Because of the particularity of Tibet, it is necessary to know some common sense before entering Tibet, but don't worry too much: 1. Psychological preparation: Although Tibet is sacred, it is not a forbidden area. The biggest difference between Tibet and traveling abroad is that Tibet is a plateau, mainly inhabited by Tibetans. First of all, don't be afraid of the plateau. For ordinary people, going to Tibet is nothing more than a trip to the plateau, even if there is a plateau. It is also a normal thing and generally does not lead to life-threatening. Moreover, the medical conditions in Tibet have been greatly improved compared with the past, and it is only a trivial matter to alleviate and treat altitude sickness. So, if you don't have any heart, blood, lung and brain diseases, you can continue. 2. Material preparation: This is also a question frequently asked by Tibetan tourists. It seems that you have to prepare a lot of goods in advance to meet your needs in Tibet. In fact, Tibet is now very developed, and basically everything that can be bought in the mainland can be bought in Tibet. Moreover, due to the improvement of traffic and the development of business, the price is not as expensive as the legend, so if you don't have any special needs, even if you don't bring anything, of course, it doesn't mean that you don't need to bring anything. It just means that when you go to Tibet, you can bring things that other places should like (for example, you should bring sunscreen, lipstick, glasses and other sunscreen products when you go to the plateau). As for medicine, you can buy it in Tibet, especially for the treatment of mountain sickness. It should be said that Tibet is more and better, but according to personal habits, you can bring cold medicine and glasses. If you want to take medicine to prevent mountain sickness, take it a few days before going to Tibet (although it is of little use).
