《元史·列传·卷六十二》
是年五月，武宗即位。有人对武宗说 ：内难初定之时，李孟曾劝皇弟自己登基，如果依照孟的话，哪有今日！ 
夏五月，武宗即位，有言于帝曰： 内难之初定也，李孟尝劝皇弟以自取，如彼言，岂有今日！ 
In May of that year, Emperor Wuzong ascended the throne. Someone said to him: When the internal strife had just been quelled, Li Meng persuaded your imperial brother to claim the throne himself. Had we followed his advice, today would never have come!
