Why is the screen name that appears when replying to others in QQ space different from my QQ screen name?

You click on the space to dress up, and then move the mouse to the big card in the space. Did "edit" appear? Then you click Edit, enter the name of the screen you want to change, and then press OK or Save. Anyway, it is "OK" or "Save" and then click "Save" in the upper right corner. The nickname in your space settings is your QQ name. Be sure! Hope to adopt, thank you!
