I went to Zhouzhuang ancient town a few weeks for a day trip. It takes just an hour or so by bus from Shanghai, and because of that it’s extremely crowded on the weekend and also very commercialised. There’s also not many indoor attractions and museums to visit, just a lot of shops. The town is just 10km from Tongli which I thought was much more picturesque and authentic so you might as well just go there, although I haven’t been back since it got connected to the Suzhou metro. I want to go back to Anhui for a weekend sometime, as I really enjoyed visiting the old towns there a few years ago.
