Check the duplicate checking requirements of the school. If the school requires to check the contents of important references, then students should also include references in the duplicate check to ensure that the duplicate check results are consistent. If the school requires only the text to be tested, then the students will delete the others themselves.
Part, leaving only the body part for testing. Marking the references in red does not mean that the references are reused, but that the submitted papers are not standardized and accurate.
