事后他很后悔。
He regretted it afterwards.
after the event; in hindsight; in retrospect
Every character draws itself, stroke by stroke. Then grab the brush: trace it yourself and hear the word when you finish.

Chinese words snap together like bricks. Every word below shares a character with this one, so you are already halfway to knowing it.

He regretted it afterwards.
事后再说也不晚。
It is not too late to talk after.
