Molly Show: Why did artist Zhang dare not draw the pupils of a dragon?

huà lóng diǎn jīng means to bring the painted dragon, or Loong, to life by putting in the pupils of its eyes.　

This idiom is related to the story of Zhang Sengyao, a painter dating back about 1,500 years.　

Once he added eyes to the dragon he drew, it would come alive and fly away.　It is often used to describe the effectiveness of a writer or speaker who uses a few key sentences to bring a topic alive. It is also used to praise others for their creative genius.
