   In the center is the writing area, with gray auxiliary lines marking the horizontal and vertical boundaries. Writing should not extend beyond this area. The blue horizontal line represents the baseline.
   
   Below the writing area is the character information: character index, character display, and corresponding Unicode code.
   
   At the bottom are the function buttons and menu: The "Undo" button deletes the last stroke, the "Clear" button deletes the entire character, the "Settings" button opens the settings menu, and the "Next" button moves to the next character.
   
   The settings menu includes: settings for pen width, color, and type. The types include brush, wedge, round, and rectangular. The prompt font is the font for the hint text at the bottom of the writing area. You can choose from serif (Songti), sans-serif (Heiti), or monospaced font (uniform width for English characters). When the "Variable Width" option is selected, the pen width will change depending on the writing speed. Selecting the "Auto Next" option will automatically finish and move to the next character after 1 second of completing the current stroke.
