1. Select the first line (the one with a name is the best), use the left mouse button to select the inverted triangle of the style tool on the leftmost side of the format toolbar, select "Title 1", and then use the format tool to adjust the format of this line to make it almost the same as the previous format. Select the first line, double-click the format brush with the left mouse button, and brush out the 3, 5, 7, 9 … to be separated in the first line in turn. (If this line was originally titled 1, this step is unnecessary. )

2. Select Outline from the View menu to switch to the outline view;

3. Click the inverted triangle of the display level in the outline toolbar with the left mouse button and select "Display Level1";

4. "Ctrl+A" selects all articles;

5. Click the penultimate "Create Subdocument" button in the outline toolbar with the left mouse button;

6. Save the document to the location to be saved. (It's best to create a resume folder and save it in it)

7. Open the saved file location to find the separated document. This document is a subdocument and can be edited independently. You can also see the entire document in the master document without separation. (This belongs to the function of creating subdocuments, so I won't go into details. )
