Hmmm... That looks like a fair-sized city -- and I have been to a lot of cities in Asia but don't recognise this one. I don't think it's Hong Kong. But there are a lot of large cities in China that I've never seen, so I wonder if it might be one of those. I'm also a bit bemused by what is in the left of the picture: a rollercoaster???
Yep, it's the run-away mine train at a theme park which I visited. Sadly this particular roller coaster was closed for maintenance on the day. It looks like fun, too.
