He said: If you click your eyes, the dragon will fly away. Others thought this was ridiculous, so he lit the dragon's eyes. After a while, there was a thunder and lightning, which destroyed the wall. The dragon flew away on the clouds, but the dragon without the eyes was still there. This mythical story describes Zhang Sengyao's superb painting skills.
