Where is the geographical advantage of "Xi 'an" lasting for thousands of years?

Xi 'an has superior natural conditions and convenient transportation, and has been a battleground for military strategists since ancient times. I am studying in Xi 'an now, and I can really feel these three points. I feel this is a great tourist city when I go out every day. Xi 'an has developed very well in recent years, with the title of "the ancient capital of the Six Dynasties" as the foundation, and some network celebrities have developed their punching cards, and countless people come here every day. I only have one feeling when I go to Datang city that never sleeps every day, that is, there are many people.

0 1, the natural conditions are unique.

Xi 'an is located in Guanzhong Plain, close to the Yellow River, and its position as a "granary in the world" has never wavered since ancient times. Xi is located inland, not in the earthquake zone, so it is rarely disturbed by natural disasters. Xi 'an is located in the northwest, with four distinct seasons and large temperature difference between day and night, which is beneficial to the growth of crops. Moreover, Xi 'an has many rivers, abundant rainfall and convenient irrigation. In ancient times, people depended on the weather for food, so we can't let it be here. ?

02, convenient transportation extending in all directions.

Again, there are many rivers in Xi 'an, and the "Eight Rivers in Chang 'an" is not a hollow name, so the water transportation here in ancient times is very developed. In ancient times, there was only land and water transportation, and many times you could not choose. This may be the only way to travel or transport. In addition to water transportation, Xi 'an has three customs, namely Hangu Customs, Pujin Customs and Wuguan Customs, which can lead to all parts of the country. This is also a major factor in the capital of kings.

03, the military fortress is easy to defend but difficult to attack.

The biggest reason is that Xi 'an is a place that is easy to defend but difficult to attack. Besides rivers, there are endless mountains in Xi. To the south of Xi 'an is the Qinling Mountains. If you want to make a phone call, it's not an easy task. Coupled with the continuous improvement and perfection of fortifications in various dynasties, Xi 'an has become a military fortress. Occupy Xi 'an, as long as you don't commit suicide, basically the rule is very stable. There is also a feng shui saying, which probably means that it is surrounded by mountains and waters and suitable for the real dragon emperor to live in.
