The tour was well arranged. We were informed of the change of train time. The pick ups were on time. The young guide spoke excellent English. My only regret was we could not enjoy the train ride as both the times we got awful seats on the train with no glass window to look outside. I felt claustrophobic the whole time. I ended up straining my neck as I tried to peep through the 10 cm gap behind my back. There went my longing to watch the land of China from a bullet train!..
Almosr every thing was excelente, but there are two things you can improve: the snack and free accesos to Wifi..
