How to get from Xi to Changsha by self-driving expressway?

The whole high-speed way is: Xi' an to Zhengzhou, Wuhan and Changsha. I suggest you bring a navigator, which is very convenient. As long as you enter the destination, you don't have to worry about going the wrong way. When you arrive in Changsha, you can also take you to find hotels and visit scenic spots, which is particularly convenient and you will never go wrong. It can give you a variety of route choices. It is about 1000 km from Xi 'an to Changsha. If it's 1000 km and Audi 2.0T turns on the air conditioner at high speed, it will consume 120 liters of gasoline! The unilateral toll will not exceed that of 500 yuan.
