What is 危险 (wēi xiǎn)?
危险 (wēi xiǎn) literally breaks down into two characters: 危 (wēi) meaning “dangerous” or “perilous,” and 险 (xiǎn) meaning “risk” or “hazard.” Together, they form the standard word for “danger” in Mandarin Chinese. This is the word you’ll see on every construction site barrier, every electrical warning sticker, and every severe weather alert across mainland China.
In everyday conversation, 危险 functions as both an adjective and a noun. As an adjective, you might say 这条路很危险 (zhè tiáo lù hěn wēi xiǎn) – “this road is very dangerous.” As a noun, you could say 有危险 (yǒu wēi xiǎn) – “there is danger.” The flexibility makes it one of the most useful safety-related words in your Chinese vocabulary.

Pronunciation Guide for 危险 (wēi xiǎn)
Getting the tones right on 危险 (wēi xiǎn) matters because it changes the meaning if you get it wrong. Here’s the breakdown:
- 危 (wēi) – First tone (high, flat). Think of it as a steady, unchanging pitch. It sounds like the English word “way” but held at a constant high note.
- 险 (xiǎn) – Third tone (dipping, then rising). This tone starts mid-low, dips down, then rises slightly. It takes practice because third tone words can sound almost like they’re being swallowed before they rise again.
When you say 危险 (wēi xiǎn) in natural speech, the third tone on 险 often changes. In a two-syllable word where the second syllable is third tone, it sometimes becomes a “half third tone” – dipping but not fully rising. This is one of the trickier aspects of Mandarin pronunciation, and even intermediate learners struggle with it. For a detailed breakdown of tone rules and pronunciation strategies, Hacking Chinese offers excellent resources on mastering Mandarin tones.
A useful memory trick: 危 (wēi) with its high, flat first tone sounds like an alarm going off – steady and urgent. 险 (xiǎn) with its dipping third tone sounds like someone catching their breath before rising again. Together, they create the sound of a warning: urgent, then cautious.
Practical Usage and Common Scenarios
Daily Scenarios Where You’ll Use 危险 (wēi xiǎn)
Here are the real-world situations where you’ll actually need to know how to say danger in Chinese:
- Construction zones: Red banners with 危险 (wēi xiǎn) and 禁止进入 (jìn zhǐ jìn rù, “no entry”) are everywhere in Chinese cities. The rapid development means new construction pops up overnight, and those barriers are serious – they’re not suggestions.
- Weather warnings: During summer typhoon season, your phone will buzz with emergency alerts featuring 危险 (wēi xiǎn). Understanding these warnings can literally save your life when severe weather hits.
- Traffic situations: If you’re taking a taxi in China and the driver is going too fast, you might say 很危险 (hěn wēi xiǎn) to get them to slow down. It’s direct but not rude – a safety concern everyone understands.
- Electrical hazards: Every apartment has warning stickers near electrical panels. The characters 危险 (wēi xiǎn) in a red triangle are the universal symbol for “don’t touch this.”
- Warning friends: If you’re out exploring and notice a crumbling sidewalk or an unlit staircase, saying 小心, 很危险 (xiǎo xīn, hěn wēi xiǎn) is the natural way to warn your companions.
Reading Safety Signs in China
Chinese safety signs follow a consistent pattern that becomes easy to recognize once you know what to look for. The most common format is:
- Red triangle with black symbol – Warning signs (危险, 小心)
- Red circle with white background – Prohibition signs (禁止, jìn zhǐ = “forbidden”)
- Blue circle with white symbol – Mandatory signs (必须, bì xū = “must”)
The word 危险 (wēi xiǎn) almost always appears on red warning signs. If you see a red background with white characters, that’s an immediate danger warning – something that could cause injury or death if ignored. Yellow signs with black text are cautionary warnings, less severe but still worth your attention.

Cultural Context and Regional Variations
The concept of danger in Chinese culture carries some nuances that differ from Western perspectives. In China, there’s a stronger cultural emphasis on collective safety over individual risk-taking. Warning signs are often more explicit and direct than in some Western countries, reflecting a societal expectation that authorities should clearly mark hazards.
For insights into how modern Chinese culture approaches safety, risk, and public warnings, Sixth Tone publishes excellent articles on contemporary Chinese life, including how urban development and safety regulations affect daily experiences. Their coverage of Chinese cities offers context for why you’ll see so many 危险 signs in rapidly developing areas.
Regional variations in danger warnings are minimal across mainland China – the standard 危险 (wēi xiǎn) is universal. However, in Hong Kong, you might see bilingual signs with “DANGER” alongside 危险 due to the city’s bilingual legal requirements. In Taiwan, the same characters are used but sometimes with traditional character variations in other contexts. For mainland Mandarin learners, 危险 is the only word you need.
One cultural note: Chinese people often use 危险 (wēi xiǎn) more broadly than English speakers use “danger.” In Chinese, describing something as 危险 can mean anything from “literally life-threatening” to “risky but worth trying” depending on context and tone. A friend might describe a spicy hot pot as 很危险 (hěn wēi xiǎn) with a grin, meaning it’s dangerously delicious, not actually unsafe.
Common Mistakes to Avoid
When learning how to say danger in Chinese, watch out for these common errors:
- Don’t confuse 危险 with 冒险 (mào xiǎn): 冒险 means “to take a risk” or “adventure” – it’s something you choose to do. 危险 is the risk itself, not the act of taking it. Saying 我很冒险 (wǒ hěn mào xiǎn) to mean “I’m in danger” is incorrect; use 我很危险 (wǒ hěn wēi xiǎn) instead.
- Don’t forget the tone on 险 (xiǎn): Pronouncing it with a second tone (xián) changes the meaning entirely and makes the word hard for native speakers to understand. Practice the dipping third tone until it feels natural.
- Don’t use 危险 for minor inconveniences: Spilling coffee or missing a bus isn’t 危险. Reserve this word for actual safety hazards. For minor problems, use 麻烦 (má fan, “troublesome”) or 倒霉 (dǎo méi, “unlucky”).
- Don’t translate “dangerous” word-for-word: In English, we might say “that’s a dangerous person” to mean someone is risky to associate with. In Chinese, 危险的人 (wēi xiǎn de rén) literally means someone who poses a physical threat – not the same social connotation.

Frequently Asked Questions
Common Questions About 危险 (wēi xiǎn)
Is 危险 (wēi xiǎn) the only way to say danger in Chinese?
危险 (wēi xiǎn) is the standard and most common way to say “danger” in Mandarin Chinese. For everyday warnings and safety signs, it’s the word you’ll see and use. In more literary or formal contexts, you might encounter 危害 (wēi hài, “harm”) or 风险 (fēng xiǎn, “risk”), but 危险 is universally understood and appropriate for all situations.
How do you say “it’s dangerous” in Chinese?
The most natural way to say “it’s dangerous” is 很危险 (hěn wēi xiǎn), which literally means “very dangerous.” Chinese speakers often use 很 (hěn) as a general intensifier, so even for moderate danger, 很危险 is the standard phrase. For a more formal warning, you can say 有危险 (yǒu wēi xiǎn), meaning “there is danger.”
What’s the difference between 危险 (wēi xiǎn) and 安全 (ān quán)?
危险 (wēi xiǎn) means “danger” or “dangerous,” while 安全 (ān quán) means “safe” or “safety.” They are direct opposites. You’ll often see them paired on signs: 危险区域 (wēi xiǎn qū yù, “danger zone”) versus 安全出口 (ān quán chū kǒu, “safety exit”). Learning both words together helps you navigate any safety situation in China.
Can I use 危险 to describe people?
Yes, but with caution. 危险的人 (wēi xiǎn de rén) means a dangerous person who poses a physical threat. However, it doesn’t carry the same broad meaning as in English (where “dangerous person” might mean someone risky to date or associate with). In Chinese, it’s literal – someone who is physically dangerous. For social or emotional risks, Chinese uses different expressions entirely.
Where will I see 危险 signs in China?
You’ll encounter 危险 signs constantly in China: construction sites, electrical panels, road work zones, steep hiking trails, factory areas, and severe weather warnings. Anywhere there’s a genuine physical hazard, the red 危险 sign will appear. Learning to recognize this character is one of the most practical safety skills for life in China.
How do I warn someone about danger in Chinese politely?
For polite warnings, use 小心 (xiǎo xīn, “be careful”) rather than directly saying 危险. 小心 is softer and more caring – like saying “watch out” to a friend. If the situation is genuinely urgent, 危险 combined with 小心 creates a natural warning: 小心, 前面很危险 (xiǎo xīn, qián miàn hěn wēi xiǎn) – “Be careful, it’s very dangerous up ahead.”
