/kloc-how cold is the climate in Gannan Tibetan Autonomous Prefecture in mid-October? It's below zero

There is a great temperature difference between day and night. It is very hot at noon.

Be sure to bring a thin sweater and coat, preferably a waterproof coat. The air there is humid and the dew is heavy in the morning.

Bring one or two long-sleeved T-shirts or shirts.

If you are in poor health, you must bring woolen pants. It is really cold in the morning. If you are in good health, you should have enough pants.

Gannan is a good place. Good luck!
