Before, when searching for MDPI journals, all I saw were criticisms, saying that they were low-quality and could be published with money. I submitted an article myself and observed several issues before and after. I felt that the quality of the source material was uneven. Some felt like they were from undergraduate students, with no charts or tables even on the last 8 or 9 pages. Some articles were lengthy, spanning over 30 pages, and included submissions from domestic and defense universities such as National University of Defense Technology, Nanjing University of Aeronautics and Astronautics, and Beihang University, as well as some research institutes. There were also submissions from Tsinghua University, University of Tokyo, Hong Kong Polytechnic University, and even Stanford University.

In summary, the speed is fast, the efficiency is high, but the reputation is average.

For those in difficult fields to publish articles, this is quite suitable. It is also not bad to be in the 2020 JCR Q2.

There are many options for popular field journals, some with noble "academic pursuits." There is no need to criticize these journals just because they are not top-tier. Publishing in a prestigious journal does not mean contributing more to society than a janitor, and publishing low-quality articles does not necessarily mean being despicable. Within the limits of reason and legality, just focus on doing one's own work well.

The review process was fast. I submitted the paper on December 23, 2022, and received the first major revision comments on January 18, 2023. I then submitted the revised manuscript on January 22. On January 27, I received the second round of revision comments, and on February 4, I resubmitted the revised manuscript. On February 13, it was accepted, and after proofreading, it was published online on February 15.

Previously, I have also submitted to other EI and SCI journals, including the English version of the Journal of Aeronautics. Overall, I don't feel it was difficult to submit, and the requirements were not as strict as CJA. The reviewers were responsible and provided objective comments. Although the publication fee was expensive, isn't it normal to pay for OA? Otherwise, how can journals generate income if not through fees? It may be due to the high number of submissions, but the increase in impact factor indicates that high submission volume does not necessarily mean a decrease in quality. I don't understand why there is a warning.
