《资治通鉴·唐纪·唐纪五十六》
裴度奏请将各处监督战阵的中使全部罢除，各将领这才得以专力办理军中事务，在作战中经常取胜。
度悉奏去之，诸将始得专军事，战多有功。
Pei Du submitted a memorial asking to remove all the Zhongshi who supervised the battle arrays in various places. Only then did the generals have the chance to focus on military affairs, and were able to win frequently in battle.
