《资治通鉴·唐纪·唐纪八》
御史大夫杜淹说： 北齐将要灭亡时，产生《伴侣曲》；陈国将亡时，又出现《玉树后庭花》，其声调悲哀，过路人听到了都悲伤落泪，怎么能说政治的兴衰隆替不在于音乐呢？ 
御史大夫杜淹曰： 齐之将亡，作《伴侣曲》，陈之将亡，作《玉树后庭花》，其声哀思，行路闻之皆悲泣，何得言治之隆替不在乐也！ 
President of the Censorate, Du Yan said: When the Northern Qi was about to perish, the "Companion Ballad" came into being; when the Chen state was about to perish, the "Jade Tree Rear Court Flower" was composed, its tune was sad, and passers-by who heard it all burst into tears, how could you say that rise and fall of the politics are not based on music?
