《宋史·列传·卷一百四十二》
四年后，孝宗到白石举行阅兵大典，看到士兵都年轻力壮，很有战斗力，对手下大臣说 ：这都是虞允文实行优胜劣汰，对士兵进行裁减淘汰的结果。 不久下诏追赠虞允文太傅，赐谥 忠肃 。
后四年，上幸白石大阅，见军皆少壮，谓辅臣曰： 虞允文行沙汰之效也。 寻诏赠太傅，赐谥忠肃。
Four years later, Xiaozong visited Baishi to hold a grand review of the troops. Seeing that the soldiers were all young and vigorous and very capable in combat, he said to his ministers: "This is all due to Yu Yunwen's implementation of the survival of the fittest and the elimination of the inferior, and to his reduction and elimination of soldiers." Soon afterwards, he issued an edict posthumously conferring on Yu Yunwen the title of Grand Tutor and granting him the posthumous name "Chungsu."
