What are the two mainstream writing fonts in Han Dynasty?

The mainstream writing fonts in Han Dynasty are Lishu and Cao Zhang.

Lishu, also called Han Li, is a solemn font commonly used in Chinese characters. Its writing effect is slightly wide and flat, the horizontal painting is long and straight, and it is rectangular, paying attention to "silkworm head and goose tail" and "twists and turns". Lishu originated in the Qin Dynasty, formed by Cheng Miao, and reached its peak in the Eastern Han Dynasty. Calligraphy is known as "Han Li Tang Kai".

Cao Zhang is one of the traditional calligraphy styles. It is an early cursive script, which began in Han Dynasty and evolved from cursive script to official script. Cao Zhang was roughly formed in the first year of Xuanyuan in the Western Han Dynasty and flourished in the Eastern Han Dynasty, the Three Kingdoms and the Western Jin Dynasty. It has become a mature and perfect calligraphy style, representing the face of cursive art from the Western Han Dynasty to the Eastern Jin Dynasty for more than 400 years.
