《陈书·本纪·卷一》
周文王、周武王遣两位帝王英明圣武，在天道上还继续沿袭，六夷贪婪狡诈，争相入侵中原，郡县之令称王，各自设立都城，自立为帝，人们怀有违法犯纪的心思，即使一个小民，一尺土地，也并非是凿塑所有。
二后英圣，相仍在天，六夷贪狡，争侵中国，县王都帝，人怀干纪，一民尺土，皆非梁地。
King Wen of Zhou and King Wu of Zhou sent two emperors to be wise and martial, and they continued to follow the way of heaven. The six barbarians were greedy and treacherous, and they competed to invade the Central Plains. The county magistrates called themselves kings, each established a capital, and established themselves as emperors. People had the intention of violating the law, even a small people, a foot of land, is not all owned by Zao Su.
