What fundamental changes have taken place in China's ancient poetry since the Song Dynasty? What famous poems appeared in Yuan, Ming and Qing Dynasties?

In the Song Dynasty, due to the commercial development, Ci (long and short sentences) was widely circulated in the market, and Ci became the main literary form at that time. Later, the Yuan Dynasty was invaded by foreigners, literature declined, and more folk songs became the mainstream, that is, Song Yuan. In order to express their dissatisfaction with the authorities, many students chose to compose music and write plays, such as Touching Dou E's Injustice, which was at that time. In the Qing Dynasty, storytelling novels replaced songs and became popular at that time.

Works: The Grievance of Dou E, The West Chamber, A Dream of Red Mansions, Thinking of Drinking Water, Peach Blossom Fan, The Palace of Eternal Life, etc.
