From the whole history of calligraphy, after the Tang Dynasty, we can see that the Song Dynasty attaches great importance to interest. Yan Liang, a Qing man, said "Yan of Jin Dynasty, Yan of Tang Dynasty, Yan of Song Dynasty, Yan of Yuan Dynasty and Yan of Ming Dynasty." It basically summarizes the characteristics of calligraphy and the aesthetic orientation of artists in these historical periods. "Jin Rhyme" and "Song Yi" are two representative aesthetic propositions in the history of Chinese calligraphy. It is the aesthetic judgment of later readers in the process of spreading, appreciating and accepting the calligraphy of Jin people and Song people. They are not only the historical and cultural accumulation of the Chinese nation, but also the theoretical crystallization of the aesthetic consciousness of The Times. The slips and writings of the Jin people have a unique elegant charm, which naturally emerges from the lines. The "rhyme" of the Jin people's calligraphy is flowing slowly from the mysterious speculative wisdom. A prominent feature of the aesthetic thought of "Shang Yi" calligraphy in Song Dynasty is to emphasize the entertainment and lyrical expression function of calligraphy art, and to make books and write books as elegant things for literati and officials to cultivate temperament and self-cultivation.
