因为顾全武曾经当过和尚，秦裴便封上给顾全武的信函派人送去表示降服，顾全武大喜，召来各位将领当众打开信函，里面竟然是一卷佛经，顾全武十分羞恼，说： 秦裴不怕死到临头，还有什么功夫戏弄我！ 
全武尝为僧，裴封函纳款，全武喜，召诸将发函，乃佛经一卷，全武大惭，曰： 裴不忧死，何暇戏予！ 
Because Gu Quawu had once been a monk, Qin Pei sealed a letter to him and sent someone to deliver it to indicate his surrender; Gu Quawu was overjoyed; he summoned all the generals and opened the letter in front of all; unexpectedly, it was a roll of Buddhist sutras; Gu Quawu was very angry, saying, "Qin Pei is not afraid of death, what does he mean by making fun of me!"
