What qualities might an effective advertisement have?

Well, I believe the most effective ads create an emotional connection while clearly showing the product's value. Take that Jackie Chan noodle commercial I mentioned - it worked because it combined entertainment with practical benefits. As a UI designer in Shanghai, I notice how short video ads on apps like Douyin often succeed by telling mini-stories that feel relatable. For instance, I recently saw one where an office worker like me struggles to cook after late nights, then discovers a meal kit solution. That balance between real-life frustration and convenient solution makes it persuasive without being pushy. Of course, some ads go too far with exaggerated claims, which just makes people skeptical.
