• Pinyin (with tone marks): yùfáng
• Part of Speech: Verb
• HSK Level: HSK 4
• Concise Definition: To take measures in advance to guard against or stop something undesirable from happening.
• In a Nutshell: 预防 (yùfáng) is all about proactive defense. It’s not just “stopping” something; it’s about preparing and building a shield *before* the problem even appears. Think of it as the action of “prevention” that you see in phrases like “disease prevention” or “fire prevention.” It carries a sense of foresight, planning, and responsibility.

• 预 (yù): This character means “in advance” or “to prepare.” It's composed of 予 (yú), meaning “to give,” and 页 (yè), which means “head.” You can think of it as using your head (页) to think things through in advance (预). It's a key component in words related to forecasting and pre-planning, like 预报 (yùbào, forecast) and 预订 (yùdìng, to reserve).
• 防 (fáng): This character means “to defend” or “to guard against.” The radical on the left, 阝(fù), is a variant of 阜, which originally depicted a mound or hill, often associated with city walls and defenses. The right part, 方 (fāng), acts as the phonetic component. So, 防 (fáng) is fundamentally about setting up a defense (阝) to protect a place.
• Together, 预防 (yùfáng) literally means “to prepare in advance” (预) “to defend against” (防). The meaning is incredibly direct: taking proactive measures to guard against a negative outcome.

The concept of 预防 (yùfáng) is deeply embedded in Chinese culture, extending far beyond a simple dictionary definition. It aligns with the high cultural value placed on foresight, stability, and collective well-being. Its most significant application is in health. Traditional Chinese Medicine (TCM) is built upon the principle of 治未病 (zhì wèi bìng) — literally “to treat the illness that is not yet an illness.” This philosophy emphasizes maintaining balance in the body through diet, exercise, and lifestyle to 预防 (yùfáng) sickness before it ever takes root. This contrasts with a Western model that has historically been more focused on “curing” diseases after they manifest. While Western medicine now heavily promotes prevention, the idea has been a cornerstone of Chinese health philosophy for centuries. This extends to societal governance as well. Chinese proverbs and government policies often stress the importance of nipping problems in the bud (防患于未然 - fáng huàn yú wèi rán) to maintain social harmony and stability. Therefore, when you hear 预防 (yùfáng), you're tapping into a cultural mindset that believes the wisest course of action is always to prepare for the worst, rather than reacting to it.

预防 (yùfáng) is a standard, somewhat formal term used widely in official announcements, news reports, healthcare, and educated conversation. You won't typically hear it in very casual slang, but it's essential for discussing almost any topic related to health, safety, or risk.

A common pitfall for English speakers is using 预防 (yùfáng) to mean “stop someone from doing something.” While “prevent” can have this meaning in English, 预防 (yùfáng) is almost exclusively used for preventing an *event* or *undesirable state* (like a disease, fire, or crisis), not stopping a person's immediate action.

• Incorrect: 我预防他离开。 (Wǒ yùfáng tā líkāi.)
  • This sounds very strange, as if you are taking long-term medical precautions against his departure.
• Correct: 我阻止他离开。 (Wǒ zǔzhǐ tā líkāi.)
  • 阻止 (zǔzhǐ) means “to stop” or “to block” someone's action. This is the correct word here.

预防 (yùfáng) vs. 避免 (bìmiǎn) vs. 防止 (fángzhǐ):

• 预防 (yùfáng): Proactive preparation and defense against a potential future problem. (e.g., vaccination).
• 避免 (bìmiǎn): To *avoid* or *steer clear of* something. It's about evading a situation, not building a defense. You 避免 (bìmiǎn) a traffic jam by taking another road; you don't 预防 (yùfáng) it.
• 防止 (fángzhǐ): To prevent or stop something from happening, often something more immediate or a process already underway. It overlaps with 预防 but can be stronger and more direct. You might use 防止 (fángzhǐ) to stop a leak from getting worse, whereas you'd use 预防 (yùfáng) to do maintenance to ensure leaks don't happen in the first place.

• 措施 (cuòshī) - Measure, step. The actions you take to 预防 something. 预防措施 (yùfáng cuòshī) means “preventative measures.”
• 防止 (fángzhǐ) - To prevent, to stop. A close synonym, but often used for more immediate threats.
• 避免 (bìmiǎn) - To avoid. Focuses on steering clear of a problem rather than building a defense against it.
• 保护 (bǎohù) - To protect. Broader than 预防. You protect something you already have; you 预防 something bad that might happen to it in the future.
• 疫苗 (yìmiáo) - Vaccine. One of the most common tools for 预防 disease.
• 安全 (ānquán) - Safety, security. The goal state that is achieved through effective 预防.
• 风险 (fēngxiǎn) - Risk. The abstract danger or potential problem that you want to 预防.
• 治未病 (zhì wèi bìng) - “Treating the illness that is not yet an illness.” The core Traditional Chinese Medicine philosophy that underpins the cultural importance of 预防.
