The phrase **恰恰相反** is formed through a combination of an intensifying adverb and a core adjective. The first two characters, **恰恰**, act as a reinforcing adverb meaning "exactly," "precisely," or "just," serving to emphasize and sharpen the tone. They are appended to the core term **相反**, which means "opposite" or "contrary." Together, this structure creates an emphatic four-character idiom that is stronger than simply saying "相反," translating to "precisely the opposite" or "on the contrary," and is used to forcefully correct or contradict a preceding statement in debate or comparison.
