Hysteria Classification

First, harmonic category. For example:

Empty coffin out of the burial - eye (tomb) in no one.

Confucius moving - net is lost

This type of hysteresis is the use of homophonic or near-sound words in harmony, by the original meaning of the derivation of the required another meaning. It often takes a few turns to realize the meaning of this type of hiatus, which makes it all the more interesting. Some books include it in the category of "puns", and for good reason.

Second, the metaphorical category. For example:

To move wood in the alley - straight to the point.

Cold water hair pasta - not much progress.

This kind of hysteria uses objective or imaginary things as analogies. If you know something about the characteristics and circumstances of the thing you are comparing, you will naturally be able to comprehend the "riddle" of the second half of the paragraph.

Third, the metaphorical category. Such as:

Bull shoulder foot - irresponsible.

Rats on the street - everyone shouting.

This kind of hysteresis is to use some kind or some objects and animals as a metaphor.
