《资治通鉴·汉纪·汉纪二十一》
我们从遥远的地方到此，人马困乏已极，而粮草又快用完，恐怕连回程都不够用，请单于跟大臣们慎重考虑。 
兵来道远，人畜罢极，食度且尽，恐无以自还，愿单于与大臣审计策。 
"We have come from afar, and our men and horses are exhausted. Our food supplies are running low. I fear that we will not have enough to make the return journey. Please ask the Chanyu to consider this matter carefully with his ministers."
