《宋书·志·卷十五》
像这样那么洪水之灾便救治不了，因此让死在陵的便葬在山陵，死在湖泽中的便葬在湖泽 小安葬时用桐木做成的棺材衹有三厚，守丧时间为三天。
故使死于陵者葬于陵，死于泽者葬于泽。桐棺三寸，制丧三日。
In this way, such a flood disaster cannot be saved. Therefore, those who died in the mausoleum should be buried in the mausoleum, and those who died in the lake should be buried in the lake. The coffin made of paulownia wood used in the funeral is only three thick, and the mourning period is three days.
