Pinyin vs Wade-Giles vs Zhuyin: Which to Learn?
Why Peking became Beijing, what the apostrophes in Wade-Giles mean, and why Taiwan teaches a system that uses no Latin letters at all.
Published
If you have read anything about China written before about 1980, you have met Wade-Giles: Mao Tse-tung, Peking, Taoism, Kung-fu. If you have studied Chinese in Taiwan, you have met Zhuyin, which uses symbols rather than Latin letters. And if you have looked at a Taiwanese street sign, you may have met two or three systems on the same road.
You only need to learn one system actively. But knowing how the others map onto it saves you from a specific and common confusion: thinking Tsingtao and Qingdao are different places.
The systems you will actually encounter
Dozens of romanisations have been proposed since the seventeenth century. Four matter in practice.
- Hanyu Pinyin — the PRC standard since 1958, ISO standard since 1982, and the international default. This is what you should learn.
- Wade-Giles — developed by Thomas Wade and refined by Herbert Giles in the nineteenth century. Dominant in English-language scholarship until the 1980s and still embedded in historical writing, older library catalogues and a handful of fossilised brand names.
- Zhuyin Fuhao (Bopomofo) — not a romanisation at all. Thirty-seven phonetic symbols derived from character components, developed in 1913 and still the standard for teaching and typing in Taiwan.
- Tongyong Pinyin — Taiwan's official system from 2002 to 2008, now superseded by Hanyu Pinyin but still visible on signage installed during that window.
Why Peking became Beijing
The shift in English-language media happened between roughly 1979 and 1986, as news agencies adopted pinyin following the PRC's formal request that it be used internationally. Peking became Beijing, Canton became Guangzhou, Mao Tse-tung became Mao Zedong.
Peking is not, strictly, Wade-Giles — it comes from an older postal romanisation based partly on southern pronunciations and partly on early Jesuit transcriptions. Wade-Giles would give Pei-ching. But the general point holds: the older forms encode either archaic pronunciations or a different mapping of sounds to letters.
A residue of older spellings survives where a name became a brand or an institution. Tsingtao beer is Qingdao. Peking University still calls itself that in English. Tsinghua University is Qinghua. Kung fu is gōngfu. These are not errors; they are trademarks and institutional names that predate the switch.
Reading Wade-Giles if you meet it
The defining feature of Wade-Giles is the apostrophe, which marks aspiration. In Wade-Giles, t is an unaspirated sound and t' is the aspirated one; pinyin writes these as d and t. The apostrophes were frequently dropped in casual usage, which destroyed the distinction entirely — this is the main reason Wade-Giles acquired a reputation for being confusing, and a large part of why Taoism and Daoism are the same word.
| Wade-Giles | Pinyin | Example (W-G → Pinyin) |
|---|---|---|
| p / p' | b / p | Pei-ching → Beijing |
| t / t' | d / t | Tao → Dao |
| k / k' | g / k | Kung → Gong |
| ch / ch' | j, zh / q, ch | Chou → Zhou |
| hs | x | Hsi-an → Xi'an |
| j | r | jen → ren |
| ts / ts' | z / c | tsai → zai |
| -ung | -ong | Kung-fu → gōngfu |
Zhuyin: the system that is not a romanisation
Zhuyin Fuhao, universally called Bopomofo after its first four symbols ㄅㄆㄇㄈ, uses 37 purpose-built symbols derived from simplified character forms. ㄅ is b, ㄆ is p, ㄇ is m, ㄈ is f.
Its pedagogical advantage is real: because the symbols exist only for this purpose, a learner has no prior associations to unlearn. A child learning ㄑ has no idea what a q normally sounds like, so there is nothing to interfere. Pinyin's q, x and c cause persistent trouble for exactly the opposite reason.
Its disadvantage is equally real: the symbols exist only in Chinese contexts, are not on any standard keyboard outside Taiwan, and cannot be used to write Chinese names in a Latin-script document. For a foreign learner the network effects overwhelmingly favour pinyin.
If you are studying in Taiwan, learn Zhuyin — your classmates, teachers and dictionaries use it, and typing without it is awkward. Otherwise, learn pinyin.
What to actually do
Learn Hanyu Pinyin actively. It is the ISO standard, the input method that ships everywhere, the system every modern textbook and dictionary uses, and the one that lets you type Chinese on any device you will ever own.
Learn to recognise Wade-Giles passively — enough to guess that Ch'ing is Qing and Szechuan is Sichuan. This takes an afternoon with the mapping table and saves you from confusion whenever you read older scholarship or a restaurant menu.
Ignore Tongyong Pinyin unless you are navigating Taiwanese signage from the 2000s, in which case just note that it is close enough to Hanyu Pinyin to be readable: jh for zh, si for xi, ci for qi.
And be aware that Taiwanese street signs are genuinely inconsistent. The same road can appear in Hanyu Pinyin, Tongyong Pinyin and a pre-existing ad hoc spelling within a few blocks, because signage was replaced piecemeal across several policy changes.
Key takeaways
- Hanyu Pinyin is the ISO standard and the only system worth learning actively.
- Wade-Giles apostrophes mark aspiration: t' is pinyin t, plain t is pinyin d.
- Peking, Tsingtao and Kung fu are fossilised older spellings, not alternative places.
- Zhuyin uses 37 purpose-built symbols and is standard in Taiwan.
- Learn to read Wade-Giles passively; it takes an afternoon and unlocks older scholarship.
Frequently asked questions
Is Taoism or Daoism correct?
Both refer to the same thing. Tao is Wade-Giles, Dao is pinyin, and the pronunciation is the same in each — the initial is an unaspirated d sound. Daoism is the modern convention; Taoism persists in established titles.
Why do Chinese passports use pinyin without tone marks?
Machine-readable travel documents are restricted to basic Latin characters. Tone marks are dropped, and syllables in a given name are usually run together: 王小明 becomes WANG XIAOMING.
Does Taiwan use pinyin now?
Hanyu Pinyin has been the official romanisation for international use and place names since 2009, but Zhuyin remains the system taught in schools and used for typing. Both coexist.
