school
庠 centers on a place of learning: a school, especially in a classical or institutional sense.
庠 combines 广 (building with a roof) and 羊 (sheep), likely representing a place where sheep were kept or sacrificed, later extended to mean a school or hall of learning.
Under a roof (广), a sheep (羊) is being taught—imagine a school where even animals learn.
For ショウ, picture a show-and-tell at school where a sheep is the star: show -> ショウ, and the sheep is under the school roof.
