Mr Li is a good painter. He likes painting animals. One day he drew a beautiful dragon without eyes. Mr Zhou looked at the picture and said, "The dragon has no eyes. It isn't a good picture." But Mr Li smiled and said, "If I add eyes to the dragon, it will fly away." Mr Zhou shook (摇) his head and said," It is ridiculous (荒唐的)! I don't believe (相信) you." Mr Li wasn't angry. He held the paintbrush and added eyes to the dragon. The dragon really flew away.
