《三国志·吴书·吴主五子传》
自光武帝中兴以来，对众王有所约束，只能在宫中自我娱乐，不得治理百姓，参与政事，与他们来往的，都有严格的限制，于所以他们各人都得以保全安定，保住福运。
自光武以来，诸王有制，惟得自娱於宫内，不得临民，干与政事，其与交通，皆有重禁，遂以全安，各保福祚。
Ever since the restoration of Guangwu Emperor, the kings were restrained. They could only have some entertainment in the palace, they could neither discipline the people, nor participate in the government affairs, and people who communicated with them were strictly limited, so they could all be safe and stable, and keep the favor.
