It is a sub-script evolved from the seal script.
Fenshu, also known as Bafenshu or Fenli, is a type of official script. Ancient books say: Cizhong's regular script was cramped, so he extended it into eight characters, hence the name Bafen. That is to say, Mr. Wang Cizhong (during the period of Qin Shihuang) believed that seal script had its limitations, so he took advantage of the situation and guided the separation of the writing style that moves to both sides like the character "eight", so it is called bafengshu, which is the predecessor of official script. The difference between official script and bafenshu is just like today's simplified Chinese characters and traditional Chinese characters.
Because of the characteristics of the eight-point script, the more vivid explanation in ancient times is to take the two-part seal script and the eight-part Li character (called Li before the Tang Dynasty) (which means auxiliary). It was a method of recording events created because of the inconvenience of writing in seal script. )) combined.
The emergence of the eight-point calligraphy:
Wang Cizhong was a famous calligrapher in the Qin Dynasty. At that time, people generally used Qin seal script with long fonts and very even strokes. However, this font was complicated and difficult to write. Not only was it inconvenient for ordinary people to use it, but officials and civil servants were also troubled by the mountains of official documents every day. Wang Cizhong, who loves reading, is no exception. He suffered from the difficulty of writing this kind of writing and deeply realized the necessity of reforming this kind of writing.
So, he tried to find a way to collect various bells, tripods, utensils and imperial edict texts, arrange them together according to the same characters but different shapes, compare them with each other, and polish them repeatedly. After a long period of hard study, his hard work paid off and he finally created a brand new "eight-point book".
