《旧唐书·列传·卷一百二十六》
魏抃进奏说： 御史台是维护朝纲法纪的地方，不适合与管理钱财的官职交叉兼任，请求免去御史中丞职务，专一治理户部公务。 
抃奏曰： 御史台纪纲之地，不宜与泉货吏杂处，乞罢中司，专综户部公事。 
Wei Bo stated in the memorial: The Censorate is a place where the laws and regulations of the court are upheld, it is not suitable to concurrently hold a position that manages money, I request to be relieved of the position of Censor-in-Chief and focus on the official business of the Ministry of Revenue.
