The status displayed by qq Stealth will be: not online. After QQ is invisible, the avatar will be in a gray state, and friends don't know if you are online. But the other party can send the message normally, and you can also receive it. The difference between QQ stealth and offline or busy status is that if you set automatic reply, when the other party sends a message, the other party will receive your automatic reply message, but stealth will not.
