Literature is presented to people by language as material material. A literary work, a literary image, can only be printed in the form of language on paper and other planes, and then for people to read. Left the language, literature can not exist. The ancient literary theory in our country divides literary works into four levels: "language" (language), "image" (image) "meaning" (meaning), "Tao" (essence). In these four aspects, language is the most basic: language shapes the image, the image determines the meaning, the meaning contains the essence. Without language, none of the other three dimensions of the work exist and they must both be carried over to the language. This shows that language is the most basic and most basic thing in literature. https://www.journalfirst.net/language-is-the-essential-characteristic-of-literature-from-other-disciplines-of-the-arts.html
