Does The Scared Bird come from a historical story?

Yes, it comes from: Chu Ce IV of the Warring States Policy; "Jin Shu Jian Wang Zhuan": "Pride is easy to move, but it is difficult to decide if you are surprised."

Explanation: Birds frightened by bows and arrows are not easy to settle down. Metaphorically, a frightened person will be very scared when he hears the slightest sound.

This is the story of a frightened bird: aliens, Lei Geng and Wang Wei are under the Beijing platform, looking up at the bird. Lei Geng called Wang Wei and said, "I bow for the king and make a wig." Wang Wei said, "But can you shoot that far?" Lei Geng said, "Yes." Once, geese flew from the east, and Lei Geng sent them down for nothing. Wang Wei said, "But can you shoot that far?" Lei Geng said, "This is evil." Wang said, "How do you know?" Yes, he said, "it flies slowly and cries sadly." Therefore, those flying horses are both painful and painful; Those who mourn for a long time lose the group, so the sores have not stopped, and the heart-pounding has not arrived. As soon as you hear the strings, you will fly high, so the sores will fall. " I hope this helps.
