What preschool education should teach after all is a problem that we have to consider in order to run preschool education well. According to the law of preschool children’s physical and mental development and the needs of today’s social development, preschool education should promote preschool children’s physical and mental and social development, cultivate preschool children’s positive competence, and lay a solid foundation for preschool children’s lifelong development. It should cultivate the core competences that people should have today to lay a positive “keynote” for preschool children’s lifelong development, rather than teach preschool children knowledge and skills as the current preschool education of primary schoolization. Therefore, on the current vision of cultivating craftsman’s psyches, preschool education should focus on cultivating preschool children's positive psychological and behavioral qualities, such as good behavior habits, determination, sense of responsibility, creativity, curiosity, indomitable spirit, enterprising spirit and EQ.
