In the fifth year of Yuanfeng in the Western Han Dynasty (106), Emperor Wu of the Han Dynasty set up a secretariat department throughout the country. Hanzhong County belongs to Yizhou Secretariat Department. From the first year of Jianwu in the Eastern Han Dynasty to the sixth year (25-30 years), the county government moved to Nanzheng (now Hanzhong City). At the end of the Eastern Han Dynasty, Zhang Lu was divided into Hanzhong and changed to Hanning County; In the 20th year of Jian 'an (2 15), Cao Cao conquered Zhang Lu and changed it to Hanzhong County. In the 24th year of Jian 'an (2 19), Liu Bei still established Hanzhong County according to Hanzhong.

Hanzhong County was founded in the Warring States Period and is located in Nanzheng County (now Hanzhong City, Shaanxi Province). Because it is located in the middle reaches of the Hanshui River, it is named "Hanzhong". During the Western Han Dynasty, its county government moved to Xicheng County (now Ankang City, Shaanxi Province). After the founding of the Eastern Han Dynasty, the county government was moved back to Nanzheng.
During the Three Kingdoms period, the jurisdiction of Hanzhong County was equivalent to the south of Qinling Mountains in Shaanxi Province, the east of Liuba County and Mianxian County, and the west of Glycerol River Basin. Yunxian and Baokang counties in Hubei Province are in the west, and Fenhe and Zhenzhuling are in the north, so it is in the north of Yizhou.
The Han Dynasty implemented a three-level administrative system of state, county and county, and divided the whole country into 13 states. At that time, Hanzhong County was under the jurisdiction of Yizhou (known as Sichuan in ancient times) and was also the gateway to the northern part of Yizhou.
"Three Kingdoms" said: Hanzhong fell, the three public powers were weak, and the Shu people's arms would be cut (three public powers: Yizhou Ba County, Badong County and Brazil County). It can be seen that the importance of Hanzhong county to Yizhou is self-evident
Geographically, Hanzhong County and Guanzhong Basin are separated by Qinling Mountains and Sichuan Basin by Micang Mountain and Daba Mountain, forming an independent small plate. Historically, Sichuan Basin was awarded to Hanzhong, and it can be relied on to solve key problems. Guanzhong basin is in Hanzhong and can sneak into Sichuan.
At that time, Emperor Gaozu Liu Bang enfeoffed Shu, also from Hanzhong County to the north, and finally settled his ministers and ruled the world. At the same time, this is also the reason why Liu Bei and Cao Cao want to compete fiercely for Hanzhong.
