Since the turn of the 21st century，the imagination of alternative history in Chinese science fiction has been grounded in technological imagination，continually re-examining the enlightenment ideals of democracy and science while exploring a distinctly Chinese sci-fi aesthetic. This is reflected in three aspects: first，the construction of a holistic，cyclic，and unified Eastern philosophy of technology，highlighting the poetic beauty of traditional Chinese craftsmanship; second，the infusion of characters with the Confucian concept of“Yi”，representing righteousness and humanitarian concern，promoting the Chinese ethical spirit of upholding righteousness and embracing innovation; third，the carnivalization of science fiction“New Tales”，filled with wit，humor，and ironic aesthetics，which display postmodern cultural features such as the retreat from historicity and the fragmentation of subjectivity. These explorations demonstrate writers’aspirations to transcend the epistemological framework and cultural aesthetics of Western modernity，to explore and elevate traditional Chinese humanism and rational thought on science and technology，while also capturing the characteristics of postmodernism and expressing concerns for contemporary realities.
