During the
Spring and Autumn period of Chinese history (770-476 BCE), Yunmeng County formed part of the
Zhou dynasty vassal
State of Yun, later annexed by the
State of Chu whose kings used the area as a hunting ground. After Chu's defeat at the hands of the
State of Qin in 223 BCE, Yunmeng became part of Qin territory. Legend suggests that China's first emperor
Qin Shi Huang visited the county in 219 BCE. Yunmeng was the location of the
Jiangxia Commandery of the
Han dynasty and the cradle of the Chinese
Huang Clan. ==Administrative divisions==
