Mei County
In the spring of 228, Zhuge Liang ordered Zhao Yun and Deng Zhi to lead a detachment of troops to Ji Valley () and pretend to attack Mei County (郿縣; southeast of present-day Fufeng County, Shaanxi) via Xie Valley (). Their mission was to distract and hold the Wei general Cao Zhen's attention, while Zhuge Liang led the Shu main army to attack Mount Qi (祁山; the mountainous regions around present-day Li County, Gansu).
