In Vietnamese, the pronouns 'đấy' and 'đó' are often used to refer to distant objects or people and to recall information mentioned before. Generally, 'đấy' is used when the speaker wants to highlight or emphasize the object, person, or information they are referring to, while 'đó' is more widely used in comparing or contrasting situations. Both are capable to stand alone as pronouns or used with nouns as demonstratives.
