City on Fire - Chow Yun Fat (1987) - Chung Pak Commercial Building, Yau Tong Industrial City

The venue for the jewelry factory heist is the Chung Pak Commercial Building on Cho Yuen Street. The place looks pretty much the same even today although it appears to have been recently repurposed into the "Chung Pak Health Care Services Complex" and given a bit of a face lift.

Here's the thing though. Although the heist scenes were filmed here in Yau Tong, the police approach and subsequent violent shootout and explosions were filmed in a completely different location (and one that I have yet to identify) although Ringo Lam shot the scenes and had them edited seemlessly together so it's difficult to see the join.
