Both Chinese and Western literary and artistic creation embody perfect man thinking. Perfectionism in ancient Chinese literature and culture is more common and thorough than that in the West. The gods in ancient Greek and Roman mythology show their own defects, which is in sharp contrast with the supreme, perfect character of gods in Chinese literary and cultural tradition. The thorough perfect man thinking makes Chinese mythology have obvious tendency of God standard, while the Western mythology system has obvious tendency of people-centeredness. The myth of the tendency of God standard treats gods and heroes from the perspective of looking up. This thinking tradition has a profound impact on the creation of contemporary Chinese fantasy literature, which makes it show obvious differences from Western fantasy literature.
