2. The Ci of Chu is a new style poem that originated in the Chu area of the southern Yangtze River valley in the middle and late Warring States period. Chu poets absorbed the essence of southern folk songs and integrated ancient myths and legends. Songs of the South broke the rigid format of the Book of Songs, which was a great liberation for the development of China's ancient poetry and also opened the second spring of China's epic. "Songs of the South" adopts a sentence pattern of three to eight words, and its length and capacity can be expanded as needed. The vivid and diverse forms make Chu Ci more suitable for describing complex social life and expressing rich thoughts and feelings.
