(2) Taking poetry as ci only breaks the limitation that ci can't describe a wide range of subjects, that is, it narrowly reflects the love between men and women in sanhua and extends to other aspects of literati's life more broadly.
(3) This does not mean that we can ignore the differences between poetry and ci. Su Ci is not only different from Su Shi in style, but also different in emotional charm. On the one hand, Su Shi innovated the style of Ci, on the other hand, he kept and maintained the characteristics of Ci, and paid attention to giving full play to the advantages of rhythm, irregular sentence pattern and loose rhyme, thus creating a unique poetic environment that his ancient and modern poems could not have.
(4) Su Shi wrote poems, which is the origin; He also "returned words with words" to complete his true colors, so his innovation of ci style will achieve amazing success.
The technique of "taking poetry as ci" is Su Shi's main weapon to change the style of ci, that is, transplanting the expression of poetry into ci, breaking through the restriction and restraint of music on ci, and turning ci from an accessory of music into an independent lyric poem. This sentence comes from Chen Shidao's Poems on the Back Hill: "Shi Yu said: ... Su Zizhan's poems are like poems, and Qin Shaoyou's poems are like poems". From the standpoint of respecting the style, Chen Shidao denied Su Ci with non-authenticity, but just revealed the contribution of Su Ci.
