All-round development of children: Preschool education is an important stage of children's growth and development. Through preschool education, children can be helped to develop in cognitive, emotional, social and language aspects, and lay a good foundation for their future study and life.

Promote educational equity: Incorporating preschool education into compulsory education can promote educational equity and ensure that every child can enjoy the opportunity to receive high-quality preschool education and obtain equal educational resources regardless of family background and geographical location.

Improve the quality of education: Preschool education is an important part of the education system, and bringing it into the compulsory education stage can improve the quality of the whole education system. By unifying teaching standards, teacher training and textbook compilation, the level and quality of preschool education will be improved to better meet the needs of children's growth and development.

Promoting economic development: Vigorously developing pre-school education will help to cultivate more outstanding talents, improve national quality and innovation ability, and thus promote the sustainable development of social economy. Good pre-school education can also reduce the cost of subsequent education investment, such as reducing the demand for special education and reducing the cost of social security.

To sum up, it is necessary to bring preschool education into compulsory education, which can promote children's all-round development, improve education equity, improve education quality and promote economic development.
