Your adventure is quite difficult. Dude, the equipment must be complete and good, or you will feel sorry for yourself! At least 3 people will travel in a team, and the mobile phone will bring a few spare batteries.

A complete set of double-decker tents (tent+moistureproof mat+tent lamp+mosquitoes are afraid of water, etc.)

Mountaineering bags over p>6 liters (brands you choose)

2-3 vacuum kettles. Use a bottle filled with high-alcohol liquor (which can be drunk or disinfected when injured)

compressed food and canned food (chocolate, biscuits, mustard tuber and other favorite energy-compensating foods)

outdoor camping survival tools (walkie-talkie, strong flashlight, 2-3 small shovels, field knives or outdoor knives and daggers, 1-2 trekking poles, safety rope, compass and outdoor special matches). Hehe, then I wish you a good time!
