《后汉书·列传·党锢列传》
张让向皇帝诉冤，诏召李膺入殿，皇上亲到廊上，责问李膺为什么不先请示就施行死刑。
让诉冤于帝，诏膺八殿，御亲临轩，诘以不先请便加诛辟之意。
Zhang Rang made an appeal to the emperor for justice, and the emperor summoned Li Ying to the throne room. The emperor came to the corridor and asked Li Ying why he had to carry out the death sentence without making a request beforehand.
