布帘 (bù lián) literally means 'cloth curtain' — 布 (bù) means 'cloth' or 'fabric', and 帘 (lián) means 'curtain' or 'drape'. Unlike heavier curtains made of velvet or synthetic materials, a 布帘 is typically lightweight, soft, and often used in informal or functional settings like separating rooms in small apartments, covering doorways in traditional shops, or adding texture to modern minimalist interiors. It’s valued for its simplicity, breathability, and ease of washing.

This term emphasizes material composition rather than decorative function, distinguishing it from more formal terms like 窗帘 (chuānglián, 'window curtain') or 纱帘 (shālián, 'sheer curtain'). While historically common in rural homes and street-side stalls, 布帘 is now also popular in contemporary design for its rustic charm and eco-friendly appeal. It’s rarely used metaphorically and almost always refers to a physical hanging textile barrier.
