Short message communication

Common ground: they are all communicating.

Difference: Face-to-face communication is more real and sincere, but after a long time, there will be more contradictions.

SMS communication is a waste of money, and there is nothing to say.

Chatting on QQ is just a waste of time. Instead of chatting on QQ, go out to bask in the sun. Of course, if two people live apart, chatting on QQ can also promote feelings.
