As a linguistically heterogeneous nation, China has 290 languages and nearly 2000 distinct "fangyans" (dialects or subdialects) with "Putonghua" as the national language. These languages and language varieties are hierarchically ranked, based on their wider communicative and socioeconomic values. This paper reports on how "Putonghua," "fangyans," and English are perceived by a group of Chinese middle-class parents and how parents as agents of language policy provide affordances and constraints in facilitating or limiting their children's language development in English, "Putonghua" and "fangyans." The study involves eight Chinese city-dwelling families with children aged 5-11 years. By examining the children's family language audits, observing their language/literacy practices, and engaging in conversation about parental language ideologies, the study aims to understand how public discourse about different languages or "fangyans" and their perceived values shape parental involvement in their children's language development. The results of the study suggest that parents as agents of decision making have a strong influence on the changes of linguistic ecology in China in urban contexts.
