China Question Of Western Postcolonial Translation Theory, Zhijie Wu, Yuping Wang

CLCWeb: Comparative Literature and Culture

“China Question of Western Postcolonial Translation Theory” deals with how western postcolonial translation theory is read, interpreted and applied in China, as well as how the reception in China influences revision and development of the theory. Western postcolonial translation theory, though frequently quoted and highly influential in China, is sometimes incapable of effectively explaining Chinese translation practice and convincing Chinese readers. Based on the analysis of the encounter between postcolonial translation theory and China, three suggestions are proposed to revise translation theory so as to build a “greener,” healthier hetero-generative ecology of languages and cultures.

Cinematic Representation Of Ethnic Minorities In Prc And Postcolonialism, Xinyu Lu

CLCWeb: Comparative Literature and Culture

This paper explores the notions of “Sinophone” and “Chinese-language cinema” under the rubrics of postcolonialism in Chinese film studies both in China and elsewhere around the world. The paper argues that these postcolonial-inspired notions misconstrue Chinese national identity building as imperialist/colonialist endeavours, and dichotomize Han and Chinese ethnic minorities. The paper offers its counterargument by examining cinematic practices of people’s cinema, minority nationality films and native-language films in the PRC.

The Question Of Nation And Nationalism In Chinese Postcolonialism, Yuyu Wu

CLCWeb: Comparative Literature and Culture

This paper examines the impact of postcolonial theory in China on the question of the nation from historical and genealogical perspectives. China first encountered Jameson’s third-world national allegory and Edward Said’s Orientalism, which were quickly assimilated into the framework of the China/West dichotomy. Then Homi Bhabha’s ideas of national identity and cultural hybridity were utilized in studying Chinese ethnic minorities and identity construction. From the earlier views of postcolonialism as cultural resistance to cultural production now, Chinese postcolonial studies have acquired new energy for growth.
