In academic research, the repeated use of data will lead to academic misconduct, such as self-plagiarism, data fraud and so on. If two papers use the same data, the contribution of these data will only be calculated once, which will lead to misleading research results. Use different data in two papers, or quote the data used in the first paper in the second paper, and indicate the source. If it is really necessary to use the same data in two papers, it should be clearly stated in both papers, and it should be noted in the papers that the reuse of these data is fully authorized and licensed.
