Budget Accomodation at Mutianyu Great Wall

1. Would you mind telling me the meaning of "ming shu"? Anyway, you can easily check in a farmer house or hostel in the village. No need to book in advance.
2. I can just say there is possibility that it will snow in mid Dec. As for the exact weather condition, u'd better pay close attention to the weather forecast for due time.
3. As I know, the last bus of no. 916 leaves Huairou around 19:00.
