Memory tip

A flat illustration of a steaming bowl of food, with the kanji 沸 ("boil") drawn into the picture.

Picture a steaming bowl of food: that is what 沸 means — boil. Now find the part that anchors it in the character itself, 氵 (water) — three drops of water running down the left edge, and beside it 弗 (not / currency mark) — two strands pulled taut and crossed, straining against each other. Drop that part into the picture and the shape stops being something separate to memorise.

Writing Tips

  • Follow the order strictly: top-to-bottom and left-to-right. Correct order makes the shape balanced and natural.
  • Keep each stroke in one smooth motion — don't lift the pen in the middle of a stroke.
  • Close enclosing strokes cleanly so the character does not look open or broken.
  • Common mistake: drawing strokes bottom-to-top or right-to-left. Even if the result looks similar, the wrong order shows in handwriting and makes it harder to read.
