Identify the types and effects of errors: First, you need to carefully check the types of errors and their possible effects. For some small mistakes, such as spelling mistakes, you can correct them yourself. However, some important errors, such as data errors or analysis problems, need to be handled more carefully.

Contact the tutor or tutor group: If you find any important mistakes in your doctoral thesis, you should contact the tutor or tutor group immediately. Explain the wrong situation to them and ask for their advice and help. If possible, it can be revised and improved under the guidance of the tutor.

Submit a statement of revision or correction: If the mistake is serious, it is necessary to submit a statement of revision or correction to the school or relevant academic institutions. This usually needs to follow the specific procedures and requirements of the school or institution. Before submitting the amendment or correction statement, you must carefully check and ensure that all information is accurate.

Apologize publicly and correct it: If the mistake affects academic opinions or research progress, or brings adverse effects to relevant personnel, it may be necessary to apologize publicly and correct it. This may require submitting revised or corrected papers to relevant academic journals or conferences, or publishing statements on relevant websites or social media platforms.
