Those of with sharp eyes and a good memory will remember a similar view from when I was posting about Shatter, and if you page to the bottom of this post, you'll see the same raised lip of earth around the corner of the Shatin Pass Road that can be seen in the first shot below.
The large housing estate that can be seen in the top picture is the old Tsz Wan Shan housing estate that was demolished over a period of time throughout the 1980's and 90's and replaced by smaller clusters of separately named estates. The flat area in front of the shaved hillside is roughly where today's Po Kong Village Road Park Football pitch now stands - the rest of the hillside has been pretty much completely removed.
In fact, on the other side of the hill is where the Tate's Cairn Tunnel now pops out right next to Chi Lin Nunnery and Nan Lian Garden. As far as I can tell, about the only buildings that can be identified that are still standing are three blocks that line the Po Kong Village Road in the bottom left of the top picture. The leftmost is a CLP substation and the other two are actually schools which may go some way to explain why they are still around.
