• Pinyin (with tone marks): jū ān sī wēi
• Part of Speech: Chengyu (四字成语), Verb Phrase
• HSK Level: N/A (Chengyu, considered advanced but widely known)
• Concise Definition: To be mindful of potential dangers even in times of security and stability.
• In a Nutshell: Imagine your company just had its best year ever. Instead of throwing a huge party and relaxing, your boss calls a meeting to discuss potential new competitors and future market shifts. That's 居安思危. It's not about being a pessimist; it's about being a realist. It's the wise, calm mindset of using periods of strength and stability to build defenses and plan for inevitable future challenges. It's the opposite of resting on your laurels.

• 居 (jū): To reside, to live in, to be in a certain state.
• 安 (ān): Peace, safety, security.
• 思 (sī): To think, to consider, to contemplate.
• 危 (wēi): Danger, crisis, peril.

When combined, the characters literally mean: “To be in (居) a state of peace (安), yet think about (思) danger (危).” The meaning is direct and profound, highlighting a core principle of foresight.

• Originating from the ancient text Zuo Zhuan (左传), 居安思危 is deeply embedded in the Chinese cultural psyche. It reflects a long-term, cyclical view of history, where periods of prosperity are often followed by turmoil. This isn't seen as pessimistic, but as a pragmatic understanding of the world. The proverb serves as a constant reminder for leaders, businesses, and individuals to avoid the hubris that can come with success.
• Comparison with Western Concepts: A close Western equivalent is the Boy Scout motto, “Be Prepared,” or the saying, “Hope for the best, prepare for the worst.” However, 居安思危 is more of a continuous mindset than a one-time action. While “preparing for the worst” might involve packing an emergency kit, 居安思危 involves constantly scanning the horizon for future risks and opportunities during calm seas. It contrasts sharply with a more reactive “we'll cross that bridge when we come to it” attitude. It's a philosophy of proactive vigilance, not anxious worrying.
• Related Values: This idiom champions the values of prudence (谨慎, jǐnshèn), foresight (远见, yuǎnjiàn), and long-term planning. It teaches that true security comes not from the absence of threats, but from the constant preparation for them.

• In Business: A CEO might use this in a speech to employees after a record-breaking quarter: “Our success is great, but we must 居安思危 and focus on innovation to stay ahead of the competition.” It's a common theme in corporate culture to prevent complacency.
• In Government and Politics: Leaders often quote this proverb when discussing national security, economic policy, or public health. A speech about the economy might state that despite stable growth, the nation must 居安思危 and address underlying structural issues.
• In Personal Life: A parent might advise their child who is excelling in school: “It's wonderful you're getting good grades, but you need to 居安思危. Keep working hard, because the exams will only get tougher.” It's advice to never get complacent with personal progress.
• Formality: This is a formal and respected Chengyu. It's used in written documents, speeches, news reports, and serious discussions. You would not typically use it in very casual, slangy conversation.

• Not Paranoia: The most common mistake for learners is to equate 居安思危 with pessimism, anxiety, or paranoia. This is incorrect. The mindset of 居安思危 is calm, rational, and strategic. It's about empowerment through preparation, not fear of the future. A paranoid person worries needlessly, while a person practicing 居安思危 plans methodically.
• Formality Mismatch: Using this formal Chengyu for trivial matters sounds awkward.
  • Incorrect: 天气预报说可能下雨，我要带伞，真是居安思危啊！(The forecast says it might rain, I should bring an umbrella, this is truly jū'ānsīwēi!)
  • Why it's wrong: This situation is too minor. Bringing an umbrella is simple common sense, not profound strategic foresight. It's like using a sledgehammer to crack a nut.
• “False Friend” Comparison: Don't confuse 居安思危 with being a “worrywart.” A worrywart is someone who is chronically anxious, often about things they cannot control. 居安思危 is the opposite; it focuses on analyzing potential, controllable risks and taking practical steps to mitigate them during a time of strength. It is a sign of wisdom, not anxiety.

• 未雨绸缪 (wèi yǔ chóu móu) - Lit: “To repair the house before it rains.” A very close synonym focusing on taking concrete preparatory actions.
• 防患于未然 (fáng huàn yú wèi rán) - To prevent a disaster before it occurs. Emphasizes the preventative aspect.
• 有备无患 (yǒu bèi wú huàn) - Where there is preparation, there is no disaster. A synonym that highlights the positive outcome of being prepared.
• 高枕无忧 (gāo zhěn wú yōu) - Lit: “To sleep on a high pillow without worries.” An antonym describing the dangerous state of complacency that 居安思危 warns against.
• 杞人忧天 (qǐ rén yōu tiān) - “The man of Qi who worried the sky would fall.” An important contrasting term. It describes groundless, irrational anxiety, the very opposite of the rational foresight of 居安思危.
• 临渴掘井 (lín kě jué jǐng) - “To dig a well when one is thirsty.” An antonym describing the foolishness of waiting until the last minute to solve a problem.
• 居危思安 (jū wēi sī ān) - To think of peace in times of danger. The logical inverse; to maintain hope and plan for a return to stability while in a crisis.
