In the history of China, official script rose among the people, and was officially recognized as an official font when it was mature. Therefore, official script is a kind of grass-roots calligraphy, which has a lot to do with its origin. This kind of official script font has changed part of the original seal script into a folk prescription, and gradually appeared the basic strokes of modern Chinese characters such as left stroke, press stroke and dot stroke. The unique "wave horizontal" writing method in official script increases the aesthetic feeling and rhythm of the font. By changing the seal script, complex strokes become more concise and more convenient for people to write and use. Due to these advantages, Lishu gradually penetrated into the people and appeared in inscriptions and engraved books.
In the middle and late Han Dynasty, Lishu began to spread from the folk to the official, and achieved official status, becoming the mainstream font in the Han Dynasty. The official script of Han Dynasty has a far-reaching influence on the development of fonts, which has been used in dynasties since Han Dynasty.
Official script has a great influence on the development of ancient and modern characters. Known as the watershed of China's ancient and modern characters. The characters produced before the official script are called ancient characters, and the characters produced after the official script are called modern characters, which are very similar to the Chinese characters we use now. Lishu is a popular calligraphy from the bottom up, which has developed from the initial folk calligraphy to the official calligraphy, and is the most basic calligraphy.
