• Pinyin (with tone marks): nǎo lì
• Part of Speech: Noun
• HSK Level: HSK 5
• Concise Definition: The power or capacity of the brain; intellect or mental energy.
• In a Nutshell: Think of 脑力 (nǎolì) as your brain's battery level or its muscle power. It's the finite resource you use for any task that isn't purely physical: solving a math problem, writing a report, having a deep conversation, or learning a new language. When you feel mentally exhausted after a long day of studying, it’s because you've used up a lot of your 脑力. It’s a resource that can be depleted and needs to be recharged.

• 脑 (nǎo): Brain. The left part, 月 (yuè), is a radical that often relates to the body or flesh. The right part provides the sound. Together, they signify the physical organ of the brain.
• 力 (lì): Power, strength, force. This character is a pictograph of a plow or a person's arm and shoulder, symbolizing the exertion of strength.
• The two characters combine literally to mean “brain power.” This is a very direct and intuitive combination: the strength and energy that comes from your brain.

The concept of 脑力 (nǎolì) is deeply woven into Chinese culture, which has historically placed a high value on intellectual pursuits and education. This stems from a long tradition revering scholars and the imperial examination system (科举, kējǔ), which for centuries was the primary path to social advancement. This cultural value is best understood through the stark contrast between 脑力劳动 (nǎolì láodòng - mental labor) and 体力劳动 (tǐlì láodòng - physical labor). In the West, this is similar to the “white-collar vs. blue-collar” distinction. However, in China, the preference for 脑力劳动 often carries a stronger cultural weight. A job that requires brainpower is traditionally seen as more prestigious, stable, and desirable than a job requiring physical strength. This mindset, while evolving, still influences career choices, family expectations, and social status in modern China. Having good 脑力 is not just about being smart; it's about having the capacity for a type of work that is culturally esteemed.

脑力 is a common term used in various everyday contexts.

• In the Workplace: People often categorize jobs based on the type of effort required. You might hear someone say, “我的工作主要是脑力劳动” (Wǒ de gōngzuò zhǔyào shi nǎolì láodòng), meaning “My job is mainly mental labor.” It's also used to describe mental fatigue: “今天开了五个会，脑力都用光了” (Jīntiān kāile wǔ gè huì, nǎolì dōu yòng guāng le), meaning “I had five meetings today, my brainpower is completely used up.”
• In Education: Students preparing for major exams like the Gaokao (高考) are seen as engaging in intense 脑力 work. Parents might buy supplements or certain foods that are advertised to “boost 脑力” (提高脑力, tígāo nǎolì) for their children.
• In Health and Lifestyle: The concept of “recharging” one's 脑力 is common. Activities like sleeping well, exercising, or taking a break are seen as ways to 恢复脑力 (huīfù nǎolì), or recover mental energy.

The connotation of 脑力 is generally neutral to positive. Possessing strong 脑力 is a highly valued attribute.

• Example 1:
  • 下棋是一种很好的脑力锻炼。
  • Pinyin: Xià qí shì yī zhǒng hěn hǎo de nǎolì duànliàn.
  • English: Playing chess is a very good form of mental exercise.
  • Analysis: This sentence uses 脑力 in the context of improving one's mental skills, much like one would exercise their body.
• Example 2:
  • 这个项目太复杂了，非常消耗脑力。
  • Pinyin: Zhège xiàngmù tài fùzá le, fēicháng xiāohào nǎolì.
  • English: This project is too complex; it really consumes a lot of brainpower.
  • Analysis: Here, 消耗 (xiāohào - to consume) is paired with 脑力 to express that a task is mentally draining.
• Example 3:
  • 和体力劳动相比，我更喜欢脑力劳动。
  • Pinyin: Hé tǐlì láodòng xiāngbǐ, wǒ gèng xǐhuān nǎolì láodòng.
  • English: Compared to physical labor, I prefer mental labor.
  • Analysis: This is a classic sentence that directly contrasts 脑力劳动 with its antonym, 体力劳动 (tǐlì láodòng).
• Example 4:
  • 连续工作了十个小时，我的脑力已经跟不上了。
  • Pinyin: Liánxù gōngzuò le shí ge xiǎoshí, wǒ de nǎolì yǐjīng gēn bu shàng le.
  • English: After working for ten hours straight, my brainpower can no longer keep up.
  • Analysis: 跟不上 (gēn bu shàng - can't keep up) is a common and vivid way to describe mental exhaustion or the inability to think clearly anymore.
• Example 5:
  • 解决这个问题需要集体脑力，而不是一个人。
  • Pinyin: Jiějué zhège wèntí xūyào jítǐ nǎolì, ér búshì yī ge rén.
  • English: Solving this problem requires collective brainpower, not just one person.
  • Analysis: This shows that 脑力 can be conceptualized as a collective resource, similar to the English term “brainstorming” or “group effort.”
• Example 6:
  • 随着年龄的增长，一些人的脑力会逐渐下降。
  • Pinyin: Suízhe niánlíng de zēngzhǎng, yīxiē rén de nǎolì huì zhújiàn xiàjiàng.
  • English: As people age, some may experience a gradual decline in mental acuity.
  • Analysis: This sentence links 脑力 to the natural process of aging, referring to cognitive function and mental sharpness.
• Example 7:
  • 多吃坚果对提高脑力有好处。
  • Pinyin: Duō chī jiānguǒ duì tígāo nǎolì yǒu hǎochu.
  • English: Eating more nuts is good for boosting brainpower.
  • Analysis: This reflects the common belief in Chinese culture and traditional medicine that certain foods can enhance mental function.
• Example 8:
  • 程序员是一个高强度的脑力工作。
  • Pinyin: Chéngxùyuán shì yī ge gāo qiángdù de nǎolì gōngzuò.
  • English: Being a programmer is a high-intensity mental job.
  • Analysis: 高强度 (gāo qiángdù - high-intensity) is often used to describe jobs that are very demanding, whether physically or mentally.
• Example 9:
  • 你需要休息一下，恢复脑力。
  • Pinyin: Nǐ xūyào xiūxi yīxià, huīfù nǎolì.
  • English: You need to rest for a bit to recover your mental energy.
  • Analysis: 恢复 (huīfù - to recover, restore) is the verb frequently paired with 脑力 to talk about recharging one's mental batteries.
• Example 10:
  • 这份报告写得我脑力透支了。
  • Pinyin: Zhè fèn bàogào xiě de wǒ nǎolì tòuzhī le.
  • English: Writing this report has completely overdrawn my brainpower.
  • Analysis: 透支 (tòuzhī) is a financial term meaning “to overdraw” an account. Using it with 脑力 creates a powerful metaphor for being utterly mentally spent, like you've gone into “mental debt.”

• 脑力 (nǎolì) vs. 智力 (zhìlì) - “Brainpower” vs. “Intelligence”:
  • A crucial mistake for learners is to use 脑力 and 智力 (zhìlì - intelligence/IQ) interchangeably.
  • 脑力 (nǎolì) is a resource, a capacity for mental work that can be used up and replenished. It's about mental stamina. You can say: “我今天脑力用完了” (My brainpower is used up today).
  • 智力 (zhìlì) is a more stable attribute, like one's IQ. It describes inherent intellectual ability. You would say: “他的智力很高” (His intelligence is very high).
  • Incorrect: “我今天智力用完了。” (My intelligence is used up today.) This sounds nonsensical, as if you've become permanently less smart.
• “Mental” is not always “脑力”:
  • While 脑力 relates to the mind, it specifically refers to intellectual effort. Do not use it for emotional or psychological states.
  • For “mental health,” use 心理健康 (xīnlǐ jiànkāng).
  • For “mental state” or “frame of mind,” use 心态 (xīntài) or 心理状态 (xīnlǐ zhuàngtài).
  • Incorrect: “他的脑力有问题。” This would be interpreted as “There's a problem with his brainpower (he can't think well),” not “He has mental health problems.”

• 体力 (tǐlì) - The direct antonym of 脑力; it means physical strength or physical power.
• 智力 (zhìlì) - Intelligence, IQ. A measure of innate intellectual ability, whereas 脑力 is the energy to use that ability.
• 脑力劳动 (nǎolì láodòng) - Mental labor, white-collar work. The term that culturally contrasts with physical labor.
• 用脑 (yòng nǎo) - A verb phrase meaning “to use one's brain.” Example: “这个问题你得好好用脑想一想。” (You need to use your brain to think this problem over carefully.)
• 费脑子 (fèi nǎozi) - A common colloquial phrase meaning “(to be) mentally taxing” or “to require a lot of thought.” It literally means “to expend brain.”
• 脑子 (nǎozi) - The brain (physical organ), and colloquially, the mind. More general than 脑力.
• 脑洞 (nǎodòng) - Modern slang literally meaning “brain hole.” It refers to a person's wild imagination or a highly creative, bizarre idea.
• 心理 (xīnlǐ) - Psychology, mentality. Refers to the emotional and psychological aspects of the mind, distinct from the intellectual effort of 脑力.
• 精力 (jīnglì) - Energy, vigor. A broader term that encompasses both mental and physical energy. You can say “我没有精力了” (I have no energy left), and it can mean either or both.
