The lake has four sections and is larger than West Lake, Hangzhou. It is currently a 4A site classified as such on cultural heritage due to its connections with Fuxi, Confucius and the I Ching. It has 10 separate mentions in the I Ching. It is wholly fresh water and tightly controlled to sustain the environment with no swimming, or powered boats permitted. Fishing is from permitted land bases only although there is a short season of less controlled fishing for culling. Shore line activiities are also tightly controlled. It hosts over 30 species of birds and has more durnig the migratory season. Tourists can take a lake boat trip on an electric powered boat. The lake is broken up by several reed beds. During the Japanese occupation in the 1930s the lake was well relatively well protected due to its heritage value. It is possible to drive around the lake and modern management alos seeks to minimise water degradation from run-off off the road during wet weather. The boat trip is a relaxing trip offering photographic opportunities and takes about an hour. The Lake area is a location for bird watchers and has viewing areas for that purpose. Plans are being progressed to launch an application for 5-A classification - the highest grade in China
