With 3 trips under my belt so far, and another one skedded for this summer...these were a real pleasure to see. I can only imagine how rich and gorgeous they'd be in person.
Not sure when/if you'd go back, but I think you would be amazed by Hong village in Anhui province. The movie "Crouching Tiger Hidden Dragon" was filmed there, and it's a rare thing indeed to see such old, traditional Chinese architecture unscathed. Again, I can only imagine what some finely-crafted Plat/Pall. prints from there would look like.
