Prince Zhuangxiang of Qin, so he was given the surname Zhao like his eldest brother at that time, and later changed it back
Ying Zheng was born in Zhao State, and his father had not yet been able to return to the country at that time. Ying Zheng has an eldest brother, Cheng Jie, who is still serving as a hostage in the State of Zhao. The surname Zhao personally believes that the "policy" in "Ying Zheng" only means the original meaning: upright and upright
It does not mean gaining any power
PS. King Zhuang Xiang was Qin's hostage to Zhao. It is also possible that his father was about to gain power, so he took it and gave birth to the first emperor. Since King Zhao of Qin was born in Handan in the first month of the 48th year of the Qin Dynasty, it stands to reason that the one who gained power should be his eldest brother, not him. For politics: "Ying" is just a surname, but at this time Lu Buwei had already paved the way for his father to return to the country. When he was born, he was in Zhao State and met Lu Buwei Ji, but it should have nothing to do with Ying Zheng itself. In "The Biography of the Kingdoms of the Eastern Zhou Dynasty", Lu Buwei also believed that Yingzheng's eldest brother was a threat to Yingzheng's accession to the throne
