Located in the Yangtze River Basin on the south-eastern coast of the country, the archaeological ruins of Liangzhu (about 3,300-2,300 BCE) reveal an early regional state with a unified belief system based on rice cultivation in Late Neolithic China. The property is composed of four areas – the Area of Yaoshan Site, the Area of High-dam at the Mouth of the Valley, the Area of Low-dam on the Plain and the Area of City Site. These ruins are an outstanding example of early urban civilization expressed in earthen monuments, urban planning, a water conservation system and a social hierarchy expressed in differentiated burials in cemeteries within the property.
