Single-knowledge idiom

Quite critical (pinyin: yīyèzhèqi) is an idiom in China, which comes from "Huai Nan Zi Shuo Shan Xun". The original meaning of "quite critical" is to know the arrival of autumn from the falling of a leaf, and then show the development trend and result of the whole situation through individual subtle signs; Generally used as an attribute in sentences.

The idiom story is as follows:

At the end of the Warring States period, there was a hermit named Tian Jizi who lived in the deep mountains. He planted a small piece of land near his home and stayed there all the time except buying daily necessities. One day, Zhao's nobles came to the mountain to play. He heard from people nearby that there was a hermit on this mountain, so he came to have a look.

During the chat between Zhao Zheng and Tian Ji, he found that although Tian Ji seldom went down the mountain, he knew the world events and could speculate what would happen in the future. He couldn't help but ask curiously, "sir, you don't have to go down the mountain, but you can know what's going on in the world." Is Mr. Murphy a fairy or a powerful divination master? "

At this time, I saw the cat laughed and said, I am neither a fairy nor a fortune teller. I will only infer the subsequent development and results from subtle signs. Just as we see the leaves fall, we know that autumn is coming and the weather will get colder and colder. Seeing that Qin destroyed South Korea, I knew that Zhao could not be saved.

Sir, listen to my advice, don't go back to China, stay here! Soon after, Qin did destroy Zhao, and then destroyed other countries one after another.
