1. Educate children aged 0 to 3. The rise of early education is closely related to the research progress of human nervous system, especially cranial nerve development in the medical field. In recent years, research in neurology and brain science has found that the development of cranial nerves closely related to human intelligence is not only in the embryonic stage, but also lasts for three years after birth. The proliferation of glial cells in the brain can last until the age of 2, and the neurons in the cerebral cortex do not stop differentiating until the age of 3. It can be seen that the education of 0-3 years old can change people's brain structure, which provides a physiological and material basis for the feasibility of early education.

2. Psychologists have found that the critical period of human intelligence development is 0-3 years old. American psychologists believe that 50% of human intelligence is formed before the age of 4, another 30% is formed at the age of 8, and the remaining 20% is completed at the age of 17. It can be seen that early education from the age of 0 is of great significance to people's intellectual development. If heredity provides the basis of human intelligence, then early educational experience determines the actual structure of the brain.
