If you want to ski in yabuli then do a day trip or try or spend as little time there as possible. Make sure your hotel has a restaurant, ours had nothing and we spent a day in our unpleasant room, eating noodles for meals.
.. There is nothing to do on the days you're not skiing. The ski facilities are fine though the skis you can hire aren't the best, as you would expect. There was one tiny cafe near the slope though nothing in English - Yabuli seems to be an ageing resort for Chinese on day trips. Our day skiing with a lesson, clothes, equipment hire, pass & transfers was about £100 each, was a great day but wish we'd left Yabuli that same day
