I saw that the train from Tibet to Lhasa is around 9pm. I would like to know how to solve the accommodation problem after arriving?

Get off the car and find a taxi and ask him to take you to the New Century Hotel, Firefighting Hostel, etc., or just ask him to find you a slightly better hotel. You go and ask first. If there is no room, continue looking for the next hotel. There are also many hotels in front of the Industrial and Commercial Bureau of the Autonomous Region, which are relatively cheap. They are on the street outside the Jokhang Temple. If they are not available here, go to Xuexin Village to find them. The hotel conditions here are slightly worse. If they are not available, look for a private guest house. If you are not satisfied, just give the driver 10 yuan more and take you around Lhasa. There are many good hotels in the western suburbs, but they are not cheap.

Be sure to stay in a better place on your first day. It will definitely be uncomfortable to stay on the train for two days. Take a good wash and rest.
