The origin of official script
Official script is also called "official character" and "ancient book". It is a font produced on the basis of seal script to meet the needs of convenient writing.

It originated in the Qin Dynasty and reached its peak in the Eastern Han Dynasty. Calligraphy is known as "Han Li Tang Kai".
