《淮南子·说林训》
西施和毛嫱模样不可能相同，但世上人都称道她们长得好，因为她们容貌美丽是相同的；尧、舜、禹、汤的治国法典是各不相同的，但他们的德政深得人心则是一致的。
西施、毛嫱，状貌不可同，世称其好，美钧也。尧、舜、禹、汤，法籍殊类，得民心一也。
Xishi and Maoqiang couldn't have been more different in appearance, but people all over the world praised them for their beauty, because their beauty was the same; the governance laws of Yao, Shun, Yu, and Tang were different, but their virtues were一致de in the hearts of the people.
