《资治通鉴·晋纪·晋纪三》
汉代的诸侯王，地位在丞相、三公之上，但如果进入朝廷佐助朝政，就要有兼职，如果离开朝廷去封国，也不再给予高级职务的虚名作为尊贵的恩宠。
汉诸王侯，位在丞相、三公上，其入赞朝政者，乃有兼宫，其出之国，亦不复假台司虚名为隆宠也。
The vassal kings of the Han Dynasty were higher in status than the prime minister and the three dukes, but if they entered the court to assist the government, they would be concurrently. If they left the court for the vassal state, they would no longer be given the top jobs as their courtesy titles.
