In the lower right corner of the computer, there is a place where your QQ is displayed (that is, the beginning (the place where it is turned off) and the other side (the right side) in the lower left corner of the computer), and your QQ logo (a penguin) will appear. When you click it with the left key, a box will appear, which says: Away, Online, Busy, Invisible and Offline. You will click on the last item of these items, that is, personal settings, and then you will click. Then there will be personal information. Then you can type what you want in the QQ personalized signature box. After typing, there are two options at the bottom of the box: OK and Cancel, and then you can click OK. Then there is a box that says: The server has accepted your information, and then click OK.
