I would like to ask if it is feasible to go this way? Buy a shuttle bus ticket for Delingha in Dunhuang (I will play in Dunhuang for two days before, but you can buy it in advance) to stay in Delingha for one night, and take the bus to the tea card the next day (buy it on the same day Is it difficult to buy?) Go to Chaka for a few hours, then take the shuttle bus to Qinghai Lake 151 to stay overnight (can you buy a ticket like this?) Stay in Qinghai Lake 151 for two days... and then go to Xining (how to buy a ticket? Is it difficult? ?) Or do you have to stop the car? Is it difficult? Thank you!!!
