Do you check the copy of the paper on VIP? Did you check the program? There is nothing wrong with the writing. I only care about the procedure. The school uses the census, but I heard that the school has the last database, mine. Check the copy of the file on VIP. Not a program, but just text. If you only care about the program, you can only submit the program part for duplicate checking.

When the school census is repeated, a database of previous papers will be established, which will cover papers submitted by previous students. Therefore, if the school has the last database, it may detect that the paper is duplicate with the last student's paper. In order to avoid this situation, we can try to choose new research topics and directions, try to express them in our own language and ideas, and avoid being similar to other people's papers.
