Six more ancient sacrificial pits and more than 500 relics dating back to about 3,000 years have been unearthed at the renowned Sanxingdui Ruins site in Southwest China’s Sichuan Province, the National Cultural Heritage Administration announced in Chengdu on Saturday.
“It has been confirmed that Sanxingdui Ruins site is the oldest site of pre-Qin period (pre-221 BC) in the upper reaches of the Yangtze River,” according to Lei Yu, head of the excavation team at the Sanxingdui site. Experts believe that the new findings at the site will shed more light on the ancient Shu civilization and its link to the civilization of the Chinese nation.
Among the relics, there are pieces of exquisite gold masks, gold foil, bronze masks, bronze sacred trees, ivories, ivory products and jade.
