Establishing and improving the inclusive preschool education public service system and improving people’s satisfaction of preschool is an important task stipulated in the Preschool Education Law. It is not only a key measure to ensure children’s equal right to development, but also a major livelihood project that consolidates the foundation of national education and concerns the well-being of thousands of families. Looking back on the development process, China has achieved remarkable historic achievements in preschool education by successively implementing three phases of the Three-Year Action Plan for preschool education. The prominent social problem of “difficulty in getting into kindergartens”, which has long plagued society, has been effectively alleviated, enabling millions of children to enjoy basic preschool education services. However, behind these achievements, there are still problems such as unbalanced allocation of educational resources and prominent contradictions between supply and demand; weak quality assurance system and concerns about the implementation of children’s rights and interests; and shortage and insufficient coverage of inclusive nursery services. The promulgation of the Preschool Education Law marks that the construction of China’s inclusive preschool education public service system has officially entered the legalization stage. It clarifies the direction of development and construction from the legal perspective, adhering to the principles of public welfare and inclusiveness, standards of safety and quality, mechanisms led by the government, and layouts of balanced coverage. In the future, based on the Preschool Education Law, our government needs to promote the continuous development of its preschool education public service system towards a higher level of inclusiveness, popularization, safety, reliability and high quality through paths such as optimizing resource allocation and supply structure; strengthening quality supervision and protection of rights and interests; enhancing the construction of teaching staff; and promoting transformation to realize the integration of nursery and kindergarten education. Finally, it will achieve the beautiful goal of “providing good care and quality education for young children” and lay a solid foundation of talents for the great cause of national rejuvenation.
