The Chinese number system is logical once you see the pattern. Learn how to count, say dates and times, and handle large numbers like 10,000 and beyond.
Chinese numbers are one of the first topics most learners cover, and for good reason: the core system is genuinely simple. Unlike European languages, where numbers follow irregular patterns (English has "eleven" and "twelve" rather than "ten-one" and "ten-two"; French has soixante-dix, literally "sixty-ten", for seventy), Mandarin Chinese numbers are almost completely regular. Once you know one through ten, you can generate any number up into the hundreds using transparent arithmetic logic.
That said, there are a handful of areas where Chinese numbers diverge from what English speakers expect — particularly around large numbers, the special number two, dates, phone numbers, and certain cultural conventions around specific digits. Understanding these quirks fully prevents the persistent low-level errors that even intermediate learners make when dealing with numbers in real contexts.
The first ten numbers in Mandarin are: 一 (yī, one), 二 (èr, two), 三 (sān, three), 四 (sì, four), 五 (wǔ, five), 六 (liù, six), 七 (qī, seven), 八 (bā, eight), 九 (jiǔ, nine), 十 (shí, ten).
These must be memorised — there is no shortcut. But there are only ten of them, and most learners have them solid within the first week of study. The characters are among the most common in written Chinese and appear constantly in everyday contexts, so reinforcement through natural reading happens quickly.
One pronunciation note for beginners: 一 (yī) changes tone depending on the tone of the word that follows it. This is a tone sandhi rule — before a fourth tone word, 一 becomes second tone (yí); before any other tone, 一 becomes fourth tone (yì). In practice, learners absorb this naturally through exposure, but knowing the rule helps when you encounter it explicitly.
This is where Chinese arithmetic transparency becomes apparent. Numbers from eleven to ninety-nine are constructed by combining tens and units in exactly the order you would say them in arithmetic:
十一 (shíyī) = ten-one = eleven. 二十 (èrshí) = two-ten = twenty. 二十八 (èrshí bā) = two-ten-eight = twenty-eight. 九十九 (jiǔshíjiǔ) = nine-ten-nine = ninety-nine.
There are no irregular forms, no special words for eleven, twelve, thirteen, or any of the teens. This regularity means that learners can produce and understand any two-digit number almost immediately after learning the first ten. Studies comparing mathematical learning across cultures have found that children learning to count in Chinese make fewer errors at this stage because the naming system maps directly to place value — a pedagogical advantage that happens to benefit adult language learners too.
The hundreds follow the same logic: 一百 (yībǎi) = one hundred, 二百 (èrbǎi) = two hundred, through 九百 (jiǔbǎi) = nine hundred.
Thousands: 一千 (yīqiān) = one thousand, 二千 (èrqiān) = two thousand, and so on.
Here is the first important difference from English: where English uses a three-digit grouping (thousands, millions, billions), Chinese uses a four-digit grouping. The key unit is 万 (wàn), meaning ten thousand. Numbers in Chinese are naturally chunked as follows:
一万 = 10,000 (ten thousand). 十万 = 100,000 (one hundred thousand). 一百万 = 1,000,000 (one million). 一千万 = 10,000,000 (ten million). 一亿 (yī yì) = 100,000,000 (one hundred million).
This four-digit grouping trips up English speakers consistently when dealing with large numbers in Chinese. When you hear 三百万 (sānbǎi wàn), you need to calculate 300 x 10,000 = 3,000,000 (three million). When you hear 两千五百亿 (liǎngqiān wǔbǎi yì), you need to calculate 2,500 x 100,000,000 = 250,000,000,000 (two hundred and fifty billion).
The best way to build fluency with large numbers is to practice converting between the Chinese four-digit grouping and English three-digit grouping deliberately, until the conversion becomes automatic. Business contexts, news consumption, and financial discussions in Chinese all require this fluency.
Chinese has two words that both mean "two" — 二 (èr) and 两 (liǎng) — and knowing when to use each is one of the small hurdles that every learner faces.
As a general rule: 二 is used for counting and in compound numbers (二十 = twenty, 第二 = second). 两 is used when the number two precedes a measure word (两个人 = two people, 两杯水 = two glasses of water, 两百 = two hundred). For large round numbers, 两 is also typically used: 两千 (two thousand), 两万 (twenty thousand).
The distinction is not random — it maps roughly to the difference between the number two as an abstract concept (二) and the number two as a counting quantity applied to real things (两). But learners are better off treating it as a convention to absorb through practice rather than a rule to apply analytically in real time. Native speakers correct this gently and consistently, so the feedback loop during practice is natural and fast.
Chinese dates follow the logical largest-to-smallest order: year, month, day — the opposite of the American MM/DD/YYYY format and the same order as the ISO standard YYYY/MM/DD.
The year is read as individual digits: 2025 is 二零二五年 (èr líng èr wǔ nián), literally "two zero two five year." Note 零 (líng) for zero — this is also the character used when there is a zero placeholder in other number contexts (one hundred and five = 一百零五, literally "one hundred zero five").
Months use the simple pattern of number + 月 (yuè, month): 一月 (January), 二月 (February), through 十二月 (December). No special month names. Days use number + 号 (hào, number/day) in spoken language or + 日 (rì) in formal written language: 十五号 or 十五日 = the fifteenth.
A full date: 二零二五年九月十五日 = September 15th, 2025. Spoken: 二零二五年九月十五号.
Days of the week follow two possible patterns. The most common: 星期 (xīngqī) or 周 (zhōu) followed by a number one through six (Monday to Saturday), with 星期日 or 星期天 for Sunday. So Monday = 星期一, Tuesday = 星期二, through Saturday = 星期六, Sunday = 星期日 or 星期天.
Time of day: hours use + 点 (diǎn, o'clock), half hours + 点半 (half past), minutes + 分 (fēn). 八点半 = eight thirty. 下午三点二十分 = 3:20 pm.
Phone numbers, ID numbers, room numbers, and similar digit strings in Chinese are typically read as individual digits, not as a number in the arithmetic sense. The exception is that 一 (yī) in phone numbers is often replaced by 幺 (yāo) to avoid confusion with 七 (qī, seven) on a phone line — both can sound similar in noisy conditions or over the telephone.
So a phone number like 13812345678 would be read as: 幺三八幺二三四五六七八, not as one hundred thirty-eight trillion something. This distinction between reading digits and reading numbers is intuitive in practice but worth being aware of explicitly.
Chinese currency has two register systems. The formal name for the currency is 人民币 (Rénmínbì, People's Currency), abbreviated RMB. The unit name used in formal contexts is 元 (yuán). In spoken language, the unit is universally 块 (kuài, literally "chunk" or "piece"). Fractions use 角 (jiǎo, formal) or 毛 (máo, spoken) for 0.1 yuan, and 分 (fēn) for 0.01 yuan — though prices below one jiao/mao are essentially extinct in modern China.
Prices in spoken Chinese: 三十五块钱 (sānshíwǔ kuài qián) = thirty-five yuan. 一百二十块 (yī bǎi èrshí kuài) = one hundred and twenty yuan. 两块五 (liǎng kuài wǔ) = two yuan fifty (with 毛 omitted at the end, which is common in casual speech).
Number associations in Chinese culture are worth knowing, not because they affect grammar or pronunciation, but because they affect real behavior in ways that come up constantly in everyday life.
Eight (八, bā) is the luckiest number in Chinese culture, because its pronunciation resembles 发 (fā), meaning to prosper or become wealthy. Phone numbers, addresses, and license plates containing multiple eights command significant premiums. The 2008 Beijing Olympics opening ceremony began at 8:08:08 pm on 8/8/2008 deliberately.
Four (四, sì) is considered unlucky because it sounds like 死 (sǐ), meaning death. Many buildings in China skip floor four entirely, and some skip any floor containing four — fourth, fourteenth, twenty-fourth, forty-fourth, and so on. This is similar to the phenomenon in Western buildings that skip the thirteenth floor, but more widespread and more deeply embedded in everyday decision-making.
Six (六, liù) is associated with smooth progress (六六大顺, everything goes smoothly). Seven (七, qī) has various associations but is generally neutral. Nine (九, jiǔ) sounds like 久 (jiǔ, long-lasting), making it associated with longevity and permanence — hence common use in wedding contexts.
Once you have the system solid, encountering numbers in authentic Chinese text becomes a reading comprehension opportunity rather than an obstacle. News articles, stories, and everyday texts are full of numbers — dates, ages, prices, distances, statistics — and each encounter reinforces the system.
The Trip to the Market story at HSK 3 is an ideal story for encountering numbers in authentic context — prices, quantities, and bargaining conversations all feature naturally. The My Favourite Rice Cooker story at HSK 4 is another example where real-world numerical language appears in a natural narrative context.
The Grammar section covers measure words, which are closely tied to the number system — every time you count something in Chinese, a measure word sits between the number and the noun, and knowing the right measure word requires knowing the categories Chinese uses to classify objects.
