Overview

Chengjiao (; 256–239 BC), 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 (; modern Raoyang County, Hebei). In 239 BC, Qin forces occupied Rao and he was killed. Potential betrayal There are disputes on whether he actually betrayed Qin for such a small land as Rao, as indicated that he did not suffer the punishment of dismemberment as Pu Gu (蒲鶮), a captain of sorts of the traitors in Tunliu. Family Some historians, including Li Kaiyuan and Ma Feibai, hypothesize that Ziying, the last king of Qin, may be his son. In popular culture
