How much does it cost to travel from Huzhou, Zhejiang Province to Tibet without a group tour?

It is better to change trains from Xining to buy tickets. For a meal, it's more than ten yuan. The youth hostel has a bed of 50. I don't know if it's easy to find it in the peak season, but there are quite a few places to live. The main expensive place is chartered car. It should be easy to carpool with everyone. Save 4 thousand in ten days, which is almost enough. We may have spent less than 4,000 in eight days in Tibet last time, but we still need to take more just in case. Remember to wear a windbreaker when you get dressed. If it is too high, it will only be a tragedy. I heard that eating rhodiola in advance will have a preventive effect. I wonder if it will be useful?
