In some European countries, such as Sweden, Finland and the Netherlands, preschool education pays attention to children's autonomy, playfulness and social development, and emphasizes equal interaction and individualized attention between teachers and children to avoid the separation of education and protection as much as possible. However, in some Asian countries, such as China, South Korea and Japan, preschool education pays more attention to examination results, knowledge and skills, discipline and norms. Moreover, the education mode is relatively rigid, which easily leads to the disconnection between education and protection. It is not unique to a certain country, but exists all over the world. Different countries and regions have great differences in the concept, mode and practical methods of preschool education, which leads to the separation of education and education to varying degrees.
