The East Lake is located in Mapeng Town, Gaoyou City, 12 km from the city proper. Herding wild ducks, a stunt well known throughout the world, has added to the East Lake's fame.
A group of wild ducks are slowly swimming on the quiet lake surface, coming and going in groups on the water with words of command from a herdsman, Lu Gaozhong. CCTV's program Oriental Horizon once made a special program entitled "Persons Breeding Wild Ducks".
