The Peking Medallion - Robert Stack (1967) - Siu Sau, Tuen Mun

The final scene in the film, as the remaining characters make a dash for the Hong Kong border while being pursued by Communist soldiers, was filmed out in a small place called Siu Sau in Tuen Mun District.

The latter picture is the view from - at a guess - where Jade Grove now stands. I initially thought the flat bit in the distance was the area now filled by the Palatial Coast development, but I have checked the aerial photos and now know it to be the area where Peridot Court stands. The farmland right close to the beach, centre right, is where Tsing Lung Garden now stands.
