《旧唐书·列传·卷九十一》
城乡的官吏都由他自己任命设置，户籍不向政府登记，赋税不向朝廷交纳，虽然称为 藩臣 ，实际上并没有大臣的节操。
郡邑官吏，皆自署置。户版不籍于天府，税赋不入于朝廷，虽曰籓臣，实无臣节。
Officials in the city and the countryside were all appointed and installed by himself, households were not registered with the government and taxes were not paid to the court; although he was known as a "vassal", in reality he did not possess even the most minimal ethics of a minister.
