Introduction to seal script:
Seal script is one of the ancient Chinese characters, also called seal script. It is a general term for ancient Chinese characters. "Seal makers spread it, spread its physics, and apply it endlessly." The ancients thought that seal script was written by Cang Xie, but this is not credible. The generation of a kind of writing needs a long development process, and it is impossible for a person to complete it in a short time. Generally speaking, seal script includes all the characters before official script and their extended genera, such as Oracle Bone Inscriptions, Jinwen, Shi Guwen, the ancient prose of the Six Kingdoms, Xiao seal, Miao seal, overprint and so on. Narrow sense mainly refers to "Da Zhuan" and "Xiao Zhuan". The font of seal script is round and the structure conforms to the meaning of six books, so Sun said in the Tang Dynasty, "Seal script is graceful and smooth".
Dazhuan refers to Oracle Bone Inscriptions, Jinwen, Jinwen and Six Kingdoms, and retains the obvious features of ancient hieroglyphics.
Xiao Zhuan, also known as "Qin Zhuan", is a commonly used character in Qin State and a simplified font of Da Zhuan, which is characterized by uniform and neat glyphs and is easier to write than Wen Shu. In the development history of Chinese characters, it is the transition between seal script and official script.
