Hello! As far as I know, Tencent's QQ doesn't have this function. Now personalized signature updates on friends' QQ (when released) will be displayed in your QQ space in the form of "talk". In the QQ space, there is an item "Add Special Attention" in the upper corner of the Personal Center. You regard the friends or people you want to pay attention to as special attention, so whenever you log in to your QQ space or QQ, there will be a prompt in the space on the QQ panel, and you can directly see the newly released content of your friends by clicking into the space.

Click on the "Personal Center" → "Personal Center" page in the upper right of QQ space. There are two small buttons just below the "Publish" button in the upper right of the input box. The second button (round gear) is "Dynamic Settings" button → "Focus on Dynamics "→ Select the update information that needs attention in the friend space below, and check" Chat "→" Confirm "in the lower right.
