Ever wonder what 5000 HSK vocabulary look like. We made a it into little boxes for better visualization.
In the web page, you can tap on any of the squares to turn it “white” – this way you can mark the words that you already know. So your goal is to eventually mark all of them. The ones you marked are saved to your browser’s local storage, so they will remain marked even if you refresh your browser. You can also create a full-size screenshot of your progress with the Full Page Screen CaptureChrome extension.
