1. Early reading: Although reading is beneficial to children's language and cognitive development, overemphasizing early reading and even exposing infants to books that are too advanced may cause stress and burden, which will have a negative impact on children's reading interests and habits.
2. Early Mathematics: Although mathematics is an important subject, overemphasizing early mathematics and even exposing infants to too advanced mathematical concepts may cause pressure and burden, which will have a negative impact on children's interest in mathematics and learning.
3. Early English: Although English is an important language, putting too much emphasis on early English, even putting children in an English language environment that is too advanced, may cause pressure and burden, which will have a negative impact on children's English learning and interest.
4. Large-class training: Too much emphasis on large-class training and even letting children participate in too many training courses and extracurricular activities may cause physical and mental fatigue and anxiety, which will have a negative impact on children's physical and mental health and learning.
5. Too much emphasis on grades: too much emphasis on academic performance and competition, and even letting children accept too many exams and evaluations may cause stress and anxiety, which will have a negative impact on children's physical and mental health and learning.
In short, preschool education should follow children's development laws and interest characteristics, not be overly demanding and wasteful, and should focus on cultivating children's interest and curiosity, so that they can naturally grow and learn in a free and happy environment.
