2. After Qin Shihuang unified China (22 1 year ago), Xiao Zhuan implemented the policy of "learning from books, learning from cars". Unified measurement's policies are in the charge of Prime Minister Reese. On the basis of the original seal script used by Qin, Xiao Zhuan simplified it, canceled six other characters and created a unified Chinese writing form. It was popular in China until the end of the Western Han Dynasty (about 8 AD) and was gradually replaced by official script. But because of its beautiful font, it has always been favored by calligraphers. Because of its complex strokes and simple form, it is possible to add twists and turns and seal cutting at will, especially the official seal that needs anti-counterfeiting. Seal script was always used until the collapse of feudal dynasty and the emergence of modern new anti-counterfeiting technology.
? During the Spring and Autumn Period and the Warring States Period, Chinese characters in different countries were different in simplicity and complexity. After Qin Shihuang destroyed the Six Kingdoms, he ordered the Qin Dynasty's Biography as the standard to unify the national characters. Seal script, also known as "seal script", is a combination of small seal script and big seal script. Because it is customary to call seal script "big seal script", later generations often refer to it exclusively.
? Chinese characters developed to the stage of Xiao seal script, and gradually began to shape (outline, strokes, structure). The pictographic meaning is weakened, which makes the characters more symbolic and reduces the confusion and difficulty in writing and reading. This is also the product of the first large-scale use of administrative means to standardize writing in the history of China. The Qin Dynasty unified the national characters with the sorted seal script, which not only basically eliminated the phenomenon of different lines of characters in different places, but also greatly changed the situation of different fonts in ancient Chinese, and played an important role in the development history of China characters.
