes, Xi Shi, known for her peerless beauty, was beset by some sort of heart trouble, so she was often seen knitting her brow with hand on her chest. Now there was an ugly woman in the neighborhood, who one day saw Xi Shi in the village. In admiration, she returned home and determined to imitate Xi Shi’s way of walking and mannerisms. Yet, this oly increased her ugliness. Every time, she walked out, the rich would shut their doors tight, while the poor with their wives and children would avoid her and quickly turn their steps away. That woman mistook frowning for something invariably beautiful, and was unware that it only adds beauty to a real beauty. Now the allusion is used to satirize the blind imitation with ludicrous effect.
