木已成舟, 大局已定

an unchangeable decision has been made or an irreversible action has been taken

:
After submitting my resignation, I knew the die was cast and there was no turning back.
提交辭職後,我知道木已成舟,無法回頭了。
Once you sign the contract, the die is cast, and you're committed to the terms.
一旦你簽署了合同,木已成舟,你就必須遵守條款。
