《南齐书·志·卷九》
作为太子在束宫时，也随从参加郊祭，如果说以前的虔诚可以代替后来的恭敬，新朝代创始，就无须再有配祀上天的祭礼了。
储后在宫，亦从郊祀，若谓前虔可兼后敬，开元之始，则无假复有配天之祭矣。
As a prince in the Chu Palace, he also participated in the suburban sacrifices. If the previous piety can replace the later respect, then when a new dynasty is founded, there is no need for sacrifices to the heavens.
