What is the new poetic style of Chu's use of local dialects in the Spring and Autumn Period? Who is the founder of this new poem? What is the masterpiece?

During the Warring States period, Chu poets absorbed the essence of southern folk songs, merged ancient myths and legends, and created a new poetic style-Chu Ci. The appearance of Chu Ci is the great liberation of China's ancient poetry. It breaks the rigid format of "four words and one sentence" in The Book of Songs, adopts irregular sentence patterns of three to eight words, with lively and diverse forms, suitable for describing complex social life and expressing rich thoughts and feelings, and its length and capacity can be expanded at will according to the needs of the content. Qu Yuan, a great poet, is the founder and representative writer of Chu Ci.

Li Sao is the most mature work of Qu Yuan and the most magnificent lyric poem in ancient China. The first half is a realistic narrative, which describes his ideals and experiences of improving politics. A lot of strange fantasies were added in the second half. Accompanied by wind, rain, thunder, electricity, clouds, moon, phoenix and dragon, he galloped up and down in the sky, pursuing his ideal object. The result was disappointing.

The poet integrated natural phenomena, historical figures and legends into a magnificent and romantic artistic image, realizing a high degree of integration of thought and art. Lu Xun praised Qu Yuan and said, "Escape is a big talk, and you will be outstanding all your life."

Tian Wen is a strange long poem. This is because after Qu Yuan was exiled, he lost his mind and his old beliefs completely collapsed. Therefore, he had doubts about natural phenomena, ancient ruins, religious beliefs and traditional concepts of society, which led to various questions. By asking questions, the poet vented his contradictions and pains in political life.
