1. Re-edit the cover: re-edit the cover, delete or change the page number, and then re-print and bind the paper. If time permits, this may be the best solution.
2. Manually modify the page number: If the paper has been printed and the page number is wrong, you can manually modify the page number. You can manually modify the page number of each page by using a pencil or a PDF editing tool on your laptop. Please be careful not to change anything else when modifying the page number.
