《新唐书·列传·卷一百四十五》
如今男生兄弟相斗，男生当我的向导，国内虚实，我已尽知；再加上将帅忠心，士兵效力，所以臣说必平。
今男生兄弟阋很，为我乡导，虏之情伪，我尽知之，将忠士力，臣故曰必克。
"Now that the Xian brothers are fighting each other, Xian Jian is my guide, I know everything about the strengths and weaknesses of Goryeo, plus the generals are loyal and the soldiers are valiant, so I say that they are sure to be conquered."
