Why did so many dynasties choose Xi 'an in Shaanxi as their capital?

Because Xi 'an is safe, both offensive and defensive, and economically located in the inland plain, it has not been called? Land of abundance? You'll know how rich it is here. So why should the ancient capital consider security and economy? From a security point of view, although it entered the Central Plains, it became? Lord of the world? But there are many around? Barbarians? Moreover, when many dynasties built their capitals, the world was still very restless, and it was still possible to change their surnames. The importance of building a capital is no different from that of a person's brain, so we must consider the safety issue.

Otherwise, if it is somewhere in Ma Pingchuan, even if it is the richest place in the world, it can't resist enemies from all directions, then its capital today is useless. Finally became? Build the capital today and destroy it tomorrow? , became a joke, also can't convince the world, so in the early days of a dynasty, must consider the safety of the capital.

So what do you mean by economy, ancient agricultural society and economic prosperity? It means more people! Is the so-called founding of the country for a vast territory? Don't! In fact, the most important thing is that people in this territory rule people, which is the real rule of this territory. Therefore, when deciding the capital, we should also consider whether the block is suitable for accommodating a large number of people and communicating with other places. Otherwise, if the capital is in a ravine, it will take three to five years for the emperor's orders to be conveyed. What's the use of asking the emperor How did the emperor manage the country?

The economy means that there are many people, that is, the geographical location and convenient transportation extend in all directions, which is convenient for the emperor's orders and the government's policies to be conveyed as soon as possible and for the management of the country. Xi 'an, Shaanxi is in such a safe and rich geographical position, so it is natural to be loved by all previous dynasties. Unfortunately, modern society pays more attention to coastal trade, which makes Xi 'an, an excellent geographical environment on land, buried. I'm sorry.
