Its writing effect is slightly wide and flat, and its horizontal painting is long and straight and short, showing a rectangular shape, and it pays attention to "silkworm head and goose tail" and "twists and turns". Lishu originated in the Qin Dynasty and was compiled by Cheng Miao. It reached its peak in the Eastern Han Dynasty, and had a great influence on later calligraphy. The calligraphy circle was called "han li Tang Kai".
