《北史·列传·卷三十》
刘芳因为设置的皇帝迎接节气的五处郊社与日月的位置，距离都城的里数，与《礼经》记载不同；另外，对主稼穑的灵星和建立政权，制定了典章制度的周公的祭祀，不应该放在太常寺。便上奏说：
芳以所置五郊及日月之位，去城里数于《礼》有违；又灵星、周公之祀，不应隶太常，乃上疏曰：
Liu Fang memorialised that five altars and shrines dedicated to the seasons and the sun and moon were too far away from the capital, which conflicted with the records in the Book of Rites, and furthermore, the sacrifices made to Lingxing, the deity of agriculture, and the Duke of Zhou, who had established the political order and drafted its legal framework, did not belong in the Grand Temple.
