The reason why northern Shaanxi has always been included in Shaanxi lies in its extremely important geographical location. Before the Tang Dynasty, China's capital was always in Xi'an or Luoyang, and Yulin was close to Ordos, which is the Hetao. The Hetao area has always been one of the most important pastures for northern nomads. In this place, according to the saying in "Emperor Wu of the Han Dynasty", Chang'an can be attacked by surprise in two days! With such a short distance, if Yulin is lost and Yan'an is lost, Chang'an will be opened wide and the country is not far away from being subjugated. But similarly, if you control northern Shaanxi, you can attack Hetao to the west, coordinate Datong and Taiyuan in Shanxi to the east, and coordinate Youbeiping (Fengyuan, Hebei) further away. You can advance, attack, retreat or defend, and you can effectively protect the capital Chang'an. safety. So at this time, northern Shaanxi has always been Shaanxi. Hanzhong is actually closer to the south, and it used to change between Sichuan and Shaanxi. But since the Yuan Dynasty, Hanzhong has been returned to Shaanxi. Hanzhong and southern Shaanxi were returned to Sichuan. It would be difficult to attack Sichuan behind closed doors. The Central Plains regime also had to spend a lot of effort to defend itself against the attacks of the separatist regimes. Zhuge Liang went out of Qishan six times and took advantage of the terrain in Hanzhong. If Hanzhong is placed under Shaanxi's control, it will be difficult for Sichuan's separatist regime to take shape, because the natural dangers of the Qinling Mountains are not in our hands. In other words, the formation of Shaanxi's territory was mainly based on military and political considerations. After Hanzhong was lost, Chongqing was separated again, and Sichuan became a land of trapped dragons. So now some people have been wanting to divide Hanzhong into Sichuan.
