bamboo basket
筺 centers on a container woven from bamboo: a basket or box used for carrying or storing items.
筺 combines 竹 (bamboo) with 匤, which likely contributes a phonetic element and the idea of a container. The exact historical development of 匤 is uncertain.
The top 竹 is bamboo, and the bottom 匤 looks like a box with a lid. Picture a woven bamboo basket with a snug lid.
For キョウ, imagine a giant bamboo basket so big it echoes: 'kyoouu' when you shout into it. The echo 'kyo' cues キョウ.
