《列子·杨朱》
夏粱凭借历代祖先的资本，占据着天子的尊贵地位，智慧足以抗拒众臣，威势足以震动海内；放纵耳国所想要的娱乐，做尽意念想做的事情，高高兴兴地一直到死。这是天子中安逸放荡的人。
桀藉累世之资，居南面之尊，智足以距群下，威足以震海内；恣耳目之所娱，穷意虑之所为，熙熙然以至于死：此天民之逸荡者也。
Xia Jie relied on the capital of his ancestors, occupied the noble status of the Son of Heaven, and was wise enough to resist his ministers, he was prestigious enough to shock the whole world; he indulged in the pleasures that his ears wanted to listen to, he did everything his mind wanted to do, he was very happy until he died. This is the comfortable and dissolute person among emperors and kings.
