A history of human civilization development, in some sense is the evolutionary history of relations between the sexes. Labor is the motive force of human civilization development, which not only created man but also transform the people. What makes a distinction between people and animals is work, and that make a distinction between person and person is the social division of labor of labor. Social division of labor gives each person a different social status, allocates a different social space, be under different social responsibility and plays a different social role. As part of the people, without exception, women were influenced by social division of labor inevitably.

Due to the strong physique, men went fishing and hunting, be against the beast with great blindness and chance. And for the reason that the tools were extremely crude it lead to a bad situation that the harvest was very limited; Due to weaker physique and flexible fingers, women did some word like gathering fruit and making clothing, which were stable and had a relatively good harvest and then became the main source of clan members life. Women found the rule of the growth of plants in long-term engaged in the acquisition of labor, and began regular collection and to plant in small area, thus invented the primitive agriculture, which enabled them become the main agricultural labor. Survival needs led to women's important status. In old China, the status of women caring inside household, men dominating outside of household had never changed. For women, they bare the high pressure under working environment and the responsible for breeding babies. ”In fact, 90 per cent of workers sent home were women with small children. For the women involved, the loss of income caused serious material difficulties”(Tamara Jacka,1990,p3).(责任编辑：anne)
