Duke Wen of Zhao was so fond of dueling that he kept three thousand swordplayers at his residence. Day and night, they competed against another to entertain the duke. Though more than a hundred were killed every year, the duke’s fondness for swordplay never faded. Three years went by and as the state of Zhao declined, other states plotted to attack it.
Li, the crown prince, was greatly worried. He consulted his officials, promising, “Whoever can persuade the duke to give up swordplay will be rewarded with one thousand pieces of gold.” The officials all agreed, “Only Zhuangzi can accomplish the mission.”
