As the initial stage of the national education system, preschool education undertakes the task of laying a solid foundation for children's healthy growth, subsequent learning, and lifelong development; As a social public welfare undertaking, it plays a crucial role in ensuring and improving people's livelihoods, promoting family happiness, and promoting social harmony. The realization of the function of preschool education cannot be separated from the hard work of preschool education teachers. Kindergarten teachers, like teachers in other stages of education, are professionals who fulfill their educational and teaching responsibilities, responsible for teaching and educating people, cultivating builders and successors of the socialist cause, and improving the quality of the nation. At the same time, due to the age characteristics of the educational objects, the work of kindergarten teachers has certain specificity. Numerous research results and extensive life practices have proven that early childhood is the period of rapid development and the strongest plasticity in a person's life. During this period, their bodies develop rapidly, their movements become more flexible, their minds begin to sprout, and their personality traits gradually manifest; At the same time, early childhood is a relatively young, fragile, and vulnerable period in a person's life. Lack of care, safety issues, high expectations and demands beyond the possibility of development, and so on, can all have adverse effects on the physical and mental health of young children. The basic characteristics of children's physical and mental development determine the multifaceted, complex, and special nature of kindergarten teachers' work, as well as the high requirements for professional literacy. But in my opinion, these particularities are sometimes not fully understood by society. For example, the physiological development characteristics of young children often lead to a lack of self-care and self-care abilities. Teachers need help and reminders in daily diet, drinking water, rest and sleep, increasing or decreasing clothing, and avoiding danger. Scientifically arranging and taking care of young children's lives, cultivating their ability to be self-sufficient, safe and healthy is the job content and task of kindergarten teachers. Perhaps these 'things that mothers also do' make some people believe that the work of kindergarten teachers is' not highly professional '. But I don't know that kindergarten teachers should not only "love children like mothers", but also "love children like mothers", and establish caring and caring behavior on the basis of scientific knowledge such as physiology, psychology, and hygiene. The combination of care and education is precisely an important manifestation of the professionalism of kindergarten teachers. For example, the specific visual characteristics of young children's cognitive development make their learning mainly not through words, concepts, and abstract symbols, but through "direct perception, practical operation, and direct experience". They do not use textbooks as learning materials, but view nature and society as "living textbooks"; Their learning venues are often not "classrooms", but scenes of daily life, games, and play. Kindergarten teachers seem to "just take their children to play", but little do they know how to make them play at a high level, how to discover their existing experiences, personality traits, and development needs during play, how to use the situation to guide intellectual enlightenment, and naturally integrate social culture and educational goals into children's self-developed games and various favorite activities. Teaching through entertainment and personalized teaching is a test of teachers' professional knowledge, ability, and educational wisdom. The basic characteristic of 'profession' is' irreplaceability ', and the profession of kindergarten teachers fully possesses such characteristics. The growth of young children not only requires scientific guidance, but also emotional companionship. Therefore, no matter how science and technology develop
