Formal vs. Informal Chinese: Words Advanced Learners Need to Recognize

Why Advanced Chinese Requires More Than Knowing Vocabulary

At beginner and intermediate levels, Chinese learners often focus on whether a word is correct or incorrect. However, at HSK 7–9 level, vocabulary is not only about meaning. It is also about register, social context, and communication style.

A Chinese word can be grammatically correct but still sound inappropriate because it belongs to a different social situation. A phrase that works perfectly in a conversation with friends may sound too casual in a newspaper article, academic paper, business meeting, or official announcement.

Chinese has a clear distinction between formal language (正式用语, zhèng shì yòng yǔ) and informal language (口语, kǒu yǔ). Advanced students must recognize both because modern Chinese communication constantly moves between different styles.

For example, a person might say:

“我们聊一下这个问题。”
(wǒ men liáo yí xià zhè ge wèn tí)
“Let’s talk about this issue.”

This sounds natural in everyday conversation.

However, in a formal report, the same idea may appear as:

“我们将对这一问题进行探讨。”
(wǒ men jiāng duì zhè yī wèn tí jìn xíng tàn tǎo)
“We will conduct an exploration of this issue.”

Both sentences express a similar meaning, but the second one belongs to formal written Chinese.

Understanding this difference is essential for reading Chinese newspapers, academic articles, government documents, business reports, and serious literature.

The Relationship Between Formal and Informal Chinese

Chinese does not have a simple division between “spoken words” and “written words.” Many formal words are commonly used in speech, especially among educated speakers, while many informal expressions appear in online writing.

The difference is usually related to:

• Situation
• Relationship between speakers
• Purpose of communication
• Level of respect
• Degree of professionalism

For example, when introducing someone:

“这是我的朋友。”
(zhè shì wǒ de péng yǒu)
“This is my friend.”

This is a normal everyday expression.

In a formal introduction, someone might say:

“这位是我的好友。”
(zhè wèi shì wǒ de hǎo yǒu)
“This is my close friend.”

Or:

“这位是我的合作伙伴。”
(zhè wèi shì wǒ de hé zuò huǒ bàn)
“This is my business partner.”

The vocabulary choice reveals the relationship and the situation.

Common Informal Words and Their Formal Alternatives

Many HSK 7–9 words are difficult because advanced texts often replace simple everyday vocabulary with more formal expressions.

For example:

“开始” (kāi shǐ) means “to begin.”

In everyday speech:

“会议开始了。”
(huì yì kāi shǐ le)
“The meeting has started.”

In formal writing:

“会议正式启动。”
(huì yì zhèng shì qǐ dòng)
“The meeting has officially commenced.”

The word 启动 (qǐ dòng) is more formal and often appears in news reports, government documents, and business contexts.

Another example:

“买” (mǎi) means “to buy.”

Everyday:

“我想买一本书。”
(wǒ xiǎng mǎi yì běn shū)
“I want to buy a book.”

Formal:

“购买” (gòu mǎi) is often used in official or written contexts.

Example sentences:

公司计划购买新的设备。(gōng sī jì huá gòu mǎi xīn de shè bèi)- The company plans to purchase new equipment.
我昨天买了一件衣服。(wǒ zuó tiān mǎi le yí jiàn yī fu)- I bought a piece of clothing yesterday.

The meaning is almost identical, but the feeling is different.

Formal Vocabulary in Newspapers and Official Chinese

HSK 7–9 students will frequently encounter formal vocabulary in Chinese news articles.

A newspaper usually does not write:

“很多人觉得这个政策不好。”

(hěn duō rén jué de zhè ge zhèng cè bù hǎo)

“Many people think this policy is bad.”

Instead, it may write:

“部分人士认为该政策存在不足。”

(bù fèn rén shì rèn wéi gāi zhèng cè cún zài bù zú)

“Some people believe that this policy has shortcomings.”

Several formal words appear here:

部分 (bù fèn)- some, part of
人士 (rén shì)- persons, individuals
认为 (rèn wéi)- to believe, consider
该 (gāi)- this, said (formal reference)
存在 (cún zài)- to exist
不足 (bù zú)- shortcomings

These words are extremely common in advanced Chinese reading.

Example sentences:

许多专家认为，该技术具有广阔的发展前景。(xǔ duō zhuān jiā rèn wéi, gāi jì shù jù yǒu guǎng kuò de fā zhǎn qián jǐng)- Many experts believe that this technology has broad development prospects.
该项目已经取得明显成果。(gāi xiàng mù yǐ jīng qǔ dé míng xiǎn chéng guǒ)- This project has already achieved significant results.

Formal Chinese in Business Communication

Business Chinese relies heavily on formal vocabulary. A casual phrase can sound unprofessional in a workplace setting.

For example:

Informal:

“告诉我你的想法。”

(gào sù wǒ nǐ de xiǎng fǎ)

“Tell me your thoughts.”

Formal:

“请提出您的意见。”

(qǐng tí chū nín de yì jiàn)

“Please provide your opinions.”

The word 提出 (tí chū) means “to put forward” and is frequently used in formal discussions.

Another example:

Informal:

“我们需要解决这个问题。”

(wǒ men xū yào jiě jué zhè ge wèn tí)

“We need to solve this problem.”

Formal:

“我们需要采取措施解决这一问题。”

(wǒ men xū yào cǎi qǔ cuò shī jiě jué zhè yī wèn tí)

“We need to take measures to solve this issue.”

采取措施 (cǎi qǔ cuò shī) is a common formal phrase meaning “take measures.”

Example sentences:

政府采取措施改善环境。(zhèng fǔ cǎi qǔ cuò shī gǎi shàn huán jìng)- The government takes measures to improve the environment.
企业正在寻找有效的方法降低成本。(qǐ yè zhèng zài xún zhǎo yǒu xiào de fāng fǎ jiàng dī chéng běn)- Companies are searching for effective methods to reduce costs.

Chinese Words That Change According to Social Distance

Chinese communication often reflects social relationships.

A close friend might say:

“你吃饭了吗？”

(nǐ chī fàn le ma)

“Have you eaten?”

This is a very common informal greeting.

However, in a formal situation, people may say:

“您好，最近身体怎么样？”

(nín hǎo, zuì jìn shēn tǐ zěn me yàng)

“Hello, how have you been recently?”

The use of 您 (nín) instead of 你 (nǐ) shows respect.

Similarly:

Informal:

“帮我看看。”

(bāng wǒ kàn kan)

“Help me take a look.”

Formal:

“麻烦您查看一下。”

(má fan nín chá kàn yí xià)

“Could you please check it?”

查看 (chá kàn) is more formal than 看 (kàn).

Formal Written Words from Classical Chinese

One reason advanced Chinese feels difficult is that many formal words come from Classical Chinese (文言文, wén yán wén).

Modern Chinese contains many expressions that preserve older linguistic patterns.

For example:

因为 (yīn wèi)- because

Formal:

由于 (yóu yú)- due to, because of

Example:

“由于天气原因，活动延期。”

(yóu yú tiān qì yuán yīn, huó dòng yán qī)

“Due to weather conditions, the event has been postponed.”

Another example:

但是 (dàn shì)- but

Formal:

然而 (rán ér)- however

Example sentences:

这个方法看起来简单，然而实际操作并不容易。(zhè ge fāng fǎ kàn qǐ lái jiǎn dān, rán ér shí jì cāo zuò bìng bù róng yì)- This method looks simple; however, actual operation is not easy.
虽然困难很多，但是我们仍然坚持。(suī rán kùn nan hěn duō, dàn shì wǒ men réng rán jiān chí)- Although there are many difficulties, we continue to persist.

Formal Chinese in Academic Writing

Academic Chinese has its own vocabulary style.

Instead of:

“这个研究说明……”

(zhè ge yán jiū shuō míng)

“This research says…”

Academic writing often uses:

“该研究表明……”

(gāi yán jiū biǎo míng)

“This study demonstrates…”

Important academic words include:

研究 (yán jiū)- research
表明 (biǎo míng)- demonstrate, indicate
分析 (fēn xī)- analyze
探讨 (tàn tǎo)- explore
影响 (yǐng xiǎng)- influence
因素 (yīn sù)- factor

Example sentences:

本文分析了中国社会发展的主要因素。(běn wén fēn xī le zhōng guó shè huì fā zhǎn de zhǔ yào yīn sù)- This article analyzes the main factors behind Chinese social development.
研究结果表明，语言环境对学习效果具有重要影响。(yán jiū jié guǒ biǎo míng, yǔ yán huán jìng duì xué xí xiào guǒ jù yǒu zhòng yào yǐng xiǎng)- Research results show that the language environment has an important influence on learning outcomes.
