Although the scholars didn't define family and household normatively, they revealed the basic characteristics of family and household around the 1930s. However, the definition of home and the scope of its members were less discussed. In contemporary research of family, family, household and home are often mixed together. The author puts forward the idea of giving consideration to family, household and home. It is necessary to pay attention to family and household based on the living unit and dwelling unit on the one hand, and to the home organization based on the male blood relationship and the contemporary lineal home organization formed by the lineal intergenerational relationship on the other hand, so as to promote the analysis level of historical and the contemporary family and kinship.
