Sanxingdui Site – The Origin of the Yangtze River Civilization, a Site That Shook the World.
Located on the south bank of the Yazi River in Guanghan City, Sichuan Province, the site covers an area of 12 km², with the core ancient city covering approximately 3.6 km². It is the largest, most complete, and longest-lasting ancient Shu capital site discovered in Southwest China to date.
Latest Archaeological Progress (to be released in 2025):
Precise Dating: Sacrificial pits 3, 4, 6, and 8 have a 95.4% probability of dating to 1201–1012 BC (Late Shang Dynasty). Artifacts from pits 1, 2, 3, 7, and 8 can be pieced together, confirming they were buried at the same time.
New Casting Techniques: The "core-strip core support" bronze casting method was discovered for the first time, filling a gap in Chinese Bronze Age technology.
Gold Usage: The total weight of unearthed gold artifacts exceeds 2 kg, the highest in China for the same period; gold masks and gold foil ornaments were refined using a gold-silver alloy and ash blowing method.
Silk Traces: Silk residue was detected in multiple sacrificial pits, proving that people wore gold and brocade 3,000 years ago. Key artifacts: A large bronze mask (131 cm wide, weighing 131 catties, the world's largest Shang Dynasty bronze mask); a gold-masked bronze human head (42.5 cm, made from gold-plated wood, with openwork eyes and eyebrows); and over 5,000 other artifacts including a bronze sacred tree, a bird-shaped bronze bell, ivory carvings, and jade cong, showcasing the unique cosmology of the ancient Shu Kingdom.
Sanxingdui buried the ancient Shu Kingdom's gold mask, bronze sacred tree, and silk sacrificial robes in late Shang Dynasty sacrificial pits. Their discovery today serves as the most dazzling evidence that the Yangtze and Yellow Rivers are both part of the mother river of Chinese civilization.
