The idiom "know everything" is used to describe a person's rich knowledge and ability to deal with major problems. If we study its original meaning, the word "economy" originally meant to arrange silk thread and extended to planning and management. For example, The Book of Rites. The Doctrine of the Mean says: "Only when the world is sincere can we manage the great classics of the world." It means that only sincere people can govern the world well. In addition, for example, the word "economy helps the world" also means this. As for "full", it means "full stomach" For example, "Zhuangzi Xiaoyao Tour" said: "Wren nests in the deep forest, the only branch; The mouse drank the river, but it was full. " Wren nest in the depths of the forest, occupying only one branch. The squirrel drank the water from the river, and then drank it again, but it was only full. Later, because the stomach is the largest space for the human body to fill food, it is easy to use "fullness" to express the meaning of filling the body. For example, "full of articles" and "full of talents" all describe people as very knowledgeable. For example, "full of complaints" and "full of worries" have the same usage. But the structure of these words is "know-how" followed by a noun phrase, so the word "know" of "know-how" should be changed from a planned verb to a noun, meaning "know-how". Some people think that the idiom allusion of this idiom comes from Yijing, Tungua and Xiangzi: "Xiangyue," Clouds and thunder, Tunzi. A gentleman helps. Confucius once wrote Ten Wings to explain the Book of Changes. Wing is an auxiliary explanation, and iconography is one of them, which is used to explain the personnel truth contained in hexagrams. Tungua is composed of "On the Mountain under the Earthquake": "Zhengua" is below, symbolizing thunder; "Kangua" symbolizes the water in the world. The water on the thunder didn't make rain, so it was like a disaster, but after the thunder, it would rain. This phenomenon is just like the difficulties encountered at the beginning of many things. When the difficulties are solved, the progress will be smooth. So Confucius asked the gentleman to learn the truth of planning and managing things from the hexagrams. In Xiangci, "gentlemen learn economy" means "gentlemen learn economy". The word "full classics" appeared earlier in the literature, such as Song Hongyan's poem "Twelve Rhymes of Wen Shichuan's Suggestion on Zhangzhou": "Full classics, pen leisure (occasionally) contains dew rain." It is said that Dr. Ishikawa's advice is "full of knowledge, and the article contains rain and dew." Tolerance of rain and dew means taking care of the people; "erudition" means that you are rich in knowledge and can be superb.
