China's writing originated very early, which developed the writing of writing into an aesthetic stage-it integrated the creator's ideas, thinking and spirit, and stimulated the aesthetic feelings of aesthetic objects (that is, the formation of a real sense of calligraphy). The record can be tested between the late Han Dynasty and Wei and Jin Dynasties (about the second half of the 2nd century to the 4th century). However, this is not to ignore, dilute or even deny the artistic value and historical position of the previous calligraphy art form. The origin of China's writing and the emergence of early works with artistic features all have their own particularity and times. As far as calligraphy is concerned, although there are pictographs in the early script-Oracle Bone Inscriptions, the complexity of the same character is different and the strokes are different. However, it has the law of symmetry and balance, as well as some regular factors of using pen (knife), knot words and composition. Moreover, in the organization of lines, the beginning and ending changes of strokes have taken on the meaning of calligraphy and the meaning of strokes. Therefore, it can be said that the emergence and existence of previous calligraphy art not only belongs to the category of calligraphy history, but also is an important example for future generations to learn from and think about in the development and evolution of art forms.
