Zhang Sengyou was a famous painter in Liang Dynasty. Once, the emperor ordered him to draw dragons on the wall of anrakuji in Jinling. Soon, two lifelike dragons appeared on the wall. At this time, the emperor found that two dragons had no eyes, so he asked Zhang Sengyou why. Zhang Sengyou replied, "You draw your eyes and they fly away." People didn't believe it. The emperor insisted that he draw eyes, so Zhang Sengyou had to draw eyes for one of the dragons. Lightning and thunder flashed in an instant, and the dragon really flew away.
