《汉书·纪·高帝纪下》
现在各侯王封地及名分已定，而和大王同称王号，没有尊卑之别，如此则大王显著的高功盛德，就不能宣明于后世。
地分已定，而位号比拟，亡上下之分，大王功德之著，于后世不宣。
Now the fiefs and ranks of all the marquises and kings have been decided, but they have the same title of king as Your Highness, without distinction between high and low, so the great achievements and virtues of Your Highness cannot be made clear to future generations.
