Chinese cotton fluffing (弹棉花 / tán mián huā) is a disappearing traditional handicraft where artisans use a large, bowed instrument and rhythmic plucking to separate, disentangle, and aerate raw cotton, transforming hard clumps into airy, cloud-like batting for warm quilts, a process now mostly replaced by machines. Master craftsmen use a wooden hammer and a special bow, creating vibrations to make the cotton soft, uniform, and ready for stitching into quilts or cushions, a skill passed down through generations but fading away.
