Because the update summary of friends is turned on, it will be displayed in the dialog box. If this feature is not turned on, it will not be displayed in the conversation window. The specific steps to turn this function on or off are as follows:

1. First, open QQ on the computer, enter your account and password and log in.

2. After logging in successfully, select the three horizontal lines in the lower left corner of the QQ panel, and then click the "Settings" button in the pop-up pane.

3. Select "Conversation Window" in the left column, and check or cancel the box before "Show friends' updates in chat window" in the information display on the right (if checked, friends' updates will be displayed in the display window, otherwise they will not be displayed).
