《资治通鉴·晋纪·晋纪二十一》
苻雄虽然具有辅国元勋的身份，权力近于君主，然而却态度谦恭，泛爱民众，遵奉法度，所以苻健非常看重他，经常说： 苻雄是我的周公。 
雄以佐命无勋，位兼将相，权侔人主，而谦恭泛爱，遵奉法度，故健重之，常曰： 元才，吾之周公也。 
Even though Fu Xiong bore the position of foundation minister of the state with power close to that of the sovereign, he was humble in bearing, loved the people, and honored the laws. Thus Fu Jian greatly treasured him, often saying, “Fu Xiong is my Duke of Zhou.”
