Introduction to Yuhu: Emperor Qianlong visited Qionglong Mountain during his six trips to the south of the Yangtze River. Yuhu was also named Yuhu from an unnamed lake because it was the place where he abandoned his boat and landed. The surface of Yuhu Lake is irregular square, with a total area of 75,000 square meters, a water area of 55,000 square meters, and a deepest depth of 5 meters. The Ambergris Waterfall in the center of the lake is 18 meters high and 45 meters wide. It is the largest artificial waterfall in Suzhou. The lake surface is irregular in shape.
