What font was used in Qianlong period?

During the Qianlong period, the fonts used were line, grass, kai, Li and seal.

Running script: It is a kind of calligraphy with both practical and aesthetic value, which became popular in Wei and Jin Dynasties. In order to facilitate writing, some strokes of regular script are broken into links, folded into songs, and even become less changeable, which becomes a running script.

Cursive script: produced because of the requirement of simplicity and quickness in writing. There are three kinds of cursive scripts: Cao Zhang, Jincao and Kuangcao, and the cursive script corresponding to regular script is Jincao.

Regular script: also known as regular script, original script and official script. It gradually evolved from official script, becoming more simplified and more horizontal and vertical. Ci Hai is interpreted as "square, straight and exemplary". This Chinese character font is correct, which is the popular handwritten orthographic Chinese character.

Official script: The writing of Xiao Zhuan is very simple. The standard font used in the Qin Dynasty was Xiao Zhuan. It was not until the middle of the Western Han Dynasty that Li Qin was replaced by a simpler and easier font, which is still a kind of calligraphy. It is characterized by straight strokes and extended strokes.

Seal script: seal script can be divided into big seal script and small seal script. The broad sense of Da Zhuan is all the characters in the pre-Qin period, including Oracle Bone Inscriptions, bronze inscriptions, bronze inscriptions, and other characters prevailing in the Spring and Autumn Period and the Warring States Period. Small seal script is a font formed after Qin Shihuang unified the six countries and completed the big seal script.
