《后汉书·列传·宦者列传》
于是帝叫了单超、左忄官到他的室内，说： 梁将军兄弟专权朝廷，压迫威胁内外，公卿以下都跟着他们跑，现在我想诛杀他们，常侍的意思怎么样？ 
于是帝呼超、悺入室，谓曰： 梁将军兄弟专固国朝，迫胁外内，公卿以下从其风旨。今欲诛之，于常侍意何如？ 
So the emperor called Shan Chao and Zuo Xin to his desk and said: The Liang Family General holds the court in his hands and intimidates people inside and outside the palace. All the civil and military officials follow him. Now I want to execute them. What do you gentlemen think should be done?
