Step 1: Find the WeChat icon on the phone desktop and open WeChat.

Step 2: After entering WeChat, click "Me" in the lower right corner.

Step 3: After entering the My interface, click on your avatar.

Step 4: On this interface, you need to click "More".

Step 5: On the more pages, you can see the personalized signature, and then click on the personalized signature.

Step 6: On this interface, delete the old signature and enter the new signature.

Step 7: After editing the text, click "Done" in the upper right corner.

Step 8: On the interface, you can see the latest signature, and the change is completed.
