What's the difference between personalized signature on QQ and talking about it? How do you feel today? Is it better to write it in your signature or talk about it?

Personality signature is like a label, indicating what kind of person you are, your personality, hobbies, or a deep understanding of life, outlook on life, values, love and other general things. And talking about meaning means talking about it, which is very casual. It can be a joke, an event, a mood, or other impromptu things. It is better to write a temporary feeling, a temporary mood. In fact, there are no clear rules. You can play whatever you want.
