For the girl who is about to go to college, we should first find a suitable platform and then give her a good first impression. We should choose a good-looking selfie as our avatar. This beauty does not necessarily represent the face value, but it should give people a feeling of being friendly to the sun as a whole. Don't be greasy or obscene, or do some strange actions, and don't choose a messy background. You can find a place with good environment and good pipes to take selfies outdoors, and the effect will be good.
The second is how to chat, which is really important. I think as long as you don't do it yourself, you can talk to girls, and you don't need many skills, respect each other, find some interesting topics, or just talk about the little things in life.
