Help urgently! ! ! Award 50 points! How to take the expressway from Datong to Xibaipo, what is the route, online and so on! ! !

Although I haven't walked, I can teach you a way. When you get to expressway, ask the toll collector of expressway toll station where you get off the expressway and how many kilometers, so that you can watch the odometer go. When you get off the expressway, ask the toll collector at the toll booth which direction to take, which way to take and how far it is.

Anyway, when I drive out and don't know the way, I always take this road. Look at the road signs and ask around. You can't go wrong.
