《史记·三十世家·曹相国世家》
百姓们歌颂曹参的事迹说： 萧何制定法令，明确划一；曹参接替萧何为相，遵守萧何制定的法度而不改变。
百姓歌之曰： 萧何为法，顜若画一。曹参代之，守而勿失。
The people sang songs praising Cao Can's good deeds: "Xiao He implemented the laws, clarifying and unifying them; Cao Can took over as prime minister from Xiao He, and he protected Xiao He's regulations without changing them."
