The ship arrived late to mend the leak

The ship arrived in the middle of the river to fill the hole. It's not helpful to remedy things in time.

It's from Guan Hanqing's "save the wind and dust" in Yuan Dynasty: "at this time of the year, the ship arrived at Jiangxin to mend the leak late. I'm worried about who he is. Think before you do, and you will never regret. " It means that we have not prepared in advance and the temporary measures are not effective
