Guanzhong is close to Qinling Mountains, and Weihe River passes through it, with rich products and outstanding people. There are natural terrain barriers on all sides, which are easy to defend but difficult to attack. Since the Warring States period, there has been a saying of "one country, four blockades". Therefore, in the Han Dynasty, Zhang Liang summed up the advantages of Guanzhong with "a golden city of thousands of miles" and persuaded Liu Bang to make it the capital of Guanzhong.
2. Hanzhong, namely Hanzhong City, is located in the geographical and geometric center of Chinese territory, in the southwest of Shaanxi Province. It belongs to the northwest in administrative division, and the geographical and natural environment belongs to the southwest. Hanzhong City borders Qinling Mountains in the north, Baoji City and Xi City in Shaanxi Province, Daba Mountain in the south, Guangyuan City and Bazhong City in Sichuan Province, Ankang City in Shaanxi Province in the east and Longnan City in Gansu Province in the west.
3. The Central Plains, also known as Middle Earth, Zhongzhou and Huaxia, refers to the middle and lower reaches of the Yellow River with Luoyang to Kaifeng as the center. In a narrow sense, it refers to today's Henan Province. Corresponding to foreign countries, the Central Plains also refers to China.
The Central Plains, which originally meant "Yuan Ye under heaven", is the birthplace of Chinese civilization and Chinese civilization, the cradle of the Chinese nation and regarded as the center of the world. With the great integration of the Chinese nation and the expansion of the Central Plains civilization, the Central Plains region gradually spread outward, expanding the communication between the Han nationality and all ethnic groups with the Central Plains culture as the core. The reason why the Chinese nation with relatively advanced culture is called China is because it is different from overflowing.

Hexi is a battleground for military strategists.
Hexi region refers to Jiuquan, Zhangye, Wuwei and other places in Gansu today. Because it is located to the west of the Yellow River, it has been called Hexi since ancient times. Its dip angle is between Qilian Mountain and the northern mountain range, starting from Wushaoling in the southeast and ending at the lower reaches of Shule River in the northwest. It is only a few miles wide to one or two hundred miles, and it is more than 2,000 miles long. It has become a long and narrow natural corridor, also known as Hexi Corridor, which is the throat of the Central Plains leading to the western regions.
Hexi is located in the northwest arid area, and there are large alluvial plains in Shiyang River, Weak Water and Shule River basins, with fertile soil and beautiful aquatic plants, which are suitable for agriculture and animal husbandry. Qilian Mountain is covered with snow all year round and melts in spring and summer, which is especially suitable for developing "oasis agriculture". Historically, this is an agricultural area famous for its wealth. Pre-Qin history refers to the area west of Yuncheng section of the Yellow River and east of Shuijing, which is the throat of Guanzhong Plain and Hedong area.
During the Spring and Autumn Period and the Warring States Period, Hexi area refers to the area west of Yuncheng section of the Yellow River and east of Shuijing. Jin and Qin in the Spring and Autumn Period and Wei and Qin in the Warring States Period fought for this area for more than 300 years and hundreds of battles. After the war ended in 345 BC, Qin Huiwen lived in Hexi area of Wang Zhanling.
During the Western Han Dynasty, Hexi area was originally the territory of Dayue people. Later, Mao Dun Khan defeated Da Yueshi, forcing him to move westward and be occupied by Xiongnu.
After Emperor Wudi defeated the Xiongnu in the Battle of Hexi, the Western Han Dynasty completely occupied the Hexi Corridor and opened the road to the Western Regions.
