What should I prepare for my trip to Harbin?

I'm from the south, and I just got back from there. I think the necessary things are: gloves-preferably two pairs, one with thin fingers and one with thick fingers; Hat; Scarf; Mask; Chilblain cream; Wear two pairs of socks; Down pants; I have to wear more clothes, but I wear two pairs of velvet pants; Don't wear eyes; It's so dry there, prepare a mask; You should bring lotion and other moisturizing things. There are no camera batteries, so you'd better take two. Almost. If you don't understand, you can add it.
