I found this blog, (actually while searching for other information LOL funny how that happens), about a trip to the hutong district in Beijing. I won't spoil the surprise - go read - and there is also lots of other interesting background information about the houses and the area as well. Enjoy. China Trip 2009
Actually take a stroll forwards and backwards through the rest of the blog - as some one interested in Jackie, China and Beijing - it is a really interesting look at some of the sights of Beijing.
