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

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

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

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

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

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

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

Step 8: On the interface, you can see the latest signature, thus completing the change.
