I ride by this building often; with its beautiful precast concrete fence, red gates, and guards surrounding the place... I often wonder what it is. There are no signs anywhere...
It's at the end of Guling Street, abutting Chongqing South Road, on the way to the Presidential Palace (if you're coming from the south).
I've seen a cavalcade of black cars drive right into the precinct on more than one occasion... so my best guess is that it's the presidential residence? Anyone know for sure?
