毛 (Máo) in Chinese Money: 三十一块二 Is ¥31.20, Not ¥31.02

The whole-yuan part of a Chinese price is the easy part. The digits after it are where money listening is won or lost, because one small syllable decides whether the amount is two 毛 or two 分, and those are ten times apart.

This guide covers the small end: what 毛 (máo) and 分 (fēn) are worth, when the unit word is dropped and when it is kept, the 零 that separates ¥31.20 from ¥31.02, and where the formal 元 / 角 / 分 ladder still turns up. Every example plays real Mandarin audio, the exact clips the countfu app uses.

Countfu is Chinese numbers listening practice: hear a price in Mandarin, type the digits. Take the free listening test.

毛 (máo) in Chinese money is a tenth of a yuan, and it usually goes unsaid

The ladder is decimal and has three rungs: 1 块 (kuài) = 10 毛 = 100 分. So 毛 is the tenths column and 分 is the hundredths column, exactly where you would put them if you were writing the price out.

In speech the last unit word gets dropped, because only one unit can follow 块 and everyone knows which one:

That bare 二 is the most useful thing on this page. A digit sitting on its own after 块 is always 毛, one step down the ladder, never 分. Learners hear 三十一块二 and write 31.02, reading the loose digit as the smallest unit. It never is. This is the same habit that turns 三百五 into 350 rather than 305, applied to money.

三十一块零二分 is ¥31.02, and the 零 is the whole difference

To actually say two 分, a speaker has to do two things: mark the empty 毛 slot with 零 (líng, zero), and then name the unit in full. Here is the same 31 yuan, read by the same voice:

Play the two clips back to back. Same speaker, same 31, and the only difference is 零 plus the word 分. That is what your ear has to catch in the second or so a price takes to go past.

The 零 is doing its ordinary job here. In any Chinese number it marks a column that has been skipped, which is why 三百零五 is 305 rather than 350. Money is the same system, and the 零 rule in full is worth reading once, because it explains the shape rather than asking you to remember it.

When the 毛 is kept: yuan amounts that end in a zero

The dropped unit has one exception, and it is not a quirk. It is there to stop a real collision.

Chinese elides plain numbers the same way: 三百五 is 350 and 一百二 is 120, with the trailing digit standing for the next unit down. So if the yuan amount already ends in a zero, a trailing money digit lands in exactly the spot big-number eliding uses. 三十块一 sits far too close to 三十一, and ¥31 is an ordinary price. Speakers close the gap by keeping the unit:

The working rule for a listener is short: if the yuan figure ends in a zero, expect to hear 毛; if it does not, expect a bare digit. Countfu's price audio is built on exactly this split, so both shapes come up constantly rather than one of them being a curiosity.

Two different 一 in two clips. ¥31.20 opens sān shí yí kuài and ¥30.10 ends yì máo. Same character, different tone, because 一 shifts according to what follows it: second tone before the fourth-tone 块, fourth tone before the second-tone 毛. The 一 tone change guide has the pattern; money is where you meet it most often.

元, 角 and 分: the register on the receipt

Everything above is how people speak. What gets written, printed and read out formally uses a parallel set of words: 元 (yuán) for 块, 角 (jiǎo) for 毛, and 分 for 分. The values are identical. 五毛 and 五角 are both ¥0.50.

The useful difference for a listener is that this register drops nothing. Every unit is named, so the amount arrives longer and more explicit:

• It is 两角, not 二角. A 2 counting something before a spoken unit takes 两 (liǎng), which is why you also get 两块 and 两毛. A 2 left bare with its unit dropped takes 二, and so does a 2 read straight after 零. The full split between 两 and 二 covers the rest.
• The pinyin says liáng jiáo wǔ, not liǎng jiǎo wǔ. Three third tones in a row cannot all stay third, so the first two rise. The word is still 两角, and if you are listening for the textbook tones you will not find them.

You meet this register on receipts, bank statements, price displays, formal announcements and most textbook audio. You meet 块 and 毛 everywhere else. Both have to map to the same digits.

分 has nearly left cash, and none of your listening

Nobody quotes a shop price to the 分 any more, and the coins are effectively out of circulation. That makes it tempting to skip the unit, which is the wrong call, because 分 did not leave the places where numbers are read out carefully:

Bank balances, interest, refunds, utility bills, app payment totals and every listening exam ever written run to two decimal places, and the 零 shape that carries them is the one learners misread. The unit that has almost left your wallet still sits in the middle of the hardest amounts to catch.

How to train it

The vocabulary here is five words, so nobody fails at this for not knowing what 毛 means. They fail because a price is over in about a second, and in that second the ear has to decide whether the last digit had a unit attached to it, which is the part a speaker gives least emphasis to. What fixes it is hearing amounts cold and finding out at once whether you wrote 31.20 or 31.02. Try these:

• 八块五 (bā kuài wǔ) = ¥8.50
• 八块零五分 (bā kuài líng wǔ fēn) = ¥8.05
• 四十块三毛 (sì shí kuài sān máo) = ¥40.30
• 两块二 (liǎng kuài èr) = ¥2.20
• 六十七元八角四分 (liù shí qī yuán bā jiǎo sì fēn) = ¥67.84

If any of them cost you a beat, that beat is what the repetition removes. The target is for 块 to land as the decimal point and for the syllable after it to arrive already knowing which column it belongs in.
