Depicts a weapon (殳) smacking a person's buttocks (𡱒). In ancient China, having one's buttocks smacked with a huge stick was one of the punishments criminals could have. Based on the original meaning, "to smack the buttocks". The meaning later shifted to "palace" and "hall", because it was said that buildings have an elevated appearance that stick out like buttocks.
