Infidelity is not a male privilege. Even in ancient times when women were bound by the "three obediences and four virtues", some women, even if they were empresses, concubines, or princesses, were dissatisfied with their marital status and sought "extramarital affairs". The term "infidelity" referred to in this article means having an affair with other men while the husband is still alive, and does not include cases like Zhao Ji, the biological mother of Qin Shi Huang, who was widowed.
