巾jīn

巾 (jīn) is a pictograph so clear that even today it resembles a cloth hanging from a rod — a towel or headscarf frozen in time across three thousand years of script evolution. As a radical, it appears in characters related to textiles and fabrics: 帆 (sail), 幅 (width of cloth), 幕 (curtain), and 币 (currency), showing how this simple visual of a piece of cloth shaped an entire family of meanings.
