The smart range hood's "Stir-fry mode" doesn't simply increase suction power; it automatically adjusts the air speed based on oil fume concentration. A truly effective kitchen relies on a balance between people and technology—running at full power when hot, then reducing the air speed just before serving to ensure the aroma lingers on your tongue. "Even when the heat is right, the air should be reduced"—this is not only culinary wisdom, but also a matter of moderation in life.
