There is a difference between early education and preschool education. Now, in order to make money, some early education institutions exaggerate the significance of early education and educate children as adults, so that children lose their happy childhood. The traditional preschool education mode is to give children more free and open play space, promote the balanced development of children's brains and lay a good foundation for children. The harm of adult early education to children is irreversible, and it is clear to understand the brain development process of babies.
