Willow Lake is in the northeast of the ancient city of Changde. It is named after tree because of its shape. Baihe Mountain, Huashan Mountain and Sun Mountain surround the northern part of the lake. Baihe Mountain is a treasure, where white cranes live. Every season, many white cranes and egrets arrive. They fly in blue skies over clear water, adding wonderful colors to the Willow Lake. The vast water of Willow Lake is ideal for water sport competitions. A water course has been built, and many events are successfully held.
