Chuci, also known as "Chuci", is a poetic style created by Qu Yuan, a great poet in the Warring States Period. The works use the literary style and dialect rhyme of Chu area (now around the two lakes) to describe the mountains, rivers and historical customs of Chu area, which has strong local characteristics. In the Han Dynasty, Liu Xiang compiled Qu Yuan's works and Song Yu's works "Chengqu Fu" into a collection of poems named Chu Ci, which had a far-reaching influence on China literature after the Book of Songs. Chu Ci is China's first collection of romantic poems.
