Wei occupied almost the whole of North China. Liaoning in the north and the Yellow Sea in the east. Southeast to the Yangtze River area, southwest to the Qinling Mountains, occupying Xi 'an. Wei was one of the political powers in the Three Kingdoms period, and its territory was in the complete areas of Beijing, Hebei, Liaoning, Shandong and Shanxi provinces, as well as parts of north-central Shaanxi Province, northwest Gansu Province and Jiangsu, Hubei and Zhejiang Provinces.

In Haitou (now west of Lop Nur, Xinjiang), Wei set up the history of the governor of the Western Regions, and also set up Wuji, a captain of the Western Regions, to take charge of Gaochang. In the second year of Huang Chu (22 1), after Sun Quan became a vassal, Cao Wei made Sun Quan own Jingzhou Pastoral, and made Jingyang and other Sun Quan forces Jingzhou, and the northern part of Jingzhou directly under Cao Wei was renamed Yunzhou. After the two sides broke up, Cao Wei changed Yunzhou to Jingzhou.

From the first year of Huang Chu (220) to the seventh year of Huang Chu (226), Longyou was included in Qin Zhou and finally merged into Yongzhou. After the demise of Shu Han, Yizhou was divided into Liangzhou, adding two states.
