I regret it too late, I regret turning over, I regret that I didn't, I don't repent, I regret it again and again ... I don't hesitate to regret it when time is out of date, and I don't regret it when my hair is black. The longest and shortest, fastest and slowest, most common and most precious, most easily overlooked and most regrettable thing in the world is time. Cao Cao killed Lu Bu-it's too late to regret it;

Mother-in-law stamped her foot-it's too late to regret it.
