1. Double-click the mouse to enter the footer position of the summary page, and the header and footer toolbar will automatically come out. The "Link to Previous Page" option is yellow. Click it to cancel it and make it gray. Then select "Format Page Number" and set the start page at "Start Page Number" to 1, and the abstract will become the first page.

2. In the first column of Format Page Number, in the drop-down option of number format, instead of selecting number format-1-, you default to 1, 2,3, and then click-yourself, thus avoiding the change of the directory.

3. In the lower left corner of word, section break's full text is still a section, and the page break is to divide the full text into two sections. The latter changes the page settings of the document in the second section, horizontally and vertically, and the first section will not change accordingly. Personally, I don't think the page numbers will be rearranged whether I insert a page break or a section break. How is it set up here?
