The content comes from the site's confidential website
The common or commonly used documents in our daily life include ancient books, journals, academic papers, etc. The main way to find these documents in China is CNKI, Wanfang and other large-scale websites However, these websites charge for downloading articles. The fees charged by these websites are mainly used for platform maintenance and copyright acquisition of some papers.
However, the copyright purchase is generally not purchased directly from the author, but purchased in bulk from the journal, so even if the author himself wants to download his own article, he still needs to pay the website.
As for the issue of paper copyright, few authors make profits from publicly published papers. Instead, you have to pay fees to the journal for publishing the article. The benefits of obtaining the literature are obtained by the journal, and the author does not make any profit.
does not have much motivating effect on authors, but instead limits the dissemination of knowledge. Generally, authors sign relevant agreements with journals when their papers are published. Who owns the copyright depends on what is stipulated in the agreement. The copyright ownership of papers is very complicated, and there are many disputes at home and abroad.
And many well-known scholars and academic figures support open and free access to literature.

Conclusion
Confucius said, "I can tell the etiquette system of the Xia and Yin dynasties, but the descendants of these two dynasties, Qi State and Song State , cannot prove my words, because of the literature (at that time, it refers to people who are familiar with etiquette stories and classics) "Too little, if there are enough, you can prove my words." This is Confucius's satire on later generations for violating etiquette and not following the ancient system, and also illustrates the importance of documents. It is also worth studying how
can obtain literature efficiently and at low cost before the paywalls established by major databases.
