Urban children live in cities since childhood, because the resources in big cities are relatively rich, and urban children will be relatively well informed. Seeing things will be more open-minded and the perspective will be more advanced. Even some will be precocious, encounter many things, see many things, and their values and money views will be relatively advanced; Children in rural areas have lived in rural areas since childhood, and resources will be relatively scarce. I have little contact with things, such as flowers, trees, cats and dogs, my parents and family, and villagers who have grown up there for generations with almost the same cognitive level. There are not so many new people and things for them to perceive and learn.
