• Pinyin (with tone marks): yī shī zú chéng qiān gǔ hèn
• Part of Speech: Chengyu (成语) / Idiom
• HSK Level: N/A (Advanced)
• Concise Definition: A single misstep can become a regret that lasts for a thousand generations.
• In a Nutshell: This isn't about spilling your coffee or being late for a meeting. This idiom describes a catastrophic, life-defining mistake. Think of a single bad decision—like committing a crime, cheating on a crucial exam, or getting into drugs—that sends your entire life spiraling downwards. The feeling is not just simple regret; it's a deep, eternal remorse for a past that can never be changed.

• 一 (yī): One; a single.
• 失 (shī): To lose, miss, or make a mistake. Here it implies a “misstep” or “error.”
• 足 (zú): Foot; by extension, a step.
• 成 (chéng): To become; to turn into.
• 千 (qiān): A thousand.
• 古 (gǔ): Ancient; of ages past. Together, 千古 (qiān gǔ) means “for all time” or “eternal.”
• 恨 (hèn): Hatred, sorrow, or deep regret.

The characters literally combine to paint a vivid picture: “One lost step (一失足) becomes (成) a thousand-year regret (千古恨).” The imagery is both physical (a misstep on a cliff) and metaphorical (a moral or ethical failing).

This idiom reflects a deep-seated cultural value of caution, foresight, and the immense weight of one's reputation and life path. In Chinese culture, where individual actions are often seen as reflecting on one's entire family and lineage, a single major failing can bring shame that feels eternal. A useful Western comparison is the phrase “A moment of madness, a lifetime of regret.” However, `一失足成千古恨` carries an even greater sense of historical and generational weight. The “thousand years” (千古) hyperbole suggests that the consequences of the mistake are so profound that they echo through time, affecting not just the individual but their legacy. This contrasts sharply with a more forgiving Western concept like “Everyone makes mistakes” or “Don't cry over spilt milk.” While those phrases encourage moving on from minor errors, `一失足成千古恨` serves as a stark warning about the kind of mistakes you *cannot* move on from. It is a cautionary principle taught by elders to the young, reminding them that some choices have permanent consequences.

This is a formal and literary idiom. You won't hear it used in casual, everyday conversation about trivial matters. Its usage is reserved for serious situations.

• As a Warning: It's frequently used by parents, teachers, or mentors to warn young people about the dangers of drugs, crime, academic dishonesty, or other life-ruining behaviors. It's a way of saying, “Don't even think about it, because one mistake could destroy everything you've worked for.”
• In Retrospect: It is used to describe the profound regret someone feels after their life has been ruined by a past mistake. You might see it in news articles about corrupt officials who are caught, or in dramatic films where a character reflects on their downfall.
• Connotation: The connotation is entirely negative and solemn. It is a phrase heavy with the weight of tragedy and finality.

• Don't Overuse It: The biggest mistake for learners is using this idiom for minor problems. Its power comes from its rarity and gravity. Applying it to everyday frustrations will make you sound overly dramatic and even comical.
  • Incorrect: 啊，我忘了带钥匙，真是一失足成千古恨！ (Ā, wǒ wàng le dài yàoshi, zhēnshi yī shī zú chéng qiān gǔ hèn!)
  • Why it's wrong: Forgetting your keys is an inconvenience, not a life-ruining catastrophe. A native speaker would just say “真倒霉 (zhēn dǎoméi)” - “What bad luck!” or “真麻烦 (zhēn máfan)” - “So annoying!”.
• It Implies Irreversibility: This idiom is used for situations where there is no going back. If a mistake can be fixed or learned from, a different phrase like 亡羊补牢 (wáng yáng bǔ láo) - “mend the pen after the sheep is lost” - would be more appropriate. `一失足成千古恨` implies the damage is permanent.

• 后悔莫及 (hòuhuǐ mò jí) - To regret something so much that it's too late to do anything about it. This is a very close synonym and captures the same feeling of irreversible regret.
• 三思而后行 (sān sī ér hòu xíng) - Think three times before you act. This is the preventative medicine for avoiding a situation of `一失足成千古恨`.
• 前车之鉴 (qián chē zhī jiàn) - The overturned cart ahead is a warning to the carts behind. This means learning from the catastrophic mistakes of others to avoid the same fate.
• 一步走错，步步错 (yī bù zǒu cuò, bù bù cuò) - One wrong step leads to all subsequent steps being wrong. This describes the domino effect that a single initial bad decision can have.
• 亡羊补牢 (wáng yáng bǔ láo) - To mend the sheep pen after the sheep has escaped. This is an optimistic counterpart, suggesting that it's better to fix a mistake late than never. It's used for problems that *can* be mitigated, unlike `一失足成千古恨`.
• 人非圣贤，孰能无过 (rén fēi shèngxián, shú néng wú guò) - People are not saints, who can be without fault? This idiom expresses the idea that everyone makes mistakes and promotes forgiveness, standing in philosophical contrast to the unforgiving finality of `一失足成千古恨`.
