The graduation thesis can quote the content of a short paper published by itself, but it can't be repeated in large paragraphs. When writing your graduation thesis, you can learn from the content of your published small thesis, but you must quote and annotate it appropriately to show that you have considered the work of the small thesis instead of copying and pasting it directly.

The graduation thesis should contain more innovative contents and research results to show its academic value and contribution. If a large paragraph quotes the content of a small paper published by itself, it will be regarded as plagiarism, which will have a negative impact on the author's reputation and future academic development. Therefore, when writing graduation thesis, we should abide by the principles of academic integrity and intellectual property law, ensure that the content is our own original achievements, and make appropriate quotations and comments.
