《宋书·志·卷十九》
所以在祭天祭祖中进献，鬼神因它的和谐而享用，在朝廷演奏，君臣因它符合礼度而高兴。
故荐之郊庙，而鬼神享其和；用之朝廷，则君臣乐其度。
Therefore, when it is offered in sacrifices to heaven and ancestors, ghosts and gods enjoy it because of its harmony, and when it is played in the court, the monarch and his subjects are happy because it conforms to propriety.
