Is it better to drive from Beijing to Chengdu on Taiyuan Line or Zhengzhou Line?
How many days does it take to take Zhengzhou Line? See how far you can run in one day.
From Beijing, take Beijing-Zhuhai Expressway to Zhengzhou, then take Sanmenxia in Luoyang to Xi 'an, pass Hanzhong and enter Sichuan. The road conditions are basically expressway. I hope the answer will help you.
