危害

The Chinese term 危害 (wēihài) is a sophisticated verb and noun that translates most directly to 'harm,' 'endanger,' or 'jeopardize.' While English speakers might use 'harm' in almost any context, wēihài is typically reserved for more serious, systemic, or long-term negative impacts. It is a cornerstone of formal discourse, particularly in the realms of public health, environmental science, and legal terminology. When you use this word, you are not just talking about a minor scratch or a momentary inconvenience; you are discussing something that undermines the safety, stability, or well-being of an entity.

Core Concept

The word combines 危 (wēi), meaning danger or precariousness, with 害 (hài), meaning harm or damage. This combination suggests a harm that involves a significant element of risk or threat.

In daily life, you will encounter this word in warnings. For instance, a sign in a park might warn that certain behaviors wēihài the local ecosystem. In a medical context, a doctor might explain how high blood pressure wēihài one's long-term cardiovascular health. The word carries a weight of authority and gravity, making it a favorite for journalists and policymakers.

Structurally, wēihài is a transitive verb, meaning it directly takes an object. You do not need a preposition like 'to' in many cases where English would require one. For example, you 'wēihài health,' you don't 'wēihài to health.' However, in modern usage, you might occasionally see wēihài dào (危害到) to emphasize the reach or impact of the harm on a specific target.

Furthermore, the word is frequently used as a noun. In this form, it refers to the 'harm' or 'damage' itself. Phrases like 'the harm of plastic pollution' would use wēihài as the central noun. This dual nature makes it incredibly versatile in academic writing, where one might first describe an action that wēihài the public and then analyze the wēihài caused by that action.

Colloquial vs. Formal

While you might hear it in news broadcasts, it is rarely used for trivial matters. You wouldn't say a spicy pepper 'wēihài' your tongue; you would use 'shāng' (伤) or 'là' (辣) instead. Use 'wēihài' when the stakes are high.

To truly master this word, one must understand the cultural context of responsibility in China. The term is often used in social engineering and public service announcements to remind citizens of their duties toward the collective. Acts that wēihài social stability or national security are treated with the utmost seriousness in both language and law.

In summary, wēihài is more than just a synonym for 'hurt.' It is a word that carries the weight of consequence, the gravity of danger, and the formality of serious discussion. Whether you are taking an HSK exam, reading a Chinese newspaper, or discussing environmental issues, understanding the nuances of wēihài will significantly elevate your Chinese proficiency.

Using 危害 (wēihài) correctly requires an understanding of its grammatical flexibility and its specific semantic constraints. As a verb, its most common structure is [Subject] + [Adverb] + 危害 + [Object]. The object is almost always something abstract or a large-scale entity, such as 'health,' 'safety,' 'environment,' or 'interests.' You rarely use it with a specific person as the direct object in the way you would use 'hurt' (伤害 - shānghài).

Pattern 1: Direct Verb-Object

Structure: A 危害 B. Example: 污染危害环境 (Pollution harms the environment).

One of the most frequent adverbs paired with wēihài is 严重 (yánzhòng - seriously). Because the word itself implies a degree of severity, emphasizing that severity with yánzhòng is a standard practice in both spoken and written Chinese. You will often see this in health warnings, such as '吸烟严重危害健康' (Smoking seriously harms health).

Another common structure involves using wēihài as a noun, often following the verb 造成 (zàochéng - to cause). This is particularly common in academic or reporting contexts where the focus is on the result of an action. The pattern is [Subject] + 对 + [Target] + 造成 + [Adjective] + 危害. For example, '工厂对河流造成了严重的危害' (The factory caused serious harm to the river).

Pattern 2: Noun with '造成'

Structure: A 对 B 造成危害. This is the preferred way to describe the extent of the harm using modifiers like '巨大' (huge) or '不可逆' (irreversible).

When discussing potential threats, you might use the passive or potential forms. For instance, wēihài dào (危害到) suggests the harm is 'reaching' or 'affecting' a certain area. '这笔交易可能会危害到公司的声誉' (This deal might jeopardize the company's reputation). Here, the addition of 'dào' gives the verb a directional sense, implying the harm is spreading towards the target.

In formal writing, wēihài often appears in list formats or as part of a compound noun. For example, wēihài gònggòng āntián zhùyì (危害公共安全罪) is a specific legal category: 'Crime of Endangering Public Safety.' This demonstrates the word's role as a technical term. When you use it, you are aligning your speech with professional and legal standards.

Common Collocations

危害健康 (harm health), 危害安全 (endanger safety), 危害利益 (harm interests), 危害环境 (harm the environment), 危害社会 (harm society).

Lastly, consider the negative form. To say something does not cause harm, you would use bù wēihài or wú hài (无害). While wú hài is a separate adjective meaning 'harmless,' bù wēihài is used in specific denials of impact. '这种药不会危害胎儿' (This medicine will not harm the fetus). This usage is precise and reassuring in medical or scientific contexts.

If you were to turn on a Chinese news channel like CCTV, you would likely hear 危害 (wēihài) within the first fifteen minutes. It is a staple of the 'News Broadcast' (新闻联播) style of Mandarin. Journalists use it to describe everything from the 'harm' of international trade wars to the 'danger' posed by natural disasters. It provides a formal tone that suggests the reporter is discussing matters of national or global importance.

News & Media

Hear it in segments about: environmental protection, anti-corruption campaigns, and public health alerts (like during the COVID-19 pandemic).

In a corporate setting in China, particularly during safety training or compliance meetings, wēihài is used to discuss occupational hazards. A safety officer might list the wēihài of not wearing a helmet or the wēihài of improper chemical storage. In this context, it is often paired with 'shìbié' (识别 - to identify), as in '危害识别' (hazard identification).

Academic lectures, especially in the social sciences or medicine, are another prime location for this word. A sociology professor might discuss how income inequality wēihài social mobility. A medical professor will definitely use it when discussing 'pathological harm.' The word is essential for anyone looking to study in a Chinese university or engage in professional exchange.

You will also see wēihài on product packaging, particularly for items that carry health risks. Cigarette packs in China carry the warning '吸烟有害健康' (Smoking is harmful to health), which uses the related word yǒuhài, but the broader discussion in public health campaigns almost always uses wēihài to describe the long-term effects of tobacco.

Legal Documents

Contracts often include clauses about not performing actions that 'wēihài' the interests of the other party. In criminal law, it defines the threshold of impact required for a crime to be prosecuted.

Finally, in the digital age, wēihài is frequently used in discussions about network security. Cyberattacks are said to wēihài data privacy and national information infrastructure. If you are reading tech blogs in Chinese, you'll see it used to describe the 'harm' of viruses, malware, and data breaches.

In summary, wēihài is everywhere that serious consequences are discussed. It is the language of the expert, the official, and the concerned citizen. Understanding where it appears helps you gauge the 'temperature' of a conversation; if wēihài is being used, the situation is likely serious.

One of the most common mistakes English speakers make is using 危害 (wēihài) for minor, personal injuries. If you accidentally step on someone's foot, you have not 'wēihài-ed' them. For physical pain or minor injury to a person, you should use 弄疼 (nòngténg - to hurt) or 伤害 (shānghài - to injure/harm). Wēihài is too 'big' for small personal accidents.

Mistake 1: Misusing Register

Using 'wēihài' for trivial things like 'This spicy food harms my stomach' (wrong) vs. 'Chronic stress harms your health' (correct).

Another frequent error is confusing wēihài with 损害 (sǔnhài). While they both mean 'harm' or 'damage,' sǔnhài is more often used for property, reputation, or economic interests. You 'sǔnhài' a car or a company's image, but you 'wēihài' the safety of the passengers or the stability of the market. Wēihài has a stronger sense of 'endangering' the future or the system.

Learners also struggle with the word order. Because wēihài can be both a verb and a noun, students sometimes use it incorrectly in a sentence. Remember that as a verb, it directly precedes the object. As a noun, it often follows '造成' (zàochéng). A common mistake is saying '对健康有危害' (has harm to health) instead of the more natural '危害健康' or '对健康有害' (is harmful to health).

Confusing wēihài with 危险 (wēixiǎn) is also common. Wēixiǎn is an adjective meaning 'dangerous.' You can say 'This place is dangerous' (这里很危险), but you cannot say 'This place is wēihài.' Wēihài requires an action or a result of harm. You could say 'The pollution here wēihài-s the residents' health.'

Mistake 2: Part of Speech

Mistaking 'wēihài' (verb/noun) for 'wēixiǎn' (adjective). You can't say 'This is very wēihài.'

Finally, watch out for the nuance between wēihài and 破坏 (pòhuài). Pòhuài means 'to destroy' or 'to break' (like rules or a physical object). While a pòhuài action can wēihài something, they are not interchangeable. Pòhuài is the act of destruction; wēihài is the resulting state of harm or the threat posed to the target's well-being.

By being mindful of these distinctions—scale of harm, part of speech, and specific collocations—you can avoid the common pitfalls that mark a learner's speech and instead communicate with the precision of a native speaker.

To truly master the concept of 'harm' in Chinese, you must understand where 危害 (wēihài) sits in relation to its synonyms. Each word has a specific flavor and context. Choosing the right one is the difference between sounding like a beginner and sounding like a scholar.

危害 vs. 损害 (sǔnhài)

危害: Focuses on health, safety, and systemic danger. (e.g., 危害生命 - endanger life).
损害: Focuses on property, economy, and abstract values like reputation. (e.g., 损害利益 - damage interests).

伤害 (shānghài) is perhaps the most common alternative. It is the general word for 'to hurt' or 'to injure.' Unlike wēihài, shānghài is frequently used for emotional pain or physical injury to an individual. You would say 'You hurt my feelings' (你伤害了我的感情) using shānghài, but never wēihài.

Another important relative is 危及 (wēijí). This word is even more urgent than wēihài. It means 'to threaten' or 'to critically endanger.' It is almost always used with life-or-death situations. For example, '危及生命' (to threaten one's life). If wēihài is 'harming,' wēijí is 'putting at immediate risk.'

危害 vs. 危及 (wēijí)

危害: General serious harm (e.g., chronic smoking).
危及: Immediate, critical danger (e.g., a building on fire).

破坏 (pòhuài), as mentioned before, focuses on the act of breaking or destroying. If you 'pòhuài' a system, the result is that you 'wēihài' its safety. Use pòhuài when you want to emphasize the aggressive act of destruction, and wēihài when you want to emphasize the resulting threat or harm.

For an even more formal or literary touch, you might see 妨碍 (fáng'ài). This means 'to hinder' or 'to impede.' While not as strong as 'harm,' it is used in contexts where something is getting in the way of progress or safety. For example, '妨碍交通' (to obstruct traffic). This is a 'lighter' alternative when 'harm' is too strong a word.

Word Comparison Table

• 危害 (wēihài): Serious, systemic harm (Health, Safety).
• 损害 (sǔnhài): Damage to value (Reputation, Economy).
• 伤害 (shānghài): Personal hurt (Physical, Emotional).
• 破坏 (pòhuài): Active destruction (Environment, Rules).
• 危及 (wēijí): Immediate threat (Life, Existence).

In conclusion, while these words overlap, their 'territories' are distinct. By learning the specific targets each verb typically 'attacks' (health for wēihài, interests for sǔnhài, feelings for shānghài), you can choose your words with precision and authority.
