《资治通鉴·唐纪·唐纪八》
太宗说： 朕从前曾受命专行率兵征伐，民间于是流传着这个曲子。虽然不具备文德之乐的温文而雅，但功业却由此而成就，所以始终不敢忘本。 
上曰： 朕昔受委专征，民间遂有此曲，虽非文德之雍容，然功业由兹而成，不敢忘本。 
Taizong said, "I once received an order to personally command an army on a campaign. This music was therefore spread among the people. Although it does not have the gentle and elegant qualities of music of moral virtue, it is because of this that accomplishments were achieved. Therefore, I never dare to forget my roots. "
