唐－杜牧《阿房宫赋》：“呜呼！灭六国者，六国也，非秦也；族秦者，秦也，非天下也！嗟夫！使六国各爱其人，则足以拒秦；秦复爱六国之人，则递三世可至万世而为君；谁得而族灭也？秦人不暇自哀，而后人哀之，后人哀之而不鑒之，亦使后人而复哀后人也！”

这是杜牧对“六国”，“秦王朝”，以至秦以后诸王朝的兴亡所发的感慨——后人只知道对前朝哀叹，而不重视借鉴，总是在重蹈覆辙，让自己的后人照样要哀叹自己！

后人复哀

思考秦人不暇自哀而后人哀之后人哀之而不鑒之亦使后人而复哀后人也!

The qin has no time after the sorrowful then person sorrow but the person sorrow the warning also does not cause the posterity but duplicate sorrowful posterity!

与后人复哀相似的词语：重蹈覆辙——follow the same old disastrous road

这次的教训太深刻了，千万不可重蹈覆辙。

The lesson is profound, we'll never recommit the same error.

重蹈覆辙成了一种瘾

Recommit the same error has become an addiction.
