《资治通鉴·魏纪·魏纪一》
如今曹操虽然已经死去，他的儿子曹丕窃夺了汉朝的皇位。我们应当顺应民心，尽早夺取关中，占据黄河、渭水上游，以利于征讨凶顽叛逆，函谷关以东的义士，一定会自带军粮，驱策战马迎接陛下的正义之师。
今操身虽毙，子丕篡盗，当因众心，早图关中，居河、渭上流以讨凶逆，关东义士必裹粮策马以迎王师。
Now that Cao Cao is dead, his son Cao Pi has taken the throne of the Han Dynasty. We should follow the people's wishes, seize Guanzhong as soon as possible, occupy the upper reaches of the Yellow River and Wei River, so as to attack the fierce and stubborn rebels. The righteous people in the east of Hangu Pass will surely bring their own military rations and drive their horses to welcome His Majesty's army of justice.
