What kind of hat do you need to wear when traveling in Tibet?

Big hats are the best. Just prepare some cold medicines, gastrointestinal medicines and some medicines for clearing heat and relieving pain for routine travel, such as Ganmao tablets, Ganmao granules, Xieliting, compound aspirin, chlorpheniramine and antibiotics. If you have no confidence in altitude sickness, you can prepare some anti-altitude sickness drugs: Rhodiola (taken at least 10 days in advance), Baifuning (to control the headache caused by altitude sickness) and Gao Yuan 'an. Standing drugs: Niuhuang Jiedu Tablet, Berberine, Perio, Cismin, Chengyunning; Anti-altitude sickness drugs: Nuodikang capsule, American ginseng (very useful for relieving extreme fatigue), quick-acting jiuxin pills; External use: Yunnan Baiyao, Wanhua oil, band-aid, cooling oil, essential balm, Shangshi Zhitong ointment, eye drops, cotton wool, gauze, bandage and white adhesive tape; Vitamins: Jinshi Erkang, Shanshu tablets and other vitamin tablets. Of course, it is also important to keep healthy in Tibet. There is a great temperature difference between day and night in Tibetan areas. Add or delete clothes at any time. Don't catch a cold.
