What should I bring when I travel for about three days?

Necessary for outdoor travel: documents that can prove identity, such as ID card, student ID card, work permit, etc. Lip balm is indispensable. When traveling in dry areas (such as Jiayuguan, Dunhuang, Turpan and Tibet), you can avoid the pain of chapped lips and bleeding. Swiss army knives or small scissors and tool knives are essential tools. Fruit knife: Long-distance travel must often eat fruit and supplement vitamins (especially in desert and plateau areas), so fruit knife is indispensable and also a self-defense tool. Small flashlight: The small flashlight will play a powerful role when the long-distance bus stops for dinner, relieves itself or breaks down at night. At the same time, visiting night markets, hotels, unexpected power outages at night or going to places without electricity are also inseparable from small flashlights. Bring your own spoon: Restaurants that stop by bus and restaurants in backward places usually have no hygiene guarantee, so spoons have their own uses. If you go to Xinjiang and other watermelon-rich places, spoons are even more indispensable. Military backpack belt. Cheap hotels rarely have clothes hooks for hanging clothes and towels, while small backpack can hang clothes and towels in the room, which is both sanitary and convenient. At the same time, climbing mountains and tying luggage can also be used frequently. There are three to five spare plastic bags, which can be used to collect wild fruits, place food and newly purchased items. If you travel to Tibet, cold medicine and anti-hypoxia medicine (such as rhodiola capsule) are the most commonly used drugs. Notebook, write down feelings, events or mailing addresses at any time. Tissue, often used. Camera and film. Maps, mineral water. Sunglasses, without them, it will be difficult to open your eyes when climbing a snowy mountain in the sun. Ultraviolet rays in Tibet are very strong. Take emergency medicine with you, which varies from person to person.
