How can I change my default comments when others add them?

1. Open the chat software and find the option of "Contacts" or "Friends" in the main interface.

2. In the list of contacts or friends, find the friend whose comments need to be modified, and click on his avatar to enter the friend profile page.

3. On the friend profile page, find a button similar to "Edit Notes" and click to enter the note editing page.

4. On the comment editing page, you can modify the friend's comments, including deleting the original comments and adding new ones. Click the "Save" or "OK" button after finishing the modification.
