China has had 1 female rulers (emperors).
Women in ancient and imperial China were prohibited from participating in a variety of social activities by social norms that required them to stay indoors while males handled outside business.
Male and female history were divided by the rigid sex division, which is seen in the rule that "men plow, women weave," as early as the Zhou dynasty. The Rites of Zhou even required that women be taught particularly in "women's rites."
