Now the challenge: Name that location

[FGZ*] Bryce3D?

The shape of the bay looks a bit like Rio.

Nope. I'll tell you that it's in Asia.

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???
