Yue-fu poetry originated from folk songs, and most of the early days of Yue-fu poetry were accompanied by music. For this reason, not only musical symbols can be seen in the lyrics of Yue-fu poetry in the Han Dynasty, but also various rhetoric are frequently used. These rhetoric have in common that they repeat in form and meaning with a slight change in font and content, creating a unique rhythm in the lyrics. Among them, the ding-zhen that resembles Japanese word chain game and the antithesis that contrasts two similar phrases play an important role in characterizing Yue-fu poetry as a song. This paper study the characteristic rhetoric of folk songs in the Han dynasty, which are found in "Gu-chui quci" and "Xiang-he geci". The second chapter explores the effect of the ding-zhen on poetry, and the third chapter explores aspects of the antithesis.
