The Chinese word 画龙点睛 is formed directly from a specific historical anecdote where a painter completes a dragon painting by adding the pupils to its eyes, which is said to bring the dragon to life; the characters sequentially represent the actions and objects from this story: 画 (to draw), 龙 (dragon), 点 (to dot), and 睛 (eyeball/pupil), combining to convey the concept of adding the vital finishing touch.
