A native speaker just said this. What number is it?

The app trains this with real Mandarin audio. Coming soon.

What you'll practice

Six listening test types aimed at the moments that actually trip learners up: a taxi fare, a phone number at speed, a discount at the till.

Numbers 数字

From 零 to 亿. The ten-thousand regrouping that never automatizes on its own: 三十五万 is 350,000 and 两千三百万 is 23,000,000. Train it until it is reflex.

Prices 价格

Colloquial and , the way shops and taxis actually say it. 三块五 is ¥3.50, and the trailing unit disappears exactly when you need it.

Dates & Years 日期

Years read digit by digit: 二零二六年 is 2026. Months with , days with , and the year-month-day order that trips US-trained ears.

Times 时间

两点 is 2:00 and never 二点. Halves with , quarters with , and 差五分 patterns at conversation speed.

Phone Numbers 电话号码

11-digit mobile numbers in the real 3-4-4 rhythm, with instead of : the digit speakers swap in so 1 never sounds like 7.

Percent & Discounts 打折

百分之三十 puts the 30 last in 30%. 打八折 means 20% off, not 80%. The shopping math no app trains.

Frequently Asked Questions

What is Countfu?

Countfu is a focused listening-practice tool for Chinese numbers. It plays a number in Standard Mandarin, you type the digits you hear, and you get an instant score. It is built for Mandarin learners who know the number words on paper but cannot catch them at native speed.

Why are Chinese numbers so hard to understand by ear?

Three problems stack up. Chinese groups large numbers by ten-thousand, so 三十五万 is 35 x 10,000 = 350,000 and you must regroup in your head while listening. Colloquial speech drops trailing units, so 三百五 means 350, not 305. And (sì, 4) versus (shí, 10) is a genuine minimal pair at speed. Focused listening practice is the only reliable fix.

What will I be able to practice?

Cardinal numbers from up to 亿-scale, prices in colloquial and , dates and digit-by-digit years, times, 11-digit phone numbers with for 1, and percentages and discounts like 打八折 (20% off).

Do I need to type Chinese characters?

No. You always answer in digits: hear 三百五, type 350. No character input, no IME, no pinyin typing.

Is the audio Mandarin or Cantonese?

Standard Mandarin (Putonghua), with native-speaker quality control on every audio file. Cantonese numbers sound completely different and are not covered.
