Lishu is a Chinese font, including Qin Lishu and Han Li. It is generally believed that it is developed from seal script, with wide and flat font, long horizontal painting and short vertical painting, and pays attention to "swallow tail of silkworm head" and "twists and turns". According to the unearthed bamboo slips, official script originated in Qin Dynasty, and Cheng Miao was also called official script. Han Li reached its peak in the Eastern Han Dynasty, inherited the tradition of seal script, and opened the Wei, Jin, Southern and Northern Dynasties, which had a great influence on later calligraphy. The calligraphy circle is known as "Tang Kai of Han Li".
Regarding the definition of official script, Mr. Wu said in the article "Looking at the Early Official Script of Qin and Han Dynasties from the Unearthed Silk Slips of Qin Bamboo Slips": "It can be explained by the original meaning of this word. Shuo Wen Jie Zi explains that Li means "attached", while The Biography of Feng Yi in the Later Han Dynasty teaches it as "subordinate", which is still in use today, and there is the word "subordinate" in modern Chinese. The Book of Jin, Wei Hengzhuan, Shuowen Jiezi Preface and paragraph notes all think that official script is inferior to Sasuke Zhuan, so official script is an auxiliary font of Zhuan Zhuan. "
Secondly, what is ceremony? What is the strict difference between ceremony and seal script? Mr. Wu has done some analysis in the above article, and here are some small paragraphs worth considering. Wu Yun: "Xiao Zhuan still retains the meaning of hieroglyphics to draw its finished products in a body;" Lishu went a step further, breaking the knot of pictographs with stroke symbols and becoming pictographs without pictographs "(see the original text, for example).
He added, "seal script and official script are actually two systems, marking two main stages of the development of Chinese characters. Xiao Zhuan is the end of ancient pictographic characters, and Lishu is the beginning of new writing that turns pictographic characters into strokes. " "When we judge whether a font is an official script, we must first see whether it destroys the structure of the seal script and loses the original intention of the pictograph."
