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 became clear that Hulü did not have a positive opinion of him, he bribed Hulü's attendant and asked about Hulü's thoughts on him. The attendant shared that since Mu's rise to power, the Minister Prince had frequently expressed his concerns, stating that a blind leader would inevitably lead to the empire's downfall. Additionally, Mu had previously requested permission to marry Hulü's daughter by a concubine, but Hulü ultimately denied the request.
