Generally speaking, it's okay. Undergraduate thesis will not be searched by academic misconduct websites. To tell the truth, more than 80% of China's bachelor's thesis is seriously plagiarized, and the problem of master's thesis is also very serious. Can you pass the defense or see the school? Better schools will be stricter. It shouldn't be too much plagiarism. You can make more articles, change topics and keywords, and delete chapters ~ ~

The above is for reference only, hehe.
