Why did Yuanqu appear in the Yuan Dynasty?

First of all, the social reality of the first generation is the foundation of the rise of Yuanqu. The vast territory, prosperous urban economy, grand theater, active book club and all-weather audience laid the foundation for the rise of Yuanqu. Secondly, the exchange and integration of the cultures of all ethnic groups in the Yuan Dynasty promoted the formation of Yuan Qu. Thirdly, Yuanqu is the inherent law of poetry itself and the inevitable result of the inheritance and development of literary tradition.
