《庄子·外篇·胠箧》
所以说：嘴唇向外翻开牙齿就会外露受寒，鲁侯奉献的酒味道淡薄致使赵国都城邯郸遭到围困，圣人出现了因而大盗也就兴起了。
故曰：唇竭则齿寒，鲁酒薄而邯郸围，圣人生而大盗起。
Therefore, it is said: when the lips are turned outward, the teeth are exposed to the cold; the fact that Duke Lu offered thin wine led to the siege of Handan, the capital of Zhao; when sages appear, great thieves follow.
