Who can help me make a detailed plan, including what bus to take from Xi' an and where to get off, the ticket price and so on?

If you go, prepare thicker clothes (Guanshan Ranch also has rented coats, 20 yuan each);

By bus: there is a direct bus from Chengxi Bus Terminal to Longxian County. 55/ Nobody

Depart from Longxian County, and then take a bus directly to Guanshan Ranch 16/ person.

Play: If you want to spend the night in Guanshan Ranch, you should first look for yurts (50 rooms). Then, of course, riding a horse! 35/ per person per hour. After that, I will go skiing! There is nothing to play. In the evening, I will attend a bonfire party and eat roast sheep! You can go back the next day.
