go around
匝 centers on circular or surrounding motion: going around, encircling, or making a full circuit.
匝 combines 匚 (a container or enclosure) with 巾 (cloth), possibly suggesting wrapping or encircling with cloth. The exact historical development is uncertain.
Imagine a cloth (巾) being wrapped around inside a box (匚), going around and around until it covers everything.
For キョウ, picture a key going around in a lock: key -> キョウ, and the key makes a full circular turn.
