• Summary: Discover the profound meaning of the Chinese character 虚 (xū), a term that goes far beyond a simple translation of “empty.” This page explores how 虚 describes physical weakness (虚弱), emotional hollowness, and moral falsehood (虚伪), but also embodies the highly-prized virtue of humility (谦虚). Learn how this single character is a cornerstone in Traditional Chinese Medicine, Taoist philosophy, and everyday modern Chinese conversation.

• Pinyin (with tone marks): xū
• Part of Speech: Adjective, Adverb
• HSK Level: HSK 4
• Concise Definition: Empty, hollow; false, unreal; weak, deficient.
• In a Nutshell: 虚 (xū) is a versatile concept centered on a lack of substance. This can be literal, like a hollow space, but it's more often used to describe a lack of physical strength (weakness), a lack of truth (falseness), or a lack of ego (humility). Think of it as the opposite of “solid” or “real.” Understanding 虚 is key to grasping important cultural ideas about health, character, and philosophy in China.

• 虚 (xū): This is a phono-semantic compound character, meaning it has a part for sound and a part for meaning.
• The top part, 虍 (hū), is a variant of 虎 (hǔ), meaning “tiger.” Here, it primarily provides the phonetic sound.
• The bottom part, 丘 (qiū), means “mound” or “hill.”
• The original meaning was a large mound or ruin of a former settlement. You can imagine a great “mound” (丘) that was once bustling but is now empty and desolate—a hollow shell of its former self. This powerful image captures the essence of emptiness and lack of substance that defines 虚.

• Taoism & Philosophy: In Taoism, 虚 is not a negative concept. The *Tao Te Ching* states, “The thirty spokes unite in the one nave; but it is on the empty space for the axle, that the use of the wheel depends.” Here, “emptiness” (虚) is potential, receptiveness, and the space that allows for function. A mind that is “empty” of ego and preconceptions (虚心, xūxīn) is open to learning and wisdom. This contrasts sharply with the often-negative Western connotation of “emptiness” as a void or lack of purpose.
• Traditional Chinese Medicine (TCM): 虚 is a fundamental diagnostic concept in TCM, where it means “deficiency.” You'll frequently hear terms like 气虚 (qì xū), a deficiency of vital energy (qi), or 血虚 (xuè xū), a blood deficiency. This isn't just “being weak”; it's a specific type of imbalance in the body's systems that TCM aims to correct with herbs, diet, and acupuncture. A doctor might tell you, “你身体有点虚 (nǐ shēntǐ yǒudiǎn xū),” meaning “Your body is a bit deficient/weak.”
• The Virtue of Humility: One of the most important positive uses of 虚 is in the word 谦虚 (qiānxū), meaning “modest” or “humble.” The idea is that one is “empty” of arrogance and pride. This is a highly respected trait in Chinese culture, where self-effacement is often valued over self-promotion.

The meaning of 虚 changes dramatically based on the words it's paired with.

• Describing Physical Weakness (Negative):
  • When someone is recovering from an illness or is generally frail, you can say their body is 虚 (xū) or 虚弱 (xūruò). It implies a deep-seated lack of energy, not just temporary tiredness.
• Describing Character and Actions (Negative):
  • 虚伪 (xūwěi): Hypocritical or phony. Someone whose words and actions are “empty” of truth.
  • 虚荣 (xūróng): Vain. Describes someone who chases “empty glory” like status or luxury goods without inner substance.
  • 心里发虚 (xīnlǐ fā xū): To feel a lack of confidence, often mixed with guilt or nervousness. It's the feeling you get when you've done something wrong or are unprepared for a test. Your heart feels “hollow” or “empty” of courage.
• Describing Abstract Concepts (Neutral/Negative):
  • 虚构 (xūgòu): Fictional, fabricated. Used for stories, characters, and plots.
  • 虚名 (xūmíng): An “empty name” or undeserved reputation.
• Describing Positive Virtues:
  • 谦虚 (qiānxū): Humble, modest. A highly valued personal quality.
  • 虚心 (xūxīn): Literally “empty heart/mind.” It means to be open-minded and eager to learn from others.

• Example 1:
  • 他大病初愈，身体还很虚。
  • Pinyin: Tā dàbìng chū yù, shēntǐ hái hěn xū.
  • English: He just recovered from a major illness, so his body is still very weak.
  • Analysis: Here, 虚 refers to the physical state of deficiency and weakness common after an illness, a core concept in TCM.
• Example 2:
  • 中国人一般认为谦虚是一种美德。
  • Pinyin: Zhōngguó rén yībān rènwéi qiānxū shì yī zhǒng měidé.
  • English: Chinese people generally consider modesty a virtue.
  • Analysis: This shows the positive side of 虚. In 谦虚 (qiānxū), being “empty” of arrogance is a highly respected trait.
• Example 3:
  • 我没复习，明天要考试了，心里很虚。
  • Pinyin: Wǒ méi fùxí, míngtiān yào kǎoshì le, xīnlǐ hěn xū.
  • English: I didn't review, and the test is tomorrow, so I'm feeling really nervous and unconfident.
  • Analysis: 心里虚 (xīnlǐ xū) is a fantastic phrase that captures the feeling of being unprepared or guilty. Your confidence is “hollow.”
• Example 4:
  • 我觉得他这个人很虚伪，嘴上说一套，背后做一套。
  • Pinyin: Wǒ juédé tā zhège rén hěn xūwěi, zuǐ shàng shuō yī tào, bèihòu zuò yī tào.
  • English: I think he is very hypocritical; he says one thing and does another.
  • Analysis: 虚伪 (xūwěi) is a strong negative adjective for describing someone whose character is “false” or “empty” of sincerity.
• Example 5:
  • 我们应该虚心向有经验的同事学习。
  • Pinyin: Wǒmen yīnggāi xūxīn xiàng yǒu jīngyàn de tóngshì xuéxí.
  • English: We should humbly (with an open mind) learn from our experienced colleagues.
  • Analysis: Similar to 谦虚, 虚心 (xūxīn) is a positive term encouraging one to have an “empty mind,” free of ego, in order to learn.
• Example 6:
  • 别被他的虚名骗了，他其实没什么真本事。
  • Pinyin: Bié bèi tā de xūmíng piàn le, tā qíshí méishénme zhēn běnshì.
  • English: Don't be fooled by his undeserved reputation; he doesn't actually have any real skills.
  • Analysis: 虚名 (xūmíng) means an “empty name” or “hollow fame,” a reputation without substance to back it up.
• Example 7:
  • 这个故事完全是虚构的，请勿当真。
  • Pinyin: Zhège gùshì wánquán shì xūgòu de, qǐng wù dāngzhēn.
  • English: This story is completely fictional; please don't take it as real.
  • Analysis: 虚构 (xūgòu) is the standard word for “fiction” or “fabricated,” where 虚 means “unreal.”
• Example 8:
  • 中医说我有点气虚，建议我多休息，吃点红枣。
  • Pinyin: Zhōngyī shuō wǒ yǒudiǎn qìxū, jiànyì wǒ duō xiūxí, chī diǎn hóngzǎo.
  • English: The Traditional Chinese Medicine doctor said I have a slight qi deficiency and suggested I rest more and eat some red dates.
  • Analysis: This is a direct and very common application of 虚 in the context of TCM.
• Example 9:
  • 她的虚荣心很强，总是买超出自己能力范围的奢侈品。
  • Pinyin: Tā de xūróngxīn hěn qiáng, zǒng shì mǎi chāochū zìjǐ nénglì fànwéi de shēchǐpǐn.
  • English: Her vanity is very strong; she always buys luxury goods that are beyond her means.
  • Analysis: 虚荣 (xūróng) means “vanity,” literally “empty glory,” the pursuit of superficial praise and status.
• Example 10:
  • 这座城市曾经很繁华，现在只剩下一片空虚的废墟。
  • Pinyin: Zhè zuò chéngshì céngjīng hěn fánhuá, xiànzài zhǐ shèng xià yī piàn kōngxū de fèixū.
  • English: This city was once prosperous, but now only empty ruins are left.
  • Analysis: 空虚 (kōngxū) combines 空 (empty) and 虚 (hollow) to describe a deep sense of emptiness, both physically and emotionally.

• 虚 (xū) vs. 空 (kōng): This is a critical distinction for learners. Both can be translated as “empty.”
  • 空 (kōng) usually refers to physical emptiness. A bottle is empty (瓶子是空的 píngzi shì kōng de). A room is vacant (空房间 kōng fángjiān). It's objective and tangible.
  • 虚 (xū) refers to a lack of substance, essence, or strength. A promise is empty/hollow (虚假的承诺 xūjiǎ de chéngnuò). A body is weak (身体很虚 shēntǐ hěn xū). It's more abstract and qualitative.
  • Incorrect Usage: 你可以说 “这个杯子是空的” (The cup is empty), but you cannot say “这个杯子是虚的”.
• Not Always Negative: Because of words like 虚伪 (hypocritical) and 虚弱 (weak), many learners assume 虚 is always a bad word. Remember that it's the foundation of the highly positive virtues of 谦虚 (modesty) and 虚心 (open-mindedness). Context is everything.
• Feeling “Hollow” vs. “Empty”: The phrase 心里发虚 (xīnlǐ fā xū) is often translated as “feeling nervous” or “lacking confidence.” It's not the same as the Western concept of “feeling empty” in a sad, existential way. That feeling is better described by 空虚 (kōngxū). 心里发虚 is specifically about feeling unconfident because you know you are unprepared or in the wrong.
