Two-part allegorical saying is a short, funny and vivid sentence. It consists of two parts: the first part plays the role of "introduction", like a riddle, and the second part plays the role of "backing", like a riddle, which is very natural and appropriate. In a certain language environment, it is usually said that the first half sentence and the second half sentence can be understood and guessed by "two-part allegorical saying", so it is called two-part allegorical saying.

Two-part allegorical saying is an idiom, which is familiar to the public. Couplets made in this way are two-part allegorical sayings.

Two-part allegorical sayings can be divided into two types:

One is logical reasoning, and the explanation part is the result of reasoning from the previous metaphor part. For example:

Pig eight quit to look in the mirror-not a person inside and outside.

Narcissus doesn't bloom-play dumb.

Dumb people eat coptis chinensis-knowing what disease they have (or "can't say what disease they have")

There is also a kind of homophonic allegorical saying, which adds homophonic elements to the former type. For example,

Nephew plays lanterns-as usual (uncle)

Confucius was moved-all lost (book)

Burning charcoal with a flagpole (sigh)

Shut the knife in the cesspit-literature (smell) and martial arts (dance) are not good.
