Xi 'an has a relatively high political status and strong strength in finance, transportation and foreign exchanges. Xi is the most important central city in northwest China, as well as a national central city and a sub-provincial capital city.

Therefore, Xi is better than Changsha in finance, transportation and foreign exchange. Some people may say that the traffic in Changsha is also very convenient. On the Beijing-Guangzhou axis of the north-south traffic artery, there is also a Shanghai-Kunming high-speed railway in the east-west direction, and the water, land and air traffic is very good. Xi is the transportation center of the country.
