《论衡·卷四·书虚篇》
因为季子以吴国君王争权夺利的 吴之乱 为可耻，所以吴公子们想立他作为君主，他始终不肯接受，便离开京都去延陵，终身不回，廉洁谦让的操行始终如一。
夫季子耻吴之乱，吴欲共立以为主，终不肯受，去之延陵，终身不还，廉让之行，终始若一。
Because Jizi considered the disturbance in Wu — Wu Unrest in which the lords of the state of Wu fought for power — to be shameful, when the lords of the state of Wu wanted to establish him as their lord, he steadfastly refused. He left the capital city for Yanling and never returned. He remained incorruptible and self-effacing throughout his life.
