Dirty Tiger, Crazy Frog! - Sammo Hung (1978) - Chong Ha Ching Sze, Fanling

Here's another location that I spent a significant amount of time tracking down for my Snake in the Eagle's Shadow posts. Since then it has popped up a couple of times (quite recently with this Dragon's Claws post). Once found these places are fairly easy to subsequently recognise. In this film, this old building is the brothel where Frog and Tiger go to lure the Coffin King's henchman into a trap.
