What stages did China's calligraphy go through?

There are roughly three stages: first, from Oracle Bone Inscriptions in Shang Dynasty and inscriptions on bronze in Shang and Zhou Dynasties to Biography; Second, from seal script to official script; Third, from official script to regular script. Oracle Bone Inscriptions and Jin Wen became Xiao Zhuan, the former was closer to the realistic pictograph of the picture, while the latter's strokes turned round and regular, and gradually alienated from the shape of the object. Oracle Bone Inscriptions's knife marks are obvious, while the bronze inscriptions are thicker and the shape is more casual. Words with few strokes occupy small space and have small strokes. Each stroke occupies a grid. From Xiao Zhuan to Li Shu, it is the biggest change of font and the turning point from ancient Chinese characters to today's characters. The font structure of Xiao Zhuan is broken, the pictographic meaning is weak, and the symbolism is strengthened. From "Xiao Zhuan" to "Li Shu", there are generally changes in square folding and horizontal, left and right strokes. Xiao Zhuan became Li Shu, and the basic pattern of modern characters and strokes has been formed. From Li Shu to regular script, in addition to using. The font structure has remained basically unchanged. In addition, there are cursive and running scripts. Cursive writing is scrawled writing in various fonts. Now, cursive script refers to certain fonts, such as Cao Zhang and Crazy Grass. The font and brushwork of Mad Grass and Li Kai are very different. It is an art and has lost its communicative function. Running script is a font between regular script and cursive script, which is not as neat as regular script or cursive script.
