《资治通鉴·唐纪·唐纪五十五》
纵然神策军中也有果决勇猛的将领，得到命令便奔赴敌军，但是节度使无法使用刑杀的权力来控制他们。这些将领将节度使看作平等交往的人物，节度使支使他们前进或撤退时，他们不肯服从命令，这有什么益处呢？
纵有果锐之将，闻命奔赴，节度使无刑戮以相制之，相视平交，左右前却，莫肯用命，何所益乎！
Even though there were also decisive and brave generals in the Shence Army who rushed to the enemy after receiving the order, the Jiedushi had no way to control them with the power of punishment and killing. These generals regarded the Jiedushi as an equal, and when the Jiedushi ordered them to advance or retreat, they refused to obey orders. What would be the benefit of this?
