Archaeologists have discovered more than 1,000 pieces of relics at six newly unearthed sacrificial pits at the Sanxingdui Ruins site in southwest China's Sichuan Province. One of the most impressive findings so far has been the remnants of a 3,000-year-old gold mask, with the outlines of ears and mouth intact. Among a large number of heritage sites and cultural relics across China, the Sanxingdui Ruins site is considered one of the most important ancient treasures in the world for its vast size, age, and rich cultural content.
