《元史·本纪·卷三十二》
 我伟大的太祖皇帝始造基业，世祖皇帝统一天下，建立规定的制度，以划一世代相承的皇统，宗室亲王各自接受分封之地，不敢妄生觊觎之心，这是子孙万代共同遵守的、不可改变的成规。
洪惟我太祖皇帝混一海宇，爰立定制，以一统绪，宗亲各受分地，勿敢妄生觊觎，此不易之成规，万世所共守者也。
My great grandfather, Emperor Taizu, first established the foundation, and Emperor Shizu unified the world and established a regular system to delineate the imperial lineage to be passed down through the generations. The clan princes each accepted their fiefdoms and did not dare to covet them presumptuously. This is an unbreakable rule that has been observed by all descendants for generations.
