《墨子·06章 辞过》
现在的国君养侍妾，大国拘禁女子数千，小国数百，所以天下男子大多没有妻子，女子多遭拘禁而没有丈夫。男女婚姻失时，所以百姓减少。
当今之君，其蓄私也，大国拘女累千，小国累百，是以天下之男多寡无妻，女多拘无夫，男女失时，故民少。
The kings of the present day keep concubines, and in large countries there are thousands of unmarried women in the palace, and in small countries hundreds, so most of the men in the world have no wives, and most of the women are unmarried and have no husbands. Since men and women are unable to marry when they should, the number of people in the world decreases.
