Citation is a scientific dialogue and information method that the author thinks is "useful" for his own research, but it also shows that the meaning of citation is not simple, and it is not just "quantitative" and "objective" as many people think. The first is the author's "subjective" judgment, but how many authors have such "subjective" judgment, and the "data" cited by them is "objective". It is both qualitative and quantitative.

Quoting is to prove and explain your own ideas with other people's views, so you must be loyal to your original intention. Whether you quote the original text or the original intention, you should make a complete statement. Especially when paragraphs quote the original text and original intention, they can only be quoted if they are truly understood and fully mastered. You can't just take a few words without chewing to decorate the facade, and you can't take them out of context for some purpose.

Citation is an auxiliary means of argument, and under no circumstances can it completely replace the idea to be expressed by quotation. There is no problem to use quotations in a paper, but if there are too many quotations, it will easily make the article messy, affect the coherence and integrity of the main content, and is not conducive to the expression of ideas. At the same time, a series of tired calves are other people's things, which will also cause readers' doubts and unhappiness. For a good article, you should use your own language as much as possible. Only when it is necessary to quote, when it is really effective, or when it is not effective to explain in your own words, or when words and convincing evidence are not enough to explain the problem, or when it is necessary to demonstrate. It is generally unnecessary to use it. The so-called accuracy means to be few and appropriate, and to use the most wonderful and appropriate quotations for the most critical points of quotations.
