The duplicate checking system will check all the information in the paper. If users put references in the papers to be tested, they will also check the references, otherwise they will not check them. However, whether it is necessary to put references in the paper for testing requires students to check the duplicate requirements of the school. If the school requires to check the contents of important references, students should also check the references to ensure that the results are consistent. If the school requires only the text to be tested, the students themselves will delete other parts and leave only the text to be tested.

Marking the references in red does not mean that the references are reused, but that the submitted papers are not standardized and accurate. The main problem is that the format of the referenced related documents is not in the correct format. Incorrect format will make the reference related documents that do not need to participate in duplicate checking be wrongly identified, and even participate in duplicate checking together with the text. Therefore, we must use the writing format of references in a standardized way.

The references of the paper will not be included in the scope of duplicate checking, but if the format of our references is wrong, the references will be marked in red, so we should pay attention to the format of the references when writing the paper and avoid marking the references in red.
