The popular definition of family education in China is three kinds of education, namely, the way of life, the way of being a man and the way of learning. Short for "3M". Namely:
The Way to Make a Living is centered on life and health, and consists of three aspects: physical health (health), mental health (happiness) and safe adaptation (safety).
"The way to be a man" takes the value of life as the core and consists of three aspects: life role (foundation), personality life (ambition) and social accomplishment (communication).
The "Learning Way" takes the wisdom of life as the core, and consists of three aspects: learning quality (learning), comprehensive literacy (elements) and independent expertise (specialties).
The 3M family education atlas is designed according to the three life development education theories. The proposal of "Three Educational Theories" provides a basic basis for minor education, especially family education, and enables parents to carry out relevant educational activities for their children scientifically, orderly and clearly according to the contents and standards of "Three Educational Theories". The three educational theories provide a good foundation for solving the current situation that family education lacks operability standards, and also provide a comprehensive and systematic academic foundation and framework for family education theories. Zhao Yulin, an expert in youth education in China, put forward three life development education theories in 2008. At the same time, he pointed out that family education is an activity that comprehensively promotes family construction and development in a broad sense, and in a narrow sense, it refers to all activities that promote the growth of the quality of life of-1~ 18 years old, that is, the appreciation of individual life.
