In Peking opera and historical drama,
铡 evokes Lord Bao (
包拯, 999-1062) — the legendary upright magistrate of Kaifeng who, by tradition, was authorized to execute three classes of criminal on the spot using three named guillotines:
龙头铡 (dragon-head, for nobles),
虎头铡 (tiger-head, for officials),
狗头铡 (dog-head, for commoners). The opera 《
铡美案》 dramatizing the execution of Chen Shimei is a canonical piece.
