In the period of Song Dynasties,Literary Selections was spread in the South more flourishingly than in the North.

Since the myth had been created in ancient time,the myth was spread mouth by mouth.

The article provides a detailed discovery of the widespread of Libuyunlue in Song dynasty and its functione by using the historic books of Song dynasty , the references handed down from the ancient times , notes , collected works and the other historical data , which does not only lay solid foundation for the further study on the history of phonetics in Song dynasty.
