《元史·列传·卷六十二》
今大兄在北方，太后被迁居外地，内心也不舒畅，殿下当顺着太后的意思，使她老人家高兴些，这就尽了孝悌之心。 
今大兄在朔方，大母有居外之忧，殿下当迎奉意旨以娱乐之，则孝悌之道皆得矣。 
"Now that my elder brother is in the north and the queen mother has been moved away, my heart is not at ease. Your Highness should follow the queen mother's wishes and make her happy. This is the way to fulfill filial piety and fraternal love."
