After the literary foundation was too deep, the literary world in the Northern Song Dynasty dominated, and the literary status of Ci was also comprehensively improved. Su Shi's ci has another major feature.

Allusions are extremely deep, showing the width of depth, not just a single sentence, but also the span of the whole word is very large and dynamic, giving people a vast and boundless realm. Su Shi's poems are like the sea. How did this come about? Another is that Su Shi's poems are well written and expressed in the same way. There are more than 2,000 words, more than 3,000 poems, and more articles, including essays and works. When Su Shi was in prison, he remembered all the poems written many years ago, which was very exaggerated. He remembers all the poems he heard from others very clearly. When Su Shi was arrested, he told his family a joke on the spot, including a poem written by someone else. He still remembers that he memorized all kinds of classic books and didn't bring any books when he went to Hainan, but he finally wrote The Analects.

Xin's words feel stiff and thoughtful. The argot that moths think of has almost no allusions, or is very dull and poor in expression. Therefore, the conclusion given to Xin by later generations is that writing Ci in words is also an uninhibited school in the branch of Su Ci. The theme is relatively simple, and the number of works is around 600. Xin is a patriotic poet, not an official.
