Speaking of the origins of Green Lake, it was actually part of Dianchi Lake. In the ancient water conservancy project, the water level in Dianchi Lake was reduced, and the Green Lake, which is now separated from the main body of Dianchi Lake, was formed. Because in the past there were many rice gardens in the lakeside, so in the old days people called it "cabbage." Many warlords and administrative officials who have been to Kunming in history have built houses in Cuihu Xiuting.
