《北史·本记·卷一》
宣皇帝领着国人南迁到大泽，这里有一千多里宽的水面，地上昏黑低湿，便打算继续南迁，可是还未起程便去世了。
宣帝南迁大泽，方千余里，厥土昏冥沮洳，谋更南徙，未行而崩。
Emperor Xuan led the country to move south to Daze, there was a water surface with more than one thousand miles wide, the land was dim and humid, so he planned to continue moving south, but passed away before setting out.
