Why can't parents who are scolded for using anime wallpapers understand what's wrong with 2D? There was nothing wrong with anime wallpapers as a way of personalizing decoration, but in the eyes of some parents, it might be seen as a form of respect for anime, manga, and other two-dimensional cultures. Therefore, it was difficult to understand why they liked anime wallpapers. In addition, parents might also think that this kind of decoration might make their children rely on cartoons, comics, etc., affecting their children's normal growth. What was wrong with the 2D world? Two-dimensional culture is a virtual world that contains many unique cultural elements and values such as friendship, love, dreams, and so on. Although the two-dimensional culture was loved by young people to a certain extent, it was not the same as real things in the real world. Therefore, we can't simply equate the two-dimensional culture with things in the real world, let alone treat it as a right or wrong value. There was nothing wrong with using anime wallpapers, but parents needed to pay attention to their children's aesthetic education and cultural inheritance to help them rationally view the two-dimensional culture and distinguish it from the real world. Only in this way can we better understand the two-dimensional culture and integrate it into our daily lives.
