The other party has set a comment on the detailed information of your friend (you) in the WeChat address book. The specific steps are as follows:

1. Click "Friend Nickname" to enter the details interface, and click "Set Notes and Labels" to enter the notes information interface;

2. Enter the name of the note under "Note Name", such as Zhang San;

3. Enter a label under the label, such as classmate, and save it;

4. Enter the phone number under "Phone Number";

5. Add a picture below the description. You can choose "Take a photo" or "Select from an album". After adding the picture, click "Finish" to return to the friend details interface.

After the setting is completed, the other party will display the phone number of your friend (you) in the "phone number column" below the friend details.
