Li Qingzhao's On Ci has made at least three contributions to the theory of Ci: 1. On Ci puts forward the view that Ci is "another school", which makes it possible for Ci to stand on its own feet outside poetry for the first time and become an independent category, which is tantamount to a declaration of independence of a word. 2. On Ci systematically reviews the historical process of the emergence, development and prosperity of Ci, analyzes the works of poets from the late Tang Dynasty to the Five Dynasties to the Northern Song Dynasty, and puts forward the creative principle of "combining sound with poetry". 3. The Theory of Ci also puts forward a series of valuable concrete opinions on the creative methods of Ci.

She inspected the works of many writers in the past, and put forward a series of valuable opinions on the subject matter, content and expression techniques from rich experiences. For example, the lyrics must be "homophonic"; Writing should have a "narrative"; Words and expressions should be "elegant"; There should be connotation and artistic conception in thoughts and feelings, and "the main emotion is the cause"; The content should be elegant and solemn ("canon"), citing stories and historical facts ("old facts") and so on. The discussion of these specific writing methods is helpful to further enrich and improve the artistic expression of words. Of course, Li Qingzhao only expounds her personal views here, which is subjective and emotional to a great extent, and her comments on some writers are not unbiased, so there is no need to criticize her for perfection. In particular, her evaluation of Su Shi is biased.

Li Qingzhao's ci is fresh, beautiful and elegant, euphemistic and fluent, which generally conforms to her own creative principles. However, in her early works, she broke through the strict rules she set in her thesis. In her later creation, the ideological content is more profound and the artistic technique is more perfect than the creative requirements shown in the paper. This is not surprising. Women writers have a rough life, and they are tireless in art and constantly pursue it, so that they can create a "style of living easily" and pass it on to future generations. In a word, I think there is some internal connection between her creative path and her ci theory. She strictly abides by the principle of "Ci is a family" and thinks that Ci and poetry express their thoughts and feelings in different ways. The so-called "poetic rhyme" ⒂, poetry is a generous ode to lofty sentiments, and words are euphemistic lyricism. She devoted her life to writing lyrics and songs to express her ever-present keen and delicate feelings about external things. Her theory of Ci guided her creative practice, and her creative practice unconsciously broke through the theoretical framework set by her early years and made great strides. Pay equal attention to creative practice and creative theory.
