《三国志·蜀书·邓张宗杨传》
大王现在如果去投靠魏国，魏朝一定会要求您去入朝参见，也要求太子到朝内做人质，如果不从命，他们就有借口征讨叛乱，蜀国也会顺势出兵，这样江南之地就不再是大王能控制的了。 
大王今若委质於魏，魏必上望大王之入朝，下求太子之内侍，若不从命，则奉辞伐叛，蜀必顺流见可而进，如此，江南之地非复大王之有也。 
<number>. Now if you go to Wei, Wei will surely ask you to visit the court, ask your crown prince to be a hostage as well, if you don't obey, they will have an excuse to punish rebellion, Shu will also send troops at this opportunity, and Jiangnan will not be under your control anymore.
