《礼记·乐记》
桑间蹼上之音，属于亡国之音，它反映了国家政治的极端混乱，老百姓的流离失所，统治者的欺上瞒下自私自利而不可救药。
桑间濮上之音，亡国之音也，其政散，其民流，诬上行私而不可止也。
The music of Sangjian and Powei belongs to the music of a doomed and亡国之音 annihilated country, reflecting the extreme chaos and turmoil of the national politics, the displacement and homelessness of the people, and the incurable deceit, selfishness, and corruption of the rulers.
