Yongkang District is located on the formerly Taijian lagoon area (inland sea) with make lakes and bridges. The most famous lake is called Jiyu Lake. It was the Dawan Strait in the ancient time and became a lake when a lagoon was formd after a land uplift. The lake located in Yongkang District has three names, Jiyu Lake is one of them for the lake’s high yield of the crucian carp (Carassius auratus). The second name is Dong Lake for its location in the east of the prefecture. The third name is Long Lake for the location of the dragon according to geomancers. As a never-dry lake, it is an important irrigation source in Yongkang. As the lake never dries out, it is an ideal place for moon-watching. Known as “Jitan Moon Watchign” or “Longtan Moon Watching”, Jiyi Lake and “Datapi” at the Martial Temple were two of the eight winders in Taiwan City.
