First the duration: i've read about a 30 minute express bus, a 1 and 1/2 hours bus, 3h drive and even 6.5h by touristbus.
Then the hours when they run. I've read they only run until noon, is that true?
We'll be arriving by train from Datong either at 5am or at 2.18pm. Arriving at 5 leaves us time to figure things out but arriving at 2 would mean being stuck in zhengzhou...
i hope someone can shed some light on this.
