走出家门到大城市赚钱养家，是中国亿万农民工的选择。由于各种因素，很多外出农民工无法携带家眷，夫妻二人长期分居。为了寻求心理与生理上的慰藉，越来越多的已婚打工男女组建起“临时家庭”，成为游走在伦理和法律边缘的“临时夫妻”。

As breadwinners of their families, hundreds of millions of farmer-turned migrant workers come to town out of choice. For various reasons, many of them have to leave their spouses and children behind bringing a long separation between husbands and wives. In order to seek solace both physically and psychologically, more and more married male and female workers have temporarily founded a second family exploiting their advantages with the permission of law and ethics.
