King Zhuang of Chu gave his ministers a feast. Late in the evening, when all were drunk, the candles went out. In the dark a man pulled at the dress of one of the king’s women. She tore the tassel off his hat and told the king: “Bring the light and look for the man without a tassel.”
The king said: “I gave them wine and made them drunk. Why should I display a woman’s virtue and shame an officer?” He ordered: “Whoever drinks with me tonight and does not tear off his tassel has not enjoyed himself.” More than a hundred men tore off their tassels before the lights came back.
Three years later, in a battle against Jin, one officer always fought in front. He told the king that he was the man whose tassel had been torn off. The story is in Liu Xiang’s Garden of Stories (说苑).
