重蹈覆辙 Repeat the same mistakes
Explanation
比喻不吸取教训，再走失败的老路。
A metaphor for not learning from mistakes and repeating the same failed path.
Origin Story
东汉时期，权臣梁冀专权，残害忠良，最终被桓帝诛杀。然而，桓帝为了巩固统治，重用宦官，结果宦官专权，导致朝廷腐败，天下大乱。历史总是惊人的相似，桓帝的行为正如同重蹈梁冀覆辙一般，最终导致了东汉的衰败。这便是重蹈覆辙的真实写照。桓帝本想依靠宦官来巩固自己的权力，却忽略了宦官的贪婪和野心，最终被他们所利用，导致了国家的衰败，这正是重蹈覆辙的悲剧。这既是历史的教训，也是后人的警示。
During the Eastern Han Dynasty, the powerful minister Liang Ji abused his power, persecuted loyal officials, and was eventually executed by Emperor Huan. However, Emperor Huan, in order to consolidate his rule, reused eunuchs, resulting in eunuchs abusing their power, leading to corruption and chaos in the court. History often repeats itself, and Emperor Huan's actions were like repeating Liang Ji's mistakes, ultimately leading to the decline of the Eastern Han Dynasty. This is a true portrayal of repeating the same mistakes. Emperor Huan wanted to use eunuchs to consolidate his power but overlooked their greed and ambition, ultimately being used by them, leading to the decline of the country. This is a tragedy of repeating past mistakes. This is a lesson from history and a warning for future generations.
Usage
