《新唐书·列传·卷一百四十六》
李靖攻击吐谷浑，赤辞带兵屯扎狼道峡抵抗王师，廊州刺史久且洛生想劝他归降，赤辞辞谢 浑的君主待我如腹心，我不认识别人。你快走开，免得弄脏我的刀 。
李靖击吐谷浑，赤辞屯狼道峡抗王师。廓州刺史久且洛生欲谕降之，辞曰： 浑主以腹心待我，不知其佗，若速去，且污吾刀。 
When Li Jing attacked the Tugu Hun, Chidi led an army and set up camp in Langdaoxia Gorge to resist the imperial army. Jiuchulosheng, the Lirangzhou Prefect, tried to persuade him to surrender, but Chidi declined by saying, “The Tugu Hun’s ruler treats me like his own flesh and blood—I do not know anyone else. You should go away quickly, to avoid dirtying my blade.”
