First log in to QQ with your account number and password, and then wait until the main QQ interface pops up, as shown in the figure.
Then we click "System Settings" next to the main menu in the lower left corner, as shown below.
Then the dialog box of system settings will pop up, including three different types of settings: basic settings, security settings and permission settings.
Then, we have to switch to "Permission Settings", and then under this option, we can see that there is an "information reminder" option on the left, and we click it.
Above the information reminder on the right, we can see that one item is "Display Tencent Mini Edition after logging in", which is the chief culprit harassing us every day. We can remove the checkmark from the system default box.
