This paper applies the intertextuality theory and takes 18 representative works as examples including the text of Zhuang folk songs of Napo, Pingguo, Longzhou and other areas and the text of the contemporary Guangxi vocal music works, to conduct a comparative study. Then, it is found that the text of contemporary Guangxi Zhuang vocal music works has distinct national textual characteristics of the Zhuang nationality in the four aspects of music language, music style, performance form and stage costume. Such results are conducive to the inheritance and development of Guangxi national vocal music works, and provide theoretical reference for the creation and research of Guangxi national vocal music.
