Using Spaced Repetition for Chinese Vocabulary

Spaced repetition is a review method that shows a card again around the time you are likely to forget it. Anki is one of the best-known flashcard apps for doing this: you create cards, review them, and the app schedules the next review automatically.

The scheduling part is the easy part. What decides whether spaced repetition works for Chinese is the card itself. A card that only pairs a character with an English word will train you to recognize it on a page and leave you silent when you have to say it.

Why Chinese Needs More Than a Two-Sided Card

English spelling is famously irregular, but it still points at the sound: you can read an unfamiliar word aloud and be roughly right. A Chinese character gives you nothing to go on. And even once you know the syllable, the tone is a separate piece of information you can forget on its own.

So a Chinese word is really four things you can fail independently:

the character, which you must recognize and ideally write
the syllable in pinyin
the tone on that syllable
the meaning and how the word is used

If your card only tests the fourth one, the other three quietly rot.

What a Good Card Contains

A useful card for 学生 (xuésheng) should include:

Chinese: 学生 (xuésheng)
Meaning: student
Example: 我是学生 (wǒ shì xuésheng).
Audio, or a link to a dictionary entry with audio

Add the example sentence even when the word seems obvious. 提高 (tígāo) translated as “raise, improve” tells you almost nothing; 提高水平 (tígāo shuǐpíng), “raise your level”, tells you what it attaches to. Pulling examples straight out of a dictionary entry is the fastest way to build this habit — see making the most of dictionary example sentences.

Review in Both Directions

Recognition and production are different skills, and only one of them is tested by a Chinese-to-English card.

Chinese to meaning — for reading. You see 问题 (wèntí) and recall “question, problem”.
Meaning to Chinese — for speaking and writing. You see “question, problem” and have to produce 问题 (wèntí) with the right tones, out loud, before flipping the card.

The second direction is harder and slower, so many learners skip it and then wonder why their listening and speaking lag behind their reading. If you are short on time, apply production cards only to the words you actually expect to use.

Make Tones Part of the Test

Tones are the piece learners most often let slide, because a card marked “correct” in your head can still have been said with the wrong tone. Two fixes:

Say the answer out loud before you reveal the card. If you only think it, you cannot tell whether you knew the tone or guessed it.
Build minimal-pair cards for words where the tone carries the whole meaning: 买 (mǎi), “buy”, against 卖 (mài), “sell”. Getting these two wrong in a shop is a real mistake, not an academic one.

If the tone marks themselves are still hard to read, the tones guide and the pinyin tone color tool are a faster way to fix that than more repetitions.

How Many New Cards a Day

Reviews accumulate. Every new card you add today comes back several more times over the following weeks, so your daily review load ends up several times larger than the number of new cards you add each day. Ten new cards a day is comfortable for most people; twenty is sustainable only if you can reliably sit down for a substantial review session every day, including the days you do not feel like it.

The failure mode is predictable: a burst of enthusiasm, a hundred cards added in a weekend, an unmanageable backlog by Thursday, and the app abandoned. It is better to add five a day for a year than fifty a day for a fortnight.

When a Card Never Sticks

Some cards fail again and again. Repeating them harder does not help — the card is the problem, not your memory. Usually it is one of these:

The card tests too much at once. Split it. One card, one thing.
The example is useless. Replace it with a sentence you could imagine saying yourself.
Two similar words are interfering. 觉得 (juéde), “to think, to feel that”, and 感觉 (gǎnjué), “feeling, sensation”, share a character and overlap in English translation, so they swap places easily. When the contrast itself is the thing you need to learn, that is the one case where putting both on a single card beats fighting them on two.
You do not need the word yet. Delete it. A word you have never met outside your deck is not worth ten failed reviews.

Feeding the Deck from HSK Vocabulary

Rather than adding words at random, work from the official list for the level you are preparing for. The HSK word browser lets you star words by level and review them, and the per-level word pages — HSK 1 through HSK 6 — list words with pinyin and an example sentence you can copy straight onto a card. For deciding which words within a level deserve your attention first, see memorizing HSK vocabulary.

Words you actually met while reading or listening are the best candidates of all — they come with the context already built in.

Summary

The scheduling algorithm is not the hard part; card quality is.
Include character, pinyin with tone marks, meaning, an example, and audio.
Test recognition and production separately, and say answers out loud.
Keep new cards to a number you can still face on a bad day.
Fix or delete cards that keep failing instead of grinding them.
