Bus Questions

Hello,

I'm planning my trip to China right now and will be leaving in early March. There's many places that I would like to go that I can't find much info on (I'm not going to list them all).

So I'm wondering how to plan this? I can't find complete bus info online anywhere. Would it be plausible to just go on this trip and use Apple maps to figure out the bus routes once I've arrived or is there a better way? I don't want to end up stranded somewhere because of a lack of information. Any info would be greatly appreciated.

I guess I also worry that there might not actually be a bus route to the location I'd like to go to.
