Girlfriend loves to play mobile phone. How am I supposed to talk to her?

If you send a message, you can say dear. If you make a phone call, you can say something like Bao Er. Ask her if she is tired from studying, what she is doing, what food she has eaten, whether she has eaten too much, and whether the weather is cold or not. Tell her to take care of herself and not to catch a cold. When you go to see her, you can buy more food. She likes it. . . .
