I contacted his qq number. Can I receive messages from others? Can she see the news from others?

I can't accept it, but there is a message on the current qq number telling you that another qq number has come up. You can directly switch to another qq number to view information.

Open QQ login, click on your avatar in the upper left corner of the message chat interface to enter some settings of your QQ.

After entering, there is a "Settings" in the lower left corner of the interface, then click to enter "Account Management", find "Associated QQ" in the interface after completion, and then click to enter.

Click the "Verify Now" button after entering, and you can see the QQ number and "Add Account" that have been added now. For example, if we select an existing account, click Select.

After completion, the system will automatically return to the original message chat interface, and you can see that two QQ numbers have been associated.
