ps. This is the only morning I saw blue sky since I arrived a week ago, thanks to the downpour last night. I enjoyed working with my colleagues here very much, and I had loads of fun meeting old and new friends. (Don't be upset if I didn't get to call you or meet you during this trip, my old friends. I will try when I return in a few months.) I don't like the noises or dusts while walking to work, and I think the government can take care of the dirty streets at least, if not the other things. I wish for a better China, and I wish for world peace.
