How did china's geography have an influence on beliefs in ancient china?

China's size, the mountains to the west, northwest, and southwest, and deserts such as the Gobi isolated early peoples from most outsiders. This allowed a distinctive Chinese culture to develop relatively free of outside influences and gave the Chinese a strong sense of identity. The lack of contact also gave Chinese the belief that they were culturally superior to foreign peoples, whom they called barbarians.
