《晋书·列传·第十五章》
尚书杜友、廷尉刘良都是忠于职守的人，知道任恺被买充压制，想要替他申辩，所以迟迟不判，于是任恺和杜友、刘良都免官。
尚书杜友、廷尉刘良并忠公士也，知恺为充所抑，欲申理之，故迟留而未断，以是恺及友、良皆免官。
Shangshu, Du You, and Tingwei, Liu Liang, were loyal to their duties and knew that Ren Kai was being suppressed by Jia Chong. They wanted to defend him. Therefore, they delayed the judgment, and Ren Kai, Du You, and Liu Liang were all dismissed.
