Zu, realizing that Hulü disliked him, bribed Hulü's servant and asked the servant about Hulü's opinion of him. The servant stated, "Ever since you came into power, the Minister Prince each night sighed and stated, "With a blind man in power, the empire will surely be destroyed." Meanwhile, Mu had once requested to marry Hulü's daughter by a concubine, but Hulü refused.
As it turned out, Hulü did not favor him, so he bribed Hulü's attendant and asked about Hulü's opinion of him. The attendant revealed that since Mu's rise to power, the Minister Prince had expressed his worries every night, saying that a blind leader would surely destroy the empire. Moreover, Mu had once requested permission to marry Hulü's daughter by a concubine, but Hulü refused.
