What should I prepare for my trip to Tibet at the end of August?

I have just been to Tibet, where prices are actually higher. You should have enough money, but don't buy it indiscriminately. Take an umbrella, a portable one, a hat and a pair of sunglasses to keep out the sun and rain. You can also buy a shawl to wrap your face in Tibet. Very cheap and beautiful. Remember to bring a cotton-padded jacket and short sleeves, plus a long-sleeved thin cardigan and a pair of pants. You don't have to change it over there. Just like going to Namco and Yanghu during the day, it can freeze people to death. And olive oil. It's quite dry there. Cotton swab, this is used to rub some olive oil in your nose. Otherwise, you will feel that sleeping at night is like cutting your nose with a knife, and there will be blood clots in your nose the next day. Bring your own snacks and something light. If you like apples, bring your own. Apples and watermelons there are quite expensive. It is very important to replenish water or repair the mask after sun exposure. It's really dry there Moisturizing lotion and sunscreen SPF25 are enough, because almost all the group members are in the car, remember to bring wet tissues, because sunscreen should be applied frequently, so that you can wipe it. And it's best to bring your own towel, that kind of disposable towel, which dries quickly. That's enough. Bring more for those who love to bring. There is nothing there but dryness. As for drying, don't worry. An umbrella with a hat or a shawl is enough. I'm not black at all. By the way, there are two or three places where you and your group go to sell things almost every day. You can't trust those who sell health care products and medicines. Forget the yak horn comb. Yak meat tastes similar to beef, but it's expensive. What pendant? Relax. Anyone who wants to resist altitude sickness can sell it there, which is very useful. By the way, remember to bring the kettle. It's OK in downtown Lhasa, but in the scenic spot, water is very expensive. You can go out and fill the hotel with boiling water in the morning. At noon, there is water or tea in the restaurant. Remember to take it with you. Also, never go to Tibet by train. Some people have altitude sickness and vomit in the toilet. It's painful. It's tiring to take the train.
