Although there are different systems and characteristics in the aesthetic nature of the text content and calligraphy form in calligraphy works, it is undeniable that poetry plays an auxiliary role in calligraphy form. Calligraphy works are often created from poetic content to calligraphy form; Appreciating calligraphy is from artistic form to written content. It is difficult to separate the two, so it can be said that they are one. As a calligrapher, what to write first, then how to write. As early as the Tang Dynasty, Han said in "The Gift of Pen": "If you want to write a book, you must first look at the words and phrases on a piece of paper, how many words are in it and the color of the paper, and what kind of book should be commensurate with it, so that it is consistent with the book, true or true, or lines, or chapters, which are equivalent to paper." Visible content is the forerunner of creation. Poetry is suitable for reciting because of its rigorous structure, elegant rhyme, profound truth and mysterious artistic conception. There are few repetitive words (especially rhyming words and characters) in a poem, and there are few similar glyphs when writing, which is suitable for white cloth. Moreover, excellent poetry not only plays a role as a link between pen and ink, but also plays a role in regulating calligraphers' emotions. Beautiful chapters and sentences can stimulate the calligrapher's creative passion and inspiration, and emotions are contained in the book, thus creating a calligraphy creation process completely different from literary creation, strengthening and improving the artistic effect of calligraphy works, which is more infectious. At the same time, it also enhances the ornamental value. People not only read its books, but also appreciate its articles, which are interwoven into the former. If the content of the book is not continuous or can't be read through and recited, the thinking will not be smooth when writing, that is, it is impossible to write a good work in one go, with a heart-to-heart relationship and no intention of Yoga Yu. If the content is gloomy, plain or tacky, it will definitely affect the calligrapher's play and the mood of the viewer, from which we can understand the mystery that most calligraphers choose to write beautiful poems and couplets.
