Ten years' immobility: Some people's QQ signatures can remain unchanged for ten years, and some people are tired of it, but he seems completely unaware of it. The most terrible thing is that his signature is not a philosophical phrase with profound meaning at all. For example, some people use "There is a Xiaohua Mall in front" as their signature, and they will do it for several years without thinking about changing it. Personality analysis: a typical person without vision will only focus on the focus of sight and will not notice everything in the corner. If he is a taxi driver, all he cares about is whether the steering wheel is sensitive enough, and he will never notice that a piece of paint has fallen off the roof!
