Describe the difference in the proportion of men and women in a group or phenomenon. "Three men and seven women" is a common saying, which is used to describe the different proportion of men and women in a certain group or phenomenon. It means that in this group or phenomenon, men account for 30% and women account for 70%. This proverb originally comes from the countryside, because in rural families, women will do more housework and men will do more farm work. So "three men and seven women" can also be used to describe the difference in the division of labor between men and women in some families.
