《吕氏春秋·纪·孟冬纪》
从古到今，没有不灭亡的国家；没有不灭亡的国家，这就没有不被挖掘的坟墓，就人们耳闻目睹来说，齐、楚、燕曾经灭亡过，宋，中山已经灭亡了，赵、魏、韩都灭亡了，它们都成了古国了。
自古及今，未有不亡之国也；无不亡之国者，是无不抇之墓也。以耳目所闻见，齐、荆、燕尝亡矣，宋、中山已亡矣，赵、魏、韩皆亡矣，其皆故国矣。
From ancient times to the present, there is no country that does not perish; if there is no country that does not perish, then there is no grave that has not been excavated. As far as people have heard and seen, Qi, Chu, and Yan have perished, Song and Zhongshan have perished, and Zhao, Wei, and Han have perished. They have all become ancient countries.
