只要 + Condition, 就 + Result
只要 (zhǐyào) means "as long as" or "provided that" and introduces a sufficient condition for an outcome. It is often paired with 就 in the result clause to indicate that the outcome will naturally follow. Unlike 只有…才, which stresses necessity, 只要…就 presents the condition as easy or minimal to fulfill.
