《宋书·志·卷十七》
郊祀天地与告祭太庙，其敬重可说是相等，到了郊祀当天尚且可以改移，何况散斋期间呢。 
郊之与庙，其敬可均，至日犹迁，况散斋邪！ 
The worship of heaven and earth in the suburbs and the worship of the imperial temple can be said to be of equal importance. The worship in the suburbs can still be postponed on the day of the worship, let alone during the preliminary fasting period.
