Finally ! After 5 hours at the Chinese border to change again the carriage boggies as we did back in Belarus (which seemed ages before !) and after a last night in the train, finally we arrive in China for a first stop in Datong.
There, they changed the chinese orange coal locomotive we had had at the border for a blue electricity powered one. At least we felt we saved some more trees running on electricity rather than coal.
Oh wait… where does most electricity come from in China ? Damn it.
