Tips

history
From 》(Du Mu, Late Tang, 825), a fu-prose piece on the fall of the Qin: 而后后人使后人后人 (The Qin had no time to mourn themselves, so later ages mourn them; if those later people only mourn without taking warning, they too will make still-later people mourn them). Du Mu's circular warning — mourning without learning guarantees repetition.
usage
Inseparable from the fuller sequence / 而后 / 后人 / 使后人后人. = to mourn, lament. = them (object pronoun). A favored quote in Chinese historiography and reform debates.
