• Pinyin (with tone marks): tóurù
• Part of Speech: Verb, Adjective
• HSK Level: 5
• Concise Definition: To put into, to throw into; to invest; to be absorbed or engrossed in.
• In a Nutshell: At its heart, 投入 (tóurù) is about putting something in. This can be literal, like investing money into a company, or figurative, like “throwing” all your mental energy into a book or a project. It captures the idea of commitment and deep engagement, whether with resources or with one's own attention.

• 投 (tóu): This character means “to throw,” “to cast,” or “to put in.” The left side, 扌 (shǒu), is the “hand” radical, indicating an action done with the hands. The right side, 殳 (shū), originally depicted a weapon and here provides the sound. Think of it as using your hand (扌) to throw or place something.
• 入 (rù): This character means “to enter” or “to go into.” It's a simple pictograph that looks like a wedge or a doorway, illustrating the concept of entry.
• The two characters combine literally to mean “throw into.” This beautifully captures all of the word's meanings: you “throw money into” a project (invest), you “throw yourself into” your work (engrossed), and you put a new machine “into” operation (put into use).

While 投入 (tóurù) doesn't carry the same ancient philosophical weight as terms like 关系 (guānxi), it strongly reflects modern Chinese values of dedication, hard work, and single-minded focus. In both academic and professional environments, being 投入 is highly praised. It signifies more than just participation; it implies a deep level of commitment and mental absorption. This can be contrasted with the Western ideal of “multitasking.” While multitasking is sometimes seen as a skill in the West, Chinese culture often places a higher value on doing one thing at a time with complete focus. The state of being 投入 is seen as the key to achieving high-quality results. It aligns with the concept of “工匠精神” (gōngjiàng jīngshén), the “spirit of the artisan,” which reveres craftsmanship, precision, and deep dedication to one's work. Praising an employee or a student for being “很投入” (hěn tóurù - very engaged) is a significant compliment.

投入 is a common and flexible word used in various contexts.

• As a Verb: To Invest (Resources)
  • This is the most direct meaning. It's used for investing money, resources, time, or energy into a project, company, or goal.
  • Example: 公司决定投入一百万发展新技术。 (The company decided to invest one million to develop new technology.)
• As a Verb: To Put into Operation
  • This is a common fixed phrase, 投入使用 (tóurù shǐyòng), meaning “to put into use/operation.” It's frequently seen in news reports about infrastructure or new products.
  • Example: 这条新地铁线明天将正式投入使用。 (This new subway line will officially be put into operation tomorrow.)
• As an Adjective: Engrossed / Absorbed / Immersed
  • This is perhaps the most common conversational use. It describes a person's state of being completely focused on and engaged with something, losing track of their surroundings.
  • Example: 他看书看得太投入了，我叫了他好几声他都没听见。 (He was so engrossed in his book that he didn't hear me after I called him several times.)

  • Analysis: In this sentence, 投入 functions as a noun, meaning “investment” or “input.”

• 投入 (tóurù) vs. 投资 (tóuzī): This is the most common point of confusion.
  • 投资 (tóuzī) almost exclusively refers to financial investment with the expectation of a monetary return. You 投资 in the stock market, real estate, or a business.
  • 投入 (tóurù) is much broader. You can 投入 money, but you can also 投入 time, energy, emotion, and effort. If you spend all weekend studying for an exam, you should say “我投入了很多时间” (I invested a lot of time), not “我投资了很多时间.” Using 投资 for time or energy sounds unnatural.
  • Rule of thumb: If the goal is financial profit, use 投资. For anything else (time, effort, focus, emotion), use 投入.
• Adjective Usage: Remember that when you say someone is “很投入” (hěn tóurù), it means they are “very engrossed/absorbed,” not “very invested” in a financial sense.
  • Incorrect: “He is very invested in our company” → “他很投入我们的公司。” (This is awkward).
  • Correct: “他对我们公司的项目很投入。” (Tā duì wǒmen gōngsī de xiàngmù hěn tóurù) - “He is very engaged in our company's project.” Or, for financial investment: “他在我们公司投资了很多钱。” (Tā zài wǒmen gōngsī tóuzīle hěnduō qián.) - “He invested a lot of money in our company.”

• 投资 (tóuzī) - To invest (financially). The more specific term for investing money for profit.
• 专心 (zhuānxīn) - To concentrate; to be focused. A close synonym for the “engrossed” meaning of 投入, but it emphasizes the mind's focus specifically.
• 沉浸 (chénjìn) - To be immersed in. Very similar to the adjective form of 投入, often used to describe immersive experiences like VR or reading a captivating story.
• 奉献 (fèngxiàn) - To dedicate; to devote. A more formal and noble term, often implying selfless contribution to a cause or society.
• 精力 (jīnglì) - Energy; vigor. The personal resource that one can 投入 into a task.
• 热情 (rèqíng) - Enthusiasm; passion. The feeling you have when you are fully 投入 in something you love.
• 使用 (shǐyòng) - To use. Appears in the common and important phrase 投入使用 (to put into operation).
• 专注 (zhuānzhù) - To focus on. A verb describing the act of concentrating, which results in the state of being 投入.
