Traditional conservation work includes physical examination, daily routine, diet and nutrition, exercise and safety, environmental sanitation, disease prevention and so on.
With the development of society, the concept of conservation has expanded from the traditional "protecting physical development" to "promoting children's personality development and improving social adaptability", and from "safety protection and hygiene" to "implementing physical, psychological and social health care in the process of education". On the basis of this new concept of saving, saving should not only reflect the all-round development of education, but also reflect the actual needs of society and talent development in the next century. We should not only do a good job in traditional protection, but also attach importance to the interactive process of "protection" and "education" and truly combine protection and education.
