On social media, personalized signature is a way to express yourself, which can reflect a person's personality characteristics and emotional state. Some people choose to express silence in their signatures, perhaps because they want some time alone, or because they want their friends to know that they don't want to talk now. Of course, some people will also express their dissatisfaction or protest about something in their personal signatures. In this case, silence is a silent way of protest.
In a word, the meaning of silence in Tik Tok's signature is varied, which should be understood according to the individual's actual situation and expression intention.
