This paper employs the theories and methods of music anthropology to conduct a deep analysis of the newly composed Guangdong Han Opera “Tianfeng Haiyu Meihuadu.” By exploring its musical forms, performance rituals, and the cultural connotations of the Hakka people, it reveals the unique cultural memory embedded in the musical aspects of the opera. The study finds that “Tianfeng Haiyu Meihuadu” is not only a representative work of the newly composed Guangdong Han Opera but also an important carrier of Hakka cultural inheritance and dissemination. Its music and performance are closely linked to the history, emotions, and social life of the Hakka people, providing a vivid example for understanding the characteristics of Hakka culture and the functions of musical culture.
