Papers need to be reviewed for publication. One thing is that the review of the content of the paper is inconsistent with the actual situation and it is easy to fail. Some people think that small changes in data should not be found. You know, the publication of a paper represents the author's academic achievements. Once there is something wrong with the paper data, it can only show that the author's academic level needs to be improved and the research is not rigorous enough, which has an impact on the author's reputation. Data fraud must be investigated, because all papers that need to be published will be reviewed, and the review is not so easy to pass.
