Thank you Mr Wang,

But I also found this info:
There are three long-distance buses that run to nearby cities such as Beijing,Tianjin, Shijiazhuang, and Zhangjiakou daily from Chengde.
Mini buses run every 30 minutes from 06:00 until 16:00 between Chengde Long-distance Bus Station andBeijing Xizhimen Long-distance Station daily.

--> So there are busses going to Chengde from Beijing, from two stations, Xizhimen and Dongzhimen?
--> If yes, which is the nearest busstation to Simatai?
--> Does the longdistance bus have a busnumber?

Thank you,
Regards
