Saying that a person has the ability and saying that a person has no ability, we all like to use the stomach to say things. Incompetent people can say that he has a big belly and a little ink on his stomach, and he often says that he is full of knowledge and ability to praise who is strong in learning and ability. Where did the full belly of the economy come from at the earliest?
In the Zhou Yi Tun it is said: "Xiang Yue: Yun Lei Tun, gentleman with jinglun." This is the source of the earliest economics seen so far. As we all know, the I Ching is a book of wonders, known for its esoteric interpretations. This gua is tun gua, and the gua is like a tremor (thunder) down the kan (water), which is literally understood to mean that the heavens and the earth were founded, the country was founded, and the talented gentleman should devote all his talents to the cause of the creation of the state.

"Jing" is a common word in ancient times, the classic must-read books at that time can be simply summarized as "jing", in fact, the sutra refers to silk, which is our earliest material that can be used for weaving, and the silk woven is not only a high-grade cloth, but also the best carrier for the past readers to write and record, the disadvantage is that it is expensive and less. Of course, sangma and others can barely weave to make clothes, but it is not suitable for writing. As a result, it is often later extended to be written writing. And lun is a verb, meaning to organize and weave, together, "economic lun" refers to the sorting of silk threads, sorting out the silk, weaving and molding, etc., which is easily extended by everyone as culture, knowledge and thought.
Therefore, the meaning of full belly economy jumps out, which means that someone is learned, skilled, and has the ability to govern the country and the country.
There is also a story about the full belly of the economy. Lang Ying was a person with a lot of works in the Ming Dynasty, the reason is that in addition to his solid foundation of studious skills, it is also that he has no distractions, is not in good health, does not mix with the official field, specializes in studying at home, and is a famous bibliophile. He wrote a "Seven Revision Drafts", which is also a large tome of dozens of volumes, and the compilation of classification examples is innovative, and the content mostly involves some historical events and customs and trivia of the current and previous dynasties.
In the article "Things • Prodigy Pairs", it is told that the famous ministers Li Xiya and Cheng Huangdun during the Ming Yingzong period were both famous prodigies, and they were cordially received by Yingzong when they were still prodigies during the Chenghua years. At that time, the tribute crabs sent by the Zhili region arrived, and Yingzong was inspired to come, and there was an upward link: "Crabs are full of armor", Cheng Huangdun is right for "Phoenix All Over the Body Article", and Li Xiya is right: "Spiders are full of belly economy".
If you look at the degree of the battle, Li Xiya's is better, the original meaning and metaphor can be matched, and it is interesting. Of course, the different lower links also stated the ambitions of the two and the focus of future career choices. Cheng Huangdun was a well-known scholar who had been engaged in a lifetime of learning, while Li Xiya was keen to govern the world and became the cabinet elder.
In the evaluation of the "Seven Revision Drafts", "occasionally a pair, and the lifelong career can also be seen", which is quite reasonable.
