Audience intersection is to generate a new audience from the existing audience through AND (intersection), OR (combination), and difference calculation.
If one or more audiences pass and, or, or are poor with other audiences to form a new group of people, they will also be classified as audience intersection. For example, an existing population is performed with a tag filter and the calculation generates a new audience.
Procedure
Choose Workspace> User Insight > Audience Insight > audience Filter to go to the audience Filter page.

Click Existing audience on the left side, or drag Existing audience from the left side to the right side. A audience Card is added to the right side.
Select an existing audience from the drop-down box.

Click Existing audiences in the left-side navigation pane to add a new audience card below the existing audience card. Alternatively, drag Existing audiences from the left side to the right side in the required order, as shown in the following figure.

In the new Select audience card, select an existing audience.

By default, the relationship between different groups is AND, which supports AND, OR, and DIFFERENT, as shown in the preceding figure. Click the text between cards to switch.
You can click the
