Why do you say "Songs of the South" initiated the tradition of China's romantic poetry?

It consciously uses the principles of romanticism, rich thinking in images, and a large number of myths, fairy tales and fables to create a spectacular realm and a magnificent and noble personality. Prior to this, only myths subconsciously used romantic artistic techniques, and Qu Yuan consciously applied this technique to a brand-new poetry genre for the first time, and then developed into a very mature artistic method.
