How to get from Pingdingshan to Dunhuang?

I am from Dunhuang. Pingdingshan can't go directly to Dunhuang, so I have to change trains at Xi 'an. Best advice for you: Take K625/K628 in Pingdingshan at 23: 17 and drive to Xi 'an at 06: 59. 7 hours and 42 minutes on the road, hard seat ticket 76. Then you can take a break and go to the Internet cafe, then take the K59 1 from Xi 'an to Dunhuang, and the departure time is 10:56. It takes 22 hours and 34 minutes to get to Dunhuang Road at 9: 30 the next morning, and the hard seat ticket is 208. So Pingdingshan -Xi 'an. The waiting time in Xi is 4 hours.
