The magazine submitted for review has been submitted for review, which means that it is more challenging for external experts to review the core content of the article than the preliminary review and final review. External audit experts are all experts, scholars or professors in this field. They have done in-depth research on this topic and accumulated a lot. Perhaps the external audit experts can better see the true level of an article.

Blind trial is relatively difficult. Issued by the school, mostly to other provinces, and the names and tutors' names are hidden. You don't know where your paper was sent, and the teachers there don't know where it came from and whose students it is, so the blind test is more objective and takes about one and a half months.

Most of the external audits are sent out by the department itself. Although the names of students and tutors are also hidden, they are sent to brother colleges with good relations in the province, so it is relatively less strict than blind audits. It takes about a month to a month and a half.

What do you mean by blind trial and external trial? What is blind review? It is a new system for organizing expert group evaluation this year: anonymous submission, which means that the evaluation tutor does not know who the author of the paper is.

What is external review of papers? This is a measure of postgraduate education reform. External review of papers is to send papers anonymously to well-known experts in the industry and ask them to review and give their opinions. Many times, they will meet very picky experts and ask many questions. Whether it is a blind test or an external test, it is uncertain and random.
