1. you can click the mouse at the end of the text in the upper part of the blank page, start with the text in the lower part of the Automatic Blank Page, hold down shift, click the mouse, select the blank page, and then delete (solved my problem)
2. If there are few blank pages caused by PAGE breaks inserted, delete the page breaks and press the return key at the top of the blank page. (The pagination character is displayed when the editing mark is enabled in a common view)
3. If there are many paging characters, you can edit/replace/advanced/special characters/manual paging characters/replace all.
4. if you have drawn a table that occupies the entire page, the last carriage return cannot be deleted on the second page. You can narrow down the table or set the margins above or below to a smaller value, change the upper and lower numbers to a smaller value in the file/page settings.
5. Place the cursor at the end of the previous page and delete it with Del Jian. If the blank area is the last page and the mouse is on the first line, select "format"-"paragraph" and set the line spacing to a fixed value of 1 lb, the blank page will automatically disappear.
