Academic journals are different from ordinary entertainment magazines. They are platforms for academic exchanges. The author publishes papers to spread his academic views and achievements, not to make money. Due to the small circulation of academic journals, it is much more difficult to edit and review manuscripts than other types of magazines, and academic journals at home and abroad contribute less.

Due to the small number of academic journals at present, it can not meet the needs of graduation defense and title evaluation. After paying, it may not be published. In order to ensure the quality, a good periodical only sets aside a part of its pages to make extra money.
