《水经注·卷十七》
《魏氏春秋》说：诸葛亮占据了渭水的南原。司马鼓对诸将说：诸葛亮若从武功出兵，依山势转向东边，那就是他的胆略了；如果他西上五丈原，诸位就都平安无事了。
《魏氏春秋》曰：诸葛亮据渭水南原，司马懿谓诸将曰：亮若出武功，依山东转者，是其勇也。若西上五丈原，诸君无事矣。
Wei Shi Chunqiu stated: Zhuge Liang occupied the Southern Plain of Wei River. Si Ma said to the generals: if Zhuge Liang attacks from Wugong, turns to the east according to the terrain, then that is his courage; if he goes west and goes up to Wuzhangyuan, then you will all be safe and sound.
