Both big papers and small papers are academic papers, and they should follow the principles of academic integrity and intellectual property law. If the contents of big papers and small papers are identical or repetitive, it will be regarded as plagiarism, which will have a negative impact on the author's reputation and future academic development.

When writing a big paper, you can learn from the content of your own small paper, but you must quote and annotate it appropriately to show that you have considered the work of the small paper instead of copying and pasting it directly. In addition, big papers should contain more innovative contents and research results to show their academic value and contribution.
