《太平广记·卷一百五十四·定数九》
有人解释说： 打麦就是割麦子的时候， 麦打 是暗中袭击的意思， 三三三 是说六月三日， 舞完了 是说武元衡完了。 
解者曰： 以为打麦刈麦时也，麦打谓暗中突击也，三三三谓六月三日也，舞了谓元衡卒也。
Someone explained that: Beating the wheat means reaping, Beating the wheat secretly means a surprise attack, Three three three means June 3rd, The dance is over, means Wu Yuanheng is finished.
