There's a real mixture of locations seen here, some of them not really seen on international film productions before, one of which is a brief snippet during the explanatory introduction when an image of a local school is flashed up. You can't necessarily tell from the image but it's the Yuen Long Public Middle School Alumni Association Primary School. As you can see, it's keeping in the Hong Kong tradition of having an unnecessarily long English name.
It's irrelevant to the film really but I was intrigued to track it down. Finding it goes some way to explain why Yuen Long District Office gets a special thanks in the end credits.
