《宋书·志·卷十二》
壬迂的《春秋》力图改变这种混乱情况，藉助于赞扬和批评来纠正偏向，管理历法的人安排闰月不当则予以指责并记录下来，登高台颁布朔日就称赞为有礼之举。
仲尼之拨乱于《春秋》，托褒贬纠正，司历失闰，则讥而书之，登台颁朔，则谓之有礼。
Renyu's "Chunqiu" strives to change this chaos, corrects the bias by praising and criticizing, criticizes and records the improper arrangement of the intercalary month by the calendar management personnel, and praises the announcement of the first day of the month on the high platform as a ritual behavior.
