《隋书·列传·卷二十四》
到了玄武门，他假装上奏说： 我突然中了邪，命在旦夕，请得以与皇上当面辞别，我死而无憾。 
至玄武门，诡奏曰： 臣卒中恶，命县俄顷，请得面辞，死无所恨。 
When he reached Xuanwu Gate, he pretended to be an imperial edict and said: "I suddenly suffered from an evil spirit, and my life is in danger. I hope to be able to say goodbye to the emperor in person. I have no regrets in death."
