《后汉书·列传·杜栾刘李刘谢列传》
我诚恳陈情，说的话没有值得皇上采择的地方，只怕因此触忤皇上，不胜惶恐。帝逝世，大将军窦武想大杀宦官，引用刘瑜为侍中，又用侍中尹勋为尚书令，共同谋划。
拜为议郎。及帝崩，大将军窦武欲大诛宦官，乃引瑜为侍中，又以侍中尹勋为尚书令，共同谋画。
I sincerely express my feelings, even though the words I say are not suitable for the Emperor to adopt, I am afraid that this will offend the Emperor, and I am very apprehensive. After the Emperor passed away, General-in-Chief Dou Wu wanted to kill a large number of eunuchs, so he summoned Liu Yu as the Imperial Attendant, and also appointed Imperial Attendant Yin Xun as the Minister of the Imperial Secretariat, in order to plan together.
