解説扫描 in your Level:

At the A1 level, you only need to know '扫描' (sǎomiáo) in the context of very basic daily actions, specifically using your phone. In modern China, you cannot survive without 'scanning' QR codes. You will see the characters on signs in restaurants, shops, and on buses. At this stage, think of it as a magic button on your phone. You don't need to worry about complex grammar; just associate '扫描' with the action of pointing your camera at a square QR code. You will mostly hear it as '扫一扫' (sǎo yī sǎo), which is the casual way to say 'give it a scan.' If a shopkeeper points to a QR code and says '扫一下' (sǎo yīxià), they want you to scan it to pay. Focus on the physical action and the visual of the QR code.

扫描 30秒で

扫描 (sǎomiáo) is the standard Mandarin Chinese verb for 'to scan,' covering document digitization, mobile QR code interactions, and advanced medical imaging processes.
The word consists of 'sǎo' (sweep) and 'miáo' (trace), reflecting the mechanical action of a scanner moving across a surface to capture data.
In daily life, it is most commonly used for mobile payments (扫一扫), making it one of the most essential verbs for modern Chinese travel.
It should not be confused with 'skimming' a book (浏览) or 'sweeping' the floor (扫地), as it strictly implies a technological or systematic process.

The Chinese word 扫描 (sǎomiáo) is a compound verb that perfectly encapsulates the technological bridge between the physical and digital worlds. At its core, it combines 扫 (sǎo), which means to sweep or to brush, with 描 (miáo), which means to trace, sketch, or depict. Together, they describe the action of a beam of light or a sensor 'sweeping' across a surface to 'trace' and capture its details. In modern Mandarin, this is the primary term for scanning documents, but its usage has exploded in the last decade due to the ubiquity of mobile technology and medical imaging.

Digital Context: In everyday life, you will most frequently hear this word in the context of mobile payments and social connectivity. China's digital economy revolves around the phrase 扫一扫 (sǎo yī sǎo), which literally means 'scan a scan.' Whether you are paying for groceries at a wet market, adding a new friend on WeChat, or unlocking a shared bicycle, you are performing a 扫描 of a QR code.

请用手机扫描屏幕上的二维码以完成支付。(Please use your phone to scan the QR code on the screen to complete the payment.)

Medical and Scientific Context: Beyond consumer electronics, 扫描 is the standard term for diagnostic imaging like CT scans, MRI, or PET scans. In these instances, the 'scanning' refers to the machine's internal sensors capturing cross-sectional images of the human body. Scientists also use it when discussing electron microscopes or radar systems that 'sweep' across an area to detect objects.

医生建议他做一个全身扫描以检查潜在的健康问题。(The doctor suggested he undergo a full-body scan to check for potential health issues.)

Furthermore, in the corporate and administrative world, 扫描 is essential for digitizing archives. When you take a physical contract and turn it into a PDF, you are 'scanning' it. The noun form of the device is 扫描仪 (sǎomiáoyí), where 仪 denotes an instrument or apparatus. Understanding this word is crucial for navigating any modern Chinese environment, from the high-tech hospitals in Shanghai to the local fruit stall in a small village.

Using 扫描 (sǎomiáo) correctly involves understanding its role as a transitive verb. Most commonly, it follows the structure: [Subject] + 扫描 + [Object]. The object is usually the thing being digitized or analyzed. Because it is a two-character verb, it can be reduplicated in the form 扫描扫描 (sǎomiáo sǎomiáo) or used with the 'one' construction 扫一扫 (sǎo yī sǎo) to indicate a quick or brief action, which is very common in casual speech.

Direct Object Usage: When scanning a physical object, the object comes directly after the verb. For example, 'I am scanning the document' is 我在扫描文件 (Wǒ zài sǎomiáo wénjiàn). If you are using a specific tool, you use the 'use' (用 yòng) construction: 用扫描仪扫描 (yòng sǎomiáoyí sǎomiáo).

请把这些老照片扫描进电脑里保存。(Please scan these old photos into the computer to save them.)

Resultative Complements: To indicate the result of the scan, you can add complements like 好 (hǎo) or 完 (wán). For instance, 扫描好了 (sǎomiáo hǎo le) means 'finished scanning and it's ready.' If the scan fails, you might say 扫描不出来 (sǎomiáo bù chūlái), meaning the scanner cannot read the data.

这个二维码太模糊了，手机扫描不出来。(This QR code is too blurry; the phone cannot scan it.)

In more formal or academic writing, 扫描 can also function as a noun. For example, 'Laser scanning technology' is 激光扫描技术 (jīgūāng sǎomiáo jìshù). When used as a noun, it often appears as part of a longer compound noun describing a specific process or field of study. In literary contexts, it might describe a radar 'scanning' the horizon for enemies, adding a sense of vigilance and mechanical precision to the narrative.

If you spend a single day in a Chinese city, you will hear or see the word 扫描 (sǎomiáo) or its colloquial variant 扫 (sǎo) dozens of times. The most common environment is the retail sector. Since China has largely skipped the credit card era and moved straight to mobile payments, every transaction involves a scan. Shopkeepers will often say, “我扫你还是你扫我？” (Wǒ sǎo nǐ háishì nǐ sǎo wǒ?), which means 'Do I scan you (your payment code) or do you scan me (my QR code)?' While they use the shorthand 扫, the underlying concept is 扫描.

The Office Environment: In a Chinese office, the 'all-in-one' printer/scanner/copier is a central hub. You will hear colleagues ask, “你能帮我把这份合同扫描成PDF吗？” (Nǐ néng bāng wǒ bǎ zhè fèn hétóng sǎomiáo chéng PDF ma?). Here, it is strictly about document digitization and is a standard administrative task.

请在进入图书馆前，扫描您的学生证。(Please scan your student ID before entering the library.)

Public Transportation and Security: At subway stations and airports, security personnel use scanners to check luggage. They might say, “请将行李放在传送带上进行扫描。” (Qǐng jiāng xínglǐ fàng zài chuánsòngdài shàng jìnxíng sǎomiáo.). Furthermore, facial recognition technology, which 'scans' faces for identity verification, is increasingly common at turnstiles and checkpoints, often referred to as 人脸扫描 (rénliǎn sǎomiáo).

安检员正在用探测器扫描旅客的随身物品。(The security officer is using a detector to scan passengers' carry-on items.)

In the creative and tech industries, you will hear it in discussions about 3D printing or VR. 3D扫描 (3D sǎomiáo) is the process of capturing a physical object's shape to create a digital 3D model. In these contexts, the word carries a futuristic, high-precision connotation. Whether it is a low-tech scan of a receipt or a high-tech scan of a biological specimen, 扫描 is the linguistic tool that describes the capture of data through light and sensors.

While 扫描 (sǎomiáo) is relatively straightforward, English speakers often make mistakes by over-extending its meaning or confusing it with similar-sounding words. The most common error is using 扫描 when you actually mean 'to skim' a book or a text. In English, we 'scan' a page to find a keyword. In Chinese, if you use 扫描 for this, it sounds like you are a robot digitizing the page. For 'skimming,' you should use 浏览 (liú lǎn) or 略读 (lüèdú).

Confusion with 'Sweep' (扫): Because 扫 (sǎo) means 'to sweep,' beginners sometimes confuse 扫描 with 扫地 (sǎodì - to sweep the floor). Remember that 扫描 always involves a technological or systematic 'tracing' (描), not a broom. You cannot 'scan' the floor with a broom; you 'sweep' it.

错误：我扫描了一下这本书，找到了我的名字。(Wrong: I 'scanned' [digitized] the book and found my name.)
正确：我浏览了一下这本书，找到了我的名字。(Correct: I skimmed the book and found my name.)

Mistaking 'Trace' (描): Another mistake involves the second character 描 (miáo). Some learners confuse 扫描 with 描写 (miáoxiě - to describe/depict). While both involve 'drawing' a picture of something, 描写 is a literary act of using words to describe a scene, whereas 扫描 is a technical act of data capture.

医生正在扫描病人的大脑，而不是在“描写”它。(The doctor is scanning the patient's brain, not 'describing' it.)

Finally, pay attention to the measure words. While 扫描 is a verb, the act itself can be counted using 次 (cì - time) or 遍 (biàn - time/round). Saying “扫描一个” is only correct if you are scanning one object. If you mean the action of scanning, say “扫描一次”. Misusing these makes your Chinese sound unnatural and 'clunky' to native speakers.

Mandarin has several words that overlap with the English concept of 'scanning.' Choosing the right one depends on whether you are talking about technology, human sight, or data processing. 扫描 (sǎomiáo) is almost always the technological choice. Let's look at the alternatives to see where they differ.

扫描 vs. 浏览 (liú lǎn): As mentioned, 浏览 is used for 'browsing' or 'skimming.' It implies a casual, human action, like looking through a magazine or a website. 扫描 is systematic and exhaustive, usually performed by a machine. You 浏览 a web page, but a search engine 扫描 the internet for keywords.
扫描 vs. 搜索 (sōusuǒ): 搜索 means 'to search' or 'to hunt for.' While a radar might 扫描 the sky, its purpose is to 搜索 for enemy planes. 扫描 is the physical method (the sweeping motion); 搜索 is the goal (finding something).
扫描 vs. 复印 (fùyìn): In the office, 复印 means 'to photocopy.' Many people confuse these because the machine is the same. 复印 results in a physical paper copy, while 扫描 results in a digital file. If you want a paper copy, don't ask for a 扫描.

我先扫描了文件，然后把电子档发给了老板。(I first scanned the document, then sent the digital file to the boss.)

In specific technical fields, you might encounter 探测 (tàncè) which means 'to probe' or 'detect,' often used for underwater sonar or space probes. While 扫描 is part of the 探测 process, 探测 is more about the discovery of unknown data. In summary, use 扫描 when light or sensors are 'sweeping' to create a digital representation of something physical.

How Formal Is It?

豆知識

The character 扫 (sǎo) used to be much more complex before simplification (掃). The right side showed a broom over a hand. Now it is simplified to a hand (扌) and a 'mountain-like' shape.

発音ガイド

UK /sǎʊ mjǎʊ/

US /sǎʊ mjǎʊ/

The primary stress is on the first syllable 'sǎo', which is held slightly longer due to its third tone.

よくある間違い

Pronouncing 'sǎo' as a first tone (sāo), which sounds like 'frivolous'.
Pronouncing 'miáo' as a fourth tone (miào), which sounds like 'temple' or 'wonderful'.
Failing to dip the voice low enough for the third tone on 'sǎo'.
Merging the two syllables into one sound.
Over-emphasizing the 'i' in 'miáo', making it sound like 'mee-ao' instead of a smooth glide.

難易度

よくある間違い

Using 扫描 for 'sweeping' the floor. → 扫地 (sǎodì)
扫描 is only for technological scanning. 扫 means sweep, but 扫描 is a compound for sensors and light.
Using 扫描 for 'skimming' a book. → 浏览 (liúlǎn)

ヒント

Payment Tip

When paying in China, if you want the merchant to scan your code, show your screen and say '你扫我' (Nǐ sǎo wǒ). If you want to scan theirs, say '我扫你' (Wǒ sǎo nǐ).

Resultative Complements

Always use '好' (hǎo) or '完' (wán) to indicate that a scanning task is finished. For example, '文件扫描好了' sounds much more natural than just '文件扫描了'.

Office Distinction

Be careful not to confuse 扫描 with 复印 (photocopy). If you ask for a 扫描, they will send you a file. If you want paper, ask for 复印.

Tone Accuracy

Make sure to emphasize the third tone (falling-rising) in 'sǎo'. If you say it with a flat tone, it might be misunderstood in fast speech.

Antivirus Context

When your computer is slow, you can say '我在扫描病毒' (I am scanning for viruses). This is a very common phrase in IT support.

Health Context

語源

The term 扫描 is a modern technical coinage. '扫' (sǎo) is an ancient character originally depicting a hand holding a broom made of plants, meaning to sweep. '描' (miáo) dates back to at least the Song Dynasty, meaning to trace or sketch. The combination was created to translate the English concept of 'scanning' as technology emerged.

元の意味： The literal combination means 'to sweep and trace,' which perfectly describes how early cathode-ray tube (CRT) televisions and scanning devices worked by sweeping a beam across a surface.

Sino-Tibetan (Mandarin Chinese).

文化的な背景

Be aware that while scanning is convenient, there are ongoing discussions in China about the privacy implications of 'facial scanning' (人脸扫描) and data tracking.

In English-speaking countries, 'scanning' is often associated with office work or self-checkout. In China, it is much more deeply integrated into social media and interpersonal relationships.
