You’re standing in a bustling market in Chengdu or maybe just trying to read a menu in New York’s Chinatown. You see the symbols. They look like a series of elegant, minimalist sketches. At first glance, Chinese numerals 1 to 20 seem like a secret code, but honestly? It’s probably the most logical counting system ever devised by humans.
Chinese numbers aren't just about math. They’re a window into a culture that prizes efficiency and linguistic symmetry. If you can count to ten, you’ve basically mastered the entire foundational structure of the language. It’s that simple.
Most people overcomplicate it. They expect a "eleven" or a "twelve"—entirely new words that you have to memorize from scratch, like we do in English. But Chinese doesn't do that. It uses a "10 plus 1" logic that makes so much sense you’ll wonder why we don't all speak this way.
The Core Ten: Building Your Foundation
Let’s get the basics out of the way first. You can't build a house without bricks. In this case, the bricks are the characters for one through ten.
One is just a horizontal line: 一 (yī). Two is two lines: 二 (èr). Three is three lines: 三 (sān).
Easy, right? You’re basically a scholar already.
But then four (sì) throws a curveball. It’s a box with some legs inside: 四. This is where the cultural nuances kick in. You might have heard that people in China avoid the number four. That’s not a myth. Because sì sounds almost exactly like the word for "death" (sǐ), it’s considered incredibly unlucky. You’ll see buildings missing a fourth floor or phone numbers without a four. It’s a real thing that impacts real estate prices and hospital room numbering.
Five is 五 (wǔ), six is 六 (liù), seven is 七 (qī), eight is 八 (bā), nine is 九 (jiǔ), and ten is 十 (shí).
Eight is the superstar here. If four is the villain, eight is the hero. It sounds like fā, which means to get rich or prosper. People pay thousands of dollars for license plates with eights. The 2008 Beijing Olympics started on August 8th (8/8/08) at 8:08 PM. That wasn't a coincidence. It was a massive national "good luck" charm.
Cracking the Code from 11 to 20
Here is where the magic happens. In English, we have "eleven." Where did that word even come from? It’s derived from Old English words meaning "one left over" (after ten). It's clunky.
In Chinese, eleven is literally "ten one." 十一 (shí yī).
Twelve is "ten two." 十二 (shí èr).
Thirteen is "ten three." 十三 (shí sān).
This pattern continues all the way to nineteen (shí jiǔ). It is purely additive. You are just stacking the bricks you already have. Honestly, it’s a relief for anyone who struggled with rote memorization in school.
When you hit twenty, the logic shifts slightly but stays just as intuitive. Instead of a new word like "twenty," you say "two ten." 二十 (èr shí). It’s like saying you have two stacks of ten. If you wanted to say twenty-one, it would be 二十一 (èr shí yī)—"two ten one."
The Hand Signal Shortcut
If you’re in a loud bar or a busy street market, you don't even need to speak. Chinese culture has a unique system of one-handed signals for numbers 1 to 10. This is huge. In most Western cultures, we need two hands to get past five.
One through five are standard. But six is a "shaka" sign (thumb and pinky out). Seven involves pinching your thumb and first two fingers together. Eight is a "pistol" shape with the thumb and index finger. Nine is a hooked index finger. Ten is either a cross made with two index fingers or a closed fist.
Knowing these can literally save you from being overcharged. It shows you aren't just a tourist; you've actually done your homework.
Why This Logic Changes How You Think
Linguists like Malcolm Gladwell have famously discussed how the brevity of Chinese number words might actually contribute to better math skills in children. It takes less "brain space" to remember a string of numbers in Chinese than in English.
Think about it. In English, "seven" is two syllables. "Seventeen" is three. In Chinese, every number from 1 to 10 is a single, sharp syllable. This isn't just a fun fact; it’s a cognitive advantage. When your mental "loop" for holding numbers is shorter, you can process calculations faster.
Common Pitfalls for English Speakers
The biggest mistake? Mixing up 二 (èr) and 两 (liǎng).
Both mean two. But they aren't interchangeable. Use èr for counting or reading a phone number. Use liǎng when you’re talking about "two of something," like two cups of tea or two people. If you say "èr person," it sounds "off" to a native speaker. It’s like saying "I have two of shoe." You’ll be understood, but you’ll sound like a total novice.
Also, watch your tones. Since Chinese is tonal, saying shí (ten) with the wrong rising tone can occasionally lead to confusion, though in the context of counting, people usually catch your drift.

Moving Forward with Your Skills
Learning the Chinese numerals 1 to 20 is the ultimate "low effort, high reward" task in language learning. You gain immediate access to prices, dates, and times.
Next time you see a Chinese character, don't look at it as a drawing. Look at it as a piece of a logical puzzle.
- Practice the hand signals while you're walking or sitting at your desk. It builds muscle memory.
- Label things in your house using the characters. Stick a "三" on a stack of three books.
- Listen for the numbers in Chinese movies or songs. Once you recognize "shí," you'll start hearing it everywhere.
The beauty of this system is that once you've hit 20, you've already learned how to count to 99. There are no more surprises. You've broken the back of the numbering system in a single afternoon. If you want to dive deeper, start looking into "measure words" like gè (个), which are the little words you need to put between a number and a noun. That’s the next logical step in your journey to fluency.
