《三国志·魏书·程郭董刘蒋刘传》
即使您处在偏远的地方，依附仁德高义的主君，安居在像泰山那样稳固的地方，但就算身为王子乔和赤松子两位仙人那样的人，从道义的角度来讲，依然应该抛弃那边而转向我们这边，舍弃百姓而保全父亲。
曹公愍其守志清恪，离群寡俦，故特遣使江东，或迎或送，今将至矣。就令足下处偏平之地，依德义之主，居有泰山之固，身为乔松之偶，以义言之，犹宜背彼向此，舍民趣父也。
Even if you live in a remote place, depend on a benevolent and righteous lord, and reside somewhere as stable as Mount Tai, even people as immortal as Prince Qiao and Chisongzi, from a moral standpoint, should still abandon that side and turn to this one, abandon the people, and save your father.
