Chengjiao (prince)


Chengjiao, titled Lord of Chang'an, was Qin Shi Huang's paternal half brother. After Zhao Zheng inherited the title of King of Qin from his father King Zhuangxiang, he 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.

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, 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

In Kingdom, he launched a coup that tried to kill Qin Shi Huang alongside his own faction. He was later overthrown by Lord Changwen, Xin, loyalists and the mountain tribes. He was later pardoned and allowed leadership during Qin Shi Huang's campaigns. He was also appointed leader during a border war, but torn when the city he expected to be defended, rebelled. He was later killed by a rebel commander after being cornered, using him as an excuse to foment distrust to his brother.
He also appeared as an enemy of Qin Shi Huang and the protagonist Xiang Shaolong in Huang Yi's novel and its drama, game and comics adaptations.
