《资治通鉴·晋纪·晋纪十四》
八月，明帝下诏征召郗鉴回京，中途经过姑孰，王敦与郗鉴议论西晋人物，王敦说： 乐广才能有限，考较他的实际作为，哪能胜过满奋呢！ 
八月，诏征鉴还，道经姑孰，敦与之论西朝人士，曰： 乐彦辅，短才耳。考其实，岂胜满武秋邪！ 
In August, Emperor Ming issued an imperial edict to summon Xi Jian back to the capital. Xi Jian passed by Gushu and discussed the figures of the Western Jin Dynasty with Wang Dun. Wang Dun said, "Le Guang's ability is limited. When we examine his actual achievements, how could he be better than Man Fen?"
