Oracle Bone Inscriptions: It is well documented that in the late Shang Dynasty, about14th century BC, the initial stereotyped writing, namely Oracle Bone Inscriptions, was formed.
Da Zhuan: Late Western Zhou Dynasty-Qin Dynasty
Xiao Zhuan and Li Shu: Li Si, the prime minister of Qin Dynasty, simplified Da Zhuan and changed it to Xiao Zhuan. However, Xiao Zhuan also has its own fundamental shortcoming, that is, its lines are very inconvenient to write with a pen, so almost at the same time, a kind of official script with flat sides was produced.
Running script: It appears almost at the same time as the eight-part essay, and its form is very close to the eight-part essay and the later official script. This is equivalent to changing (chapter) cursive script from official script to other branches derived from "regular script". In addition to official script, the "regular script" in Huanling period was followed by "eight-part essay", so people think that running script is another branch of "eight-part essay". In fact, it is the same as other calligraphy styles. It was originally founded as a general mass writer. As long as it is written in other calligraphy, it becomes a running script without official style. It can be seen everywhere in bamboo slips unearthed at the end of Han Dynasty. At the end of Han dynasty, running script was not widely used. It was not until the appearance of Wang Xizhi in Jin Dynasty that it became popular.
Regular script: Regular script (also known as authentic script) combines official script and cursive script, which became popular in the Tang Dynasty.
Cursive script: Official script has developed to a mature stage, and the readability and writing speed of Chinese characters have been greatly improved. After Li Shu, it evolved into Cao Zhang, and now it is grass. In the Tang dynasty, there was Weeds, which expressed the writer's thoughts and feelings with a pen.
Song Dynasty: With the development of printing, block printing has been widely used, and Chinese characters have been further improved and developed, resulting in a new writing method-Songti printing font. After the invention of printing, the carving knife used for lettering had a far-reaching influence on the glyph of Chinese characters, resulting in a kind of printing font with fine horizontal and thick vertical, which was eye-catching and easy to read, and was later called Song Style.
Like seal script, official script, regular script, running script and cursive script, they were basically used from Qin Dynasty to Han Dynasty. Chinese characters are a gradual process. It is impossible to be accurate to several years, let alone write for several years.
