攵義a hand with a stick — action done to something
A hand with a stick (攵) goes at what's wrong, tap by tap, until it sits right. 己 jǐ gives the sound — g and j split from one old initial, and the final opened to ai. Together they write to change: 改變、修改、改正.
故事 STORY — a scene to remember it by
木樁歪了，一手扶住，一手拿槌（攵）敲——正過來了。
The post leans; one hand steadies it, the other taps with the mallet (攵) — straight again.
