hindsight

後見之明、事後的領悟

With hindsight, I should never have signed that contract.

事後才明白，我當初根本不該簽那份合約。

事後諸葛、後知後覺貶義

It's easy to criticize the decision with the benefit of hindsight.

事後諸葛式地批評那個決定當然很容易。

回頭看來、事後看來

In hindsight, moving to a smaller apartment was the right call.

回頭看來，搬到比較小的公寓是正確的選擇。
