5. Go to the management group page and select Manage group members at the top.
6. In the upper-right corner of the management group members, click the three-line icon and select Delete group members from the pop-up menu.
7. Now there is a "-" next to the success of the deletion. Click it.
8. At this time, it will tell you if you want to delete it successfully.
9. Another option to delete is that the user cannot join the group after deletion. We can select this option to avoid further advertisement.
Reminder
T people in the QQ group need to have management permissions. If they don't, they won't be able to do it. Of course, the same is true for T people in the computer, so there is no need to repeat T twice. Sometimes T will show that this member is still in the group. This may be due to network latency. We just need to wait for a while.
