Character by character
Origin and story
LegendThe familiar legend of the painter Zhang Sengyao is recorded in Zhang Yanyuan’s Lidai Minghua Ji (歷代名畫記), volume 7. At Anle Temple in Jinling, Zhang painted four white dragons but left their eyes unfinished. He warned that adding the eyes would make them fly away. When onlookers insisted, he added eyes to two dragons. In the legend, thunder and lightning broke the wall, and those two dragons rose into the clouds; the two without eyes remained.
This is a story about the almost magical power of a decisive finishing detail, not a documented event involving real dragons. An earlier related motif appears in Wang Jia’s Shiyi Ji (拾遺記), where giving eyes to lifelike artworks brings them to life. Today the idiom praises a small but crucial addition that makes an entire piece of work more vivid or effective.
In everyday life
你在报告结尾加的那个例子，真是画龙点睛。
The example you added at the end of the report is just the finishing touch it needed.
Use this to praise an addition that improves the whole work, rather than just any final task.
