解説口岸 in your Level:

At the A1 level, you only need to know that 口岸 (kǒu'àn) is a word related to travel and borders. Think of it as a 'gate' for a country. You might see it on signs at an airport or a train station that goes to another country. It's a place where you show your passport. Even though the word looks complicated, just remember the first part '口' means 'mouth'—it's the mouth of the country where people enter. You don't need to use it in complex sentences yet, but recognizing it on a map or a sign is very helpful for a traveler. For example, if you see '深圳口岸', you know that is where you go to enter or leave the city of Shenzhen. It is a noun, and it usually comes after the name of a place. Don't worry about the 'shore' part of the word for now; just treat it as a single block of meaning that says 'International Crossing.'

At the A2 level, you should understand that 口岸 (kǒu'àn) is the formal word for a 'port' or 'border crossing.' You will use this word when talking about traveling between countries or special regions like Hong Kong. You can use it in simple sentences like '我们在口岸见面' (We meet at the port) or '这个口岸很大' (This port is very big). You should also begin to notice it in compound words like '口岸城市' (port city). It is important to distinguish it from '海关' (hǎiguān), which is the 'Customs' office. You go *to* the 口岸 to find the 海关. In your studies, you might encounter it in lessons about travel, logistics, or geography. It is a very common noun in China because of the many land and sea borders the country has. Practice saying the name of a crossing followed by '口岸' to sound more like a native speaker.

By B1, you should be able to use 口岸 (kǒu'àn) in more professional and descriptive contexts. You should understand that it refers to any designated point of entry or exit for international trade and travel, including airports, sea ports, and land crossings. You should be comfortable using verbs like '开放' (to open) and '管理' (to manage) with 口岸. For example: '政府正在开放更多的贸易口岸' (The government is opening more trade ports). You should also understand its role in logistics; if you are talking about importing goods, you would talk about the '口岸手续' (port procedures). This level requires you to distinguish 口岸 from '港口' (harbor). Remember that '港口' is the physical place for ships, while 口岸 is the legal gateway. You might hear this word in news reports about the economy or tourism, and you should be able to summarize those reports using the word correctly.

At the B2 level, 口岸 (kǒu'àn) becomes a key term for discussing international relations, trade policy, and economic development. You should be able to discuss the '口岸经济' (port economy) and how the efficiency of a 口岸 affects a region's growth. You should also be aware of the different types of ports, such as '一类口岸' (First-tier ports) which are directly approved by the central government. At this stage, you should be able to write essays or give presentations about globalization, using 口岸 to describe the nodes of global connectivity. You will encounter the word in more complex grammatical structures, such as '口岸通关便利化' (facilitation of port clearance). You should also understand the historical weight of the term, especially in relation to China's 'Opening Up' policy, where the development of specific ports was a major strategic move. Your usage should reflect an understanding of the word's administrative and formal nuances.

口岸 30秒で

A formal term for any international gateway (air, land, or sea) where customs and immigration are present.
Literally means 'mouth of the shore,' but functions as 'Point of Entry' in administrative and legal contexts.
Essential for discussing trade, logistics, and international travel, distinguishing itself from the physical 'harbor' (港口).
Commonly used in compound words like '口岸城市' (port city) and '口岸通关' (port customs clearance).

The term 口岸 (kǒu'àn) is a fundamental concept in the context of international travel, logistics, and geography in the Chinese-speaking world. While a beginner might simply translate it as 'port,' its meaning is significantly broader and more specialized than the English word 'harbor.' In Chinese, kǒu (口) means 'mouth' or 'opening,' and àn (岸) means 'shore' or 'bank.' Together, they represent a gateway through which people, goods, and vehicles enter or leave a country. Unlike a physical harbor which is strictly for ships, a 口岸 can be a sea port, a land border crossing, or an international airport.

Functional Definition: A designated location by the state for international trade and personnel exchange, equipped with customs, inspection, and quarantine facilities.

You will encounter this word most frequently when dealing with official documentation, travel news, or economic reports. It is the administrative term for any 'Point of Entry.' For example, if you are traveling from Hong Kong to Shenzhen by foot, you are passing through a land 口岸. If you are shipping electronics from Shanghai to Los Angeles, the goods depart from a sea 口岸. The term emphasizes the legal and regulatory aspect of the location rather than just the physical structure.

这个城市是一个重要的贸易口岸。(This city is an important trade port.)

Historically, the concept of 口岸 was tied to the 'Treaty Ports' of the nineteenth century, but today it represents the modernization of China's connectivity. It is a 'high-register' word, meaning it sounds professional and precise. In casual conversation, people might say '海关' (Customs) when they are actually referring to the physical space of the 口岸, but using the correct term shows a higher level of linguistic proficiency.

Classification: Classified into 'First-tier' (opened to foreign vessels/nationals) and 'Second-tier' (restricted or domestic-focused) ports.

In the modern economy, the efficiency of a 口岸 determines the speed of the supply chain. Terms like '口岸通关' (port clearance) are buzzwords in business news. When you hear about the 'Greater Bay Area' or the 'Belt and Road Initiative,' the development of these gateways is a central theme. It represents the 'mouth' through which the nation breathes in terms of global interaction.

由于节日，口岸非常拥挤。(Due to the holiday, the border crossing is very crowded.)

To use this word correctly, think about the context of 'crossing a border.' If there is a passport control and a customs officer, you are likely at a 口岸. It is the official gateway of the sovereign state.

Using 口岸 (kǒu'àn) correctly requires understanding its role as a noun that often acts as the object of verbs related to movement or administration. It also frequently serves as an attributive (a word that modifies another noun) to describe things related to the port or border.

Common Verb Pairings: Common verbs include '经过' (to pass through), '开放' (to open), '管理' (to manage), and '关闭' (to close).

When you want to say you are crossing a border, you would say '经过口岸' (passing through the port). For example, '我们从罗湖口岸进入深圳' (We entered Shenzhen through the Luohu Port). Here, 'Luohu' is the specific name of the crossing, and '口岸' defines its status as an official gateway.

政府决定增加新的陆路口岸。(The government decided to add new land ports.)

As an attributive, it forms compound nouns that are essential for travelers and business people. '口岸手续' (port procedures) refers to the paperwork required to clear customs. '口岸城市' (port city) refers to a city whose economy or identity is defined by its role as a gateway. Unlike '港口城市' (harbor city), which implies a city with a physical dock, a '口岸城市' could be a city in the middle of a desert that sits on a major international railway line.

In academic or journalistic writing, you will see the structure '口岸+Noun' very often. '口岸经济' (port economy) and '口岸建设' (port construction) are common. If you are writing a report about trade, these are the terms you must use to sound professional.

请在离开口岸前检查您的证件。(Please check your documents before leaving the port.)

Sentence Structure: [Subject] + [Preposition: 经/从] + [Name of Port] + 口岸 + [Verb: 进入/离开] + [Destination].

Furthermore, in the context of the COVID-19 pandemic, the term '口岸防疫' (port epidemic prevention) became a daily term in Chinese news, referring to the strict health checks at borders. This shows how the word adapts to current events while maintaining its core meaning of a 'controlled gateway.'

You are most likely to hear 口岸 (kǒu'àn) in environments where international movement is managed. If you are standing in an international airport in Beijing, Shanghai, or Guangzhou, the public address announcements regarding customs and immigration will frequently use this word. It is the language of authority and organization.

Location 1: Border Crossings: Signs at the border between Mainland China and Hong Kong or Macau, such as '罗湖口岸' (Luohu Port) or '拱北口岸' (Gongbei Port).

In the news, specifically business and political news, '口岸' is a staple. News anchors will report on '口岸贸易额' (port trade volume) or '口岸通关时间缩短' (shortened port clearance time). When China announces new 'Free Trade Zones,' the discussion always centers on the efficiency of the local 口岸. It is a word associated with progress, efficiency, and international openness.

播音员：'各位旅客，欢迎来到上海浦东国际机场口岸。' (Announcer: 'Dear passengers, welcome to the Shanghai Pudong International Airport Port.')

Logistics professionals and freight forwarders use this word daily. If you are tracking a package from overseas, the status might update to '到达口岸' (arrived at the port). This doesn't necessarily mean it's on a ship; it could be at an air cargo terminal. For these professionals, the 口岸 is the bottleneck or the gateway that determines their success.

Location 2: Government Documents: Visa application forms, customs declaration cards, and official travel advisories.

In films or documentaries about modern China, particularly those focusing on trade or the history of cities like Hong Kong, the term serves as a bridge between the local and the global. It evokes images of busy docks, scanning machines, and the flow of people carrying suitcases across a line. It is a word of movement.

新闻：'今年该口岸的出入境人数创下新高。' (News: 'The number of people entering and exiting through this port reached a new high this year.')

One of the most common mistakes learners make is confusing 口岸 (kǒu'àn) with 港口 (gǎngkǒu). While both involve water in their literal components, their usage in modern Chinese is very different. 港口 refers specifically to a harbor or a sea port where ships dock. 口岸 is an administrative term for any international crossing.

Mistake 1: Using '口岸' for a local fishing dock: If you are talking about a small place where local fishermen park their boats, use '码头' (mǎtóu) or '港口'. '口岸' implies international customs control.

Another mistake is thinking 口岸 only refers to sea travel. Because of the character '岸' (shore), many students assume it must involve water. However, a land border between China and Vietnam is a 口岸, and the Beijing Capital International Airport is also a 口岸. If there is a customs check for international travel, it is a 口岸.

Wrong: 我去机场的港口。(I go to the harbor of the airport.)
Right: 我去机场口岸办理手续。(I go to the airport port to handle procedures.)

Learners also sometimes confuse 口岸 with 海关 (hǎiguān - Customs). '海关' is the agency or the government department (the people in uniform), while 口岸 is the physical/administrative location where that agency operates. You pass through a 口岸, and you are inspected by the 海关.

Mistake 2: Confusing with '边界' (biānjiè): '边界' is the entire border line between two countries. '口岸' is the specific point where you are legally allowed to cross that line.

Finally, remember that 口岸 is a formal term. In a diary entry about a fun trip, you might just say '过关' (guòguān - to cross the pass/customs), but in a travel guide or a business email, 口岸 is the expected term.

To truly master 口岸 (kǒu'àn), you should understand how it relates to other words in the 'travel and transport' semantic field. Depending on the nuance you want to convey, there are several alternatives.

港口 (gǎngkǒu): Refers to a harbor or a commercial port specifically for ships. Use this when discussing the physical infrastructure, cranes, and docks. Example: 上海港是世界上最繁忙的港口之一。
关口 (guānkǒu): Often refers to a strategic pass or a checkpoint. While similar to '口岸', it is more common in historical or metaphorical contexts (like 'a critical juncture'). Example: 这是一个重要的历史关口。
码头 (mǎtóu): A pier, wharf, or dock. This is much smaller and more specific than '口岸'. You wait for a ferry at a '码头', but you clear international customs at a '口岸'.

For land crossings specifically, you might hear 边境站 (biānjìng zhàn - border station). This is more descriptive of the physical building at a land border. 口岸 remains the more formal, administrative umbrella term that includes the station, the customs area, and the legal status of the crossing.

比较：这个口岸（行政概念）有很多个码头（物理设施）。(Comparison: This port [administrative concept] has many piers [physical facilities].)

When discussing airports, '口岸' is used in phrases like '航空口岸' (aviation port). While you wouldn't call an airport a '港口' (harbor), calling it a '口岸' is perfectly correct in a legal or trade context. This versatility is what makes 口岸 a powerful word in professional Chinese.

In some informal contexts, people just say '关' (guān), as in '过关' (to go through the pass). This is a very common spoken shorthand for passing through a 口岸. However, you would never see '关' used as a standalone noun in a formal report where '口岸' is required.

How Formal Is It?

豆知識

In ancient China, '口' was often used to describe strategic passes in the Great Wall (like Shanhaiguan), while '岸' was for water. The combination '口岸' evolved as China opened to maritime trade.

発音ガイド

UK /kʰoʊ̯˨˩˦ a̠n˥˩/

US /koʊ̯˨˩˦ an˥˩/

In Chinese, both syllables carry their own tone stress, but 'àn' often feels more emphatic due to the 4th tone's nature.

よくある間違い

Pronouncing 'àn' as 'ān' (1st tone) instead of 'àn' (4th tone).
Failing to dip low enough on the 3rd tone 'kǒu'.
Confusing 'àn' with 'àng' (adding a nasal 'ng' sound).
Slurring the two syllables together so they sound like 'kwàn'.
Pronouncing 'kǒu' like the English word 'cow'.

Formal Documents

Always check if a document asks for your '入境口岸' (Port of Entry). This is where you write the name of the airport or crossing.

Land vs Sea

Use '陆路口岸' for land crossings and '水运口岸' for sea ports to be more precise.

The Mouth Metaphor

Remembering that '口' means mouth helps you realize the port is where the country 'eats' imports and 'breathes' trade.

チャレンジ

語源

The word is composed of two ancient Chinese characters. '口' (kǒu) originally depicted a human mouth and came to mean an opening or entrance. '岸' (àn) originally referred to the high bank of a river or a shore.

元の意味： A river mouth or a point on a shore used for docking and transit.

文化的な背景

Always refer to ports between Mainland China and Hong Kong/Macau as '口岸' rather than 'international borders' to reflect the 'One Country, Two Systems' policy.

In English, we use different words for 'airport,' 'harbor,' and 'border crossing.' Chinese uses '口岸' to unify all these under one administrative concept.

The Luohu Port (罗湖口岸) - One of the busiest land crossings in the world. The Silk Road land ports like Alashankou. The 'Treaty Ports' (通商口岸) mentioned in history books.

No. Despite the character '岸' (shore), it refers to any international point of entry, including airports and land border crossings.

港口 (gǎngkǒu) is the physical harbor for ships. 口岸 (kǒu'àn) is the administrative term for a place where you clear customs. An airport is a 口岸 but not a 港口.

You can say '过口岸' (guò kǒu'àn) or more formally '经过口岸' (jīngguò kǒu'àn).

Yes, it is a relatively formal term. In very casual speech, people might just say '海关' (Customs) or '关' (the pass).

These are ports approved by the State Council that are open to foreign nationals and vessels.

Usually no. '口岸' implies international or special-region (like HK/Macau) travel involving customs.

You can use '个' (gè) for general use or '处' (chù) for a more formal tone.

It means 'port customs clearance,' the process of getting goods or people through the port legally.

Only if it handles international flights. A domestic-only airport is not a '口岸'.

Because the port is seen as the 'mouth' or 'opening' of the country to the outside world.
