Suppose senior students want to check the duplicate in advance, they can go to the college library to test the duplicate. However, such opportunities are very limited, and it is not recommended to use the first draft, which is a waste. Fortunately, there are many third-party platforms that provide knowledge network testing and duplicate checking. However, senior students should learn to distinguish between true and false, so as to avoid the leakage of papers and affect their normal graduation. Here, I recommend paperred to check the repetition of Wang Zhi, and the result is the same as that of the school.
