The makeshift cocaine processing plant is one of the many abandoned, derelict houses which seem to litter rural Hong Kong; here we're on the Sha Lo Tung plateaux, in the hills above Tai Po.
Today it's a double thanks to the wonderful Phil from the always incredible Hong Kong (& Macau) Stuff / Hong Kong (& Macau) Film Stuff blogs. Not only did he spot the location, but also provided one of his own snaps, as this isn't covered by Street View. Thanks Phil!.
