《晋书·列传·第四章》
皇帝打算让羊祜卧床监护诸将，茎拈说： 攻取县厘不一定要我亲自参与，平定之时，当使皇上费心。
帝欲使祜卧护诸将，祜曰： 取吴不必须臣自行，但既平之后，当劳圣虑耳。
The emperor planned to let Yang Hu supervise the generals in bed, but Yan Yan said: "It is not necessary for me to participate in the capture of Xiacai personally, and when it is pacified, the emperor should worry about it."
