Symbol is a conventional concept used to refer to a symbol of an object and a medium for conveying information.
Every symbol has its foundation for birth, which is the relevant contextual context.
At the same time, due to different social and cultural values, people may have some deviations when accepting and interpreting symbols.
But it can be certain that the symbolic images and information conveyed by people are universal to a certain extent, which can reduce some communication barriers in design and expression.
