In 2056 AD, due to a severe cosmic radiation, the ratio of male and female children on the earth was severely dysfunctional, and the ratio of male and female before radiation quickly changed from 1:105 to 1:20. That is, every time a boy is born, 20 girls are born, and this ratio is still rising, and the scientific community is helpless! This has caused many social problems, first of all, employment problems. Due to limited jobs suitable for women, a large number of women face unemployment and marriage problems. Due to the imbalance in the ratio of men and women, monogamy is being implemented.On the basis of this, a large number of unmarried women were produced, which led to social instability factors. In response, governments have taken a lot of measures, such as abolishing monogamy, but few men are willing to marry 20 wives. Although governments have taken a lot of measures, the employment and marriage issues of women are still the biggest problem worldwide. Women's organizations are constantly pressuring the government. No matter what methods the government uses, as long as it can improve the employment and marriage rates of women, it can win a large number of votes. Under this situation, governments have taken a lot of previously incredible methods.
