China's writing develops the writing of writing to an aesthetic stage-it combines the creator's ideas, thinking and spirit, and can stimulate the aesthetic feeling of the aesthetic object (that is, the formation of a real sense of calligraphy). Records can be traced from the end of Han Dynasty to 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 characters and the appearance of early works with artistic characteristics have their particularity and times. As far as calligraphy is concerned, although there were pictographic characters-Oracle Bone Inscriptions in the early characters, the complexity and simplicity of the same character were different, and the strokes were also different. However, there is a law of symmetrical balance, and there are also some regular factors such as pen (knife), word knot and composition. Moreover, in the organization of lines, the beginning and end of strokes change, showing the meaning of calligraphy and strokes. Therefore, it can be said that the emergence and existence of the previous generation of 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.
China's historical civilization is a diachronic and linear process, and China's calligraphy art shows its development under such a background. The appearance of Wang Xizhi, a great calligrapher, made the art of calligraphy shine brilliantly, and his artistic achievements were highly respected in the Tang Dynasty. At the same time, a number of calligraphers appeared in the Tang Dynasty, such as Yu Shinan, Ou Yangxun, Jun Yiliang, Yan Zhenqing and Liu Gongquan. In calligraphy attainments, each has his own merits and diverse styles.
