I don't know whether early education can improve children's IQ, but I think that without early education, children's IQ will definitely be lower than their peers. I have an example around me. My husband's friend's son's parents don't know early education. During the day, the old man takes care of the children and hardly talks to them. They just eat and drink Lazar, and their parents won't teach their children to talk when they get home from work. So until they were three years old, the children couldn't talk. If he wants to eat, he will only make a strange call of "vomiting". He only calls his parents, not even his uncles and aunts. Later, I went to school and have been a poor student. The point is that when he was seven or eight years old, when we were eating, half of him didn't understand and couldn't even do simple addition and subtraction. Strangely, his parents thought it was cute. Every time his son makes a fool of himself, his husband and wife laugh, which makes the rest of us embarrassed and don't understand his virtue. What are husbands and wives proud of? Now I am in junior high school preparatory class, and I am still a poor student. I don't like studying. I'm stupid. I drink hot pot seasoning as soup. I always say that his parents made a fool of themselves, that his father's IQ was zero, and that his mother saw him bump his head against the glass door while eating, and finally embarrassed his parents, hehe. This child is a typical example of parents who have no early education at all. They have no education at all. The child is really not a bad boy, or his life has been delayed.
