Calligraphy introduction:

Official script, also called Han Li, is a common solemn font in Chinese characters. Its writing effect is slightly wide and flat, and the horizontal painting is long and the vertical painting is short, showing a rectangle, paying 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, which had a great influence on later calligraphy. Calligraphy is called "Tang Kai of Han Li".

Official script is also called "history book", "supplementary book", "eight-point book", "official book" and "sub-book". Among them, there was a post of "Shu Fu" in Han Dynasty, and he was a junior official who wrote full-time, hence the name "Shu Fu"; At that time, there was a saying of "eight points", which was called "Li" when the gesture was closed and there was no wave, and the gesture was called "eight points"; "History books" are named after people who are used to it. The main feature of official script is "wave picking" (or goose tail), so people have long called the style of wave method "official script".
