Great lakes witness-the green development road of the three major freshwater lakes in the Yangtze River Delta.
Overlooking the Yangtze River Delta from the map, the criss-crossing rivers and lakes make this highland of China's economic vitality and innovation more agile and beautiful. Taihu Lake, Hongze Lake and Chaohu Lake are just like three gems dotted on them.
From dirty rivers to clear water and beautiful coast, from "water control in Kowloon" to joint management, from exhausting water and fishing to harmony between people and water ... People who live by water for generations have personal experience: focusing on the long-term and protecting one side of clear water is the premise and foundation of "eating by water".

Dianchi Lake is a plateau lake, facing the problems of insufficient water, stagnant water and dirty water, while Chaohu Lake has both. " Zhu Qing, president of Chaohu Research Institute, said.
