Generally speaking, the graduation thesis is allowed to be repeated, but the repeated part cannot exceed a certain proportion, which may be different in each school. Our school is 20%, which means that the * * * part you quoted can't add up to more than one fifth of the full text. The part you completely copied, even if you indicate the source, is counted as a duplicate. If you quote this, you should write more in other places yourself, as long as the repetition rate of your final full text is lower than that stipulated by the school. Don't worry, it will usually pass.
