I talked about how to quickly typeset titles, so let's talk about how to set up pages.

As shown in the figure below, we should set the page with a margin of 25mm at the top (ceiling) and left (opening), a margin of 20mm at the bottom (anchor point) and right (cutting), a binding line of 5mm and a header and footer of 5mm.

Click layout.

Select margins

Select a custom margin.

Set the margins, and then set the gutter.

Click the layout first, set the header and footer in turn, and click OK to finish.
