1. Preschool education is the most important and critical period for people's physical development, intelligence and experience development. Bloom, an American psychologist, put forward a famous hypothesis in the book "Stability and Change of Human Characteristics": If a person's intellectual development level is l00 at the age of 17, it will be 50% by the age of 4. At the age of 8, it reached 80%, and the remaining 20% was obtained from the 9 years of 8- 17. Therefore, preschool education is the most important and crucial period for the development of human body, intelligence and experience.

2. Pre-school education is the biggest and fastest period of life change, and it is also the most prone to development and frustration. During this period, children can only cry, crawl, walk and run. Not only has their body changed greatly, but all their cognition, experience and ability have gone through a process from scratch. Therefore, objectively, the pre-school education stage is the biggest and fastest changing period in life. If we don't follow the characteristics and laws of children's physical and mental development, and don't conform to the natural development of children in this period, we will adopt a unified educational method to bind children's hands and feet, imprison their thinking and form a mechanical mindset, even for spaceships painted by children, which will inevitably hinder the development of children's various potentials, miss the sensitive period of children and delay the growth of genius. Preschool education is the most important stage of training and equipping the mind in life. It not only prepares for primary school, but also lays an important foundation for people's life, which directly affects the height, width and firmness of the building in people's life. Because it involves the exploration of children's various potentials, the cultivation of various will qualities, the acquisition of various necessary life experiences and the cultivation of good habits, we should not only pay attention to the display of personality, but also pay attention to children's all-round development. Preschool teachers should not only have the wisdom of educators to guide and help children develop various abilities, but also have the accurate judgment of experts and appropriate educational methods to stimulate children's various potentials and grasp the sensitive period of different children. Therefore, objectively, higher requirements are put forward for the training of preschool education professionals.
