Other than a practical social action, accounts of code-choice and code switching in various contexts often signify group membership as well as social identities, which are often strongly marked in later generations of Vietnamese Australians. In addition to seeking possible answers to the question of the mechanism of ethnic retention and cultural reproduction in later-generation Vietnamese immigrants, the paper makes some concluding remarks as implications for language policy and language education to and within communities as a way to maintain the particular culture.20112020-12-20
