Yarn stores in Beijing?

Does anybody have any info on yarn stores in Beijing? I was in the world trade center (guo mao) shopping mall yesterday and saw a small one, but it was some expensive italian company selling only their own brand… certainly not the type of LYS a beginner like me needs. I’m looking for a place that has a big selection, relatively low prices on at least some items, and offers lessons or at least advice.

look at this! that looks like it has some cool potential and is soon!

edited: not sure if the general public can go though after looking around at it but maybe.
