曹真
During this meeting with Cao Rui, Cao Zhen proposed launching a large-scale invasion of Shu from multiple directions to eliminate the threat once and for all. Cao Rui approved his proposal and personally saw him off from Luoyang. In September 230, Cao Zhen led an army from Chang'an to attack Shu via the Ziwu Valley (子午谷). At the same time, another Wei army led by Sima Yi, acting on Cao Rui's order, advanced towards Shu from Jing Province by sailing along the Han River. The rendezvous point for Cao Zhen and Sima Yi's armies was at Nanzheng County (南鄭縣; in present-day Hanzhong, Shaanxi). Other Wei armies also prepared to attack Shu from the Xie Valley (斜谷) or Wuwei Commandery. However, the campaign eventually had to be aborted in October 230 because the gallery roads leading into Shu were too damaged for the troops to pass through, and also because of rainy weather lasting more than 30 days.
