Wonderful wetlands serve to inspire city dwellers

The heart of a city to some people is the central business district where people live in the hustle and bustle.

Or to others it can be the architecture of various landmarks which to them embody the city's spirit. But in Guangzhou, its people call an area of wetlands their "green heart".

On sunny weekend mornings, when the mists over Haizhu Lake gradually disappear, it is easy to spot birds spreading their wings and flying high into the sky.
