《元史·本纪·卷一》
乌古孙仲端乞怜哀告，太祖说： 想到你大老远跑来，河朔地区既然已经归我所有，那就把关西还没有攻下来的那几城割让给我罢！让你主子当河南王，再不要违抗我了。 
仲端乞哀，帝曰： 念汝远来，河朔既为我有，关西数城未下者，其割付我，令汝主为河南王，勿复违也。 
Wugusunzongduan begged for mercy and pleaded, and Taizu said: Seeing as you travelled so far, and the Hebei region already belongs to me, then cede to me the several cities in Guanzhong that have not yet been captured! Let your Lord be the King of Henan, and never again defy me.
