What's the weather like in Tianshan and Kanas in Xinjiang in June? How to dress?

Kanas is quite cold. I have just been there, and I managed to spend the night with two thick quilts and electric blankets. The yogurt was frozen into ice cream the next morning.

You should take a thick coat, but you don't need a down jacket. You'd better take a shawl, put it on when it's cold and take it off when it's hot. No trouble.

Tianshan Mountain is generally cold, but you should also bring a thick coat.

Be sure to bring an umbrella and sunglasses! Umbrellas are used to prevent rain, and it will rain in the mountains in summer.

Xinjiang is very beautiful.
