《周书·列传·卷二十二》
于是他写了一些匿名信分贴在官府门上，信中说： 我们合伙抢劫胡家，人员混杂，最终恐怕都要泄露出来。
乃作匿名书多牓官门曰： 我等共劫胡家，徒侣混杂，终恐泄露。
So he wrote some anonymous letters and posted them on the door of the government office, saying: We robbed the Hu family together, and the people were mixed, and I'm afraid that we will all be exposed in the end.
