I hadn't really done any research about Shanghai, but Greg had, so I he decided (well, it was so easy and convenient to let him do all the decision making in China) we were to go the Zhujiajiao one day. And so we did.
Zhujiajiao is an old channel town with narrow streets. Once upon a time it must have been a beautiful town, and it still is, but has been very turistified, and there is souvenirs everywhere. However, in contrast to other places, they don't yell after you.
