The study focuses on the preservation and transmission of Gannan Tea Picking Opera knowledge after the Cultural Revolution in 1949 using qualitative research methods such as interviews and observations with seven key informants. The following findings were obtained, which can be divided into three distinct periods: The tortuous development phase from 1949 to 1966 marked significant growth and development, with the establishment of specialized schools and the implementation of the "three reforms" contributing to knowledge transmission and preservation. The survival dilemma period from 1966 to 1976 during the Cultural Revolution imposed constraints on artistic expression, but the return of artists from rural areas and their role in recruiting apprentices supported the continuity of Gannan Tea Picking Opera. Finally, the Ganzhou Gannan Tea Picking Opera Troupe and educational institutions contributed to the revival of this traditional art form during the period of rebirth from 1976 to 2023. Retired artists continue to play a vital role in knowledge preservation and dissemination, reflecting the enduring resilience of Gannan Tea Picking Opera.
