《陈书·列传·卷二十八》
如强狁骚扰很厉害，作梗我中原地区，开始出自一君，终后却为二主，事有相涉，成言则杂乱难分。
若夫猃狁孔炽，鲠我中原，始自一君，终为二主，事有相涉，言成混漫。
For example, Qiang Xun harassed and obstructed very seriously in the Central Plains area, beginning with one monarch and ending with two monarchs. Since the events were related, the account would be confusing.
