Out of the land of feng shui.

At that time, the western regions were rich in mineral resources, with vast forests and grasslands, which were suitable for human habitation and military training, so they wanted to capture the western regions.

The ancient western regions were rich in resources and vast in land. Whoever can dominate this bustling place will have the source of war. It will be able to have a strong supply capacity, which is very important in the age of weapons. During the reign of Emperor Xuandi of the Han Dynasty, the western regions had established the Duhu government, and the western regions were incorporated into Chinese territory for the first time. In addition, at that time, the small countries in the western regions were independent and their contradictions were parallel, which was also the main reason why the Central Plains Dynasty wanted to capture the western regions.

With the change of dynasties and the further decline of Han Dynasty in China, the role of the western regions as government protectors became smaller and smaller, and the western regions entered a long-term scuffle. It was not until the reunification of the Eastern Han Dynasty that Ban Chao regained control of the Western Regions. Unfortunately, the Eastern Han Dynasty was too short, and it didn't take long to lose its territory. At that time, the Central Plains also began the chaotic period of the Northern and Southern Dynasties. During this period, the regime was not long, and no king could effectively control the western regions. It was not until the Sui and Tang Dynasties that the powerful central government conquered them.

After the end of the Sui and Tang Dynasties, hundreds of years passed, and in the Yuan Dynasty, Mongolians migrated rapidly at that time, and Mongolia could have an area of tens of millions of square meters. Later, the Yuan Dynasty split from it, with a territory of nearly 10 million square kilometers, including the Western Regions. In the Qing Dynasty, there was another territorial expansion, from Kangxi until Emperor Qianlong pacified Junggar and once again took control of the Western Regions. At that time, great changes have taken place in all countries in the world, and it is even more necessary to recover the treasure land of the western regions.

For the ancient Central Plains dynasty, whoever controlled the western regions could get through the rapid development of the Silk Road, speed up the economy and strengthen the country, which shows the importance of the western regions.
