Family planning is the basic national policy of our country. However, the implementation of family planning has always been a thorny issue. China's family planning policy is related to many systems, such as medical system, marriage system and population migration system. How to educate people to establish a correct concept of marriage and childbearing by propagating the national policy of family planning is a problem that must be solved in the process of building a society ruled by law in China. The imbalance between urban and rural economic development and the imbalance between eastern and western development will hinder the solution of this problem. This paper will explain the positive role of family planning in establishing a correct concept of marriage and childbirth by analyzing our understanding of family planning and the scientific nature of the basic national policy of family planning. Keywords: family planning; Publicity and education; Concept of marriage and childbearing; As a basic national policy of our country, the family planning system has played a very positive role in population development and control since its implementation. For a super populous country like China, both the population base and the number of families are very large. Considering the management, development and improvement of population quality, China's Marriage Law clearly stipulates the legal age of marriage for both men and women, but it does not legally restrict the social phenomenon of cohabitation. As a result, various social and demographic phenomena emerge one after another. 1 the impact of the implementation of China's family planning policy on the population structure 1. 1 China's population structure From the perspective of China's current population structure, from the perspective of gender, there are more men than women on the whole; Geographically, with the Aihui-Tengchong population boundary as the boundary, the population base and density in the southeast are greater than those in the northwest; Taking the age as the standard, China is aging, and the national population is aging rapidly, while the number of minors is too large, forming an unfavorable development pattern with two big heads and a small middle. 1.2 Achievements of Family Planning in China Through the unremitting implementation of the family planning policy, which was established as a national policy in 1978, China's family planning work has made great achievements, but due to the one-sidedness of the system, many far-reaching problems have also appeared in the implementation process. One of the most far-reaching points is that the one-child policy is implemented everywhere, and different policies are implemented without analyzing the social differences between regions. After this round of population aging, the population of the whole country will face a sharp decline, which will seriously affect the future of the country. 2. The influence of family planning on marriage 2. 1 Based on the one-sided summary of family planning in the Marriage Law, the increasingly prominent population structure contradiction in China is the biggest constraint factor for social stability and harmonious development. After 2005, the proportion of marriageable men is much higher than that of women, which shows that a large number of men will not find their own marriage partners. The enrollment expansion in colleges and universities further intensifies the competition in China's job market, which leads to the reduction of employment opportunities for low-income people, and the marriage result between low-income people and low-quality people is even more difficult. The bad hidden danger of this situation to society will exist for a long time to come. It is reported that in 2020, there will be more than 30 million men aged between 20 and 45 in China who cannot match their marriage partners. One-sided population imbalance is a major failure of family planning publicity and education. In the vast rural areas of China, if the first child is a girl, you can have a second child, and if you are still a girl, you can have a third child. This policy caters to the psychology of China people: the purpose is to have a boy, and if the first child is a boy, then the policy will not allow the second child. 2.2 Rationality explanation of family planning education based on China's basic national conditions: advocating late marriage, late childbearing and fewer children. Among them, eugenics does not mean having boys, but improving the survival rate of newborns and the quality of the population. However, many people in China are still poisoned by the traditional feudal concept, and think that it is better to have a son than a daughter. The rational explanation of family planning educates marriageable men and women, and decides that children born after marriage should be treated equally regardless of gender. 2.3 The imbalance between men and women caused by family planning "squeezes" marriage. The most obvious social phenomenon is cohabitation. The social relationship of cohabitation is not guaranteed by law, which leads many women to resort to abortion and abortion to solve the fertility problem after contraceptive failure. The imbalance between men and women makes it more difficult for men to find a partner than women. Coupled with the infiltration of western culture in modern society, the understanding of marriage and childbirth after 1980s and 1990s is very different from that of the previous generation. Many people choose not to marry, and many people become leftover women and men. This has resulted in the polarization of China's population structure. 3. Educate people to establish a correct concept of marriage and childbearing through the propaganda of family planning policy. 3. 1 the influence of family planning on people's choice of marriage and childbearing time. China's aging population and the huge number of minors have brought great pressure to the main workers in the family. In some families, both men and women have to bear the responsibility of raising the elderly and children. According to the marriage age of men, some men are still in college at the age of 22, while in rural areas, 22-year-old young men have become fathers. Unwilling to get married and have children or having no conditions to get married and have children are all more or less affected by the family planning policy. On the one hand, marriage means having children, and having children means bearing greater economic pressure. Through the propaganda of family planning policy, marriageable men and women have a correct world outlook on marriage and childbearing, and know the significance of forming a family and giving birth to the next generation. 3.2 Bottleneck of family planning publicity and education The influence of family planning publicity and education not only comes from the western free and open culture, but also is influenced by the actual situation in China. Some couples simply try marriage, flash marriage and flash divorce, which is extremely unfavorable for forming a stable marriage and family. In the context of fierce social competition, life becomes more difficult, and childbirth will bring greater pressure to families. Many open-minded and avant-garde couples even choose not to have children. This is in stark contrast to the phenomenon that poor and backward areas still drag out an ignoble existence. The long-term development of this phenomenon will lead to the decline of the overall quality of the population. 3.3 The role of family planning publicity and education in the management of marriage, family and population. The difficult process of the new round of population census in China shows that it is more and more difficult to manage and regulate the population. Frequent population movement and low fertility level in family planning are severe challenges to stable marriage and family. According to the survey data, more than 75% of adult men and women hold an approval attitude towards cohabitation. In view of this situation, the state must register more married families and unmarried families in the floating population gathering places in economically developed areas, increase the protection of legally married families, and at the same time introduce laws to manage unmarried cohabiting population as soon as possible to avoid the decline of reproductive quality of women of childbearing age. Propagandize family planning and establish a correct concept of marriage and childbearing. 4. 1 through the basic work of family planning, go deep into families, especially newly formed families, and strengthen the management of marriage and family. Register and manage the married population, understand the basic population of marriage and family at the same time, and reduce the social divorce rate by limiting the conditions for marriage and divorce of family population. To stipulate the mutual obligations between family members and safeguard their rights. 4.2 Distribute to families by publishing pamphlets; Strengthen marriage and family visits, understand the attitude of marriage and family to marriage and childbirth at multiple levels and through multiple channels, and explain the significance of birth concept to family and country to marriage and family members. Efforts should be made to grasp the views and opinions of married family members and men and women who are about to get married on marriage and childbearing through various understandings, sum up and formulate relevant policies, carry out differentiated publicity in different regions, and realistically popularize the basic contents of family planning. 4.3 Strengthen legislation and implement the knowledge of healthy childbearing.
