Chinese Negation: How to Say “No” and “Not” in Mandarin (不 vs 没)

Saying “no” and “not” in Chinese isn’t as simple as in English. Chinese has two main negation words—不 (bù) and 没 (méi)—and choosing the wrong one is one of the most common mistakes learners make!

Don’t worry—this guide will teach you exactly when to use each negation word, covering all the patterns you need to know. By the end, you’ll negate like a native! 🎯

The Two Main Negation Words

不 (bù) – General Negation

Pronunciation Note: 不 is normally fourth tone (bù), but changes to second tone (bú) before another fourth tone word.

Examples:

• 不去 (bú qù) – not go
• 不是 (bú shì) – is not
• 不好 (bù hǎo) – not good

没 (méi) – Absence/Non-completion

Full form: 没有 (méiyǒu) – often shortened to 没 (méi)

Examples:

• 没去 (méi qù) – didn’t go
• 没有 (méiyǒu) – don’t have
• 没钱 (méi qián) – no money

不 (bù) – When and How to Use It

Before diving into the grammar foundation, make sure you understand basic sentence structure. Check out my guide to Chinese sentence structure for context.

Use 不 for:

1. Habitual Actions (Present Tense)

Formula: Subject + 不 + Verb

Examples:

2. Future Actions

Examples:

• 我明天不去。(I won’t go tomorrow.)
• 他下周不来。(He won’t come next week.)
• 我们今晚不吃饭。(We won’t eat tonight.)

3. Willingness or Ability (with Modal Verbs)

Examples:

• 我不会说中文。(I can’t speak Chinese.)
• 他不想去。(He doesn’t want to go.)
• 她不能来。(She can’t come.)
• 我不要！(I don’t want it!)

4. Adjectives and 是

Examples:

• 这个不好。(This isn’t good.)
• 天气不冷。(The weather isn’t cold.)
• 我不是学生。(I’m not a student.)
• 这不对。(This isn’t right.)

Key Point: Always use 不 with 是, never 没!

没 (méi) / 没有 (méiyǒu) – When and How to Use It

Use 没 for:

1. Negating Completed Actions (like 了)

Formula: Subject + 没(有) + Verb

Examples:

Important: When using 没, drop the 了!

2. Negating 过 (Experience)

Examples:

• 我没去过中国。(I’ve never been to China.)
• 他没吃过北京烤鸭。(He’s never eaten Peking duck.)
• 我没见过她。(I’ve never met her.)

3. Possession (有 → 没有)

Full form 没有 is required here!

Examples:

4. Comparisons (as … as)

Pattern: A + 没有 + B + (这么/那么) + Adjective

Examples:

• 今天没有昨天冷。(Today isn’t as cold as yesterday.)
• 他没有我高。(He isn’t as tall as me.)
• 这个没有那个好。(This isn’t as good as that.)

不 vs 没 – Direct Comparison

Same Sentence, Different Meaning!

Using 不 vs 没 can completely change the meaning:

Special Negation Words

别 (bié) – Don’t! (Negative Imperative)

Function: Negative commands, telling someone NOT to do something

Formula: 别 + Verb

Examples:

• 别走！(Don’t go!)
• 别说了！(Stop talking!)
• 别担心。(Don’t worry.)
• 别忘了！(Don’t forget!)

Note: 别 is softer than 不要. For stronger commands, use 不要 or 不许.

未 (wèi) – Not Yet (Literary/Formal)

Function: More formal version of 没, used in written/formal Chinese

Examples:

• 未来 (wèilái – future, literally “not yet come”)
• 未知 (wèizhī – unknown)
• 前途未卜 (uncertain future)

In conversation, use 没 instead of 未.

无 (wú) – Without/No (Literary/Formal)

Function: Literary negation, common in set phrases and formal writing

Examples:

• 无聊 (wúliáo – boring, “without interest”)
• 无论 (wúlùn – no matter, regardless)
• 无法 (wúfǎ – unable to, “no method”)
• 无数 (wúshù – countless)

Common Negative Patterns

1. Neither…Nor… (既不…也不…)

Pattern: 既不 + A + 也不 + B

Examples:

• 我既不喝咖啡也不喝茶。(I drink neither coffee nor tea.)
• 他既不高也不矮。(He’s neither tall nor short.)

2. Not…But… (不是…而是…)

Pattern: 不是 + A + 而是 + B

Examples:

• 这不是我的而是他的。(This isn’t mine but his.)
• 他不是老师而是学生。(He’s not a teacher but a student.)

3. Not Only…But Also… (不但…而且…)

Pattern: 不但 + A + 而且 + B

Examples:

• 他不但会说中文，而且会说日语。(He not only speaks Chinese but also Japanese.)
• 这个不但便宜而且好。(This is not only cheap but also good.)

4. Not As Good As (不如)

Pattern: A + 不如 + B

Examples:

• 我不如他聪明。(I’m not as smart as him.)
• 这个不如那个好。(This isn’t as good as that.)
• 今天不如昨天热。(Today isn’t as hot as yesterday.)

5. Cannot Help But… (不得不)

Pattern: Subject + 不得不 + Verb

Examples:

• 我不得不去。(I have no choice but to go.)
• 他不得不承认。(He had to admit it.)

Double Negatives in Chinese

Chinese uses double negatives for emphasis (unlike English where they cancel out).

不会不… (must/definitely will)

Examples:

• 他不会不来的。(He definitely will come.)
• 我不会不知道。(I definitely know.)

不是不… (it’s not that…)

Examples:

• 我不是不想去，只是没时间。(It’s not that I don’t want to go, I just don’t have time.)
• 他不是不聪明，只是懒。(It’s not that he’s not smart, he’s just lazy.)

没有…不… (there’s nothing that doesn’t…)

Examples:

• 没有人不喜欢他。(Everyone likes him.)
• 没有什么不可能。(Nothing is impossible.)

• Think: “I DON’T do this” (general statement)

没 (méi) = Absence/Didn’t happen

• Use for completed actions, possession, past
• Think: “It DIDN’T happen” or “I DON’T HAVE”

别 (bié) = Don’t!

• Use for commands only
• Think: “DON’T do that!”
