Basket

basket, devote oneself, seclude oneself, cage, coop, implied

Mnemonic

A bamboo weaver crafted an enormous basket to trap a dragon. The dragon thrashes and breathes fire inside, but the enchanted bamboo holds firm — it won't burn or break. This basket is no ordinary container; it's a cage strong enough to confine a mythical beast forever.
Additional thoughts
Picture the basket as a woven bamboo prison. The dragon locked inside reinforces both the physical 'cage/basket' meaning and the abstract sense of confinement or seclusion this kanji carries.
Quick recall
A bamboo cage-Basket locks a dragon inside forever.

Details

The keyword for 籠 is basket. This kanji refers to a woven container, typically made from bamboo, used for carrying or storing items. It can also convey the idea of being enclosed or confined, as in shutting oneself away in a place, evoking the image of being contained within a cage-like structure. The character thus carries both the concrete sense of a physical basket or cage and the more abstract sense of confinement or seclusion.
