Okay, I'm cheating a bit because this isn't Ocean Park per se, just the body of water next to it outside of Aberdeen Harbour.
Once upon a time, until about 10 or so years ago (2001 to be precise) the Aberdeen side of Ocean Park - at the bottom of those rather impressively long escalators (much more impressive than the mid-levels one at least) was a part of the theme park that was given over to ancient China. It was called Middle Kingdom and consisted of some Imperial looking Chinese buildings around a central square. On my first trip to HK I did actually go here and stayed to watch the so-called kung fu demonstration - basically a bunch of guys doing the standard chikung tricks: bending bars in their throats, throwing chopsticks into a target board and walking barefoot across supposedly razor sharp knives.
Anyway, to cut a long story short, you can see the old buildings of the Middle Kingdom in the background of the following screen shots. The top one shows what looks like a temple at the top left but it was just a cheap imitation that, seemingly, wasn't popular with the burgeoning Mainland masses.
