Chinese Numbers 1-10
The numbers 1-10 are the building blocks of the entire Chinese number system. Each has a single character and a single syllable with a specific tone. Mandarin Chinese has four tones plus a neutral tone, and mastering them is essential.
Tone Fundamentals
The syllable "si" with a falling tone (fourth tone) means four. That same syllable with a rising tone (third tone) means death. This tonal distinction is why the number 4 is considered so unlucky in Chinese culture.
Mastering Each Number
Each of these ten core numbers will be your foundation. Pay close attention to the tone marks and phonetic descriptions as you practice.
- 一 (yi) - one - "ee" (high flat tone)
- 二 (er) - two - "ar" (falling tone)
- 三 (san) - three - "sahn" (high flat tone)
- 四 (si) - four - "suh" (falling tone)
- 五 (wu) - five - "woo" (dipping tone)
- 六 (liu) - six - "lyoh" (falling tone)
- 七 (qi) - seven - "chee" (high flat tone)
- 八 (ba) - eight - "bah" (high flat tone)
- 九 (jiu) - nine - "jyoh" (dipping tone)
- 十 (shi) - ten - "shuh" (rising tone)
| Term | Meaning | Pronunciation | Example |

Chinese Numbers 11-20
Numbers 11-19 follow an elegant pattern: ten plus digit. There are no irregular forms to memorize. Eleven is literally "ten-one" (shi yi), twelve is "ten-two" (shi er), and so on. Twenty is "two-ten" (er shi).
The Pattern Explained
This logical structure continues all the way to 99. Once you understand this pattern, you can construct any number from 11 to 99 without memorization.
Practical Numbers for Daily Use
These numbers appear frequently in real-world contexts like telling time, counting ages, and stating dates. Practice them until the pattern becomes automatic.
- 十一 (shi yi) - "shuh ee"
- 十二 (shi er) - "shuh ar"
- 十三 (shi san) - "shuh sahn"
- 十四 (shi si) - "shuh suh"
- 十五 (shi wu) - "shuh woo"
- 十六 (shi liu) - "shuh lyoh"
- 十七 (shi qi) - "shuh chee"
- 十八 (shi ba) - "shuh bah"
- 十九 (shi jiu) - "shuh jyoh"
- 二十 (er shi) - "ar shuh"
| Term | Meaning | Pronunciation | Example |
|---|---|---|---|
| 十一 (shi yi) | eleven (11) | shuh ee | 十一月很冷。Shiyi yue hen leng. (November is very cold.) |
| 十二 (shi er) | twelve (12) | shuh ar | 十二点吃午饭。Shi'er dian chi wufan. (Eat lunch at twelve.) |

| 二十 (er shi) | twenty (20) | ar shuh | 二十块太贵了。Ershi kuai tai gui le. (Twenty yuan is too expensive.) |
Tens and Patterns to 100
The pattern for tens is straightforward: the multiplier plus 十 (shi). Thirty is 三十 (san shi, three-ten), forty is 四十 (si shi, four-ten), and so on through ninety.
Building Compound Numbers
For any number between tens, simply add the ones digit after the tens value. The number 35 is 三十五 (san shi wu, three-ten-five). This system works consistently for all numbers up to 99.
Reaching 100
One hundred is 一百 (yi bai). After this, the same additive principle applies for numbers like 101 (一百零一), 125 (一百二十五), and beyond.
- 三十 (san shi) - "sahn shuh"
- 四十 (si shi) - "suh shuh"
- 五十 (wu shi) - "woo shuh"
- 六十 (liu shi) - "lyoh shuh"
- 七十 (qi shi) - "chee shuh"
- 八十 (ba shi) - "bah shuh"
- 九十 (jiu shi) - "jyoh shuh"
- 一百 (yi bai) - "ee by"
| Term | Meaning | Pronunciation | Example |
|---|---|---|---|
| 三十 (san shi) | thirty (30) | sahn shuh | 三十分钟到。Sanshi fenzhong dao. (Arrive in thirty minutes.) |
| 四十 (si shi) | forty (40) | suh shuh | 他四十岁了。Ta sishi sui le. (He is forty years old.) |

Lucky and Unlucky Numbers in Chinese Culture
Number symbolism plays a massive role in Chinese culture, influencing everything from wedding dates to phone numbers to real estate prices. Lucky numbers command premium prices. A phone number with many 8s can sell for thousands of dollars. Buildings routinely skip floors with 4 in them.
Why Homophones Matter
These superstitions are rooted in homophones, words that sound identical or nearly identical. The cultural impact is far more than folklore. It actively shapes pricing, real estate, and business decisions across Chinese-speaking societies worldwide.
Common Number Associations
Understanding these cultural meanings helps you communicate more effectively and appreciate Chinese traditions more deeply.
- 8 (ba) - Sounds like 发 (fa, prosperity). Considered extremely lucky.
- 6 (liu) - Sounds like 流 (liu, flow). Associated with smooth outcomes.
- 9 (jiu) - Sounds like 久 (jiu, longevity). Popular for long-term commitments.
- 4 (si) - Sounds like 死 (si, death). Considered very unlucky.
- 520 (wu er ling) - Sounds like "I love you." Internet slang for romance.
- 88 (ba ba) - Sounds like "bye bye." Used to say goodbye online.
| Term | Meaning | Pronunciation | Example |
|---|---|---|---|
| 八 (ba), Lucky | 8 sounds like 发 (fa, prosperity/wealth) | bah | The Beijing Olympics began at 8:08 PM on 08/08/08. Phone numbers with 8s are sold at a premium. |
| 六 (liu), Lucky | 6 sounds like 流 (liu, flow/smooth) | lyoh | 六六大顺 (liuliu dashun) means 'everything goes smoothly.' Popular for weddings and business openings. |
| 九 (jiu), Lucky | 9 sounds like 久 (jiu, longevity/forever) | jyoh | 九 is associated with the Emperor and long-lasting relationships. Popular for wedding dates. |
| 四 (si), Unlucky | 4 sounds like 死 (si, death) | suh | Many buildings skip floors 4, 14, 24, etc. License plates with 4 are avoided. |
| 五二零 (wu er ling) | 520 sounds like 我爱你 (wo ai ni, I love you) | woo ar ling | May 20th (5/20) is an unofficial Valentine's Day in China. 520 is texted like 'ILY.' |
| 八八 (ba ba) | 88 sounds like 'bye bye' in English | bah bah | Used as internet slang to say goodbye in Chinese chat messages and social media. |
How to Study Chinese Effectively
Mastering Chinese requires the right study approach, not just more hours. Research in cognitive science consistently shows that three techniques produce the best learning outcomes: active recall, spaced repetition, and interleaving.
The Three Pillars of Effective Learning
Active recall means testing yourself rather than re-reading. Spaced repetition involves reviewing at scientifically-optimized intervals. Interleaving means mixing related topics rather than studying one topic in isolation. FluentFlash is built around all three principles.
When you study Chinese numbers with the FSRS algorithm, every term is scheduled for review at exactly the moment you are about to forget it. This maximizes retention while minimizing study time.
Why Passive Review Fails
The most common mistake is relying on passive review methods. Re-reading your notes, highlighting textbook passages, or watching lecture videos feels productive. However, studies show these methods produce only 10-20% of the retention that active recall achieves. Flashcards force your brain to retrieve information, which strengthens memory pathways far more than recognition alone.
Your First Week Strategy
Create 15-25 flashcards covering the highest-priority concepts. Review them daily for the first week using spaced repetition scheduling. As cards become easier, intervals automatically expand from minutes to days to weeks. You are always working on material at the edge of your knowledge.
After 2-3 weeks of consistent practice, Chinese concepts become automatic rather than effortful to recall. This is when you know the material has moved into long-term memory.
- 1
Generate flashcards using FluentFlash AI or create them manually from your notes
- 2
Study 15-20 new cards per day, plus scheduled reviews
- 3
Use multiple study modes (flip, multiple choice, written) to strengthen recall
- 4
Track your progress and identify weak topics for focused review
- 5
Review consistently, daily practice beats marathon sessions
