《世说新语·言语》
这时，侍中裴楷进言道： 臣听说，天得到一就清明，地得到一就安宁，侯王得到一就能做天下的中心。 
侍中裴楷进曰： 臣闻天得一以清，地得一以宁，侯王得一以为天下贞。 
At this time, Shizhong Pei Kai said: I heard that if the heavens get one, they will be clear and peaceful, if the earth gets one, they will be peaceful, and if the princes get one, they can become the center of the world.
