1: Open the QQ2009 login box, find the QQ number that needs to be hidden, click the cross behind the number → select "Delete all records of this account"? → ok. (Note: All chat records of this QQ will be deleted, please back them up first). If there is no QQ number information in the login box, please go directly to step 2.
2. Re-enter the QQ number to log in. (The first time you log in, a bound mobile phone window will pop up. Close it quickly so as not to delay time, and move the QQ main panel to one side so as not to block the setting window behind it. ).
Click on your QQ avatar at the top left of the QQ main panel → Modify the system settings at the bottom left of the data window → Chat with friends on the left → Remove the check in front of "Show business icon on the mini data card" → Apply at the bottom right → Confirm again.
3: Click System Settings on the lower left again → Check "Show business icon on mini data card" → Apply → Confirm again.
4. Speed Click "Small Hammer" above a row of QQ icons in the modify data window, and all QQ icons will appear in the pop-up window → Click to hide → OK at the lower right → OK. Operation completed.
If the first operation fails, you can delete the number data in the login box and hide it again, and the step will naturally succeed. ?
After the icon is hidden, the function is not affected, no matter what version of QQ your friends use, they can't see it.
Tip: Tencent has several new icons that can't be displayed or hidden in QQ2009, but you can hide them directly with the new version of QQ: log in to QQ, double-click your avatar at the top left of QQ panel → icon management on the right side of a row of icons in the window → click the new icon to be hidden in the box → OK → OK.
