What is the connection between the mantis catching cicadas and the attack of the king of Wu on Chu? What is the reason? Talk about it in connection with real life.

the king of Wu has always been bossy, and it is very difficult to persuade him.

once, the king of Wu prepared to attack the state of Chu. He summoned his ministers and announced that he would attack Chu. On hearing the news, the ministers began to whisper, because everyone knew that Wu's current strength was not strong enough, so it was imperative to save your strength and make the country rich and strong first.

The King of Wu heard the ministers whispering in the bottom, and seemed to have objections. He stopped sharply:

"You don't have to talk about it. I have made up my mind, and no one will try to shake my determination. If anyone insists on stopping me, they will never spare me!"

The ministers looked at each other, and no one dared to say anything, so they hurried back to the DPRK.

among the ministers, there is an upright young man. He still has no peace of mind after going to court. He thinks that he can't ignore the security of the country because of himself. The minister paced up and down in his garden, and his eyes accidentally fell on a cicada in a tree. He immediately had an idea.

Early the next morning, the minister came to the back garden of the palace. He knew that the former king of Wu would walk here every morning, so he deliberately waited here.

After about two hours, the King of Wu, accompanied by the ladies-in-waiting, came to the back garden. The minister pretended not to see the king of Wu and fixed his eyes on a tree.

The king of Wu saw that the minister's clothes had been wet by dew, but he seemed unaware of it. His eyes were fixed on the branches and he was still holding a slingshot in his hand. He patted him on the shoulder in wonder and asked,

"Hey, what are you doing here early in the morning? Why are you so absorbed that you don't even know that your clothes are wet? "

The minister deliberately pretended as if he had just seen the King of Wu, and made a quick apology.

"I just looked at the cicada and mantis in the tree, but I didn't know the arrival of the King. Please forgive me."

The King of Wu waved, but asked curiously,

"What are you looking at?"

The minister said,

"I just saw a cicada drinking dew, and I didn't realize that a mantis was bowing its head to prey on it. The mantis didn't think that a yellowbird was aiming its mouth at itself, and the yellowbird didn't think that the slingshot in my hand would kill it ..."

The king of Wu smiled and said,

"I see, don't say any more."

finally, the king of Wu gave up the idea of attacking Chu.

This idiom is used to describe short-sightedness, only thinking of calculating others, but not expecting others to calculate him.
