Archaeologists work at the No. 3 Horse and Chariot Pit near the city of Xinzheng, Central China's Henan province, June 15, 2017. Archaeologists have excavated a 2,400-year-old pit containing horses and chariots beside a tomb possibly belonging to a lord. The No. 3 Horse and Chariot Pit is one of a cluster of tombs belonging to noble families of the Zheng State, a vassal state during the Spring and Autumn (770-476 B.C) and Warring States periods (475-221 B.C), near the city of Xinzheng. Since February, four chariots and 90 horse skeletons have been unearthed from the pit. [Photo/Xinhua]
