《晋书·帝纪·第一章》
宣帝跟随曹操去讨伐张鲁，对魏武帝进言道： 刘备以欺诈和武力俘虏了刘璋，蜀人尚未归附就出兵远方去争夺江陵，这个机会不能错过。
从讨张鲁，言于魏武曰： 刘备以诈力虏刘璋，蜀人未附而远争江陵，此机不可失也。
Xuandi followed Cao Cao to conquer Zhang Lu and advised Cao Pi: Liu Bei captured Liu Zhang through deception and force. The people of Shu had not yet surrendered and he sent troops far away to compete for Jiangling. We cannot miss this opportunity.
