Chinese numbers, from one hand to one billion

Hold up a thumb and an index finger in the shape of an L, and you have just said eight. Curl that index finger into a hook: nine. Two index fingers crossed in the air is ten, and you have used one hand the whole time.

Most learners meet these signs before they meet any grammar. You are in a market, someone quotes a price faster than you can parse it, and then a hand appears and solves the problem. Handy. But the hand is the easy half.

The hard half is structural, and it starts at ten thousand. English groups digits in threes: thousand, million, billion. Chinese groups them in fours, and it has no word that means million. That single difference is why you can count confidently to 999 in Chinese and still be lost the moment someone quotes a rent or a salary. It is also the reason this article exists, because character practice does not fix it. You have to rebuild how you hold large numbers in your head.

The hand signs, one to ten

Chinese hand signs run all the way to ten on one hand. English speakers run out at five, which is why the Chinese version looks like a party trick the first time you see it.

Number	Hand shape	Reading
1	Index finger up. Same as everywhere.	yī
2	Index and middle fingers, like a V.	èr
3	Thumb, index and middle. A bit like an OK sign, with the three fingers straight.	sān
4	Four fingers up, thumb folded in.	sì
5	The whole open hand.	wǔ
6	Thumb and little finger out. This is the shape English speakers use to mean "call me".	liù
7	Thumb, index and middle pinched together at the tips.	qī
8	Thumb and index out in an L, like a child's finger pistol.	bā
9	Index finger curled into a hook.	jiǔ
10	Two index fingers crossed. Some people make a fist instead.	shí

Two of these carry more weight than the rest. Six is the one Westerners misread, because that shape means "phone me" at home and six in China. Eight is worth drilling, because it is the hardest to produce by accident and it shows up constantly in prices, addresses and dates.

The signs are not decoration. In a loud restaurant, across a crowded platform, or mid-bargain when you would rather not commit to a pronunciation, a hand is faster than a sentence and much harder to mishear.

There are two words for two, and the choice is not free

This is the first rule that catches people who have counted to a hundred without any trouble at all.

The number two has two forms: 二 èr and 两 liǎng. They are not interchangeable. What decides it is what comes next.

The pattern underneath is simple once you can see it. 两 is what you say when a quantity is about to land on something countable. 二 is what you say inside the counting system itself, and after 十.

So 22 is 二十二 èr shí èr, both of them 二, because both are sitting inside a number rather than in front of a noun. But 200 is 两百 liǎng bǎi and 2,000 is 两千 liǎng qiān. February is 二月, never 两月, because months are a numbered list, not an amount of something.

One number is worth learning as vocabulary rather than arithmetic. 二百五 èr bǎi wǔ, literally two hundred and fifty, means a fool. The usual story is that half of 500 coins was a useless amount, and the label stuck to people who matched the description. Notice that the idiom keeps the 二 form. Nobody insults anyone by saying 两百五.

Zero is read once, and never at the end

Chinese has no "and" between places, and it never reads out more than one zero in a row.

Number	Chinese	Pinyin	Literal
105	一百零五	yī bǎi líng wǔ	one hundred zero five
150	一百五十	yī bǎi wǔ shí	one hundred five ten
1,005	一千零五	yī qiān líng wǔ	one thousand zero five
1,050	一千零五十	yī qiān líng wǔ shí	one thousand zero five ten
1,500	一千五百	yī qiān wǔ bǎi	one thousand five hundred
10,008	一万零八	yī wàn líng bā	one ten-thousand zero eight

The rule fits in one line: 零 is spoken once for a run of zeros, but only if a non-zero digit follows it. Zeros at the end of a number are never read. That is why 150 is 一百五十 with no 零 in sight, while 105 needs one.

Ten thousand is not "ten thousand". It is one 万.

Now the part that matters.

English builds large numbers from thousand, million and billion, stepping three digits at a time. Chinese steps four digits at a time, and the two units it uses are 万 and 亿. Neither one has an English equivalent you already own.

Value	English	Chinese	Pinyin
1,000	one thousand	一千	yī qiān
10,000	ten thousand	一万	yī wàn
100,000	one hundred thousand	十万	shí wàn
1,000,000	one million	一百万	yī bǎi wàn
10,000,000	ten million	一千万	yī qiān wàn
100,000,000	one hundred million	一亿	yī yì
1,000,000,000	one billion	十亿	shí yì
1,000,000,000,000	one trillion	一万亿	yī wàn yì

Read the middle rows again, slowly. One million is not a word in Chinese. It is 一百万, which is one hundred ten-thousands. A Chinese speaker who hears 1,000,000 does not reach for a unit called "million", because there is not one. They count the ten-thousands and get a hundred of them.

The same thing happens at 100,000,000. English needs three words to say it. Chinese has a single character, 亿 yì, and it appears the moment anyone discusses money, population or revenue.

Two consequences follow, and both are practical. First, a figure like 3,500,000 is not "three point five million" in a Chinese conversation. It is 三百五十万, three hundred and fifty ten-thousands. Second, the arithmetic gets easier once you stop converting. Put a comma every four digits from the right instead of every three, and the structure pops out. 123456789 becomes 1 2345 6789, which reads 一亿二千三百四十五万六千七百八十九 yī yì èr qiān sān bǎi sì shí wǔ wàn liù qiān qī bǎi bā shí jiǔ. Ugly to look at. Correct every time.

Where the textbook version stops helping

Numbers on a page and numbers in the street behave differently. Four places worth knowing about before you land.

Phone numbers

Digits are read one at a time rather than in hundreds and thousands, and 一 is normally read yāo instead of yī. The reason is practical: on a bad line, yī and qī (seven) are close enough to ruin an address. Numbers also get spoken in blocks. A Chinese mobile number is written 138 0013 8000 and read as three chunks, which is how people memorise them and why they will repeat a number back to you in pieces rather than as one long string.

Prices

Spoken prices drop the unit when it is obvious. 三块五 sān kuài wǔ is 3.50, with the second unit left off entirely. You will hear 块 far more often than the formal 元, and 毛 rather than 角 for the ten-cent units. Context does the rest.

Note that 2.50 is 两块五 liǎng kuài wǔ, not 二块五. Money is a quantity, and quantities take 两.

Floors and room numbers

Floors are an ordered list, so the second floor is 二楼 èr lóu, never 两楼. Room numbers are read digit by digit, so room 302 is 三零二 sān líng èr. Bus and metro lines follow the same digit-by-digit habit, which is why 一号线 and 二号线 sound like two short beats rather than a phrase.

Dates, months and years

Years are read digit by digit. 2026 is 二零二六年 èr líng èr liù nián, not "two thousand and twenty-six". Months are numbered with 二, so February is 二月. Days take 号 in speech rather than the written 日, so the third of the month is 三号.

Weekdays run on their own track: 星期一 through 星期六, with 星期日 or 星期天 for Sunday. Only the first six numbers appear, and 星期天 is the one people actually say.

What to learn first

You do not need the whole system in week one. Three things carry most of the weight:

• 一到十, spoken and on the hand. That covers prices, phone digits and most casual counting.
• 百 and 千, with the 两 rule attached. That gets you to 9,999, which is every shop price you will ever meet.
• 万. One character, and it carries everything above ten thousand, as long as you remember to count in fours.

亿 can wait. You will need it for news and business, not for ordering lunch.

Numbers are also one of the few parts of Chinese you can get fast at without a teacher, because there is a correct answer and you can check it yourself. Read a page of prices out loud, then verify. The Chinese numbers tool is built for exactly that: type any number up to a trillion, see it in characters, pinyin and the spoken form, and hear it read back. It also has the hand signs for one to ten and a printable practice sheet, which is more useful than it sounds, because numbers are the one thing you will need on paper in an exam, a form, or a bank counter.

Two related pieces if you want the background: the tones article covers why sì and shí are the two numbers foreigners mix up most, and the pinyin chart lets you click any syllable and hear all four tones before you commit one to memory.
