We don't change the head image of WeChat, the background image of friends circle and the signature of WeChat personality, so we are committed to boys. Boys have misunderstood the girls they like before. Boys have never changed the WeChat avatar before, nor have they changed their friends' background pictures, nor have they written WeChat personalized signatures. The boy misunderstood the girl he liked and unconsciously deleted the girl's WeChat on impulse. Now all the boys have written their own WeChat avatars, friends' pictures and personalized signatures to this girl.

All of the above are good online platforms and a step to express people's thoughts now. Without direct expression, the actual opportunity may not have arrived yet.

Personalized signature: because each netizen writes different words, including aphorisms, proverbs, teasing sentences and so on. Pictures and animations are also very useful as signatures, full of personality and different styles, so they are called "personalized signatures". Signature is a visual symbol representing personal information and personal aesthetic taste in all relationships such as society, law and contract. Also called signature and signature.
