Grand Lake

Tai Lake is a metaphor for the state of Wuxi's development :
primitive accumulation of green algae (Green Buck).
It makes me think of Cuyahoga River in Cleveland,Ohio.
Americans once had a pollution problem in U.S. as well.
The Cuyahoga River used to routinely catch on fire.
In the early 1970s strong environmental laws were passed
and pollution was mostly solved.
