The composition group of Chang 'an University requires that only an average score of 79 points can be answered.

Simply put, blind evaluation of papers is to anonymize the authors and reviewers, so that they can't know each other's information to review papers. This is a blind review. There are generally two kinds of blind auditing: internal auditing and external auditing. Internal audit is to send the papers to the relevant institutions of the school or the sister school or cooperative school of the school for audit. External audit is to give the paper to a special school for external audit. Regardless of internal audit and external audit, the author and tutor of the paper are anonymous, which can increase academic fairness and rigor.
