In recent years, women research has been a fast growing study area. In response of the trend of referring to women as "the second sex," researchers have started to discuss traditional women's life in the light of a non-traditional sense. Despite this effort, researchers still find themselves focusing on old issues. Marriage, unavoidably, is still the major topic of the discussion of traditional Chinese women's life. However, aspects of traditional Chinese women's life in a marriage, not the marriage itself, are rarely discussed. In addition to topics such as married women's status in the new family, issues of inheritance, and individual's free wills, topics such as married women's daily life and interpersonal relationships are especially in need of more researches.
