During ancient China, concubinage was a common practice, particularly among wealthy and powerful families. Women who were chosen to be concubines were usually from poor or lower-class families and were expected to serve the man and his legitimate wife. While the status of concubines was considered inferior, they played an essential role in the Chinese social hierarchy, providing heirs and additional labor to their masters. As a result, many practices and customs were developed over time, and certain things were considered normal for Chinese concubines.
