Learn Chinese Vocabulary: The 400 Words That Unlock A1

July 21, 2026 · 7 min read

There is a shortcut to learning Chinese vocabulary, and it is not a memory trick. It is an ordering trick: study words in the order the language actually uses them, not in the order a textbook happens to introduce them. The numbers are stark. The 400 highest-value words cover 92% of the running words in A1-level Chinese text. Learn those 400 first and roughly nine out of ten words on any beginner page are already yours; most of the rest you can guess from context.

That is the entire pitch behind our A1 Core course: exactly those 400 words, taught with a Leitner spaced-repetition drill whose intervals run from 6 hours to 30 days, free forever — no trial period, no card on file. This post lays out the evidence: why a Chinese frequency list beats chapter order, what 92% coverage actually feels like when you read, how the drill schedule works, and why we do not charge for any of it.

Why frequency order is the fastest way to learn Chinese vocabulary

Open a typical beginner textbook and look at the chapter titles: family members, colors, the classroom, days of the week. Thematic ordering is convenient for a teacher planning a Tuesday lesson. For a learner trying to read, it is close to random. A themed chapter mixes a few genuinely common words with a pile of vocabulary you might not meet again for months, and it delays the small, unglamorous words that appear in nearly every sentence.

Word frequency in every language follows a brutally steep curve. A handful of words — 的, 是, 我, 你, 了 — do an enormous share of the work, and each step down the list adds less and less coverage. When you learn Chinese vocabulary in frequency order, every new word buys you the largest possible amount of real text. When you learn it in chapter order, some words pay off immediately and others sit unused in your memory until they quietly fall out of it.

Textbook chapter orderFrequency order
First weeks spent onThemed sets — colors, classroom objects, kinship terms — common or notThe words that appear in almost every sentence
Reading real textDelayed; coverage grows slowly and unevenlyFast; each word raises coverage by the maximum amount
Review burdenRarely-seen words decay and need constant re-learningFrequent words get free reinforcement every time you read
Motivation"When will I ever use this?"Visible progress in real sentences within days

None of this means themed vocabulary is useless — you will eventually want the word for eraser. It means themes are a terrible sequence. Frequency first, themes later, is the order that gets you reading.

What "400 words cover 92% of A1 text" actually means

Coverage is a precise, slightly unintuitive idea, so let us be honest about it. 92% coverage means that out of every 100 running words in an A1-level text, about 92 are words from the core 400. It does not mean you understand 92% of the meaning — a single unknown word can hide the point of a sentence. What it does mean is that unknown words become occasional rather than constant: roughly one word in twelve instead of a wall of mystery characters.

That density changes what reading is. Below it, "reading" collapses into dictionary work — decode a word, forget the sentence, start over. At 92%, a graded text becomes a puzzle you can actually solve: the sentence frame is familiar, context does real work, and each unknown word sits inside meaning instead of noise. In our reader you tap the word, see pinyin and English, and keep going; the tap-and-continue loop only works when taps are rare, and 400 words is what makes them rare.

One more honest caveat: 92% holds for A1-level text — text controlled to that band, like the A1 tier of our graded books and stories. Four hundred words will not give you 92% of a newspaper. That is not a flaw; it is the argument for graded material. You climb to native text through levels, not around them.

Where HSK 1 vocabulary fits

If you are heading for the exam: HSK 1 vocabulary overlaps heavily with the top of any Chinese frequency list, because the exam designers draw on the same usage data. The classic HSK 1 list has 150 words; the newer HSK 3.0 standard raises band one to about 500. The difference is intent. HSK lists are a testing syllabus, usually presented alphabetically or by theme in prep books. The A1 Core is sequenced by value — the words that unlock the most text come first — so studying it does not conflict with HSK prep; it front-loads the part of the exam list you will meet most often in the wild.

How the Leitner drill works: 6 hours to 30 days

Knowing which 400 words to learn is half the problem. The other half is not forgetting them, and for that the A1 Core uses a Leitner system — spaced-repetition boxes with intervals from 6 hours to 30 days.

  1. Every word lives in a box. New words start at the bottom.
  2. Answer correctly and the word moves up a box, and waits longer before it returns.
  3. Miss it and it drops back down, returning to short intervals until it sticks.

The endpoints matter. The first interval is 6 hours because the steepest forgetting happens on day one — a same-day second exposure is cheap insurance on every new word. The top interval is 30 days because a word you can still recall after a month is functionally yours; capping the ladder there keeps mature words from cluttering your queue while still catching the occasional leech before it fully escapes.

The same drill system runs inside our interactive book courses, where all 33 classics exist at six CEFR levels so you can reread the same story as you level up — which means the habits you build in the A1 Core transfer directly to everything that comes after it.

Why the A1 Core is free forever

Not free-trial free. Not free-until-we-raise-a-round free. Free forever, because it is the honest front door to everything else we sell. Our books are one-time purchases, and our 1,051 graded stories and 1,099 dialogs will run on a Pro subscription (coming soon). Both are dramatically better products for someone who already owns the core 400 words — you arrive at your first book able to actually read it. Giving the foundation away costs us little and makes every paid thing we offer work better. That is the entire business logic; there is no catch to disclose.

For comparison: DuChinese charges $14.99 a month for graded stories with a rotating free set. The stories are fine — but there are no companion book courses and no word-drill system, so the vocabulary you meet has nowhere to be systematically kept. We think the drill is the part you should never have to pay for.

Start with the free things

You do not need to take our word for any of this — the evidence is testable in an afternoon.

  • The A1 Core — all 400 words with the full 6-hour-to-30-day drill, free forever with a free account.
  • The free level test — if you are past zero, find your level first so you drill the right material.
  • Free sample stories — a sample set opens with no account at all, and the Daily Life topic is free with a free account, so you can feel what 92% coverage reads like before you commit to anything.

Learn Chinese vocabulary in the order Chinese actually uses it, keep it with a schedule built on how forgetting actually works, and read from week one. That is the whole method — and the first 400 words are on us.
