Archaeologists started a new round of digging at the Yejiashan Graveyard on Wednesday, which was believed to have belonged to lords of the Zeng State during the early Western Zhou Dynasty (1046-771 BC). First discovered in 2011, the Yejiashan Graveyard was inscribed among China's Top 10 Archeological Findings that year. More than 700 pieces of crockery, bronze wares, lacquerwares and jade have been excavated from the tombs. (Xinhua/Xiao Yijiu)
