《容斋随笔·卷十·战国自取亡》
其他四个国家，魏国在魏惠王时衰亡，齐国在齐闵王时衰亡，楚国在楚怀王时衰亡，赵国在赵孝成王时衰亡，根本原因都是好用战争侵占土地的缘故。
彼四国者，魏以惠王而衰，齐以闵王而衰，楚以怀王而衰，赵以孝成王而衰，皆本于好兵贪地之故。
The other four countries, Wei declined during the reign of King Hui of Wei, Qi declined during the reign of King Min of Qi, Chu declined during the reign of King Huai of Chu, and Zhao declined during the reign of King Xiaocheng of Zhao. The fundamental reason is that they all use war to invade land.
