How to take the expressway from Yuncheng, Shanxi to Chongqing?

Take the Lucky Wind Expressway to Fenglingdu, cross the Yellow River and take the Xitong Expressway to Xi'an. When you arrive in Xi'an, take the Ring Expressway directly, transfer to the Beijing-Kunming Expressway all the way to Chengdu (passing Hanzhong on the way), and then turn into the Chongqing Expressway. Go to Chongqing

Or take the 210 National Highway near Hanzhong to Dazhou, and then take the Dayu Expressway to Chongqing. This is a closer way, but that section of the national highway is not easy to walk. It is recommended that you take the previous line
