Say happy birthday to the person you like, which is better, sending text messages or buttons, online, etc.

It's best to say it in person, then make a phone call, then send a text message, and the last time is to send qq. I don't know if you are a girl or a boy. Anyway, if you like a girl, you'd better not use QQ for important things, which will give girls a feeling of little attention. As for what boys think, I don't know. It is entirely personal feelings and opinions, for reference only.
