I don't know. It's not a big problem … because which books will have an impact on children is unpredictable. But in general, as long as it is a "normal" book, it will have some positive effects on people, so don't worry too much. My little nephew liked history very much when he was a child. Later, he was always good at Chinese, and the teacher said that he was very talented. However, the disadvantage is that, later, I failed in math and was finally admitted to junior college ... So, although the problem is not big, as a parent, I have to guide my children to be balanced in all aspects, and I can be good at it, but I don't want to have too much "short board".
