The integration of cross-cultural inquiries into the realm of translation has given rise to a distinct subfield known as cross-cultural translation studies.This approach emphasizes the importance of delving into the cultural subtleties and the awareness of cultural subjectivity within the translation process.Central to this framework is the concept of reshaping cultural nuances and the subjectivity of culture.This paper introduces three principal translation strategies that emerge from a cross-cultural standpoint:the alienation translation strategy,the‘cannibalism’translation strategy,and the destructive translation strategy.Utilizing the English translation of“Dream of the Red Chamber”as a case study,the paper examines how cultural nuances and cultural subjectivity influence the selection of translation strategies and demonstrates the practical application of cross-cultural research within the translation sphere.Hence,the significance of cross-cultural translation studies lies in its capacity to offer a novel lens through which to view translation studies.It encourages a reevaluation of cultural nuances and subjectivity in translation,which is of profound practical importance for advancing the field of translation studies,enhancing cross-cultural communication,and facilitating the spread of Chinese discourse on the global stage. 展开更多

As a kind of widely circulated folk language,two-part allegorical saying(“xiehouyu”)carries the wisdom of the Chinese people and is characterized with humor and vivid imagery.Taking the two English translation versions of A Dream of Red Mansions as examples,this paper analyzes the English translation of two-part allegorical saying based on the core principle of Embodied Cognitive Linguistics(ECL),“Reality-Cognition-Language”,and explores how the English translation of two-part allegorical saying reflects the three dimensions of ECL. 展开更多
