Idioms and idioms are the same juxtaposition.
A pause (,) is a pause between juxtaposed words or phrases.
In Chinese, it has two main purposes, separating similar parallel things, usually single words, words or short sentences, in which the pause is shorter than comma.
Commas divide sentences into meaning groups, indicating pauses less than semicolons and greater than pauses.
Comma is the most widely used and flexible, so it is also the most difficult to master.
