You need to insert different headers and footers before and after, and insert-separator-section break-Next Page-OK, which makes the document form a "section". The concept of this section is very important, which is different from "page". Note that there are two pages and two sections at the bottom of the page, which means that the cursor is in the second section of page 2 and * * * on page 3.

Place the cursor and view-header and footer on the page (section) where different headers and footers need to be inserted, thus bringing up the header and footer toolbar. Note: There is a "Link to Previous" item on the toolbar. If you want the same header as the previous section, click here, and "Same as the previous section" will appear in the upper right corner of the page. If it is different from the previous section, there is no such hint. Click "Link to Previous" to convert!
