1, premature reading and writing activities will affect the normal development of children. Although these intellectual learning processes can be designed to be very interesting, abstract intellectual learning itself is a highly complex activity, which will lead to children's psychological tension, consume a lot of internal energy and directly affect their normal physical and mental development.

Normal children often get sick, such as catching a cold, which is a process for children to build their own immunity, but children will recover quickly and become stronger after recovery. But in contrast, children who develop their intelligence too early are more likely to get sick, have worse physical fitness and are more vulnerable psychologically, because their inner energy is consumed in large quantities.

2. Premature intellectual learning will affect the normal development of children's other abilities. Children's abilities need to develop in parallel. Because children's energy is limited, if one aspect's ability is overemphasized, other aspects' ability will not be well developed. Premature intellectual learning will affect and damage the development of children's other abilities, such as music ability, sports coordination ability, interpersonal skills and so on.

3, the actual feeling of lack of experience will bring emotional problems. Before abstract learning, children need to fully contact with the real world and develop the coordination of their sensory organs, brain and motor system through a lot of play and exercise. Abstract learning in advance may make children feel inexperienced, which will destroy love, interest, curiosity and sympathy in human nature, which may lead to: indifference, loneliness, indifference, dullness, lack of compassion and insensitivity.
