Люй Бувэй
Yiren was born to Lord Anguo, the second son and heir apparent of King Zhaoxiang, and Lord Anguo's concubine Lady Xia. He was chosen to serve as a political hostage in the Kingdom of Zhao. In Handan (the capital of Zhao) he met a merchant, Lü Buwei, who saw Yiren as extraordinary and detected in him the potential to become the king of Qin in the future. Lü Buwei treated Yiren well and presented his concubine Lady Zhao to Yiren. Lady Zhao later bore Yiren a son, Ying Zheng.
