画龙点睛 huà lóng diǎn jīng
Paint four dragons, add two eyes — and the wall explodes.
The short answer
画龙点睛 means to paint the dragon's eyes: the small, final touch that makes the whole thing come alive. The English cousins are “the finishing touch” and “bringing it to life”.
The story
The legend belongs to Zhang Sengyou, the great painter of the Liang dynasty. Commissioned to decorate a temple wall in Jinling (today's Nanjing), he painted four dragons of astonishing life — and no eyes. When pressed, he warned that dotting the eyes would let them fly away. The crowd laughed; he relented enough to dot two.
Thunder cracked the wall, the two completed dragons climbed into the sky, and the two eyeless ones stayed on the plaster. Whether or not any wall ever behaved this way, painters have been hearing about it for fifteen hundred years.
What it means today
画龙点睛 is the standard praise for the decisive detail: the one sentence that makes the essay, the chorus that makes the song, the single prop that makes the room. The work was already a dragon — but a still one, until the eyes.
The idiom implies restraint as much as flourish: the eyes are tiny. It is the respectful opposite of 画蛇添足 — there the addition ruined a finished thing; here it finished a living one. Knowing which your draft needs is most of the craft.
How to use it
Typical shape: 结尾这句话真是画龙点睛, “that final line truly dots the dragon's eyes”. It also works as a verb phrase: 这笔点睛之笔.
