Thankfully, the film makers seem to have taken their camera into the Walled City itself and put them up on the rooftops in order to get the following shots.
These first two shots give us a view from the top of Kowloon Walled City towards Nga Tsin Long Road (this is where we were in the last post) in Kowloon City - it's the road with the red shop awnings. The tree covered area is the previously mentioned dispensary.
A little later in the film, when Joji goes back to where his brother was killed, we get another similar view but of the area that is off to the right of these shots.
This first screen capture above shows the dispensary area on the far left of the screen and the white building in the centre is Chi Kam Court (built 1981 - virtually brand new when this film was made!) on the opposite side of Hau Wong Road. It's not white anymore...
The next building with the brown rectangular pattern is the end of the Victory Building that fronts Lion Rock Road. It is also still around and isn't that clean anymore either :-)
The shanty town is long gone - as is the Walled City - the whole area being turned into one large park area encompassing Carpenter Road Park and the Walled City Park. Incidentally the Kowloon City Plaza has also been built on Carpenter Road right in that space in front of Chi Kam Coiurt and the Victory Building.
