Let's talk about the achievements of Song Ci. Ci originated from the lyrics of the Tang Dynasty, and the sentences are long and short, which are closely combined with music and can be sung. Due to the development of commerce, the prosperity of cities and the increase of citizens in the Song Dynasty, words that can sing and dance are more suitable for entertainment life in the market than other forms of literary works. At that time, class contradictions and ethnic contradictions were sharp, and irregular sentences were more convenient to express people's thoughts of worrying about the country and the people, so they gradually flourished and replaced poetry as the mainstream of literature. This paper introduces the styles and achievements of Liu Yong, Su Shi, Li Qingzhao, Xin Qiji and Lu You respectively according to the four stages of the early Northern Song Dynasty, the middle and late Northern Song Dynasty and the Southern Song Dynasty. Liu Yong is an important representative of graceful and restrained school in Northern Song Dynasty. He has lived in the city for a long time, and his works mostly show the prosperity of the city and the feelings of joys and sorrows of men and women, especially the loneliness and homesickness during the journey. Most of his words are colloquial, popular and vivid. "Wherever there is a well water, you can sing Liu Ci" (Ye Mengde: Summer Tale), so it is widely circulated. His ci works also incorporate a lot of narrative elements, which not only expands the realm of ci, but also opens the door for the development of Yuanqu. Su Shi was the pioneer and main representative of the uninhibited school in the middle and late Northern Song Dynasty. His ci has a wide range of themes, which greatly expands the content of ci and injects great vitality into heroic and unrestrained ci. Li Qingzhao was an outstanding graceful and restrained poetess in the early Song Dynasty. She put forward the idea of "different words" and is good at expressing her true feelings with simple words and expressions. Xin Qiji and Lu You, a poet in the Southern Song Dynasty, advocated active resistance to gold, and their works were mainly bold and unrestrained, which profoundly expressed their strong desire to restore the Central Plains. Su Shi and Xin Qiji are the most representative and accomplished poets in the Song Dynasty, and their lives are introduced in the column of "History" and illustrations respectively. It must be pointed out that bold writers in Song Dynasty mainly wrote bold works, but they also wrote some very touching and graceful words, not just bold ones.
