Early childhood education, that is, early education, is an education that focuses on the targeted interest development of children aged 0-6. According to the characteristics of children's physical and mental development and the development characteristics of sensitive period, targeted guidance and training are carried out to lay a good foundation for the cultivation of children's multiple intelligences and healthy personality.

In a broad sense, it refers to education from birth to preschool, and in a narrow sense, it mainly refers to early learning in the above stages. In some countries, early learning of reading, writing and calculation has been explored and experimented in early childhood education and early formal education. But others think that early education should focus on developing intelligence.

Others believe that early education should be extended to prenatal education before the mother is born. Family education has a great influence on early education. Among them, the theory of "three-dimensional balanced development of physical quality, intelligence and psychological ability" is the most scientific. Based on 50 thousand children's growth benchmark data, nine children's growth goals are extracted: security, willpower, sense of purpose, attention, memory, thinking ability, balance, strength and speed.
