There are two schemes, one is to use hanging indent for paragraphs with special format, and the other is to use automatic numbering (although this is not mentioned in the title, it is recommended by Microsoft).

Taking the Word program in Office365 as an example, the steps of the two schemes are described in detail below:

Option 1: hanging indent

As shown below, enter the paragraph interface, select the special format in the paragraph, and select hanging indent 2ch (generally 2, Chinese single space spacing). In hanging indent, due to the different character spacing between a single Chinese character and English letters, there will be a slight deviation in the alignment of Chinese and English paragraphs.

Scheme 2: Automatic numbering

(1) As shown in the figure, in the Paragraph Options area, click Create Custom Numbering Style.

(2) As shown in the figure, select "1, 2,3,4 ..." For the number style, add the bracket "[]" and confirm.

(3) Click to insert the number of the newly created custom style, select the number, and select it with the right mouse button to customize the starting number.

(4) Customize the corresponding number and confirm it.

The following is a comparison between hanging indent and automatic numbering:
