Because exams are generally based on professional topics, we should practice preschool education more.

Education is a unique social activity to cultivate people. Education comes into being with the emergence of human society and develops with the development of society. Since ancient times, the development of education has different historical characteristics. However, preschool education is a discipline gradually formed on the basis of the development of educational practice. Preschool education has its unique research object and distinctive subject characteristics. Its development has gone through embryonic stage, independent form and development stage. Education is all purposeful, planned and organized activities to enhance people's knowledge and skills and influence people's ideology and morality. Preschool education is a subject that studies educational phenomena and problems and reveals educational laws. First of all, we must master the "three basics", that is, basic concepts, basic theories and basic knowledge, and understand relevant new information. Secondly, in the usual study, we should learn more related subjects, such as philosophy, psychology, educational psychology, sociology, educational statistics, political economy, ethics, computer, etc., and pay attention to integrating theory with practice. Finally, we should pay attention to consulting relevant bibliographies and using reference tools, browsing some original educational works and reading relevant magazines and newspapers.
