Children in early education group received “The infant physical and mental exercise” designed by us from embryo to 1 year old, and their parents carried on the training by referring to parental manual for infants from 1 year old to 3 years old. All children were evaluated by Gesell developmental scales at 1 year and 3 years old，and by Wechsler Intelligence Scale for Children-Revised at 7 years old.Results The DQs of children in early education group were statistically higher than those of children in control group, nevertheless the IQs between the two groups showed no statistical difference.Conclusion Early education can promote intellectual development in infant, but the long term effect on intelligence of children was not found.
