This article reports on an ethnographic case study that explored how Chinese learners' national identities were displayed and reconstructed through their English language-learning journeys in Britain. Drawing on a variety of sources (ethnographic observations, informal conversations, diaries, and narrative interviews), the analysis focuses on the Chinese learners' raising self-awareness of being Chinese and their attitudes towards Japanese students, South Korean students, and students from Taiwan. This study found that during their English language learning journeys in Britain, the Chinese learners tended to affirm and often displayed their membership with respect to China and Chinese national imagination, which contributed to heightened senses of Chinese national identity and increased patriotism. At the same time, the experience of interacting with Japanese students, South Korean students, and students from Taiwan encouraged the Chinese learners to question and critically reexamine their own attitudes and values related to their national identities. Then, the elements that made up an individual's Chinese national identity were brought under scrutiny and negotiation. Implications for classroom practices are also discussed.
