People always wonder how you can squeeze more than 7 million people into the tiny place known as Hong Kong.
Here is a night view.
You will also see roads doing a zig zag, pedestrain links connect at a higher level or flyover snaking through the available space at an upper level.
Also in the picture is a railway depot where rail lines terminate.
It has always been a busy city, even at night time.
It is truly a city of lights!
