Xi, the capital of Shaanxi Province, is located in Guanzhong Plain, with warm climate, fertile soil, dense river network and abundant water resources, which is very suitable for human habitation. In addition, Xi is surrounded by the Yellow River and the Qinling Mountains, which leads to the northwest traffic area. It is a military fortress that can be attacked and defended on three sides, and many emperors like to build their capital here.

Xi is a famous historical and cultural city. Xi is also one of the important birthplaces of Chinese civilization and the Chinese nation and the starting point of the Silk Road. More than ten dynasties established their capitals here in history. There are countless capitals, such as Epang Palace in the Qin Dynasty, Terracotta Warriors, Weiyang Palace in the Han Dynasty, Changle Palace, Daxing City in the Sui Dynasty, Daming Palace in the Tang Dynasty, Xingqing Palace and so on.

Historically, the capitals of thirteen dynasties were all in Xi 'an. This situation also makes Xi 'an have more ancient tombs than other cities, and even the subway will dig up ancient tombs.

Xi 'an subway construction is slow, which has been heard all over the country, but everyone can understand. After all, it used to be the ancient capital of the 13th Dynasty, with many underground cultural relics. Subway construction is often stopped so that professional cultural relics protection personnel can carry out archaeological excavations before continuing construction. For example, during the construction of Xi Metro Line 2, more than 100 underground tombs were discovered and more than 200 cultural relics were unearthed. In addition, the subway line has to pass through ancient ruins such as city walls and bell towers, and the construction difficulty can be imagined, so everyone can understand the slow construction progress.

On average, as many as 300 ancient tombs are excavated every year, and ancient tombs are unearthed almost every day. As an important education center, Xi 'an also has many universities. These universities located in Xi 'an and excavating ancient tombs are called ancient tomb universities by the world.

Why are there so many capitals in Xi 'an? In fact, this is related to the prosperity of the city. It was very difficult to build a city in ancient times. On the one hand, there is not enough manpower, on the other hand, there are not so many resources, so most dynasties choose the capital city as the most prosperous city in the previous dynasty.

So many dynasties established their capital in Xi 'an, not because of Long Mai, but because Xi 'an was built so well after the capital was established in the first dynasty. Future generations will never look for a new capital again. After all, everyone is willing to enjoy success and save manpower and financial resources.
