《资治通鉴·晋纪·晋纪二十八》
王穆劝谏张大豫说： 吕光粮食充足，城池坚固，武器精良，军队锋锐，威逼他于己不利，不如横扫岭西，训练军队积蓄粮食，然后再东进与他抗争，不用一年，就可以攻取吕光。 
王穆谏曰： 光粮丰城固，甲兵精锐，逼之非利；不如席卷岭西，砺兵积粟，然后东向与之争，不及期年，光可取也。 
Wang Mu persuaded Zhang Dayu, saying: "Lv Guang has sufficient food, strong cities, sophisticated weapons, and sharp troops. It is not good for him to coerce him. It is better to sweep Lingxi, train troops, stock up on food, and then go east to fight against him. It will take less than a year to capture Lv Guang."
