I want to make a calligraphy book with wps. How to adjust the grid spacing?

First of all, I'm not sure whether you mean the number 8 or the pound. Generally, the text of normal textbooks adopts font No.5 (1 1.5pt), and the line spacing is generally 1/2 lines, and the word spacing is the default of each typesetting software. Newspapers use the font of Song Ti No.6 (8pt), and the line spacing is also 1/3. Generally, the word spacing is acceptable by default for all typesetting software.
