‘冷风’ literally means ‘cold wind’ — a compound noun formed by combining the adjective 冷 (lěng, ‘cold’) and the noun 风 (fēng, ‘wind’). It refers specifically to wind that feels chilly or biting, often associated with autumn, winter, or sudden temperature drops. Unlike general terms for wind like ‘风’ alone, ‘冷风’ emphasizes thermal sensation and is commonly used in weather descriptions, health warnings, and everyday conversation about comfort and clothing choices.

This word frequently appears in contexts involving physical discomfort (e.g., catching a chill), seasonal transitions, or atmospheric conditions — such as when windows are left open on a cool evening or during windy mountain hikes. It carries a slight connotation of unpleasantness or mild hazard, especially when linked to health (e.g., ‘别吹冷风’, ‘Don’t get exposed to cold wind’). While not poetic or literary, it’s highly functional in spoken and written Mandarin for describing real-world sensory experiences.
