The origin of Idioms

The third part of Ming Dynasty's Wu Mingshi's "Sanhua Handan" is: "you can't find an escape plan when you are a prisoner holding an official. You can't turn back quickly until you regret coming late, and you don't tie up your heart and mind. It's not that your nature can't be changed and your old illness can't be cured."
