Farm property near Hong Kong

To the best of my knowlege, this photo was taken at the farm property of my grandfather, Tobias Hunter, somewhere near Hong Kong. I recall being told that the property had a small lake, possibly man-made, and that he often held parties or outings for orphaned children. The exact location is unknown but I think it may be quite near to Hong Kong or Kowloon. The photo was taken about 1917.
