夏侯玄
In March 244, Cao Shuang promoted Xiahou Xuan to General Who Subdues the West, and the Inspector of Yong Province, Guo Huai, was appointed as the vanguard commander. Together, they began the march toward Hanzhong via Tangluo Trail. Cao Shuang's protégés, Deng Yang and Li Sheng, participated in the invasion as his staff officers. The primary target of the Wei invasion force was Yangping Pass (陽平關; located west of present-day Wuhou Town (), Mian County, Shaanxi).
