Legal analysis: preschool classes have three different periods: one year, six months and two to three months. Education cannot be completely market-oriented. On the one hand, the government should vigorously develop public kindergartens and make rational distribution; On the other hand, we should actively standardize the development of private kindergartens.

Legal basis: Guiding Opinions of the Ministry of Education on Vigorously Promoting the Scientific Connection between Kindergartens and Primary Schools III. Main measures (1) Kindergartens should make good preparations for admission. Kindergartens should implement the "Guide to Learning and Development for Children Aged 3-6" and the "Guidelines for Kindergarten Education" to promote the comprehensive and harmonious development of children's body and mind, prepare for the basic quality of admission, and lay a solid foundation for lifelong development. It is necessary to further guide teachers to establish the concept of scientific connection, and large classes should help children prepare for life, society and study in the next semester, and establish positive expectations and yearning for primary school life. It is necessary to prevent and correct the wrong practice of simply moving the environment, educational content and educational methods of primary schools to kindergartens.

(2) Implementing primary school entrance education. Primary schools should strengthen the awareness of connection, take school adaptation education as an important task to deepen the teaching reform of compulsory education courses, and bring it into the first-grade education and teaching plan to realize the connection between education and teaching methods and kindergarten education. The state revised the curriculum standard of compulsory education, adjusted the curriculum arrangement of the first grade, rationally arranged the content gradient, and slowed down the teaching progress. Primary schools set the first semester of senior one as the school adaptation period, focusing on the implementation of school adaptation education. Mainly use local courses, school courses and comprehensive practical activities to organize school adaptation activities to ensure the class schedule. To reform the teaching methods of first-grade education, the national curriculum mainly adopts the methods of gamification, life and integration to strengthen children's inquiry and experiential learning. It is necessary to effectively change the phenomenon of neglecting children's physical and mental characteristics and acceptance, and resolutely correct the wrong practices of exceeding the standard teaching and blindly catching up with the progress.
