The second clue comes from the background in the other direction. As Xiao Rong enters and leaves the property, we catch a glimpse of the roof of a property behind. It's quite a distinctive roof and, thankfully, is still around today. It belongs to the former "Air House" located at 1a Cornwall Street (the same building that was captured on camera in this post).
Sadly the property at #20 has changed significantly over the years and it was just recently demolished and completely rebuilt into a new building. What's interesting about this place, and you may already know this if you ever read my old, now deleted, history blog, is that it was the private house of infamous heroin kingpin, Ng Sik-ho aka "Limpy Ho".
Coincidentally (or not), Ho was convicted for his crimes in 1975, the same year this film was made, so it's quite possible the house was available for filming once it had been examined by the people investigating his crime. I have no idea who owned it at the time. In a later incarnation it was turned into a "Love Motel" (called the Kent Motel, I think?, the Chinese name was 根德小築) much in the same way as Bruce Lee's old house was. The owner basically filled in all the open spaces of the property (that can be seen in the screecaps) and turned it into a big rectangular block with maximum interior space (for max profits/usage) and operated it until around the time that COVID hit. Following its closure the building was demolished and redeveloped.
The house at the rear is 1a Cornwall Street
