Definition
有理有据 is a four-character set phrase (成语) meaning 'to have reason and evidence' — you use it when someone's argument or claim is backed by both logic and facts. It's often used to praise a well-supported statement or to describe a persuasive argument. The literal breakdown is 'have reason, have evidence', and it's a fixed expression; you don't insert words between the characters.
f.e.
