《宋书·本纪·卷四》
当初北魏军在河北战败后，请求和亲修好；听到高祖驾崩后，又趁机侵扰，河、洛之地骚乱。
初，虏自河北之败，请修和亲；及闻高祖崩，因复侵扰，河、洛之地骚然矣。
In the past, after the Northern Wei army was defeated in Hebei, they had asked to make peace through marriage; hearing of the news of Emperor Gaozu's death, they took the opportunity to harass the region, and the Henan and Luoyang regions were in chaos.
