Chinese archaeologists have discovered six new sacrificial pits and unearthed more than 500 items dating back about 3,000 years at the Sanxingdui Ruins in southwest China's Sichuan Province. CGTN's Ji Xiaojun got the opportunity to walk inside one of the six pits and have a closer look at the excavation site. He also sat down with Lei Yu, director of the Sanxingdui site workstation.
