For washing: it is best to bring two bath towels. I'm afraid I used one and didn't do it the next day. Girls had better bring a toothbrush, toothpaste and a towel for washing their faces. If you are afraid of wasting paper towels, you can bring some sweat towels. Girls should bring combs (mirrors with them) and hair bands (remember to bring more hair bands). Don't forget to bring shower gel and facial cleanser (you can bring facial cleanser if you are a boy). Shampoo and laundry detergent (no laundry detergent is needed if you don't wash clothes), slippers (slippers are very convenient when you must bring them), buckets (which can be used to hold hot water), and bath flowers (the kind that can produce a lot of bubbles, depending on whether you need them).
Food: eight-treasure porridge, water (if you are not afraid of the weight, it is very expensive to buy water there), sausages, biscuits (you can eat some energy and nutrition when you are hungry), milk (you can drink a bottle every morning), sugar (you can also bring some sugar if you are greedy) and chocolate (you can add some energy if necessary).
(food summary: these are all based on my own preferences, not necessarily based on these. According to individuals)
Clothes hangers: large clothes hangers can hold 1~2 (bath towels can be hung), ordinary clothes hangers can hold 4~5 (one for clothes, one for trousers, two for military use (one for clothes and one for trousers), and small clothes hangers can hold three (underwear, underwear and socks) and several clips (socks).
Drugs: mosquito repellent (there are many mosquitoes in the mountains, so it is best to rub some on your ears before going to bed, because mosquitoes will buzz around your ears at night, on your legs, feet and arms), band-aid (it is easy to get hurt in military training), stomach pain medicine (for fear that you will get indigestion there if you can't eat it), mosquito bite medicine (actually mosquito repellent is enough), throat lozenges (shouting slogans will hurt your throat), etc.
Drug summary: (Well, I suggest you take some vitamins, because almost everything there is nutritious)
Electrical appliances: MP3(MP4, MP5) mobile phones, batteries (these can be brought if you are not afraid of confiscation. Hide as soon as the instructor comes. Take a few more batteries, and there will be no place to charge. Flashlight (it's dark when going to the toilet at night, so people who are afraid of the dark must bring it), small alarm clock (you can set a small alarm clock for fear of not getting up in the morning), small fan (there may be no air conditioning there), and watch (with or without it).
Others: paper towels (you can bring a packet of paper or a few packets of small toilet paper), money (about 50, not too much), pens, notebooks (maybe the instructor will let you write ideas), locks (be sure to bring them, there will be people stealing things), books (you can read them when you can't sleep at night), and girls can also bring a small doll and poker (when you are bored).
