Higher education refers to education that does not meet the age group.

Complete explanation:

The preschool period of 0-6 years old is a critical period for children's physical and mental development. Early education is not simply to improve IQ, but to develop children's potential in educational activities. It is an education that focuses on the learning process rather than simply pursuing skill training and knowledge mastery, which makes it easier for children to absorb knowledge and develop their specialties in their later study and life. The advanced education is to advance children's education time greatly, for example, let children master the knowledge of children aged 3-6 before the age of 3, and learn middle school courses in primary schools and college courses in middle schools.

Danger:

Advanced education requires children to learn the knowledge of older children in order to achieve a state that looks "smarter than other children". The purpose of this kind of education is embodied in the popular "young college students" in recent years, and the advanced education contains many psychological factors of parents' utility.
