"Song on the Frontier" is a comprehensive composition of Li Fangyuan's five independent ditties "Si Chun", "Zhao Jun Resentment", "Weeping Yan Hui", "Beside the Dressing Table" and "Complaint" in Hua Qiuping's "Pipa Score". The song, named "Song on the Frontier", and the pseudo-support was made by Wang Zhaojun.
The five stanzas of the whole song: 1. Gongyuan Chunsi 2. Zhaojun's Resentment 3. Concubine Xiang's Tears 4. Dressing Table Qiusi 5. Sihan
This song describes Wang Zhaojun's longing for his motherland, which is sad and melancholy, sad and lingering, and has a strong artistic appeal. In playing, it emphasizes the techniques of pushing, pulling, chant, kneading, strumming, and bringing up the left hand, making the melody more euphemistic and soft. The most apt poem to describe this song is the "Xianxian Silences the Sound and Silent Thought" in Bai Juyi's "Pipa Xing".
