The Generation Gap - David Chiang (1973) - To Fuk Road, Kowloon Tong

Cindy lives with her parents at a property accessed from what is now To Fuk Road. I'm not sure how old this road name is because older maps don't show it and this was not the throughfare it is today, but more of a side street from the main estate. The entrance to the house tells me that the property was #10 Norfolk Road, although this was a side entrance as the main entrance is on the aforementioned Norfolk Road side. This property, like many others in the area (though not as many as there once was) currently operates as a Love Motel.

The first image we see is of Cindy walking home with her friends. The lower wall behind them belongs to 13 York Road and remains to this day although it has had some additional height added to it, the original section can still be recognised. Here is the current streetview for context.

Later in the film we get to see in the other direction as Ling Xi's brother (played by a bespectacled Ti Lung) tricks Cindy into going home and a fight breaks out between the two brothers next to the railway track. Note the no entry signs at the end of the road. These mark the boundary of the Military area that was located there. I believe it was the former Ordnance Depot of the army and contained St George's School, a UK army school for garrison children.

The scenes where Ling Xi climbs up the side of the house to Cindy's bedroom though, I believe these were shot at Movietown on a specially constructed facade. The house facade in the movie looks a bit too slapdash to have been real, and the environment doesn't look right for Kowloon Tong.
