Chinese Dongbei Dagu vocal songs, a traditional genre hailing from Northeast China's Dongbei region, possess a rich history spanning over two centuries, distinguished by their unique combination of rhythmic speech-like delivery and melodic elements. The objective of this study is to investigate the fostering of literacy through the transmission of Chinese Dongbei Dagu vocal songs in Xiuyan County, Liaoning Province. The research utilized questionnaires and interviews with six key informants as research tools, including two academic experts, three singers of Dongbei Dagu, and one musical accompanist, who played a pivotal role in providing invaluable insights into various facets of Dongbei Dagu, ranging from its historical significance to the methods employed for its traditional and modern transmission. Qualitative data analysis revealed the existence of two primary modes of transmission: the time-honored apprentice style and the familial family-style methods within traditional settings. Moreover, it uncovered contemporary transmission modes that ingeniously adapt to folk activities, tea houses, theaters, and specialized training workshops. The research findings underscore the paramount importance of cultural databases, governmental support, educational initiatives, innovation, audience expansion, and early education in the continuous preservation and promotion of Dongbei Dagu. Ultimately, this study not only enhances our comprehension of intangible cultural heritage but also offers a pragmatic blueprint for sustaining traditional art forms within the context of contemporary society.
