What attracted the rulers of past dynasties to regard Xi 'an as the core of a country?

First, the military terrain is suitable for offensive and defensive purposes.

Second, a superior economic base.

Three. Convenient traffic conditions and others

China has always been a big agricultural country in history. First of all, "eight hundred miles of Qinchuan drought and flood protection" was the first choice of the central government at that time. To be stable near the capital (like the low score in the college entrance examination in Beijing now), food is the first thing for the people, and Chang 'an has a material foundation.

The geographical "eight rivers around Chang 'an" is very important in ancient water conservancy, and Chang 'an also has advantages in water conservancy.

There are Qinling Mountains in the south-central part of Guanzhong, Longshan Mountain in the west, Loess Plateau in the north, Yellow River graben in the north and northwest, which can be used as a shield, and Yellow River in the east. There are natural terrain barriers on all sides, which are easy to defend but difficult to attack.

As the national capital, it should be easy to control the world. The origin of China is Xi 'an (Xi 'an belongs to the northwest, but its geographical location is the center of China).

And the ancient people's understanding of feng shui. Coupled with the architecture of the last dynasty and hundreds of years of cultural precipitation, it is more likely to become the capital of the next dynasty.

Which school is it? It is exactly the same as the question I answered last time.
