HSK 0 is not an official exam level. It is the name GraphChinese gives the foundations every HSK level silently assumes: the four tones, the pinyin system, stroke order, and the most common radicals. Skipping these is the most common reason self-study stalls, so GraphChinese teaches them as explicit topics with the same mastery gating as everything else.

Which HSK level do I need for a Chinese university?

Requirements vary by university and program, but degree programs taught in Chinese commonly ask for HSK 4 (often for science and engineering) or HSK 5 (often for humanities and business). Always check the specific program's published requirement.

Do the HSK levels build on each other?

Yes — each level's vocabulary and grammar assume full command of everything below it. That is why gaps compound: shaky HSK 2 grammar makes HSK 4 sentences unreadable. GraphChinese makes the dependency explicit with a knowledge graph and does not unlock a topic until its prerequisites are proven mastered.

The HSK levels, explained

Q: Is HSK 6 the same as fluency?

HSK 6 certifies that you can comfortably read long texts, follow lectures and media, and express yourself fluently in writing and speech — roughly 5,000 words of active vocabulary. It is the top of the six-level exam ladder and a genuine mastery milestone, but like any exam it measures what it tests: educated native speakers know several times more words, and real-world fluency also depends on listening speed and conversational practice.

The HSK (汉语水平考试, Hànyǔ Shuǐpíng Kǎoshì) is the standard proficiency exam for Mandarin Chinese, administered worldwide through Chinese Testing International. Six levels ladder from first words to comfortable fluency, and because Chinese is built on dependencies, each level assumes full command of everything below it. Here is what each level actually asks of you, what you can do when you get there, and the part the exam never mentions: the ladder really starts before HSK 1.

The six levels at a glance

Word counts below are the cumulative vocabulary of the six-level standard the exams are built on. The last column is GraphChinese's own map of the same ground — how many distinct topics (vocabulary clusters, grammar points, and skills) the level breaks into when you chart every dependency.

Level	Vocabulary	What you can do	Topics in GraphChinese
HSK 0 (unofficial)	—	Hear and produce the four tones, read pinyin, write characters in correct stroke order, recognize common radicals.	19
HSK 1	150 words	Understand and use very simple phrases: introduce yourself, count, tell time, ask basic questions.	54
HSK 2	300 words	Handle simple everyday exchanges — shopping, directions, daily routines — in short, direct sentences.	64
HSK 3	600 words	Manage most daily situations: travel, work small-talk, opinions in simple terms. The level where conversations become sustainable.	65
HSK 4	1,200 words	Discuss a wide range of topics with native speakers, read short articles, follow the gist of TV. The common bar for university study in Chinese.	128
HSK 5	2,500 words	Read newspapers and magazines, follow films, give structured presentations. Comfortable in professional settings.	197
HSK 6	5,000+ words	Comfortably comprehend long texts and lectures; express yourself fluently in speech and writing.	216

Notice the shape: the top three levels contain most of the material. HSK 1–3 together cover 600 words; HSK 4 alone doubles that, and HSK 5–6 together nearly quadruple it again. In GraphChinese's graph the same funnel shows up in topic counts — 183 topics carry you through HSK 3, and 541 more take you to HSK 6. Plans that treat all six levels as equal-sized steps are why so many learners stall at the HSK 4 wall.

HSK 3.0: the nine-band standard

In 2021 China published a revised proficiency standard that reorganizes the vocabulary into nine bands — roughly 500 words at band 1, rising past 11,000 words across the advanced bands 7–9. As of 2026 the exams most learners take for levels 1–6 still follow the six-level structure above, with a separate combined HSK 7–9 exam (introduced in 2022) for advanced learners headed into academia or translation. For self-study planning, the six-level ladder remains the practical map, and it is the one GraphChinese's curriculum is organized around.

The level before level one

Every HSK level silently assumes a foundation the exam never tests directly: hearing and producing the four tones, reading pinyin fluently, writing characters with correct stroke order, and recognizing the radicals that make new characters memorable instead of arbitrary. Learners who skip this layer pay for it at every level above — tones fossilize badly, characters become thousands of unrelated pictures, and listening never catches up.

In GraphChinese: these foundations are HSK 0 — 19 explicit topics at the base of the dependency graph, gated and reviewed like everything else. Your literal first lesson (free on the landing page, no signup) is the four tones, then tracing 你 and 好 in correct stroke order.

Which level do you actually need?

For travel and daily-life conversations, HSK 3 is the honest target — it is where you stop performing memorized phrases and start improvising. Degree programs taught in Chinese commonly require HSK 4 (frequently for science and engineering) or HSK 5 (frequently for humanities and business); check the specific program. For professional work in a Chinese-language environment, HSK 5–6. And if your goal is speaking, know that you don't have to wait for any of these: with the right method you can hold real conversations with a native speaker from your first weeks — that's the comment + question method, and GraphChinese trains it from lesson one.

How the levels fit together — and why gaps compound

Chinese is unusually dependency-heavy. Tones and pinyin hold up the characters, characters hold up the words, words hold up the grammar patterns, and the patterns hold up everything you want to say. An HSK 4 sentence is built almost entirely from HSK 1–3 material plus one or two new elements; if the old material isn't automatic, the new sentence is illegible. This is why "I finished the HSK 3 book" and "I have mastered HSK 3" are different claims — and why cramming a level for the exam so often collapses the month after.

In GraphChinese: all 743 topics live in one dependency graph. A topic stays locked until every prerequisite is proven mastered, spaced reviews keep old levels from decaying while you climb, and a free adaptive placement drops you exactly at your frontier — nobody re-grinds what they already know. The learning science behind all of this is on the science page.

Frequently asked questions

Is HSK 6 the same as fluency?

HSK 6 certifies comfortable comprehension of long texts and lectures and fluent expression in writing and speech — roughly 5,000 words of active vocabulary, and a genuine mastery milestone. Like any exam, it measures what it tests: educated native speakers know several times more words, and real-world fluency also depends on listening speed and conversational mileage. Treat HSK 6 as the end of the guided ladder, not the end of the language.

What is HSK 0?

Not an official level — it's GraphChinese's name for the foundations every official level assumes: tones, pinyin, stroke order, radicals. Nineteen topics at the base of the graph.

Which HSK level do universities require?

Commonly HSK 4 or HSK 5 for degree programs taught in Chinese, varying by university and field. Check the program's published requirement.

Do the levels build on each other?

Completely. Each level's material assumes everything below it is automatic. That's the core reason GraphChinese exists: the dependency structure is real, so the course makes it explicit and refuses to let you build on sand.

Find your level in minutes. GraphChinese's free adaptive placement tests you down to the topic, then starts you exactly at your frontier. Complete beginner? The first lesson is free on the landing page — no signup. The whole course, HSK 0 through HSK 6, is a one-time $49 for lifetime access.
