Sanqu flourished in the Yuan Dynasty, which was directly related to the development of language and music. In the Yuan Dynasty, ethnic groups blended together and the population moved frequently. Compared with the Tang and Song Dynasties, pronunciation and vocabulary have undergone many changes. The introduction of music from northern ethnic minorities to the Central Plains also changed the rhythm of poetry creation combined with music. As Wang Shizhen said in "Preface to Qu Zao": "Since the Jin and Yuan Dynasties came to China, the Hu music used was noisy and tense, and the words could not be pressed in between urgent and urgent, but new sounds were used to flatter them." And the city. The development of the economy, the life preferences of businessmen, vendors, and craftsmen, and the vigorous development of popular literature also required the production of poetry genres that could better express the taste of the times. All this is the soil for a new flower to sprout in the world of poetry.

Since the rise of Sanqu, there have been many authors with numerous works, including singing about the love between men and women, describing the scenery of the country, expressing feelings about the world, exposing the darkness of society, expressing thoughts of seclusion, and even nostalgic chants of history and depictions of the city. Style and so on. Since authors from different eras and different experiences have different creative personalities, the music world is also full of gems. Liu Xizai of the Qing Dynasty divided Sanqu into three categories in his "Yi Gai? Qu Gai", the first is clear and deep, the second is bold and broad, and the third is graceful. It can be said that these three products are like three primary colors. They penetrate each other and create colorful colors. Generally speaking, before Yanyou, sanqu writers also wrote poetry, such as Yang Guo, Lu Zhi, etc.; or they were also good at dramas, such as Guan Hanqing, Ma Zhiyuan, etc. Their styles were mostly bold and bold, which can show the sincerity and naturalness of the music. taste. After Yanyou, a group of writers who specialized in Sanqu appeared, such as Zhang Kejiu, Guan Yunshi, Xu Zaisi, etc. Their styles were mostly graceful and beautiful, but sometimes they were less polished. When they tried their best to refine the words, pursue elegance and neatness, move closer to poetic writing, and even "poeticize" it, Sanqu lost its vivid and lively characteristics and began to decline.

The emergence of new aesthetic tastes in the literary world of the Yuan Dynasty, changes in social fashions, theorists' promotion of "emotion" ideas, the influence of the vigorous development of popular literature, the infiltration of ethnic minorities' hobbies of singing and dancing, freehand painting Maturity, and even the rise of personal consciousness, etc., are closely related.
