Ci is a kind of music literature. Its emergence, development, creation and spread are all directly related to music. The music that the lyrics are paired with is the so-called Yan music, also called banquet music. Its main component is a new type of music that has been a fusion of Hu music from the Western Regions and folk lane music since the Northern Zhou and Sui Dynasties. It is mainly used for entertainment and banquet performances. , which became popular in the Sui Dynasty. The origin of the words that go with Yanle can be traced back to the Sui Dynasty. Volume 1 of "Biji Manzhi" by Wang Zhuo of the Song Dynasty said: "Since the Sui Dynasty, the so-called tunes have gradually become popular, and it was slightly more prosperous in the Tang Dynasty." The lyrics were mainly popular among the people at first. There are more than sixty works, most of which are folk songs from the prosperous Tang Dynasty to the late Tang Dynasty and the Five Dynasties. Around the mid-Tang Dynasty, poets Zhang Zhihe, Wei Yingwu, Bai Juyi, Liu Yuxi and others began to write lyrics and introduced this style into the literary world. By the late Tang and Five Dynasties, literati poetry had developed greatly. The late Tang poet Wen Tingyun and the "Huajian" poets represented by him and the Southern Tang poets represented by Li Yu and Feng Yansi were all created. He made important contributions to the maturity of word style and the establishment of basic lyrical style. Ci finally became unique apart from poetry and became one of the most prominent literary genres in ancient China. In the Song Dynasty, the creation of poetry gradually became more and more popular, and a large number of poets with outstanding achievements were produced. Famous works emerged one after another, and various styles and schools emerged. "Complete Song Ci" contains more than 1,330 lyrics and nearly 20,000 poems that have been circulated to this day. From this number, we can infer the grand occasion of creation at that time. Although the origin of Ci is early, the peak of its development was in the Song Dynasty. Therefore, later generations regarded Ci as the most representative literature of the Song Dynasty, alongside the poetry of the Tang Dynasty, and the so-called "Tang poetry and Song Ci" came into being. .
