Please explain what simile, metaphor, metonymy and pun are, and give examples.

Simile: A clear metaphor is a rhetorical device, which connects two different things with certain features. The simile is expressed as follows: a is like B.

For example, snowflakes fly like goose feathers.

Metaphor: Metaphor is the simultaneous appearance of ontology and vehicle, and the relationship between them is consistent in form. It is said that A (ontology) is (metaphor) B (vehicle). Metaphor is usually expressed by words that express judgment, such as yes, yes, success, becoming and becoming. Metaphor is also called metaphor.

For example, she is a night pearl, which radiates brilliant light in the dark night.

Metonymy: When you speak or write an article, you don't directly say the person or thing you want to express, but borrow the person or thing closely related to it. This rhetorical method is called metonymy. What is replaced is called "ontology" and what is replaced is called "borrowing". When "ontology" does not appear, it is replaced by "borrowing body".

For example, the green hills on both sides of the strait are opposite, and the solitary sail is a part of the whole.

Pun: Using the polysemy of words and homonymy (or homonymy) conditions, deliberately make a sentence have double meanings, that is, pun.

For example, it is clear that it is winter all around, and it is cold and air-conditioned. Lu Xun's Kite

"Cold weather" and "air conditioning" refer to the weather and also to a conservative society.
