《资治通鉴·唐纪·唐纪九》
起初，太宗令大臣们议论分封诸王的事，魏徵认为： 如果分封诸王建诸侯国，则卿大夫们都靠俸禄生活，必然导致大量征赋。
初，上令群臣议封建，魏征议以为： 若封建诸侯，则卿大夫咸资俸禄，必致厚敛。
At first, Emperor Taizong ordered the ministers to discuss the division of the feudal kings. Wei Zheng believed that if the feudal kings were enfeoffed to build vassal states, then the ministers and doctors would all rely on their salaries to live, which would inevitably lead to a large amount of taxation.
