How it works
V了就V了 shrugs off something already done as not worth worrying about — "so what if it happened; it's over". It often adds a follow-up about moving on.
Examples
丢了就丢了,再买一个吧。
Diū le jiù diū le, zài mǎi yí ge ba.
If it's lost, it's lost — just buy another.
错了就错了,下次注意。
Cuò le jiù cuò le, xiàcì zhùyì.
So you made a mistake — be careful next time.
走了就走了,不必再想他。
Zǒu le jiù zǒu le, búbì zài xiǎng tā.
He's gone, and that's that — no need to keep thinking about him.
