Why you forget Chinese words

You forget because memory does not store hanzi like a hard drive. Every hour you skip retrieving 问 (wèn, to ask), the trace weakens. Ebbinghaus measured that loss with nonsense syllables. The graph is the forgetting curve. It is not a verdict on your ear.

Reading the list again does not cut the curve. Rereading is recognition. The exam and the street ask for retrieval: you hear a price and must know whether it was 四 or 十. If you only look, your brain ticks “I have seen this.” The next day you cannot pull it out.

That is the “I knew it yesterday” feeling. Yesterday the card was warm. Today the interval has already cooled it. You did not get slower. You missed the window where a short nudge would still have brought it back.

Classic HSK 1 is about 150 words. The six-level bands summarise as 150, 300, 600, 1,200, 2,500 and 5,000. None of those numbers save you if the gap blows out. One hundred and fifty looks small. With no queue, they flatten just the same.

Chinese makes the problem worse in three ways. Shape: 买 (mǎi, to buy) and 卖 (mài, to sell) look alike. Tone: sì and shí, mǎi and mài. Role: one extra stroke flips who pays. Alphabetic languages fade too. Here the collapse is quieter because the card “almost” matches another one.

Cramming on Sunday lengthens the hole. A short review most days shortens it. Cepeda and colleagues, in Psychological Bulletin (2006), “Distributed practice in verbal recall tasks”, compared spaced and massed practice on verbal recall. The qualitative finding is enough: spacing beats a binge. No invented percentage. The paper sits at doi.org/10.1037/0033-2909.132.3.354.

If you study from a PDF and think “I already know this,” you are measuring familiarity. Familiarity is not retention.

These three pairs sit on the HSK 1 list. The HSK 1 guide says what that level tests. None of them are obscure. That is why it stings when they slip.

First: 四 (sì, four) and 十 (shí, ten). 十 is a cross. 四 is a box with legs. In isolation you can tell them apart. In 四十 (sì shí, forty) and 十四 (shí sì, fourteen) the brain swaps them. A price, a date, or a phone number will not wait while you “remember the lesson.” Miss the tone, the digit changes. Miss the shape, same result. Mark them wrong as soon as you hesitate. Do not “look for one more second.”

Second: 问 (wèn, to ask) and 闻 (wén, to smell / to hear of). Both carry 门. 问 adds 口, the mouth that asks. 闻 adds 耳, the ear. 请问 (qǐngwèn, may I ask) is one of the first chunks you hear. 新闻 (xīnwén, news) arrives just as fast. Skip the radical and both cards melt into “asking or finding out.” Retrieve the radical, not the movie of the lesson.

Third: 买 (mǎi, to buy) and 卖 (mài, to sell). In simplified form, 卖 looks like 买 with a 十 on top. Third tone versus fourth. 买东西 (mǎi dōngxi, to buy things) and 卖东西 (mài dōngxi, to sell things) reverse who hands over the money. A shop dialogue will not forgive the flip. Say the wrong tone and the listener hears the opposite verb.

Writing them once by hand helps you see the extra stroke. It does not replace retrieving them tomorrow with no model.

All three pairs fail for the same reason: you study them together on a list, recognise them together, and retrieve them too late. The interval flattens them. The cure is not an hour of mnemonic tricks. It is pulling each one out again once it is no longer warm.

A blunt rule: if two hanzi share a stroke or a tone, do not add both as new cards on the same day. Let one settle. Bring the other in when the first is already coming back after three days, not after three minutes.

SRS is spaced repetition. You see the front of the card, try to retrieve hanzi, pinyin and gloss, and mark whether it came. If it came, the next interval grows. If it failed, the card returns soon. The system aims at the moment you were about to forget. Not the moment you felt like rereading.

That is not an app. It is a queue. You can run it on paper with Leitner boxes. You can run it in Anki. You can run it in an app that already ships the deck. What is not SRS: flipping 40 new flashcards “until they feel familiar.” That is cramming with a nicer UI.

The useful face at HSK 1 is hanzi. Pinyin goes on the back. If you put pinyin on the front, you are drilling an alphabet, not Chinese. The gloss goes on the back too. Retrieving 买 and saying “to buy, third tone” is the work. Reading “mǎi = to buy” again is not.

One example. 是 (shì, to be) comes up. Do not peek at the gloss. Say the syllable, the tone, and a tiny sentence: 我是学生 (wǒ shì xuésheng, I am a student). If you stall or mix the tone, mark it wrong. Studying it “a bit more because it was close” inflates the streak and poisons the queue.

Mark honestly. “Almost” is wrong. You hesitated between 问 and 闻: wrong. You needed three seconds on 四: wrong. Easy cards relax you and steal slots from the pairs that flatten.

SRS will not teach you to speak. It stops you losing the brick. Speaking, listening, and tones belong in another block. That block is written up in the 20-minute routine. Skip the queue and the rest of the clock is practice on sand.

You do not need to understand the algorithm. You need to stop negotiating the queue. Three to five new words at HSK 1. The rest, due cards. When the queue grows, new cards go to zero. That sentence is the method. The rest is decoration.

Anki runs the same idea. If you maintain the deck, it holds. The problem is not the software. It is the deck.

A shared “HSK 1-6” deck mixes levels, sometimes traditional and simplified, sometimes with no audio, sometimes with sloppy glosses. Some “HSK 1 sentence” decks smuggle in HSK 3 syntax. You have to tag, suspend junk, pick a note type, add sound, and not import three decks at once. That is filing-cabinet work. It is not Chinese study.

Duplicates: 是 (shì, to be) shows up as three different notes. The algorithm thinks you see it often. You actually see three faces, and none of them asks for tone. Clean them up or suspend them.

Audio: with no voice, 买 and 卖 are two drawings. With voice, tone splits them. If your deck has no audio, either add it or accept that the pair will flatten on the street.

Filter: open HSK 1, not the ocean. This site’s HSK vocabulary is 12,432 public words. That is not the exam paper. You will not swallow them. Anki will let you import the lot. That is not a virtue.

Count the time. Twenty minutes building tags are not twenty minutes of Chinese. If you already like tinkering, Anki is still a solid tool. If you want to study, the deck is friction. An app with a queue already built by HSK band removes that step. It is not magic. It is less filing cabinet between you and 四.

Do not add Anki and another streak “just in case.” Two queues are two debts. Pick one queue and pay it.

Fifteen minutes are enough to cut the curve if you do not flood it with new cards. Set a timer.

Minutes 0 to 12: due cards. Hanzi on the front. Retrieve. Mark. If 十 comes out slow, wrong. If 老师 (lǎoshī, teacher) comes first time, good, and do not “review it a bit more for fun.”

Minutes 12 to 15: the new-word cap. Three words, not fifteen. Today, say, 请 (qǐng, please / to invite) and none of the 买/卖 pair if you added 买 yesterday. The pair comes in on another day.

Then you stop. SRS debt is paid across days. An 80-card binge fakes progress and leaves you stiff tomorrow. If the session runs long “because it was going well,” you are back on Motivated Sunday. That Sunday is the one that later forgets 闻.

If you only have 8 minutes, do due cards and zero new ones. That still cuts the curve. If one day you have 40 minutes, do not “catch up” the month. Run the 15 of queue and send the rest to listening or output, as in the 20-minute routine.

Pin the queue to a real slot: coffee, the train, after you leave the phone in another room. The anchor matters more than the app’s colour.

The official exam does not score your streak. The CLEC will not congratulate you for the timer. You can still know whether the interval got shorter.

After 14 days, look at signals, not the streak. One: you hear 四十 and 十四 and do not swap them. Two: the queue is not a red wall every morning. Three: you can say 我要买这个 (wǒ yào mǎi zhège, I want to buy this) without checking pinyin, and 卖 does not slip in. If all three are failing, do not level up. Cut new cards.

A blunt Saturday check, outside the queue: someone says a price with 四 or 十. You write the hanzi. If you miss, that card goes back to wrong on Monday. You do not need a long mock.

If the queue grows without end, you have added too many new cards. The fix is cruel and correct: new cards to zero until it shrinks. That hurts more than a motivation video. It is the only fix.

Do not measure “words seen.” Measure pairs that no longer flatten. 问 against 闻. 买 against 卖. 四 against 十. That is retention. The rest is list tourism.

Chinese Trainer builds that queue by HSK band, with listening and writing in the same account. The inventory is in what’s inside the app. There is one CTA: practice 15 HSK 1 words. HSK 1-2 is free. If after a week you still tell 四 from 十, the queue is doing the work. If not, the problem was not another mascot. It was not retrieving in time.
