Etymology

改 combines 己 (self) with 攵 (action, hand with a stick), suggesting the idea of changing oneself or taking action to reform.

Meaning mnemonic

The left side 己 looks like a coiled self, and the right side 攵 is a hand holding a stick. Imagine using the stick to reshape yourself—reforming and changing for the better.

Reading mnemonic

For カイ, picture a person named Kai who is always reforming things: Kai -> カイ, and Kai is busy modifying and mending everything.
