《新唐书·列传·卷二十一》
太宗对群臣说 ：我根据各位功绩，量定封爵食邑，恐不尽能妥当，不必忌讳，各位都可说给我听。 
帝顾群臣曰： 朕论公等功，定封邑，恐不能尽，当无有讳，各为朕言之。 
Taizong said to the ministers: I, based on the merits of everyone, grant you ranks, titles and rewards, in fear of not being able to be accurate or appropriate. Do not refrain from expressing your opinion. You may all express your views to me.
