What is the connection between mantis catching cicada and the attack of Chu by the prince of Wu? What is the reason? Talk with real life.

The king of Wu has always been bossy, and it is difficult to convince him.

On one occasion, the King of Wu was ready to attack the State of Chu. He summoned his ministers and announced that he would attack Chu. Hearing this news, the ministers began to whisper to each other, 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 prince heard the ministers whispering at the bottom, and seemed to have objections, so he snapped:

"You don't have to talk about it. I have made up my mind. No one can shake my determination. Whoever insists on stopping me will never spare me! "

Ministers looked at each other, who also dare not say anything, and hurried back to the DPRK.

There is an honest young man among the ministers. After the lawsuit, he was still restless. He believes that national security cannot be ignored because of himself. The minister paced up and down the garden, and his eyes accidentally fell on a cicada in the tree. He had an idea at once.

The next morning, the minister came to the back garden of the palace. He knew that the former prince of Wu would come here for a walk every morning, so he specially waited here.

After about two hours, the prince of Wu, accompanied by ladies-in-waiting, came to the back garden. The minister pretended not to see the king of Wu and stared at a tree.

The prince saw the minister's clothes wet with dew, but he didn't seem to notice. His eyes were fixed on the branches and he had a slingshot in his hand. He patted him on the shoulder in surprise 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? "

Minister deliberately pretend to have just seen the prince, quickly make amends:

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

The prince waved, but curiously asked:

"What the hell are you looking at?"

The minister said:

"I just saw a cicada drinking dew. I didn't expect a mantis to bow its head and prepare to prey, and mantis didn't expect a yellowbird to aim at itself. Yellowbird thought that the slingshot in my hand would kill it ... "

The prince smiled and said:

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

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

This idiom means short-sighted, thinking only of calculating others, and not expecting others to calculate him.
