“落井下石”，漢語成語，字面意思是“drop down a stone on the man who has fallen into a well”，比喻乘人有危難時加以陷害（ to maltreat an injured person; add insult to injury; add to the misfortunes of a man who is already unfortunate），與英文俗語“ kick (one) when (one) is down”意思相近，表示“to criticize, exploit, insult, or otherwise treat badly someone who has already suffered a setback or is in a vulnerable position.”

zuì hòu wǒ jiù shì wú fǎ zuò dào zài jí mǐ dǎo méi shí luò jǐng xià shí
