1. Open the paper with chapter number;

2. Format: Note that the titles at the same level here should be formatted in the same format; For convenience, create a new style for each level of title; For example, after setting the format of "Introduction", select the introduction, right-click, select "Save the selected content as a new quick style" in the style and name it "First-level title", then select other titles of the same level and set the format as "First-level title".

3. after setting the format, select "define new multilevel list";

4. In the pop-up dialog box, click the "More" option;

5. define the title of level 1;

when setting a level, we mainly pay attention to the following options: Level to be displayed in the library, Link Level to Style (here we choose the first-level title), Numbering Style of this level, and Format of Input Number. Note that in the format of input number, the required words or symbols can be inserted before and after the number. In this example, Chapter and Chapter are inserted.

6. define level 2;

generally, we will number level 2 as 1.1, so we should first select level 1 in "The included level number comes from", then select "This level number style", and add "."in the middle, and the number style "1.1" will appear in the figure. We will check "Regular form number" to get the "1.1" we want.

7. After setting up according to the previous steps, click OK, and you will find that the chapter titles of the paper have been automatically numbered according to the form we want.
