Memory is about cues, not answers
You may have forgotten 'jury' — but seeing 'jury pool' or the original sentence 'The jury pool was selected...' instantly brings it back. Your brain stores cues, not translations. Isolated symbols are forgettable; information is memorable. Memory works through context, not through isolated answers.
Search beats repetition
Flipping a card that says 'taint → 污染' tests whether you can recall a symbol. Searching 'taint' and returning to the article where you read it reactivates the entire information network around the word. Quality repetition is not seeing a symbol more times — it is re-experiencing the same information in a familiar context. Most learners lack a language environment, so sustaining heavy reading input is hard. Without a way to return to what you already read, you are always starting from scratch — spending the same effort on new articles instead of deepening what you already partially know.
Understanding is the shortcut
When background information is clear — cultural references, implied arguments, historical context — the word attaches to meaning automatically. You think you are reading, but you are actually acquiring language. Memorizing words is the byproduct of understanding information, not a separate task. AI-powered explanations make deep understanding affordable.
