Please choose an idiom that appeared in the Spring and Autumn Period and explain its practical significance.

Three people spread the news of a tiger, making you believe that there is a tiger around.

During the Warring States period, when attacking each other, in order to make everyone really keep their promises, countries usually gave their princes to each other as hostages. The Warring States Policy; "Wei Ce" has this record:

Pang Cong, minister of Wei, will accompany Wang Wei to Zhao as a hostage. Before he left, he said to Wang Wei:

"Now there is a person who says there are tigers in the market. Can you believe it? "

Wei Wangdao: "I don't believe it."

Pang Cong said, "If a second person says there are tigers in the market, can your majesty believe it?"

Wei Wangdao: "I have some doubts."

Pang cong added, "if a third person says there are tigers in the market, will your majesty believe it?"

Wei Wangdao: "Of course I will believe it."

Pang Cong said: "It is clear that there will be no tigers in the market, but after three people said it, it seems that there really are tigers." Now Handan, the capital of Zhao, is far away from the capital of Wei, much farther than the market here, and there are more than three people who say that I am. I hope the king can see clearly. "

Wei Wangdao: "I know everything myself."

Pang Cong accompanied the prince back to China, but Wang Wei didn't summon him again.

Cities are places where population is concentrated. Of course there will be no tigers. It is obviously a rumor and deception to say that there are tigers in the market, but many people will often believe it if they don't look at the problem from the truth.

This story was originally intended to satirize Wei Huiwang's ignorance, but later it was extended to the idiom "Three people make a tiger", which is a borrowed metaphor, meaning that sometimes rumors can cover up the truth. For example, to judge whether a thing is true or false, we must carefully examine and think, and we can't hear it from hearsay. Otherwise, "three men make a tiger" will sometimes mistake rumors for truth.

During the Spring and Autumn Period, there was a man named Pore in the State of Qi. He loves to hear those unfounded legends, and then tells others what he has heard with relish. Once, Pore heard about a duck and a piece of meat. He felt very strange and told it to Ai Zi. He said, "There was a man who kept a duck that could lay eggs. This duck can lay more than 100 eggs a day. " Seeing Ai Zi smiled, he added, "That day, a piece of meat fell from the sky. It is 30 feet long and 10 feet wide. " Ai Zi smiled and asked, "Really? Is it as long as meat? " Pore quickly said, "Oh, that's twenty feet long." Ai Zi still doesn't believe it. He changed his tune again: "It must be ten feet long." Ai Zi said, "Who raised the ducks you mentioned? Where did you say the meat fell? " Pore faltered, and finally had to say, "I heard it on the road."

The idiom "hearsay" comes from this story. This idiom means to hear unfounded remarks or rumors on the road and then pass them on to others.

In ancient times, there was a famous archer named Lei Geng in Wei State. His archery is superb, and he hits every shot.

One day, the sky was exceptionally clear, and the king of Wei took Lei Geng and others to the suburbs to hunt. When they came to the suburbs and looked into the sky, after a while, a wild goose flew in from the east. Lei Geng said to Wang Wei:

"Your Majesty, have you seen this wild goose?"

Wang Wei said, "Yes, I saw it."

Lei Geng said confidently, "I don't need an arrow. All I have to do is pull the bow and buckle the string, and I can shoot this wild goose down. "

"Is it true?" Unbelievable, Wang Wei asked in a skeptical tone, "Do you have such ability?"

Lei Geng added, "Then let me try."

Lei Geng didn't take an arrow, but he held a bow in his left hand and a string in his right hand, and only heard a bang. At the same time, I saw the wild goose fly straight, flapped its wings twice and suddenly fell straight from mid-air.

"ah!" Wang Weizhi stared at him and said in surprise, "You really have this ability!"

Lei Geng smiled and explained, "This is not to say that I have good skills, and it is nothing unusual. Because I know that this is an injured wild goose. "

Wang Wei was even more surprised and asked, "How do you know?"

Lei Geng further explained, "You didn't see that he was flying slowly and tired, and his singing was terrible. Flying slowly, this is because it was injured by an arrow, the wound has not healed, and it is still very painful; It's very sad, because it left its companions, and it's lonely and can't get everyone's help. " So, as soon as she heard the string, she was afraid. She flew as high as possible. So hard, the wound opened again and she fell. "
