Hello everyone

Im not sure if I got the question in the right section of the forum, if not please forgive me.

Im currently planning a trip to Yunnan region in China. Since I never been in China at all , im not sure what to expect.
Could someone please give me some tips how to navigate in Chinese traffic? Do they have any traffic signs which can be read in other language than Chinese characters? Or is it best to use GPS device ?

Any advice is well appreciated!
Thanks !
