It's hard to say. Different cartoons have different reasons. If a teenager is full of blood, what he says is "friendship", "victory" and "hard work", which belongs to inspiration and goes forward bravely for his dreams. If a girl is rambling, it is a girl's mind, and most of them are love stories. Different cartoons are drawn by cartoonists, and each cartoon has a different truth expressed by cartoonists. Of course, you still have to understand it yourself, instead of simply reading interesting cartoons (for example, most of them are boys) and then forgetting the true meaning of cartoons and paying attention to places that should not be concerned (such as bears, tun).
