Quote famous sayings in double quotation marks. When quoting famous sayings, it should be noted that if you quote what a famous person said during the dialogue, you should emphasize what a famous person said through quotation marks, and the punctuation at the end of the sentence should be put in quotation marks. Besides this, if you want to quote a famous person, the punctuation of the quoted words should not be put in quotation marks. If there are commas in the quoted famous sentences, there should also be commas in the quoted sentences.
