How it's used
Used primarily in formal or professional contexts, this term implies a systematic process of fixing flaws or filling gaps to reach a state of completeness. It is far more common in business, government, or academic discussions than in casual daily chatter between friends. When speaking informally, people often prefer simpler verbs like 改好 or 執靚.
Examples

Common mistake
Learners often use this as a direct synonym for general improvement, but it sounds overly stiff or bureaucratic when applied to trivial personal matters like fixing a messy room or improving one's cooking.
