The concept of "Sansheng Education" is the concept of school moral education, which includes "life education", "life education" and "survival education". "Life education" makes every teacher and student "know life, respect life, cherish life and care for themselves and their families"; "Life education" advocates "cherishing life, understanding common sense of life, mastering life skills, forming good living habits, caring for others and the collective, and setting correct life goals"; "Survival education" emphasizes "learning survival knowledge, protecting and cherishing the ecological environment, caring for society and nature, enhancing the will to survive and improving the adaptability and creativity of survival". Take "Sansheng Education" as the starting point of school moral education, take "Sansheng Education" as the soul of school moral education, cover school moral education in "Sansheng Education", coordinate student education, teacher's morality education, family education, school education and social education in the concept of "Sansheng Education", carry out moral education activities in a targeted and effective way, and build a brand of school moral education. Life education is the education of life culture and life wisdom. The research of life education involves the value, core idea, family education, contents and methods of school life education and guarantee mechanism, especially the optimization of life education environment for teenagers. School life education refers to imparting knowledge of life development to primary and secondary school students and faculty, so that they can have a certain understanding of themselves, cherish and respect others' lives, cultivate students' love for society and others, especially the disabled, and make primary and secondary school students' personalities develop in an all-round way, so that faculty and staff can cherish life more and make life more meaningful. Tao Xingzhi believes that "life is education", and he believes that life education has six characteristics: life, action, mass, progress, world and historical connection. School life education starts with improving teachers' quality of life, and starts with teachers' and students' daily life, such as walking, eating, talking, communicating and being grateful, so as to cultivate students' living ability, cherish life, cherish family and collective, and let students and teachers grow together. Ecological education is an ideological system that advocates the harmonious coexistence between man and nature, and it is the sum of thoughts, concepts and consciousness reflected by people's optimal solution to the relationship between man and nature according to the needs and possibilities of ecological relationship. Ecological education in schools must make teachers and students pay attention to and care for nature, publicize advanced ecological knowledge and the significance of ecological protection, start from trivial matters, cherish ecology, care about society and nature, take environmental construction, environmental protection and green civilization construction as important components of ecological education, and truly establish teachers and students' awareness of environmental protection and sustainable development. "Sansheng Education" is a holistic and systematic moral education in schools. "Sansheng Education" truly embodies the school-running philosophy of "people-oriented, morality first, emphasis on foundation, strong innovation, and sustainable middle school students". In recent years, in the field of moral education research, many researchers have deeply realized the serious consequences caused by too high and empty moral education goals, too rational and abstract moral education content, too single moral education approach and even violation of the laws of students' moral and psychological development. Therefore, moral education needs to be close to life, and strengthening the practice of emotional and moral subjects has gradually become a research trend. The introduction of life education, life education and ecological education into moral education has cut the drawbacks of the traditional moral education preaching model and gradually become the frontier topic of educational science research in China. The research and practice of this kind of topic, to a certain extent, has changed the single rigid moral education mode and improved the actual effect of moral education. At the same time, the research and implementation process has improved the rational understanding and practical level of grass-roots teachers' moral education for middle school students, provided some successful cases for moral education theory research, and optimized the school moral education mechanism that embodies the concepts of life, life and ecology. However, the related moral education research pays more attention to the general theoretical summary and experience summary, and the research on how to promote the development of students' moral literacy and moral ability through life education, life education and ecological education in moral education, as well as its popularization and application in a wider range, is still in the exploratory stage, and there is no practical research. The research of "Sansheng Education" aims to reflect on the effectiveness of life education, life education and ecological education at present, jump out of the single concept of life education, life education and ecological education, make necessary integration of the three, and build a new thinking platform for the renewal of school moral education concepts. Strive to build a moral education concept that integrates life, life and ecological education, and formulate a moral education concept that conforms to the physical and mental development of middle school students.
