Time constraints refer to the evaluation of any theoretical results, and there should be a considerable amount of time to qualify for the preliminary evaluation. The theoretical results of the humanities and social sciences generally have to pass more than five years of testing to get a fair and effective evaluation. Space constraints mean that a certain number of evaluators who have no interest in the author should be selected, for example, evaluators outside the school, provinces and cities, or even foreign countries, to ensure the objectivity and fairness of academic evaluation.
