Never be late (which is impossible if you come from Vietnam by Pingxiang : the only one available train starts every day from Pingxiang at 14h30 and is so slow that you can't be in Nanning before 8h30 o'clock... :-( ) and get first a working wechat ! as it becomes impossible for us to get wechat working normally :-( , this means this YH is not available for foreigners...
