What is the method of representing an abstract thing with a concrete thing?

It's called analogy! Analogy is an ancient method of cognitive thinking and speculation, which is to classify unknown or uncertain objects with known objects, and then make guesses and analyses about unknown and uncertain objects.

Analogy. Analysis:

Analogy is one of the oldest methods of cognitive thinking and speculation, which is to classify and compare unknown or uncertain objects with known objects, and then make guesses about unknown or uncertain objects. If the unknown object does have more similarities with some known counterpart, then the analogy has some cognitive value, and taxonomy evolved from the analogy method.

A method of reasoning that allows it to be inferred that things similar to it should also have certain properties that a class of things have. The conclusion must be tested experimentally, and the more properties the analogy has in common, the more reliable the analogy conclusion is. An analogy is the comparison of some identical aspect of a class of things, proving the truth or falsehood of another thing by the truth or falsehood of that thing.

This is a method of using the form of analogical reasoning to make an argument.

The method of using a concrete representation of a concrete thing, an abstract thing, is called analogy. In other words, abstract things can be simplified through analogy, so that people have a preliminary idea.

The use of a concrete thing to represent an abstract thing is called a figure of speech metaphor. Because only by using figurative rhetoric can it be more concrete, visualized.

I think it's abstract analysis, that's the one method.

A concrete mistake, his cousin an abstract mistake, his method is a kind of imitation, this is also a good form of imitation.

Using a concrete thing to represent an abstract thing is called metaphor or analogy.

Symbolism. Symbolism is based on a certain connection between things, with the help of a specific image of someone or something (symbolic body) to express a certain abstract concept, thought and emotion. It can make the article lofty and subtle.

The proper use of symbolism can turn some relatively abstract spiritual qualities into concrete and perceptible images, so as to leave a deep impression on the reader, give the article a deep meaning, and leave the reader with room to chew on the aftertaste.

Chu. "Ode to Orange" is an ancient masterpiece that uses the technique of comparison throughout. Since then, it has become one of the common techniques in poetry and prose.

It is generally used to praise the beautiful things of Mu Zen, and the author's pursuit of the ideal realm, but sometimes it can also be used to satirize ugly things and criticize unreasonable phenomena.
