1. First find the software shortcut, click to open the software, and then click the "I" icon in the lower right corner to enter the personal center. Then click on the avatar directly and enter "Personal Information".

Now you can see the "Personal Signature" menu in the last line of your personal information. You have not set your personal signature. Click "Open" to make settings.

3. Enter your personal signature. Be careful not to be too long here. There is a word limit. When finished, click "Save". Now, when you return to your personal information, you can find that you have successfully set your personal signature. Now, when you return to your circle of friends, you will find that your personal signature will be displayed under your avatar.
