The validity of the published papers depends on the provisions and requirements of the title evaluation. Generally speaking, articles published within 3-5 years before applying for this title are valid. However, it should be noted that the title of the paper cannot be reused, and the paper applied for intermediate title cannot be reused when applying for senior title, so the title of the paper needs to be published again. Therefore, when preparing the topic of the paper, we must plan ahead and prepare and publish it according to the review requirements and time nodes, so as to ensure the effectiveness of the paper. At the same time, we should pay attention to the quality, academic level and research depth of the paper to meet the corresponding standards in order to improve the success rate of the paper.
