Liangzhu site can prove the 5,000-year-old civilization of China. Liangzhu culture named after Liangzhu site is 5300-4300 years ago, and this site is also the embodiment of Chinese civilization. Liangzhu site was first discovered in 1936, and it has been truly and completely preserved to this day, which can prove the high achievements of rice farming in prehistoric society in the Yangtze River valley of China 5000 years ago and fill the vacancy of Neolithic archaeological sites in East Asia in the World Heritage List. Liangzhu culture, with its highly developed social productive forces, obviously divided social classes, cohesive and unified beliefs, and the right system of the integration of gods and kings, especially the emergence of urban civilization, has already possessed an early state form.

After decades of rescue excavation, a large number of gray-black pottery, jade cong, jade bi, jade yue and other jade articles have been unearthed in Liangzhu site. In 2007, the ancient city of Liangzhu, covering an area of 3 million square meters, came to light again. The complicated water conservancy system, mature rice production, unified cultural beliefs and divided social classes present the material civilization and spiritual world of an ancient civilization and the 5,000-year history of Chinese civilization. The planning pattern and construction technology of "Water City" displayed in Liangzhu ancient city site reflect the urban and architectural landscape created by people in wetland environment. Especially as an urban water resources management project, the peripheral water conservancy system also shows a rare scientific level in the world in terms of project scale, design and construction technology.

In 20 13 and 20 17, Colin Lunfuru, an academician of the Royal Academy of Sciences and a famous professor of archaeology at Cambridge University, made two field trips to Liangzhu site and visited Liangzhu Museum. He believes that Liangzhu site is a model for the protection of great sites in China, and puts forward that Liangzhu dam site is probably the earliest dam in the world. "The Neolithic Age in China is an era that is far underestimated. The complexity and class system of Liangzhu site have reached the standard of "state" and are the origin of Chinese civilization.
