Tips
usage
鬓 is often used in compounds: 鬓角 (bìnjiǎo, temples/sideburns), 鬓发 (bìnfà, hair at the temples), and 鬓毛 (bìnmáo, hair on the temples). Poets frequently use the whitening of the temples as a metaphor for aging.
Top hair radical 髟 — the long-hair Kangxi radical, drawn as 镸 long combined with three flowing strands. It indexes 鬓 and the whole hair family: 髪 hair, 鬃 mane, 鬚 beard, 髻 topknot. Anything tied to hairstyle or facial hair takes this top cap.
Bottom 宾 supplies the sound — bīn shifts to bìn, only a tone change. The traditional form was 鬢 with phonetic 賓; the simplified 宾 inherits that role unchanged. 鬓 names the hair at the temples, the patch that greys first in classical poetry about ageing.
