An English speaker opening a Chinese dictionary hits a wall immediately: there is no alphabet, so there is no single A–Z order to look things up by. This isn't a flaw — it's the direct consequence of a writing system where a character encodes a meaning and a syllable rather than a spelling. The Chinese solution is elegant: a dictionary gives you two different indexes, and you choose the one that matches what you already know. If you know how a character sounds, you look it up by pinyin. If you only know how it looks, you look it up by radical and stroke count. This page walks through both routes with worked examples.
The core idea: pick the index that matches what you know
Every serious Chinese dictionary — the pocket 《新华字典》 (Xīnhuá Zìdiǎn) that every schoolchild owns, or any bilingual app — is really several lookup tables bundled together. The two that matter are:
| You know… | Use this index | How it's ordered |
|---|---|---|
| the pronunciation | the pinyin index (音节表, yīnjié biǎo) | alphabetically by syllable, then by tone |
| only the shape | the radical index (部首检字表, bùshǒu jiǎnzì biǎo) | by radical, then by remaining stroke count |
The mental adjustment for an English speaker is real. In an English dictionary there is exactly one path in — spelling — and it works even for a word you can't pronounce. In Chinese you must choose your door based on your evidence. Heard a word but never saw it? Pinyin door. Saw a character on a sign but have no idea how it sounds? Radical door. Neither door is "the main one"; you keep both keys.
这个字我会念，用拼音查最快。
zhège zì wǒ huì niàn, yòng pīnyīn chá zuì kuài
I can pronounce this character, so looking it up by pinyin is fastest. (informal)
不会念的字，就按部首查。
bú huì niàn de zì, jiù àn bùshǒu chá
For characters you can't pronounce, look them up by radical. (neutral)
Route 1 — by pinyin (when you know the sound)
If you can say the character, this route is trivial and feels almost like English. Pinyin entries are ordered alphabetically by the romanized syllable, and within one syllable, by tone: first tone, then second, third, fourth, then the toneless neutral. Within the same syllable and tone, characters are usually sub-ordered by stroke count.
To find 好 (hǎo, "good"): go to h, find the syllable hao, then within hao find the third-tone group. There it is. To find 在 (zài): z → zai → fourth tone.
| Character | Pinyin | Look under |
|---|---|---|
| 好 | hǎo | h → hao → 3rd tone |
| 在 | zài | z → zai → 4th tone |
| 妈 | mā | m → ma → 1st tone |
好 在拼音表里排在 h 那一部分。
hǎo zài pīnyīn biǎo lǐ pái zài h nà yí bùfen
好 is filed under the 'h' section of the pinyin index. (neutral / academic)
同一个音节，先按声调排。
tóng yí ge yīnjié, xiān àn shēngdiào pái
Within the same syllable, entries are ordered by tone first. (academic)
The catch is obvious: this route only works if you already know the pronunciation. That's why, when you meet a brand-new character on a menu with no idea how to say it, you can't use pinyin — you need the shape-based route.
Route 2 — by radical + stroke (when you only know the shape)
This is the classic Chinese lookup, and it's a two-step process:
- Identify the 部首 (bùshǒu, the "radical" — the indexing component). Modern mainland dictionaries use a standardized set of about 201 radicals.
- Count the remaining strokes — the strokes left over after the radical — and find that number within the radical's section.
Work through 好 (hǎo) by shape. Its radical is 女 (nǚ, "woman"), which itself is 3 strokes. Remove the 女 and what's left is 子 (zǐ, "child"), which is 3 strokes. So: go to the 女 radical section, then to the "remaining 3 strokes" subsection, and 好 is listed there.
| Character | Radical | Strokes in radical | Remaining strokes |
|---|---|---|---|
| 好 (hǎo) | 女 (woman) | 3 | 3 (子) |
| 河 (hé) | 氵 (water) | 3 | 5 (可) |
| 请 (qǐng) | 讠 (speech) | 2 | 8 (青) |
好 的部首是 女，再数三画。
hǎo de bùshǒu shì nǚ, zài shǔ sān huà
The radical of 好 is 女; then you count three more strokes. (neutral)
先找部首，再数剩下的笔画。
xiān zhǎo bùshǒu, zài shǔ shèngxià de bǐhuà
First find the radical, then count the remaining strokes. (neutral / academic)
This route's superpower is that it needs no knowledge of the sound at all — pure shape gets you there. That's exactly why it exists: it's the door for characters you've never heard pronounced. For why these indexing components are called radicals, and how to spot them, see what radicals are.
When the radical isn't obvious: the total-stroke fallback
Here's the honest difficulty. Identifying the radical is not always easy, and beginners get stuck here and give up — which is a mistake, because every dictionary provides a backup index for exactly this problem.
Some characters have genuinely non-obvious radicals. 我 (wǒ, "I") is filed under the radical 戈 (gē, "spear") — almost nobody guesses that. 的 (de) is under 白 (bái, "white"). When you can't find the radical, don't quit: flip to the 总笔画索引 / 难检字笔画索引 (the total-stroke-count index for hard-to-index characters), count every stroke in the whole character, and look it up by that number. 我 is 7 strokes total, so you'd find it in the "7 strokes" list.
| Character | Actual radical | Why it's a trap | Total strokes (fallback) |
|---|---|---|---|
| 我 (wǒ) | 戈 (spear) | the 戈 is buried and unobvious | 7 |
| 的 (de) | 白 (white) | looks like two equal halves | 8 |
找不到部首，就按总笔画查。
zhǎo bú dào bùshǒu, jiù àn zǒng bǐhuà chá
If you can't find the radical, look it up by total stroke count. (neutral)
我 这个字的部首是 戈，很多人猜不到。
wǒ zhège zì de bùshǒu shì gē, hěn duō rén cāi bú dào
The radical of 我 is 戈 (spear) — a lot of people can't guess it. (informal / academic)
A third door you'll occasionally meet: four-corner and digital lookup
Two more systems are worth recognizing, even if you rarely use them by hand:
- The 四角号码 (sìjiǎo hàomǎ, "four-corner method") assigns each character a number based on the shape of its four corners — fast for experts, cryptic for beginners. You'll see it referenced in older or scholarly dictionaries.
- Digital lookup has quietly become most learners' default: type the pronunciation into a pinyin IME or handwrite the character with your finger/mouse and the app finds it. Handwriting-input lookup is the modern answer to "I don't know the sound or the radical" — you just draw it.
现在很多人用手机手写查生字。
xiànzài hěn duō rén yòng shǒujī shǒuxiě chá shēngzì
These days a lot of people look up unfamiliar characters by handwriting them on their phone. (neutral)
会念就打拼音，不会念就手写。
huì niàn jiù dǎ pīnyīn, bú huì niàn jiù shǒuxiě
If you can pronounce it, type pinyin; if you can't, handwrite it. (informal)
Common Mistakes
1. Expecting one A–Z order like an English dictionary. There isn't one. You choose an index — pinyin or radical-plus-stroke — based on whether you know the sound or only the shape.
❌ 我想按一个字母顺序查所有汉字。
wǒ xiǎng àn yí ge zìmǔ shùnxù chá suǒyǒu hànzì
Incorrect expectation — 'I want to look up every character by one alphabetical order.' No such single order exists.
✅ 会念用拼音，看形用部首。
huì niàn yòng pīnyīn, kàn xíng yòng bùshǒu
Right approach — know the sound → pinyin; only the shape → radical.
2. Giving up when you can't identify the radical. The radical of 我 (戈) and 的 (白) fool almost everyone. Don't quit — switch to the total-stroke index, which needs no radical at all.
3. Miscounting the remaining strokes vs. the total strokes. The radical index wants the strokes left after removing the radical; the fallback index wants all strokes. Mixing them up sends you to the wrong subsection.
❌ 在部首表里数了全部笔画。
zài bùshǒu biǎo lǐ shǔ le quánbù bǐhuà
Incorrect — counting all the strokes while in the radical index (it wants only the remaining strokes).
✅ 部首表数剩下的，总画表数全部的。
bùshǒu biǎo shǔ shèngxià de, zǒng huà biǎo shǔ quánbù de
Right — remaining strokes for the radical index, all strokes for the total-stroke index.
4. Forgetting the tone order within a pinyin section. Under the same syllable, entries run 1st → 2nd → 3rd → 4th → neutral. Looking for a fourth-tone character at the top of the ma section wastes time.
5. Assuming you must do it by hand. For most learners, handwriting-input or pinyin lookup on a phone is faster and needs no radical hunting. Learn the radical method to understand the system, but use the tool that's quickest for the character in front of you.
Key Takeaways
- Hanzi have no alphabet, so a dictionary gives two indexes, and you pick the one matching what you know.
- Pinyin index (when you know the sound): alphabetical by syllable, then by tone (1→2→3→4→neutral).
- Radical-plus-stroke index (when you only know the shape): find the 部首 radical, then count the remaining strokes — e.g. 好 = 女 radical + 3 remaining.
- When the radical isn't obvious (我 → 戈, 的 → 白), fall back to the total-stroke-count index — count every stroke; it always works.
- Digital lookup — typing pinyin or handwriting the character — is the modern default and solves the "know neither sound nor radical" case.

- What Radicals (部首) AreHSK 1 — A radical (部首) is the classifying component a character is filed under in the dictionary, and it usually points at a meaning domain — so once you can spot the water radical or the tree radical, a wall of opaque characters turns into half-guessable ones.
- What a Stroke (笔画) IsHSK 1 — A stroke is a single continuous line written without lifting the pen — the atomic unit every Chinese character is built from, the way letters build English words.
- Typing Chinese (the Pinyin IME)HSK 2 — Almost everyone types Chinese with a pinyin IME (input method editor): you type the romanized sound — nihao, zhongguo — and the software offers a candidate list of characters, using context and frequency to guess whole words and phrases so you type several syllables and press space; the catch is that you must know a character's pronunciation to type it, and homophones (shì → 是/事/市/试) force you to pick the right candidate.
- Pinyin Is Spelling, Not a ScriptHSK 1 — 汉语拼音 (Hànyǔ Pīnyīn) is a Roman-alphabet system for transcribing Mandarin pronunciation — a pronunciation aid, teaching tool, and typing input, not the language's real writing system, which is hanzi; and its letters carry Mandarin values, not English ones (c = 'ts', q ≈ a forward 'ch', x = a hissy 'sh', zh/ch/sh are retroflex), so pinyin is a code you must relearn rather than read with English phonics.
