From the Book of Songs to the classical poems of Chu Ci, the transformation from collective singing to individual independent creation was completed, right?

Wrong. Because poetry itself is a process of independent creation, Qu Yuan only opened up a new form of poetry creation, not a change. The book of songs is the product of collective singing, and the songs of Chu are sung independently by individuals. The development of China's poetry from collective singing to individual independent singing is a great leap.
