This article explores uninvestigated issues in Cantonese and "Hoisan-wa" language maintenance from an ethnic Chinese diaspora point of view. Data come from a larger study looking at Frog Story narratives from 140 Cantonese-English bilingual children in California. Fourteen of these children were found to display uniquely "Hoisan-wa" phonology and lexicon in their narratives. Focusing on these 14 children, this article attempts to answer the following questions: Due to low prestige factors and lack of support for the maintenance of "Hoisan-wa", have these speakers assimilated to the standard Cantonese-speaking community? Are there any signs that "Hoisan-wa" language backgrounds are still reflected in elementary school students attending schools with a relatively high Cantonese-speaking enrollment? If yes, what are these signs? Because nearly nothing is known about "Hoisan-wa" maintenance in the United States, the author documents markedly "Hoisan-wa" lexicon and phonology, and offers evidence of intergenerational language transmission.
