Lü Buwei
When King Zhuangxiang died in 247 BC, Crown Prince Zheng ascended the throne and Lady Zhao became the Queen Dowager. Sima Qian claimed she continued her affair with Lü Buwei but, facing exposure and persecution, he gave her a man named Lao Ai disguised as a eunuch. The couple produced two illegitimate children. After Lao Ai was killed during an attempted "coup d'état", the queen was imprisoned in her palace and the children were killed.
