The function of quotation is to make the argument conclusive, convincing, inspiring, concise, implicit and elegant. In order to make the language more convincing and authoritative, and enhance the aesthetic feeling and cultural connotation of literature, some famous sayings are often quoted.

Famous sayings are classic works and authoritative speeches, which generally include famous sayings, epigrams, ancient poems and famous sentences. In argumentative writing or comprehensive writing, the author often uses famous sayings as theoretical arguments to demonstrate his views.

Take the argument as the commander-in-chief and always serve the argument. Generally speaking, quoting famous sayings at the beginning of an article can play the role of outlining, arousing the whole body, attracting attention and laying the tone for the whole article.
