《梁书·列传·卷四十八》
假若为慈母服丧衹是在卿大夫范围之内，查核诸侯之子还没有按这规定服丧，更何况是皇帝之子呢。
傥其服者止卿大夫，寻诸侯之子尚无此服，况乃施之皇子。
If mourning loving mothers is only within the scope of the 卿大夫 (qing大夫), then it is clear that the son of a marquis has not mourned according to these provisions, and it is even less likely that the son of an emperor would do so.
