The development order of calligraphy fonts is as follows

1, Oracle Bone Inscriptions: It is called "Wen Qi", "Oracle Bone Inscriptions", Yin Ruins or "tortoise shell and animal bones". The oldest existing mature script in China.

2. Bronze inscription: refers to the inscription cast on the bronze wares of Yin and Zhou Dynasties, also known as Zhong Dingwen.

3. Xiao Zhuan: After Qin Shihuang unified China, he implemented the policy of "words with the same language, cars with the same track", and the policy of unified measurement was under the responsibility of Prime Minister Li Si. On the basis of the big seal script originally used in Qin State, he simplified it, canceled six other characters and created a unified writing form of Chinese characters.

4. Official script: Qin Li, Han Li, etc. Generally speaking, it is developed from seal script, with wide and flat font, long horizontal painting and short vertical painting, and pays attention to "silkworm head and goose tail" and "twists and turns"

5. Regular script: also known as regular script, real script and official script. It gradually evolved from official script, becoming more simplified and more horizontal and vertical.

6. Running scripts: divided into running scripts and running scripts. A font between regular script and cursive script is produced, which makes up for the defects of slow writing speed of regular script and illegible cursive script.

7. The cursive script has simple structure and continuous strokes. Cao Zhang is divided into grass and grass, and grass is divided into weeds and grass, which makes me feel beautiful in madness.
