You are wrong. Song Ci is the era of the highest achievement of Ci, but it did not originate from Song Dynasty.
Song lyrics are one of the new-style poems compared to ancient poems. It is a Han literary genre that was popular in the Song Dynasty and marked the highest achievement of Song Dynasty literature.
Ci is a kind of music literature. Its emergence, development, creation and spread are all directly related to music. The music to which the words are matched is the so-called Yanle, also known as Yanle.
It began in the Han Dynasty, was finalized in the Tang and Five Dynasties, and flourished in the Song Dynasty.
It appeared in the Tang Dynasty and was initially popular among the Han people. After the Five Dynasties to the Two Song Dynasties, poetry developed greatly and became the main literary form in the Song Dynasty. Song poetry mainly describes erotic love.
Maybe it was because of the bad luck of the country in the Song Dynasty that people sent their feelings and poems.
