Due to the unique characteristics of calligraphy, people can see that it is the unity of concreteness and abstraction. Calligraphy is permeated with the writer's strong emotions, so calligraphy is by no means a simple reflection of the objective, and calligraphy does have the function of expressing meaning, so it cannot be regarded as just expressing emotions. The text symbols expressed in calligraphy have a certain degree of abstraction. In addition, calligraphy must be processed and evolved based on the general text structure. Its abstract meaning is obvious. However, the semantics expressed in calligraphy do correspond to objective things, and it does make sense to say that it has concrete characteristics.
