• Keywords: fùrújiēzhī, 妇孺皆知, Chinese idiom for common knowledge, what does 妇孺皆知 mean, widely known in Chinese, Chinese chengyu, known to all, household name in Chinese, even women and children know
• Summary: The Chinese idiom 妇孺皆知 (fùrújiēzhī) literally means “known by women and children,” and is used to describe a fact, story, or person that is so famous it has become common knowledge. It's the equivalent of saying something is a “household name” in English. This page explores the meaning, cultural origins, and practical modern usage of this essential Chinese chengyu, providing clear examples for learners.

• Pinyin (with tone marks): fù rú jiē zhī
• Part of Speech: Idiom (Chengyu), Adjective
• HSK Level: N/A
• Concise Definition: Known to everyone; so widely known that even women and children are aware of it.
• In a Nutshell: Imagine something so famous that it has seeped into every corner of society. That's the feeling of 妇孺皆知. The idiom literally says “women (妇) and children (孺) all (皆) know (知) it.” This paints a powerful picture of total saturation. In ancient China, women and children were often considered the least informed members of society, so if even *they* knew something, it was truly undeniable common knowledge.

• 妇 (fù): Refers to a married woman or woman in general.
• 孺 (rú): Refers to a child or an infant.
• 皆 (jiē): A more formal or literary character meaning “all” or “everybody,” similar to 都 (dōu).
• 知 (zhī): Means “to know” or “to be aware of.”

The characters combine literally and powerfully: “Women and children all know.” The choice of “women and children” is not random; it is a deliberate rhetorical device to emphasize the absolute ubiquity of the information. It's not just known by scholars or officials—it's known by everyone, without exception.

• Historical Lens: This idiom is a small window into the social structure of ancient China. By singling out “women and children” as the benchmark for widespread knowledge, it reflects a time when they were typically less involved in public life and formal education. The phrase's power comes from this implicit social hierarchy: if news or a story has reached even the most peripheral members of society, its spread is complete.
• Comparison to Western Concepts: In English, we might say “it's common knowledge,” “it's a household name,” or “everyone and their mother knows.” While similar, 妇孺皆知 has a more descriptive and vivid origin. “Household name” focuses on the family unit, while 妇孺皆知 paints a broader societal picture, emphasizing demographics (gender and age). It highlights the idea of a shared cultural consciousness, where certain stories, heroes, and facts are so foundational that they belong to everyone, regardless of their station in life.

妇孺皆知 is still a very common and useful idiom in modern Mandarin. It is used in both formal contexts (news, literature) and everyday conversation.

• Describing People: It's often used to talk about celebrities, historical figures, or national heroes whose fame is undeniable.
• Describing Stories/Facts: It can describe classic novels (like *Journey to the West*), famous legends, historical events, or even basic scientific facts.
• Connotation: The term is generally neutral, simply stating the fact of something being widely known. However, it can sometimes be used with a tone of surprise or mild exasperation, as in, “How can you not know that? It's 妇孺皆知!”

• Example 1:
  • 孙悟空这个名字在中国是妇孺皆知的。
  • Pinyin: Sūn Wùkōng zhège míngzì zài Zhōngguó shì fù rú jiē zhī de.
  • English: The name “Sun Wukong” (the Monkey King) is known to everyone in China.
  • Analysis: This is a classic use case, referring to a legendary character that every Chinese person grows up hearing about.
• Example 2:
  • 他的英雄事迹已经变得妇孺皆知。
  • Pinyin: Tā de yīngxióng shìjì yǐjīng biànde fù rú jiē zhī.

  • Pinyin: Dàjiā dōu yǐwéi zhè shì fù rú jiē zhī de chángshí, méi xiǎngdào hái yǒu rén bù zhīdào.
  • English: Everyone thought this was common knowledge that even women and children would know, but surprisingly, some people still didn't know.
  • Analysis: This sentence uses the idiom to express surprise that someone is unaware of a very basic fact (常识, chángshí).
• Example 4:
  • 华为这个品牌不仅在中国，在世界上许多地方也几乎是妇孺皆知。
  • Pinyin: Huáwéi zhège pǐnpái bùjǐn zài Zhōngguó, zài shìjiè shàng xǔduō dìfāng yě jīhū shì fù rú jiē zhī.
  • English: The brand Huawei is not only a household name in China, but also in many places around the world.
  • Analysis: This shows how the idiom can be applied to modern commercial entities like brands.
• Example 5:
  • “不要和陌生人说话”的道理是妇孺皆知的。
  • Pinyin: “Búyào hé mòshēng rén shuōhuà” de dàolǐ shì fù rú jiē zhī de.
  • English: The principle of “don't talk to strangers” is known to all.
  • Analysis: The idiom is used here to describe a widely understood social rule or piece of advice.
• Example 6:

  • Pinyin: Zài wǒmen cūn, Lǐ yīshēng de hǎoxīncháng shì fù rú jiē zhī de.

  • Pinyin: Guānyú Chángchéng de chuánshuō, kěyǐ shuō shì fù rú jiē zhī.

  • Analysis: This applies the term to cultural heritage and folklore.
• Example 8:
  • 那个贪官的丑闻很快就传得妇孺皆知。
  • Pinyin: Nàge tānguān de chǒuwén hěn kuài jiù chuán de fù rú jiē zhī.
  • English: The scandal of that corrupt official quickly became known to everyone.
  • Analysis: This shows the idiom can also be used for negative information, like a scandal or bad reputation, that spreads widely.
• Example 9:
  • 难道你不知道这件事吗？这都妇孺皆知了！
  • Pinyin: Nándào nǐ bù zhīdào zhè jiàn shì ma? Zhè dōu fù rú jiē zhī le!
  • English: You mean you don't know about this? Everybody knows about it!

  • English: The dangers of global warming are now a fact known to all.
  • Analysis: This demonstrates its use in a formal, modern context to discuss global issues.

• Fact vs. Skill: 妇孺皆知 is used for pieces of information—facts, stories, reputations, names. It is not used for skills. You would not say *“Riding a bike is 妇孺皆知.”* Instead, you would say it's a very common skill (一个很普遍的技能).
• False Friend: “Secret”: Be careful not to use it in contradictory ways. For example, you cannot say *“这是一个妇孺皆知的秘密”* (This is a widely-known secret). The correct term for an “open secret” in Chinese is 公开的秘密 (gōngkāi de mìmì).
• 妇孺皆知 vs. 家喻户晓 (jiā yù hù xiǎo): These two idioms are extremely similar and often interchangeable. 家喻户晓 literally means “every family knows and every household understands.” Both mean “household name” or “common knowledge.” If there is a subtle difference, 妇孺皆知 emphasizes the breadth of knowledge across different types of people (women, children), while 家喻户晓 emphasizes the reach into every single home. In practice, you can use them as synonyms in most cases.

• 家喻户晓 (jiā yù hù xiǎo) - A very close synonym meaning “known to every household.”
• 众所周知 (zhòng suǒ zhōu zhī) - A more formal and literary synonym, often used at the beginning of a sentence: “As everyone knows…”
• 路人皆知 (lù rén jiē zhī) - Literally “known to even a passerby on the street.” It often implies an ambition or plot that is so obvious it cannot be hidden.
• 无人不晓 (wú rén bù xiǎo) - A powerful synonym using a double negative: “There is no person who does not know.”
• 大名鼎鼎 (dà míng dǐng dǐng) - Describes a person who is extremely famous and prestigious. More about a person's great reputation than a fact's commonality.
• 耳熟能详 (ěr shú néng xiáng) - “Familiar to the ear and can be described in detail.” Used for things you've heard so many times you know them by heart, like a famous poem or song.
• 常识 (chángshí) - The noun for “common sense” or “common knowledge.” Something that is 妇孺皆知 is considered 常识.
