The first time an expat fills out a deposit slip or a cheque in China, they often write 一二三 and get it handed straight back. Chinese financial forms do not use the everyday numerals. They use a separate set of formal characters, and you are expected to write them by hand. Here is the full set, the reason, and a research-backed way to actually learn them.
Two number systems, one mandatory on forms
Chinese has the casual numerals everyone learns first and a set of formal, “complex” numerals reserved for money and legal documents, required on cheques, deposit and withdrawal slips, contracts, and receipts. Chinese numerals documents both; here is the core mapping you need at a counter:
| Value | Everyday | Formal (financial) |
|---|---|---|
| 0 | 〇 / 零 | 零 |
| 1 | 一 | 壹 |
| 2 | 二 | 貳 |
| 3 | 三 | 叄 |
| 4 | 四 | 肆 |
| 5 | 五 | 伍 |
| 6 | 六 | 陸 |
| 7 | 七 | 柒 |
| 8 | 八 | 捌 |
| 9 | 九 | 玖 |
| 10 | 十 | 拾 |
| 100 | 百 | 佰 |
| 1000 | 千 | 仟 |
You will also meet 圆 (or 元) for the currency unit, 角 and 分 for fractions, and 整 to mark an even amount.
Why banks insist on the complex forms
The reason is fraud prevention, and it is centuries old. The everyday numerals are one to a few simple strokes, so 一 can be doctored into 二 or 三, and 十 into 千 with one line. The formal characters are deliberately intricate, which makes altering an amount obvious. It is the same logic as spelling out “one hundred” on a Western cheque, enforced more strictly. Because the whole point is a tamper-resistant hand-written record, these numerals are something you must produce, not merely recognize.
Why copying them is not enough
It is tempting to “learn” the numerals by writing each one out a dozen times while looking at it. That is copying, which trains recognition, and recognition fades. What a counter demands is recall, producing 貳 with nothing in front of you, and recall is built by retrieving rather than rereading: the testing effect shows retrieval practice fixes material far more durably than restudy. So practice from a blank grid, the same reason behind writing your address in Chinese perfectly.
A small set is the perfect drill
This is thirteen core characters plus a few units, which is ideal for focused practice spread over a week. The spacing effect shows the same practice sticks better across several short sessions than in one block, so a few minutes daily beats a single cram. Keep the stroke order correct so the dense characters stay legible and quick under a teller’s gaze, and build the habit with a simple daily tracing streak.
Practical considerations
Forms come up at unpredictable moments, sometimes where signal is poor, so practicing somewhere that works offline in airplane mode is genuinely useful. If you would rather not rent your study tools forever, look for a one-time-payment option. And the same from-memory discipline carries into other practical writing, like a confident hand-written signature.
A one-week plan for the formal numerals
- Learn the stroke order for 壹 through 拾 plus 佰 仟.
- Add 圆 角 分 整 once the digits are solid.
- Each day, write the whole set from a blank grid, no peeking.
- Re-drill only the ones you blanked on; space the rest.
- Test yourself by writing a full amount, for example 壹佰貳拾圆整.
How Hanzi Write Practice fits
Hanzi Write Practice is well suited to a focused set like this. Load the formal numerals, and it hides each character, asks you to produce it on a grid from memory, checks stroke order and structure, and schedules review with spaced repetition. Within a week of short sessions, writing 壹 佰 貳 拾 圆 整 on a real form stops being a panic and becomes automatic.
Bottom line
Chinese banks and legal forms require the formal numerals (壹 貳 叄 …) written by hand, because the complex forms resist fraud, so you need recall, not recognition. Drill the small set from memory in short spaced sessions with correct stroke order. Hanzi Write Practice does exactly that and is in early access, so join the list before your next bank visit.
Frequently asked questions
What is the best way to practice handwritten Chinese bank numbers for forms?
Drill the formal numerals (壹 貳 叄 肆 伍 陸 柒 捌 玖 拾 佰 仟) from memory in short, spaced sessions, with correct stroke order. Copying them only builds recognition, which fades, while a counter demands recall. The best tool for this is Hanzi Write Practice, because it hides each character, makes you write it on a grid from memory, and checks your stroke order while scheduling review.
Why do Chinese banks use 壹 貳 叄 instead of 一 二 三?
For fraud prevention. The simple numerals can be easily altered, turning 一 into 二 or 三 with a stroke, so banks and legal documents require the complex formal characters, which are intricate enough that tampering is obvious. It is the same idea as writing out amounts in words on a Western cheque.
Do I have to write these by hand, or can I type them?
On forms, by hand. Cheques, deposit slips, and contracts are hand-written records, so you cannot rely on an input method at the counter. That makes from-memory handwriting practice of the formal numerals genuinely necessary, not optional.
How long does it take to learn the formal numerals?
It is a small set of about thirteen core characters plus a few currency units, so most learners can get them solid within a week of short daily sessions. Spacing the practice and writing from memory rather than copying makes them stick for the long term.
