It is generally believed that the phrases of "xiali baren", "yang'e xielu" and "yangchun baixue" from SONG Yu's "Answers to the Questions of the King of Chu" in the Selected Literary Works (Wenxuan) refer to the titles of six verses, that is, "Xiali", "Baren", "Yang'e", "Xielu", "Yangchun" and "Baixue". Based on the new and old unearthed materials, it can be concluded that they are actually the titles of three ancient verses, that is, "Xiali Baren", "Yang'e Xielu" and "Yangchun Baixue". The traditional misunderstanding is due to the special habit of citing the names of these verses in the Han and Wei Dynasties. Clarifying the titles of ancient verses plays an important role in re-understanding the new folklore music in the Warring States Period, which also help us realize the comprehensive reform of the traditional music represented by The Book of Poetry (Shi Jing) in the Spring and Autumn Period and the Warring States Period.
