Hillside Grave in New Territories-1958

One of many graves scattered  around the hillsides in New Territories,l took this photo while out on tank training exercise with 1st Royal Tank Regiment (photo dated Feb 1958) recognise the area in background as Lowu tank training area.? Would these be the graves of prominent people in Chinese community, or maybe the actual owner of the land?. I do know the soldier on right hand side,”Ginger” Bolton as his bed was next to mine in hut 41 at Sek Kong.
