Dìxià Chéng ("Underground City") is a network of bunkers covering around 85 km² under Beijing where 100k to 1M people live. Where can I find a map of it? E.g., tunnels, entrance points, facilities, etc.

  • Underground City has been closed for renovation since at least February 2008. From your Wikipedia Link. I'm not from Beijing but you'd better double check if it's still open. (And if it's not, please also edit the WP page to update it)
