push (people) back, reject
擯 centers on forcefully pushing people away or rejecting them, often in a social or ceremonial context. The idea is to expel or keep someone at a distance.
擯 combines 扌 (hand) with 賓, which likely contributes both sound and the idea of a guest or visitor. The hand radical suggests an action of pushing or rejecting a guest, fitting the meaning of expelling or keeping someone away.
The hand radical 扌 beside 賓 (which can suggest a guest) paints a scene of using your hand to push a guest away or reject them at the door.
For ヒン, imagine a bouncer pushing back a rowdy guest with a firm 'Hin!' sound: Hin -> ヒン, and the hand rejects the unwanted visitor.
