System: IOS 15.4
Software version: WeChat 8.0.22
It can be seen that the WeChat circle of friends is not like QQ space. Although they are all apps owned by Tencent, some principles are still different. Under normal circumstances, the signatures of your circle of friends will not be displayed, only when they view your details, your circle of friends, or click on the photo album themselves.
How to view it: Open WeChat, go to the "Me" page and click on our avatar. You can see the personalized signature at the bottom of the personal information page. Click it to set it. Remember to click "Save" on the top right after setting. Then we return to the main interface of WeChat, click "Discover" and select "Friends Circle". Click on your avatar. Then you can see the personalized signature on the personal album page.
