《汉书·传·张陈王周传》
过了十多个月，有人劝周勃说： 您已杀了吕姓诸人，立了代王，威震天下，而您接受厚赏处在高位并以此为满足，便会大祸临头了。 
居十余月，人或说勃曰： 君既诛诸吕，立代王，威震天下，而君受厚赏、处尊位以厌之，则祸及身矣！ 
After more than ten months, someone told Zhou Bo that: You'd already killed the people of the Lu family and made the King of Dai the emperor. Your prestige shakes the country and yet you're so contented with accepting heavy rewards and staying in such a high position. You'll get into big trouble.
