First of all, let's not deceive ourselves: most children hate reading classic books and like comic books that are light and pleasant, because what they want is happiness, not profundity, which is in line with their nature. Classic books are classic because they are profound in thought, and children can't understand them, but they will only feel bored. Reading famous books rather than comics is more for other reasons, such as meeting parents' expectations. Of course, there is no denying that some children do like it.
It's not that children shouldn't read. We need to make clear a few questions first: First, is it more important for children to feel about books, or is it more important to read classics as required now? Second, how big is the ability of seven-and-a-half-year-old children to control their desires? Is it to let him have some desires of his own, or to be completely abstinent?
My suggestion is: give children some power. Don't watch it completely, and don't watch it completely. Make a list of books with him, something he wants to read and something you recommend. If you are in a hurry, you can go and see what his classmates are reading. I remember when I was at school, my teacher forbade me to watch Jin Yong for fear of affecting my study. Now Jin Yong is a master, and the teacher is recommending him.
Whether he will indulge in campus novels and online novels is not simply determined by what books he reads, but by the depth of his thoughts. Reading and reading yourself, the real reading, is that children have a certain sense of self and values, which should be in the late junior high school. Although the third and fourth grades are the outbreak of children's independent reading, more children are interested in stories and still read lightly.
Reading is his own business, especially what to read.
