《汉书·传·张耳陈馀传》
加之张耳、陈馀抱怨陈王不任命他们两个作将军，而让他们作校尉，于是向武臣献计： 陈王不一定立六国的后代为王。
怨陈王不以为将军而以为校尉，乃说武臣曰： 陈王非必立六国后。
Zhang Er and Chen Yu complained that King Chen didn't appoint them as generals, but as military lieutenants, so they offered advice to Wushen: King Chen may not necessarily establish the descendants of the Six Kingdoms as kings.
