• Summary: A popular and vivid Chinese internet slang term, 踩雷 (cǎiléi) literally translates to “step on a landmine.” Metaphorically, it's used to describe the frustrating experience of making a bad choice that leads to a surprisingly negative outcome. Whether it's buying a low-quality product online, trying a terrible restaurant, or watching a hyped-up movie that turns out to be awful, to “cǎiléi” is to encounter an unexpected disaster you wish you had avoided. This term is central to modern Chinese consumer and internet culture.

• Pinyin (with tone marks): cǎi léi
• Part of Speech: Verb Phrase (Verb-Object)
• HSK Level: N/A (Modern Slang)
• Concise Definition: To encounter an unexpectedly bad product, service, or experience.
• In a Nutshell: Imagine you're navigating the vast world of online shopping, new restaurants, or movie releases. You make a choice, expecting it to be good, or at least okay. Instead, it's a total disaster. That feeling of sudden, explosive disappointment is perfectly captured by 踩雷 (cǎiléi). It’s the “boom” moment when you realize you've made a terrible mistake. It's the opposite of discovering a hidden gem.

• 踩 (cǎi): To step on, tread, or trample. Think of your foot stepping down on something.
• 雷 (léi): While this character's primary meaning is “thunder,” in a military or gaming context (like in 地雷 dìléi), it means “mine” or “explosive.”
• How they combine: Putting “step on” (踩) and “mine” (雷) together creates a powerful and modern metaphor. It paints a picture of walking into a hidden trap that “explodes” with disappointment. The choice seemed safe, but it led to a negative surprise.

The rise of 踩雷 (cǎiléi) is directly tied to the explosion of e-commerce and social media in China. In a marketplace with endless choices, from makeup brands to vacation spots, consumers rely heavily on shared experiences to make decisions. Sharing your “cǎiléi” story online is a common, almost communal, activity. It serves as a warning to others, helping them “avoid the mines” (避雷, bìléi). This contrasts with Western concepts like “it was a bust” or “I got ripped off.” While the meaning is similar, 踩雷 (cǎiléi) is part of a larger ecosystem of slang. Its direct opposite, 种草 (zhòngcǎo)—“to plant grass” (i.e., to make someone want something)—and related terms like 避雷 (bìléi)—“to avoid the mine”—create a whole vocabulary for navigating consumer culture. This reflects a more collectivist approach to information sharing, where individuals actively help the community make better choices. The metaphor is more active and visual than its English counterparts.

踩雷 (cǎiléi) is highly informal and is used constantly in daily conversation and online, especially on platforms like Xiaohongshu (小红书), Weibo (微博), and Douyin (抖音).

• Online Shopping and Product Reviews: This is the most common usage. A user will buy a product based on good advertising but find it to be of poor quality. They will then post a review saying, “兄弟姐妹们，我踩雷了！” (Brothers and sisters, I stepped on a landmine!).
• Restaurants and Food: Trying a new, highly-rated restaurant only to have a terrible meal is a classic 踩雷 situation.
• Entertainment: Watching a movie or TV series with great trailers and posters that turns out to be boring or poorly made.
• Travel: Booking a hotel that looks beautiful in photos but is dirty and unpleasant in reality.
• Investments: In financial slang, buying a stock that suddenly plummets can also be described as 踩雷.

The connotation is always negative, expressing disappointment, frustration, and a sense of being let down.

• Example 1:
  • 我新买的这个吸尘器，噪音又大又吸不干净，真是踩雷了。
  • Pinyin: Wǒ xīn mǎi de zhège xīchénqì, zàoyīn yòu dà yòu xī bù gānjìng, zhēnshi cǎiléi le.
  • English: This new vacuum cleaner I bought is noisy and doesn't clean well. I really made a bad choice.
  • Analysis: A classic example of 踩雷 in the context of a disappointing product purchase. The particle “了 (le)” indicates the action has been completed.
• Example 2:
  • 这家网红餐厅排队两小时，结果味道很一般，感觉踩雷了。
  • Pinyin: Zhè jiā wǎnghóng cāntīng páiduì liǎng xiǎoshí, jiéguǒ wèidào hěn yībān, gǎnjué cǎiléi le.
  • English: I waited in line for two hours at this internet-famous restaurant, but the food was just so-so. I feel like it was a total dud.
  • Analysis: Here, “感觉 (gǎnjué)” means “to feel like,” softening the statement slightly but still conveying clear disappointment with a hyped-up experience.
• Example 3:
  • 出去玩之前，最好先看看攻略，免得踩雷。
  • Pinyin: Chūqù wán zhīqián, zuìhǎo xiān kànkan gōnglüè, miǎnde cǎiléi.
  • English: Before you go travel, it's best to read some guides first to avoid any disasters.
  • Analysis: This sentence uses 踩雷 as a potential negative outcome to be avoided. “免得 (miǎnde)” means “so as to avoid.”
• Example 4:
  • 听说这部电影的结尾特别烂，谁看谁踩雷。
  • Pinyin: Tīngshuō zhè bù diànyǐng de jiéwěi tèbié làn, shéi kàn shéi cǎiléi.
  • English: I heard the ending of this movie is terrible. Whoever watches it is in for a disappointment.
  • Analysis: The structure “谁…谁…” (shéi…shéi…) means “whoever…”. It's a strong, informal way to warn everyone away from a bad experience.
• Example 5:
  • 我看推荐买的这个粉底液，色号完全不对，又踩雷了。
  • Pinyin: Wǒ kàn tuījiàn mǎi de zhège fěndǐyè, sèhào wánquán bùduì, yòu cǎiléi le.
  • English: I bought this foundation based on a recommendation, but the shade is completely wrong. I've hit a dud again.
  • Analysis: “又 (yòu)” means “again,” implying this isn't the first time the speaker has had a bad shopping experience. This is a very common scenario for makeup purchases.
• Example 6:
  • 帮我看看这些酒店哪个好？我怕自己选会踩雷。
  • Pinyin: Bāng wǒ kànkan zhèxiē jiǔdiàn nǎge hǎo? Wǒ pà zìjǐ xuǎn huì cǎiléi.
  • English: Can you help me see which of these hotels is good? I'm afraid I'll make a bad choice if I pick one myself.
  • Analysis: This shows how people proactively try to avoid 踩雷 by seeking advice from others.
• Example 7:
  • 他去年投资踩雷了，亏了不少钱。
  • Pinyin: Tā qùnián tóuzī cǎiléi le, kuī le bùshǎo qián.
  • English: He made a bad investment last year and lost quite a bit of money.
  • Analysis: This demonstrates the use of 踩雷 in a financial context, referring to a stock or investment that performed disastrously.
• Example 8:
  • 这本书的封面设计得很好看，内容却很空洞，让我大踩雷。
  • Pinyin: Zhè běn shū de fēngmiàn shèjì de hěn hǎokàn, nèiróng què hěn kōngdòng, ràng wǒ dà cǎiléi.
  • English: The cover design of this book is beautiful, but the content is very empty. It was a huge disappointment for me.
  • Analysis: Adding “大 (dà)” before 踩雷 emphasizes that it was a *major* disappointment, not a minor one.
• Example 9:
  • 我朋友推荐的理发师把我头发剪坏了，这次算是被他坑到踩雷了。
  • Pinyin: Wǒ péngyou tuījiàn de lǐfàshī bǎ wǒ tóufa jiǎn huài le, zhè cì suànshì bèi tā kēng dào cǎiléi le.
  • English: The hairstylist my friend recommended ruined my hair. This time, I really got burned by his suggestion.
  • Analysis: This example connects 踩雷 with being “坑 (kēng),” which means to be ripped off or fall into a trap. It shows how these slang terms can be used together.
• Example 10:
  • 这次购物节我买的东西都很好，一个雷都没踩。
  • Pinyin: Zhè cì gòuwùjié wǒ mǎi de dōngxi dōu hěn hǎo, yī ge léi dōu méi cǎi.
  • English: Everything I bought during this shopping festival was great; I didn't get a single dud.
  • Analysis: This is a negative sentence structure, splitting the verb-object phrase. “一个雷都没踩” (yī ge léi dōu méi cǎi) literally means “didn't step on a single mine.” It's a common way to express a successful shopping experience.

• Not for Serious Tragedies: A crucial mistake is to use 踩雷 for genuinely serious or tragic events. It's for consumer disappointments, bad meals, or boring movies—not car accidents, illnesses, or other life-altering misfortunes. The “landmine” is purely a metaphor for a bad choice or product.
• Informal Use Only: This is slang. Do not use it in formal, academic, or professional writing. It belongs in text messages, social media posts, and casual conversations with friends. Using it in a business presentation would be highly unprofessional.
• “踩雷” vs. “犯错 (fàncuò)”: Don't confuse 踩雷 with the general term for “making a mistake,” which is 犯错 (fàncuò).
  • 犯错 (fàncuò) is about a procedural or moral error. Example: Forgetting to do your homework is a 犯错.
  • 踩雷 (cǎiléi) is about a *choice* that results in an unexpectedly bad *outcome*. Example: Choosing to eat at a restaurant that gives you bad food is a 踩雷. The focus is on the disappointing result of your selection.

• 种草 (zhòngcǎo) - The direct antonym. Literally “to plant grass,” it means to be tempted or inspired by someone's recommendation to want to buy or try something.
• 避雷 (bìléi) - “To avoid the mine.” The act of successfully dodging a bad product or experience, often because you read a negative review (a 踩雷 post).
• 排雷 (páiléi) - “To clear the mines.” Describes a person (like a reviewer or influencer) who tries out many products to discover and report which ones are good and which ones are bad (the “mines”).
• 拔草 (bácǎo) - “To pull up grass.” This has two common meanings: 1) To finally buy something you've been wanting for a long time (from being 种草). 2) To lose interest in a product you previously wanted, often after seeing a negative review.
• 坑 (kēng) - “A pit” or “a trap.” A very popular slang term for anything that is a rip-off, a scam, or a situation that's much worse than it appeared. It's a close synonym for the outcome of 踩雷.
• 翻车 (fānchē) - “To flip over the car.” Refers to a plan or effort that goes spectacularly wrong, a public failure. Often used for failed publicity stunts or when a trusted influencer recommends a bad product.
• 安利 (ānlì) - Named after the brand Amway. Slang for enthusiastically, almost obsessively, recommending a product, TV show, or hobby to someone. A more intense form of 种草.
