Why didn't you move the capital to Beijing but Xi 'an in the Yuan Dynasty?

1. Economic and historical reasons: historically, as the center of traditional farming civilization, Guanzhong area with Xi 'an as the center is an important granary. However, since the Tang Dynasty, the natural ecology in Guanzhong area has become increasingly bad, with serious soil erosion and hard soil and water. Economic development is declining. With the development and prosperity of new agricultural areas such as Jiangnan and Northeast China, the importance of granaries in Guanzhong is also decreasing. After the Republic of China, in the face of the booming modern commercial civilization and marine civilization, the heavy Xi 'an fell behind.

Historically, Beijing has been the capital for six or seven hundred years since the Yuan Dynasty. The eastward movement of the ruling center has become an irreversible fact. In the historical heritage, it is also a matter of course to choose Beijing as its capital.

2. Geographical and political factors: Guanzhong area with Xi 'an as the center had the roof of North China in Shanxi in the east and the Qinling Mountains in the south to block Bashu in ancient times when all kinds of circulation were not close. It can be completely guarded by the customs, and it is a natural defensive fortress. And to the modern logistics prosperity. All the conveniences of the past have in turn become obstacles. Although Xi 'an is undoubtedly the hub of the northwest region. However, the relatively closed traffic determines that Xi 'an can no longer be an alternative to the capital.

As we all know, during the founding of the People's Republic of China, China pursued a "one-sided" policy, totally leaning towards the Soviet Union. Jiandu and Beijing can connect with the Soviet Union in the shortest distance through Mongolia. Xi' an, which is located in the mainland, does not have this condition.
