《资治通鉴·唐纪·唐纪十一》
太宗说： 割地以分封功勋大臣，是古今的通义，朕的意思是想让你的后代，辅佐朕的子孙，共同传之久远；然而你们却多次上言充满怨言，难道是朕强迫给你们土地吗？ 
上曰： 割地以封功臣，古今通义，意欲公之后嗣，辅朕子孙，共传永久；而公等乃复发言怨望，朕岂强公等以茅土邪！ 
Emperor Taizong said: “Giving a fiefdom to divide the land to meritorious officials, that is the common sense of ancient and modern times; what I mean is to let your descendants assist my children and grandchildren, so that they can pass it down for a long time; however, you have complained many times, is it because I forced you to take the land?”
