Click Group Settings, click Modify your group business card, and you can modify your own remarks in the remarks column. If you are an administrator and need to modify other people's comments, find the member you need to modify from the group member list on the right side of the group, right-click, click Modify or view the group business card, and modify it in the comments column. (The premise is that this member has not set up a setting that does not allow the administrator to modify his or her group name card)
