Bullet in the Head - Tony Leung Chiu-wai (1990) - Kiu Shing Street, Yuen Long

This small industrial estate in the Ping Shan area of Yuen Long will be familiar to anyone who has seen Police Story 2 as it's the location used in that film for the exterior shots of the bad guy's initial hideout. Here's a reminder. In Bullet in the Head this is the location of the factory where Ben's girlfriend/wife works. It's the same location seen later for the riot scene as Ben and Jane say their farewells just before the story shifts to Vietnam.

In reality it's the Ying Cheong Industrial Building. This following Google Maps link shows a view from 2009 where most of the buildings still looked as they did in the movie. However, it should be noted that the left hand side has since been redeveloped.
