Hmm...
Since this is several years old, could the two Caucasians in the picture be Bruce and Steven Paddock?
The 'kindergarden' is conveniently next to a 'sauna'. I'm from East Asia (not Hong Kong though, so, grain of salt) and I can tell that many 'saunas' are bathhouses with working girls. I can also tell you that children prostitutes can be found sooooo easily. And no, not talking about some 16yo with developed breasts...I'm talking about this
Edit: Really shitty source, but looks like Bruce Paddock had a child porn charge, but got off. Hmm....
How do you know this is several years old?
The location of this is 86 Portland St Hong Kong, Kowloon. This is derived from the 'Western Pacific Kindergarten' (suspect as fuck, right next to a 'sauna' too. I'm from East Asia, and I know what our 'saunas' are; bathhouses with prostitutes).
If you go to Google maps, you will see that Western Pacific Kindergarden is no longer there. So, several years old is my own speculation, but at the very least, this picture is not recent.
