The Spring and Autumn Yancheng Tourist Area was built on the basis of the Spring and Autumn Yancheng Site. Yancheng was a surface city pool of three cities and three rivers during the Spring and Autumn and Warring States Periods. Archaeological evidence shows that it has a history of more than 2700 years. It is the most complete and unique site of surface city pool of Spring and Autumn in China. The site is 850 meters long in East and west, 750 meters wide in North and south, and has a total area of about 650,000 square meters. There are more than 1000 precious cultural relics unearthed in the site, including 4 canoes, 20 bronzes and a large number of primitive celadon and pottery. Canoe models are displayed in the park. Three cities and three rivers are restored according to the original surface, sitting on the elevator of the park, rising to the highest point, overlooking the city pool below, surrounded by water.
