What should I pay attention to when traveling to Yunnan?

First of all, it is cash. Of course, carrying a lot of cash is not safe, but we can't just consider insecurity. Because you are a stranger when you are in a hurry to pay the bill, you may worry that you can't find a bank or ATM, so bring a credit card with you on the premise of bringing some cash. ID card, necessary to go out, needless to say; Mobile phones, cameras and equipped batteries and chargers; Paper towels, wipes, handkerchiefs or towels. Even if you stay in a hotel, it is recommended to bring your own toiletries (such as toothpaste, cream, facial cleanser, shower gel and shampoo, preferably with samples). If there is no sample, you can buy an empty small cosmetic bottle to hold it. In addition to underwear, it is generally enough to change a set of clothes and pants, and it is best to bring a thin coat (the temperature difference between morning and evening in Yunnan is large); It is recommended to bring a portable pen and paper, and if possible, it is best to have a small Swiss army knife (it is convenient to replace many tools, of course, it is not a necessity, just get ready); Chewing gum, cooling oil, stomach medicine, VC (this is to prevent colds), and other medicines do not need to be brought, because there are pharmacies everywhere, which are not necessarily needed, but will increase the burden; You must bring sunscreen, hat, sunglasses and a folding umbrella. In addition, it is best to bring a bottle that can hold water, because the water in many tourist attractions is very expensive.
