In the afternoon, there are only buses from Xi 'an to Pingliang or Jingning in Gansu. Jingning passes by Longde, and Pingliang is about an hour's drive from Longde.
After the Liupan Mountain Tunnel, there is Yangjiadian Folk Culture Village, with accommodation and accommodation in the county. Last time I took two friends to the Golden Elephant Hotel diagonally opposite the bus station, it was ok, the standard room was 100, but there was no air conditioning (it seems that all the small hotels in Lund didn't have air conditioning).
