This is a world where women hold power over men. Women and men are not far apart in physical or intellectual ability, but women live longer and possess the unique ability to bear children.
Da Zhou is a nation built on maternal bloodlines. In Da Zhou, a woman can have multiple husbands, and people know only their mother, not their father.
Women have surnames, but men do not. A man can only receive a surname from his wife after marrying her.
Men can only guess whether a child is biologically theirs based on when their wife became pregnant and what the child looks like.
