The metaphor of ＂hospitalization＂ is often used to symbolize the degree of language endangerment in Taiwan. Taiwanese (Taigi) comparatively is less severe and ＂treated in an outpatient department,＂ as its users occupy the majority of language population in Taiwan. A new description of the symptom of language shift is ＂Oat-thau-cheng＂ (symptom of turning-head), as a depiction of the improper conduct in which parents talk to each other in Taiwanese but speak with children in Mandarin Chinese. Such undue behavior, as inappropriate family language management, is critical to the loss of the mother tongue. Family is a key domain where a mother tongue is maintained. How parents' family language management takes its toll on mother-tongue maintenance is the main focus of the article. From the perspective of family language management, this article analyzes the maintenance and loss of Taiwanese in southern Holo families, centering on the discussion of family language policy and language management. The research results demonstrate that some southern Holo parents are short of effective family language policies and language managements. The inadequacy of family language policies brings about the potentiality of that Taiwanese is replaced with Mandarin and thus becomes an endangered language. Language policy and management both are highly associated with making changes in language use. Hence, the authors suggest that parents should actively step in to formulate family language plans through which family language environment is established to reverse the language shift. For the promotion of intergenerational transmission of Taiwanese, this article provides several practical alternatives appertaining to the strategies of language maintenance and suggestions on the follow-up of family language revitalization
