Citation of a paper is to take other people's conclusions as a reference for writing your own paper.

There are three ways to quote the correct paper.

Method 1: When quoting others' words, you can't use colons, but you can't directly quote the author's full text. Express it in your own words. Can be summarized and simplified.

Method 2: Introduce commonly used keywords. For example, inserting a sentence or two from the basic theory of colleges and universities into the direct evidence of data information and examples can make the language of this part of the paper powerful. At the same time, references can be used with data information and examples. It should be noted that this reference should be introduced and annotated one by one.

Method 3: Introduce a relatively large paragraph in the paper. It can be distinguished according to different font styles. Even the front, back, left and right space characters should be commented one by one. At the same time, if you don't distinguish between different font styles, you can use colons, but the quotation marks should not be too long, preferably not more than three words.
