《资治通鉴·秦纪·秦纪一》
赵迁的母亲原是妓女，深得悼襄王的宠幸。为此，悼襄王废掉了正妻所生的长子赵嘉，将赵迁立为太子。
其母，倡也，嬖于悼襄王，悼襄王废嫡子嘉而立之。
Zhao Qian's mother was a prostitute who enjoyed great favour from King Xiang of Dai. To this end, King Xiang of Dai expelled his eldest son, Zhao Jia, who was born to his wife, and appointed Zhao Qian as crown prince.
