What should I bring with me when I go to Yunnan in June and July for about 15 days?

Yunnan has a large temperature difference between day and night. In the mountainous areas of Yunnan you can see people wearing clothes for all seasons at the same time. There is a saying that "a rain makes winter". As long as it rains, the temperature will definitely drop. July has entered the rainy season, so you still need to prepare some warm clothes. For girls, a 50L backpack is enough. The main reason is to consider physical strength and make it as streamlined as possible. The necessary items include a sleeping bag (limit temperature -10), moisture-proof pad, raincoat (for outdoor use that can cover a backpack), a few pairs of thick socks (shock-absorbing foot protection), hiking shoes (waterproof, V-soled, don’t buy cheap ones) and fakes, otherwise the beautiful journey will turn into purgatory), strong light flashlight or headlamp (there are smaller rechargeable ones), sunscreen (SPF30 or above), hat (large brim sun protection), do not use sunglasses Too deep (too deep will cause you to misjudge the light, which is detrimental to photography and safety), waterproof bag (protect mobile phones and other items that are afraid of water when necessary, and can also be used as a life-saving airbag), watch (bring accurate altitude and A compass is the best), a telescope (20x is enough), a map, a lighter (just pick it up in the departure hall after you get off the plane), fruit juice (drink some every day to balance electrolytes), multivitamins, Diarrhea Stop, a I won’t tell you a communication notebook (this will be important when your phone is soaked in water or lost), batteries, cameras, jackets, underwear, hygiene products, etc. What you need to pay attention to is to do your homework in advance and understand the route conditions. Try not to go to places you know well (it will delay the trip and increase the risk factor). There are many people on this road. When the time comes, three or five people can form a team and take care of each other. The locals are very simple, but not all of them like outsiders. If they ignore you when asking for directions, don't feel uncomfortable, it's normal. What you need to be careful of are the foreigners hanging out there (I won’t mention the specific places), especially the extremely enthusiastic ones. Tourists are the fat in their eyes. The financial situation cannot be estimated. Depending on my specific itinerary and wishes, I will never go to a place that sells tickets. Remember: safety first!
