In a great country with a population of one billion, family planning is increasingly becoming a serious issue for our own survival, and contraception has become a necessary means for us to "save ourselves" in reproductive activities. However, setting aside the idea of "the more children, the more happiness" held by the majority of Chinese people, the number of people who come to this world due to contraceptive failure is also a huge figure. Here, we still use the method of on-site interviews to truly record the history of contraception among Chinese women in the past hundred years. Although it cannot be generalized from a single case, it can still give us a glimpse. When we find it funny for their ignorance and absurdity, and are shocked by their suffering and bitterness, we will realize how urgent it is to popularize sex education!
