 The received legacy of poetry during the Han dynasty includes the classical poetry traditions of the "Shi Jing" and the proto-"Chu Ci".Specific developments of Han poetry included the developments along the lines of these two traditions and the lyrics of folk ballad style as exemplified in the Music Bureau tradition ("yuefu").The development of Chinese poetry does not correspond precisely with the conventional dating of Chinese history by dynasty, despite certain correspondences between the political and poetic trends, with the period of actual transition between dynasties is especially problematic.
