Awarded the Newman Prize for Chinese Literature in 2023, Chang Kuei-hsing's novels hold significant prominence within both the Sinosphere and the world literary space. Yet, how should we approach the force of worldmaking embedded in his rainforest writings, which vividly portray Borneo's wildlife, hidden histories, and even extraterrestrial beings? In this article, I draw on Walter Mignolo's concept of pluriversality to explore how Chang's rainforest writings provide a crucial opportunity to rethink the internal dynamics of both the Sinosphere and the world literary space. By tracing Chang's migratory experience from Borneo to Taiwan, I argue that his rainforest writings not only exemplify the creative evolution of Chinese cultural traditions beyond Mainland China but also demonstrate that, despite the current Western-centric tendencies of world literature, history and literature can flourish richly beyond the Western world.
