China has announced major archaeological finds that could shed more light on its ancient civilization. So far, more than 500 additional artifacts have been discovered at the site in Sanxingdui, just outside Chengdu in southwest China's Sichuan Province. They include gold and bronze statues, masks, and other articles, as well as jade and pottery.
