Formally speaking, calligraphy focuses on expression, followed by form and quality. It can also be said that wisdom has no limit and its laws are uncertain. Those who have the spirit of the wind come first, and those who have the lack of morality come second. Mystery is what the ancients said: "the mystery lies between books and ghosts, out of the appearance and deep reasons of things." From its point of view, calligraphy art can be said to be a silent and invisible stage.
Calligraphy art has its own rules, such as paying attention to writing, wrist movement, pen, ink, structure, composition (distribution), charm and so on. Its artistic form is often to express thoughts, feelings and ideals through art, and it can also be described as "pen feeling and ink interest".
Of course, although calligraphy contains some factors to express feelings, it must rely on some object-Chinese characters; For example, it tells stories and describes inner feelings like abstract literature, without the basic structure of Chinese characters and the essence of dotted lines, but it is similar to instrumental music. Instrumental music is composed of melody and harmony.
