How cold is it in winter in Yili, Xinjiang? What level of down jacket should I wear?

Hehe, it's not that exaggerated. It's about MINUS 20 degrees. It is not as cold as Urumqi. An ordinary down jacket will do. The weather in Bosideng is good and the air is good. Down jacket, woolen coat, thermal underwear and woolen sweater are enough to wear. Welcome to Xinjiang. I hope you will like it here ~
