What kind of literary style is popular in each era is also determined by many reasons. There were not so many literati in the pre-Qin period, so the songs of Chu in the Book of Songs became a model for people to learn. The Han, Wei and Six Dynasties were turbulent, and people of different classes had different ideas. Yuefu is a variety of literary works collected by the state from the people. The Tang Dynasty was the heyday of China civilization. Even the understanding of China in other countries and regions in the world is still related to this dynasty. At the same time, with the economic prosperity, scholars have leisure to recite poems, and many poets have emerged. The style of Song poetry is different from that of Tang poetry, and it is also related to economy and politics. The Yuan Dynasty was ruled by Jin people, and the "traditional" culture in the Central Plains developed little, which gradually developed in Goulanwa Temple and other places, laying the foundation for the development of novels and dramas in the Ming and Qing Dynasties.
The above is my humble opinion. It's been several years since I graduated from college. I don't know if there are any mistakes or shortcomings in the narrative, please discuss them more.
