About Chengjiao

Chengjiao, titled Lord of Chang'an, was the son of King Zhuangxiang of Qin and the paternal younger half-brother of Qin Shi Huang. After Ying Zheng inherited the title of King of Qin from his father King Zhuangxiang, Chengjiao rebelled at Tunliu and surrendered to the State of Zhao. King Daoxiang of Zhao granted him the territory of Rao. In 239 BC, Qin forces occupied Rao and he was killed.
