I agree with everyone else. I'm not sure we have any other members from China...so welcome to taperssection battery!
I recently visited Shanghai last October. It was my first visit to China. It was a fun trip, but since I was on business, I couldn't do any sightseeing.
Oh, and I should have mentioned that you have very good English skills. Unfortunately, I'm thinking there aren't too many people here on Taperssection that would be able to speak to you in Mandarin!
