Thanks guys...just came from my doctor this morning to get my sinuses cleared. He said Beijing would be extremely cold and I need masks to avoid my face from drying and I pretty much might end up just in my hotel room. I'm going there around the 11th of January just a week before CNY...is it going to be this cold??

Haven't been to Chicago during winters...I absolutely have no idea how cold it could get. I tried googling images of Beijing in January and its really a mix of overly wrapped tourists and jacket clad locals.
