Люй Бувэй
Using bribes and machinations, Lü Buwei arranged for Yiren to return to Qin and successfully persuaded Lady Huayang to adopt Yiren as her son, thereby making Yiren the heir apparent to Lord Anguo. Lady Huayang renamed Yiren to "Zichu" (子楚; lit. "son of Chu") because she was from the Chu state.
