We should consider who are the main consumers in the book market. According to my observation for many years, there are still many children. Even if adults buy books, most of them rarely bring illustrations, but the purchase volume is still not as good as the former. Looking at the center of household consumption, children are basically the mainstay. For families with children, most of their consumption content revolves around children, so parents will invest money in their children. So the prospect of making children's books should be good. It's just that the current market is not standardized, but it depends on the consumer groups before deciding the direction.
