《宋书·志·卷十四》
于是公卿以官贝广泛开展议论侍中高堂膛说：考查自古代建立礼乐制度以来，凡是帝王的兴起，不论是接受禅让还是通过武力登帝王之位，都要改革历法，以此来体现大道，安定民心。
于是公卿以下博议。侍中高堂隆议曰： 按自古有文章以来，帝王之兴，受禅之与干戈，皆改正朔，所以明天道，定民心也。
Then the ministers debated widely the issue, and the Imperial Attendant Gao Tanglang said : By investigating history since the establishment of the rituals and music system, whenever an emperor rises, whether it is by inheriting through abdication, or through a military victory to gain the title of emperor, he must reform the calendar, in this way demonstrating the Great Way to stabilize the hearts of the people.
