If you have two numbers, you can copy them. The method is as follows: If you want to copy Zhang San's name, add Zhang San to a number as a temporary friend-send Zhang San's name directly to the dialog box of another number (just drag Zhang San's name into the dialog box with the mouse to send it)-the name is received in the dialog box of another number, and the color turns blue after clicking the mouse twice. I hope you didn't do anything wrong. . Have fun!
