Modern motherhood and fatherhood in China,which connects the society and individuals,material production and human reproduction,labor market and family life,were born in the modernization era since the end of Qing Dynasty. Based on the mainstream motherhood discourse, the labor laws of the Nationalist Party and the Chinese Communist Party during 1929-1933 constructed the standards for the modern working women’s motherhood,i. e.,the main caregiver and the second breadwinner.These labor laws also vaguely outlined the modern fatherhood,which was in opposition to and complementation of the motherhood, as the main breadwinner and absent caregiver according to the gender logic of these laws and their preliminary exploration of the modern fatherhood.
