• Summary: “Zìláishuǐ” (自来水) is the Chinese word for “tap water” or “running water.” Literally meaning “self-come-water,” it refers to the water supplied to homes and buildings through pipes. While it's a basic utility term, understanding its cultural context—specifically that it's generally not considered safe to drink without boiling—is crucial for anyone living in or visiting China. This page also explores its modern slang usage to describe passionate, unpaid fans of media or products.

• Pinyin (with tone marks): zì lái shuǐ
• Part of Speech: Noun
• HSK Level: HSK 3
• Concise Definition: Water supplied through pipes to a building; tap water.
• In a Nutshell: Zìláishuǐ is the everyday word for the water that comes out of your faucet. Its name perfectly describes its function: it's the water that “comes by itself,” contrasting with the old-fashioned way of fetching water from a well or river. It's a fundamental concept for discussing daily life, from cooking and cleaning to public utilities and health.

• 自 (zì): A common character meaning “self,” “from,” or “naturally.” Here, it implies that the water's arrival is automatic or happens on its own.
• 来 (lái): The verb “to come” or “to arrive.” It signifies the movement of the water to the user.
• 水 (shuǐ): The character for “water.”

The characters combine with perfect, logical simplicity: 自 (zì) + 来 (lái) + 水 (shuǐ) = “self-coming water.” This paints a clear picture of water that flows effortlessly from a source directly to you, a symbol of modern convenience.

The concept of `自来水` is more than just a utility; it's a symbol of modernization and public health in China. For centuries, access to water meant digging wells or living near rivers. The widespread implementation of piped `自来水` represented a huge leap in quality of life and sanitation. However, there's a crucial difference in cultural practice compared to many Western countries.

• Western Concept: “Tap water” is generally assumed to be potable (safe to drink directly from the tap).
• Chinese Concept: `自来水` is primarily seen as utility water for washing, cleaning, and flushing. It is almost never consumed directly. The universal practice, ingrained from a young age, is to boil tap water (`烧开水 shāo kāishuǐ`) to kill bacteria and impurities before drinking it.

This cultural habit stems from historical and ongoing concerns about water quality. While the water in major cities is treated, the infrastructure can be old, and public trust in its potability remains low. Therefore, asking for “tap water” in a restaurant in China will likely result in confusion or a glass of boiled water (`开水 kāishuǐ`), either hot or cooled. This highlights a key cultural value: a deep-seated emphasis on health, safety, and the precaution of “better safe than sorry.”

`自来水` is a high-frequency word used in many everyday contexts.

It's used when talking about any household activity involving water from the faucet, like cooking, bathing, or cleaning.

• “Please use tap water to wash the vegetables.” (请用自来水洗菜。)

This is the most important context for learners. Conversations often revolve around whether the water is safe and the necessity of boiling it.

• “You can't drink the tap water directly.” (这个自来水不能直接喝。)

It's used when discussing water bills (`水费 shuǐfèi`) or when the water supply is cut off (`停水 tíngshuǐ`).

• “The tap water was cut off again this afternoon.” (今天下午又停自来水了。)

On the internet, `自来水` has developed a popular slang meaning: a spontaneous, unpaid fan. These are people who love a movie, TV show, or product so much that they promote it to everyone they know “naturally,” like water flowing from a tap, without being paid by the production company. Someone who does this is called a member of the “spontaneous water army” (`自来水军 zìláishuǐjūn`).

  • English: This area doesn't have running water yet; everyone still uses well water.

  • English: I'm not a paid promoter they hired; I'm a real “spontaneous fan”!
  • Analysis: This is a perfect example of the modern slang usage. It contrasts the paid “water army” (`水军 shuǐjūn`) with the genuine, unpaid fan (`自来水`).

  • Analysis: Shows the slang term used in a more formal analysis, such as in a news article or review.

• The Potability Pitfall: The most common and critical mistake for foreigners is assuming `自来水` is safe to drink. Never drink tap water in China without boiling it first. When you want drinking water, ask for `开水 (kāishuǐ)` (boiled water) or `矿泉水 (kuàngquánshuǐ)` (mineral water).
• False Friend: “Tap Water”: While “tap water” is the direct translation, the cultural assumption of drinkability doesn't carry over. Thinking of `自来水` as “utility water” is a safer mental model.
• Incorrect Usage Example:
  • (Incorrect) 我在河里取了一些自来水。
  • Pinyin: Wǒ zài hé lǐ qǔ le yīxiē zìláishuǐ.
  • (Intended) I got some tap water from the river.
  • Why it's wrong: This is a logical contradiction. `自来水` by definition comes from pipes and a municipal system. Water from a river is `河水 (héshuǐ)`. The name specifies the source and delivery method.

• 开水 (kāishuǐ) - Boiled water. The safe-to-drink version of `自来水`.
• 矿泉水 (kuàngquánshuǐ) - Mineral water. A common alternative to boiling tap water for drinking.

• 停水 (tíngshuǐ) - To have a water outage. The verb for when the `自来水` stops.
• 水费 (shuǐfèi) - Water bill/fee. The cost associated with using `自来水`.
