The Lady Professional - Lily Ho Li-li (1971) - Kowloon Wharves

The contract to kill Shi is subcontracted out to the boss of the guy who is blackmailing Tian-li. They are based in a warehouse at some wharves somewhere. The establishing shot shows us the Kowloon Wharves but in the close ups of the warehouses/godowns, it looks like that was filmed elsewhere (possibly even Movietown). This image is a stitch from a panning shot of the area. This area is now all part of the Harbour City mall complex.
