Seeking location of this photo

This photo was taken somewhere hear Hong Kong or Kowloon about 1917. There is one person in the water swimming, in the lower right corner. There are some thatched buildings in the background on the right side of the picture. The clothing indicates a warm day. I have located my family members in the picture but do not know the exact location. My grandfather had a farm somewhere near Hong Kong, with a small man-made lake or pond on thne property. He used to entertain children from an orphanage there, as well as his own tow children. I am hoping someone might know this place.
