There are some questions about traveling to Tibet, thank you in advance ~

The best time is from May to September. Be sure to bring your camera, sunscreen, sunglasses, sun hat and duck down vest. Going to Lhasa by train, the scenery along the way is beautiful. You can change planes in Chongqing or Chengdu when you come back. Holiday Inn Jin Zang Ka Lin on Zhu Jin West Road costs 180 yuan every day, which is close to the railway station and the city center. You can contact the hotel's travel agency or charter an off-road vehicle, and the price is about 3-4 yuan per kilometer. Namtso, Yang Zhuo Yongcuo, Karola Glacier, Nyingchi and Nangarbawa Peak must be visited. Just go to Potala and Jokhang Temple in the city. Take Nuodikang capsules (Rhodiola oral liquid and Gaoyuan 'an are better) and American ginseng buccal tablets three to five days before going, and then continue to eat when you arrive. Also, don't do strenuous exercise, walk slowly, don't take a shower, don't drink and smoke, don't overeat and don't catch a cold. Everyone has altitude sickness, some light and some heavy, but they won't come right away. Don't be careless
