There are several categories of calligraphy.

The development of China's calligraphy in China has gone through a long process, from the earliest stone carvings, bamboo slips to brush calligraphy, and gradually formed a variety of calligraphy styles. Its classification can be divided into four bodies, six bodies and ten bodies. Its classification is as follows:

(a) "four books" classification:

(1) seal script;

(2) official script;

(3) cursive script;

(4) true books.

(2) Classification of Six Books:

(1) seal script;

(2) official script;

(3) Cao Zhang;

(4) Official script (also known as "true script" or "regular script");

(5) running script;

(6) cursive script;

(3) the classification of "ten-style book":

(1) Ancient prose-written by Cang Xie during the Yellow Emperor.

(2) the seal script-Zhou Xuanwang Taishi Shicheng.

(3) written by Wen Shu-Shi Shu.

(4) Xiao Chuan-Qin Shihuang inherited Li Si.

(5) Eight points-written by Qin Shanggu and Wang Cizhong.

(6) Official script-written by Cheng Miao, an inferior in Qin Dynasty, also called "Official script".

(7) Cao Zhang-Han Huangmen Li You's family.

(8) Running script-written by Liu Fasheng in Yingchuan at the end of Han Dynasty.

(9) Bai Fei-Cai Yong, the left viceroy of the later Han Dynasty.

(10) cursive script-written by Zhang Zhi in the later Han Dynasty.

The names of "ten-style calligraphy" are ancient prose, big seal script, eight-part essay, official script, Cao Zhang, running script, flying white and cursive script. There is no such thing as regular script, because at that time, in people's minds, official script was regular script (that is, "original").
