《资治通鉴·晋纪·晋纪二十四》
王猛军令严明，部队秋毫无犯。他又简化法律，放宽政令，前燕的百姓安居乐业，都互相称颂说： 没想到今天又见到了太原王慕容恪！ 
号令严明，军无私犯，法简政宽，燕民各安其业，更相谓曰： 不图今日复见太原王！ 
Wang Meng enforced the strictest discipline, and his troops did not molest a single thing. He also simplified the laws and lightened the punishments. The people of Former Yan were glad, and they made a saying about him: "We never expected to see the like of King Mu'Rong Ke again in our day!"
