scowl, raise eyebrows
顰 centers on facial expressions of displeasure or concentration: scowling and raising or knitting the eyebrows.
顰 combines 頻 (repeatedly) and 卑 (low, humble), suggesting a repeated lowering or knitting of the brows. The exact historical development is uncertain.
The top 頻 suggests something happening repeatedly, and the bottom 卑 looks like a humble or lowered face. Picture someone repeatedly lowering their brows into a scowl.
For ヒン, imagine a person scowling so hard their face makes a sharp 'hin' sound, like a quick, disapproving sniff: hin -> ヒン.
