This article leverages interview data from students of Chinese who enrolled at a UK university but pursued a period of study abroad in China, aiming to delve into their negotiation of language identities during their overseas experience. By employing Block's structural model in our discourse analysis, this research reveals the dynamic interplay between agency and structure, shedding light on the intricate process of language learning and identity formation. The findings underscore that structural contexts are integral to shaping students' agency, highlighting specific structural spheres that pose challenges to their development of Chinese language and multilingual identities. These spheres encompass the linguistic and cultural dominance of English as well as Chinese hospitality practices. Rooted in their habitus, participants' preconceived notions of the Chinese language and cultural aspects influence their journey, yielding either positive or negative impacts. Furthermore, participants' backgrounds and prior language learning experiences significantly contribute to their identity development. In advocating for a comprehensive approach, this study emphasises the integration of both agency and structural contexts as necessary to fully comprehend the intricate process of identity development.
