One of China's most important archaeological discoveries of the 20th century, the ruins located on the upper reaches of the Yangtze River serve as convincing proof that the origins of Chinese civilization are diverse, as it rejects theories that the Yellow River is the sole origin, according to Duan Yu, who is a historian with the Sichuan Academy of Social Sciences.

Archaeologists hail the Jinsha Ruins as one of Sichuan's most important archaeological findings since the discovery of the Sanxingdui Ruins.

On Feb 8, 2001, builders working on an apartment construction site in Jinsha village in Chengdu found ivory and jade pieces among piles of earth.

Since then, archaeologists have excavated more than 10,000 relics including gold, jade, bronze and stone wares, as well as one metric ton of whole elephant tusks and tens of thousands of pottery and ceramic shards.

Jinsha is known as one of the country's most prolific excavations in terms of gold and the number of artifacts unearthed. It is also one of the world's largest excavations of ancient elephant tusks, Zhu says.

The Jinsha Ruins are most likely to be the political and cultural center to which the ancient Shu state moved from Sanxingdui about 3,000 years ago, says Zhu, who has been an archaeologist since his participation in the excavation of the No 1 and No 2 pits of the Sanxingdui Ruins in 1986.

As a matter of fact, both the Sanxingdui and Jinsha ruins are closely related. The National Cultural Heritage Administration is promoting their joint application for inclusion on the UNESCO World Heritage List, Zhu says.
