The Forgotten Liangzhu
(被遗忘了的良渚)
5 min read
Over half a dozen Neolithic cultures once dotted the vast expanse of what is now China, particularly along its two great river systems—the Yangtze (长江) and the Yellow (黄河) Rivers. The ruins of Liangzhu (良渚) were first identified in the 1930s, when jade artifacts were unearthed during road construction. In the decades that followed, thousands of exquisitely refined jade relics were discovered.
Named after a local community near present-day Hangzhou (杭州) in the Yangtze River Delta, Liangzhu stands out as one of the most advanced late Neolithic cultures in the world. Archaeological dating places Liangzhu between 3300 and 2300 BCE. In recognition of its global significance, the site was designated a UNESCO World Heritage site in 2019. The Yangtze Delta has long provided a favorable environment for settled agriculture, from ancient times to the present.
The Liangzhu ruins encompass a constellation of sites. Across the Yangtze Delta, archaeologists have identified more than 600 Liangzhu settlements. In 2006, excavations revealed the largest and earliest known walled city in ancient China. The city features remnants of massive walls, an inner and outer city spanning a combined area of 6.3 square kilometers, an extensive network of natural and artificial waterways, and cemeteries from which more than 4,000 jade objects have been excavated.
With a total of approximately 30 kilometers of canals, Liangzhu was a city of waterways as much as roads. No evidence of pack animals has been found, suggesting that canals were essential for transportation, trade, and the movement of construction and agricultural materials.
Archaeological discoveries at Liangzhu suggest that it represents East Asia’s earliest state-level society. At the heart of the city lay a palatial precinct dominated by an immense, man-made trapezoidal earthen mound. Liangzhu’s sophisticated system of dams, levees, and reservoirs—used for flood control, irrigation, and water storage—is the earliest known large-scale water management system in the world. These remarkable urban and hydraulic infrastructures point to advanced engineering knowledge, highly organized labor, and a strong centralized authority.
Liangzhu’s water management system enabled effective irrigation of rice fields and control of flooding, producing food surpluses sufficient to support a large population. One excavated granary alone contained more than ten tons of carbonized rice. At its peak, the city is estimated to have supported a population of around 35,000. Vernon Scarborough, professor of anthropology at the University of Cincinnati, observed after visiting the site: “There’s nothing in the world…that is as monumental in terms of water management—or for that matter, any kind of management—that occurs so early in history. It’s an engineered landscape that is second to none, given its antiquity.”
Despite being among the most advanced late Neolithic cultures in the world, Liangzhu collapsed abruptly around 2300 BCE. Paleo-climatic and archaeological evidence suggests that this decline occurred during a short but unusually wet period, likely resulting in catastrophic flooding. Liangzhu’s reliance on rice agriculture made it especially vulnerable to inundation, leading to food shortages. Human skeletal remains from this period show signs of malnutrition, violence, and a disproportionately high number of younger individuals. The conspicuous absence of jade objects in these later burials suggests a depletion of resources and a breakdown of social order. Over time, Liangzhu’s significance faded from memory, though its former grandeur remained buried beneath the landscape.
Because Liangzhu lacked a writing system, no textual records of its history survive. Much of what we know comes from burial jade objects. While many tombs were modest and contained few grave goods, others were richly furnished with jade artifacts of exceptional refinement, indicating a pronounced social hierarchy. Like silent storytellers, these relics reveal the beliefs, social structure, and technological sophistication of a society that flourished five millennia ago.
Many Liangzhu jade objects feature intricate motifs, including animal masks or so-called “divine faces,” believed to represent deities or supernatural beings. The placement of finely crafted jade in elite burials underscores its role as a symbol of power, authority, and ritual legitimacy. The advanced techniques of carving, drilling, and polishing required metal tools, while the abundance and standardization of jade objects reflect organized labor and centralized governance. Because jade was not locally available, its presence also points to long-distance trade networks.
Although Liangzhu collapsed, its cultural legacy endured. Elements of Liangzhu culture—especially jade forms and iconography—spread to later Neolithic and early Bronze Age cultures, including Sanxingdui (三星堆) and the Xia. This diffusion was likely facilitated by China’s extensive river systems, which enabled the movement of goods such as jade, pottery, and agricultural products. Climatic shifts toward the end of the Liangzhu period may also have driven migration, further disseminating its technologies, traditions, and farming practices.
While the later Shang Dynasty (商) is best known for its complex political system, Liangzhu predates it by nearly a millennium and stands out for its advanced urban planning, social organization, water management, and artistic achievement. It represents a foundational culture in the long development of Chinese civilization.
Liangzhu’s early state prototype is evident in its monumental waterworks—dams, reservoirs, irrigation systems, and canals—which required centralized planning and management. The city’s clear spatial organization, with a palatial core, residential districts, ceremonial platforms, and craft-production zones, demonstrates an early form of urban design. Richly furnished elite tombs reveal sharp social stratification, while the ritual use of jade laid an ideological foundation for later Chinese traditions in which ritual authority underpinned governance. Liangzhu’s intensive rice agriculture generated surpluses that sustained dense populations and non-farming elites. Together, these features challenge the long-held Yellow River–centric view of early Chinese civilization, highlighting instead a pluralistic process shaped by multiple regional centers.
Today, the Liangzhu City ruins and excavated artifacts are displayed at the Archaeological Ruins of Liangzhu City Park (良渚古城遗址公园) and the Liangzhu Museum (良渚博物院). Located within easy day-trip distance of Hangzhou, Suzhou (苏州), and Shanghai (上海), the museum houses a comprehensive collection of Liangzhu artifacts, including jade relics, stone and pottery tools, and other archaeological discoveries.
