Origin Story
春秋时期，齐国大臣崔杼弑君。为了掩盖罪行，他强迫史官将齐庄公的死因记录为病死。然而，正直的史官坚持如实记录“弑君”事实，崔杼恼羞成怒，将其杀害。崔杼又杀害了史官的弟弟，但事实依然暴露无遗。最终，弑君的罪行昭然若揭，无法掩盖。这便是“欲盖弥彰”的由来。
During the Spring and Autumn period, Cui Zhu, a minister of the Qi state, murdered his ruler. To cover up his crime, he forced the court historian to record the ruler's death as a natural death. However, the honest historian insisted on recording the truth, "regicide," which enraged Cui Zhu, who had him killed. Cui Zhu then killed the historian's brother, but the truth remained uncovered. In the end, the crime of regicide became undeniable, and this became the origin of the idiom "欲盖弥彰."
