Chinese Name Romanizer (Passport Pinyin)
How to use
Enter the Chinese name
Type the full Chinese name, e.g. 李明 or 歐陽娜娜. The tool reads only Han characters; spaces and punctuation are ignored.
Mark the surname length
By default the first character is the surname. For compound surnames (歐陽, 司馬, 諸葛…) choose "Compound (2 chars)" so the tool splits surname from given name correctly.
Click "Romanize name"
You get four systems at once — Hanyu Pinyin, Wade–Giles, Tongyong Pinyin, and Cantonese/Hong Kong spelling — each shown in surname-first passport order and Western (given-first) order.
Pick the system that applies
PRC passports use Hanyu Pinyin; older Taiwan documents often use Wade–Giles (張 → Chang); Hong Kong IDs use Cantonese spelling. Always defer to your issuing authority and any existing document spelling.
Romanizing a Chinese Name: The Four Systems Behind "Passport Pinyin"
When a Chinese name has to be written into a passport, an airline ticket, a diploma, or a bank account, it must be romanized — transliterated into the Latin alphabet. The catch is that the Chinese-speaking world never settled on a single romanization standard. The same character 張 appears as Zhang on a mainland-China passport, possibly Chang on an older Taiwan document, and Cheung on a Hong Kong ID where it is spelled by Cantonese sound. These are not mistakes — they are parallel systems shaped by history and geography. This tool romanizes one Chinese name into all four mainstream systems at once and lays them out in both surname-first passport order and Western given-first order, so you can see exactly why documents disagree.
Where the four systems come from
Hanyu Pinyin was promulgated in mainland China in 1958 and later adopted as ISO 7098; it is used on PRC passports, in Singapore, and in most official contexts today, with the surname first and the given name joined (李明 → LI Ming). Wade–Giles is the older system devised by 19th-century British diplomats; it remained standard in Taiwan until the 2009 switch to Hanyu Pinyin and still appears on countless overseas-Chinese passports and academic by-lines, recognisable by spellings like 張→Chang, 徐→Hsu, 蔡→Tsai. Tongyong Pinyin was Taiwan's official system from 2002 to 2008, differing from Hanyu in a bounded set (zh→jh, q→c, x→s, and so on) and still surviving on a minority of documents. Cantonese / Hong Kong spelling follows Cantonese pronunciation entirely; this tool approximates it with tone-stripped Jyutping, but the actual spelling on a Hong Kong ID is frequently an even older anglicised convention that does not match Jyutping exactly.
"Different spellings of one name aren't errors — they're parallel systems left behind by history and geography."
Why this matters especially for ASEAN Chinese
In Singapore, Malaysia, Indonesia, and Hong Kong, members of the same family can carry completely different surname spellings on their passports depending on when and where each document was issued — a father spelled Tan while his children are registered as Chen is not unusual. Names on airline bookings must match the passport letter-for-letter, and school enrolment, visa applications, and inheritance claims routinely require extra proof when spellings diverge. The value of this tool is that it shows, at a glance, what "the same Chinese name" should look like across each system, so you can cross-check before filling a form and make an informed choice when changing a name or naming a child. All computation runs locally in your browser; the name is never uploaded or stored, in line with the RECATOOLS zero-tracking principle. Remember the golden rule: the final spelling on any official document is governed by the issuing authority's rules and your existing paperwork — this tool is a spelling reference and cross-check only.
10 Facts about Romanizing Chinese Names
Mainland-China passports use Hanyu Pinyin uniformly — surname first, given name joined, with the surname (or the whole name) capitalised. 李明 becomes LI Ming or LI MING.
In Wade–Giles, 張 is Chang, 徐 is Hsu, and 周 is Chou. These "wrong-looking" spellings were in fact the standard in pre-2009 Taiwan and for many overseas Chinese.
Hong Kong ID names are spelled by Cantonese sound and often keep an older anglicised convention: 陳 → Chan, 黃 → Wong, 李 → Lee — not necessarily identical to standard Jyutping.
Within one family, parents and children can carry different surname spellings (e.g. Tan vs Chen) purely because documents were issued in different eras or places — very common among Singapore/Malaysia/Indonesia Chinese.
On flight bookings, the romanized name must match the passport letter-for-letter — including spaces and hyphens — or boarding can be refused. Checking the spelling first avoids trouble.
Hanyu Pinyin was adopted by ISO as ISO 7098 in 1982, the only international standard for Chinese romanization — but it governs spelling only, not name capitalisation or ordering.
Tongyong differs from Hanyu in a bounded, rule-based set: zh→jh, q→c, x→s, ong/iong handling, etc. Most syllables are actually spelled the same — 明 is Ming in both.
Compound surnames (歐陽, 司馬, 諸葛, 上官…) are two characters and should be romanized as a single surname unit — 歐陽 → Ouyang, not Ou Yang.
Wade–Giles originally used aspiration apostrophes (p', t', ch'), but real documents almost always drop them — so 張 and 章 both end up as Chang, a known limitation of the system.
This tool only transliterates spelling — no server calls, no name stored. It shows the "standard expected spelling," but the final spelling on an official document is always governed by the issuing authority and your existing paperwork.
Frequently Asked Questions
-
It depends on the issuing authority. Mainland-China passports use Hanyu Pinyin; current Taiwan passports also use Hanyu Pinyin but older documents may be Wade–Giles or Tongyong; Hong Kong passports use Cantonese spelling. The key rule is consistency with your existing documents. This tool shows what each system would produce, but the issuing authority governs.
-
Because that is Wade–Giles, an older system predating Hanyu Pinyin. In Wade–Giles, Hanyu's zh maps to ch, so 張 is Chang. Pre-2009 Taiwan and many overseas-Chinese documents use Wade–Giles, which is why spellings like Chang, Hsu, and Tsai are so common — they are not errors, just a different standard.
-
Select "Compound (2 chars)" in the tool. It then romanizes the first two characters as a single surname unit — 歐陽 → Ouyang, not Ou Yang. Common compound surnames include 歐陽, 司馬, 諸葛, 上官, 東方, and 夏侯.
-
Passports and most official forms use surname-first (e.g. LI, Ming), matching Chinese convention; everyday Western writing often puts the given name first (Ming Li). The tool shows both orders so you can match the form. For flights, fill the "surname" and "given name" fields exactly as on your passport.
-
No. All transliteration runs locally in your browser with no server calls — the name is neither uploaded nor stored. RECATOOLS enforces zero-tracking + zero-storage across all tools.
-
The differences are limited and rule-based. The main ones are zh→jh, q→c, x→s, and a few finals (-iong, -ui, -iu). Most syllables are identical across both — 明 is Ming, 華 is Hua in either. Tongyong was Taiwan's official system 2002–2008 and still survives on some documents.
-
Hong Kong name spellings mostly come from colonial-era anglicised conventions that predate standard Jyutping and carry no tone marks — 李 is often Lee rather than Lei, 張 is Cheung. The tool approximates with tone-stripped Jyutping, but the actual spelling on your ID governs.
-
When applying for a first document with no existing spelling, you can usually choose within what the issuing authority allows. Many families keep a child's surname spelling consistent with the parents' to ease future visas, inheritance, and kinship proof. The tool lets you preview each system as informed reference, but check the specific rules with your local authority.
-
Yes. A few characters have multiple readings (單 can be Shan or Dan, 區 can be Ou or Qu), and the surname reading can differ from the common one. The tool transliterates by the most common reading; if your surname has a special reading, defer to your document or family convention and verify it yourself.
-
No. The tool is for spelling reference and cross-system comparison, using standard romanization tables — but name spelling on official documents must follow the issuing authority (passport office, immigration, etc.) and your existing paperwork. Hong Kong and Macau IDs often carry legacy spellings that this tool's output should not override. Verify important documents with the relevant authority.
