1. First, open a WPS document for demonstration. We need to modify the title. Just double-click the header with the mouse to enter the editing state, as shown in the figure, and enter the desired text content in the header.

2. We can also click "Insert" and select the "Header and Footer" button in the toolbar to modify it, which has the same effect as double-clicking the header or footer.

3. Sometimes we need to set different parity pages. Just click the "Header and Footer Options" button to bring up the option box. You can set different parity pages and different home pages, which are common functions.
