Early education is definitely necessary, but not every child who participates in the early education training class will be smarter or know more than those who do not. Early education is necessary, but it doesn't have to be in an early education center or participate in paid early education training. I think parents can educate their children according to their characteristics. Many methods and theories of early education can be taught by themselves through the internet or books. This not only educates children, but also increases their knowledge.
