As follows:

1. Seal script: There are two kinds of seal script: Da seal script and Xiao seal script. Dazhuan is divided into Oracle Bone Inscriptions, Zhong Dingwen and Shi Guwen.

Oracle Bone Inscriptions is the earliest writing, which was carved on tortoise bones and animal bones during the Yin and Shang Dynasties (3, years ago), when ancestors predicted bad luck, recorded divination, sacrifice and other activities.

Zhong Dingwen was an inscription carved on bronzes in Shang and Zhou Dynasties, also known as bronze inscriptions. The bell stands for musical instruments and the tripod stands for ritual vessels. In Zhou Xuanwang, there was a Taishi surnamed Shu who sorted out the words at that time. Shu Wen refers to Zhong Dingwen, a real seal script.

Shi Guwen was carved stone by Qin in the Warring States Period. Ten stone drums, shaped like drums, are now in the Palace Museum in Beijing.

Xiao Zhuan refers to the early characters in the initial stage, especially in Oracle Bone Inscriptions, which is not standardized. There are many ways to write a word, and there are many pictographic elements in the word, such as the word "horse".

2. cursive script: a font produced for convenient writing. It began in the early Han Dynasty. At that time, it was "Caoli", that is, scribbled official script, which gradually developed and formed a kind of "Zhangcao" with artistic value. Before the Han Dynasty, Zhang Zhi changed "Zhangcao" into "Modern Grass", and the style of characters was formed in one stroke. In the Tang Dynasty, Zhang Xu and Huai Su developed into "wild grass" with continuous brushstrokes and varied glyphs.

cursive script is characterized by simple structure and continuous strokes. "Big Grass" and "Little Grass" are symmetrical. Big Grass is purely grass-based, which is difficult to identify. Zhang Xu and Huai Su are good at it, and their words are formed in one stroke, occasionally disconnected, but their veins are constant.

cursive script can be divided into zhangcao, jincao and kuangcao.

Introduction

The cursive script is a script earlier than the regular script. Zhangcao began in the process of the evolution from seal script to official script, and official script has a greater influence on Zhangcao. The font is in the form of official script, and the characters are different and do not correct each other. Therefore, Zhang Cao is also called a cursive official script. The representative figures of Zhang Cao: Shi You, Du Du, Cui Yuan, Zhang Zhi, Zhang Xu, and others in the Han Dynasty, and Huang Xiang, Suo Jing and others in the Three Kingdoms.
