to take advantage of, to avail oneself of, to follow, to go
趂 centers on moving with purpose: going, following, or seizing an opportunity to act. The core idea is motion that takes advantage of a situation.
趂 combines 走 (run, go) with 尔, which likely contributes a phonetic element. The exact historical development is uncertain, but the structure suggests motion or action.
The running enclosure 走 surrounds 尔, like a person dashing forward to take advantage of an opening. Picture someone sprinting to follow a path and seize the moment.
For チン, imagine a chin-up bar: you go and take advantage of it to exercise, following a routine. Chin -> チン.
