After Qin unified China, the "book with the same text" was implemented, and Qin Shihuang ordered the national standard font to be

After the Qin Dynasty unified China, it took a series of measures to consolidate its rule, including the famous Tongwen Lu, which unified the different writing styles used by various countries in the Warring States period into what was later called Xiao Zhuan.

Before the Qin dynasty unified the six countries, the vassal States acted in their own ways, and the writing forms were extremely disordered. This has caused serious obstacles to the implementation of government decrees and cultural exchanges. Therefore, after the unification of the six countries, Qin Shihuang took the unification of writing as a top priority, and ordered Prime Minister Reese, secretariat Zhao Gao and official minister Hu Wujing to sort out the writing.

On the basis of Qin script and referring to six scripts, Li Si created a new script with unified form and concise strokes, called "Qin Zhuan", also known as "Xiao Zhuan", as the official standard script, and abolished other variants.

Official script is also called "official character" and "ancient book". It is a font produced on the basis of seal script to meet the needs of convenient writing. The seal script is simplified, and the uniform circle lines of the seal script are changed into straight strokes, which is convenient for writing.

These two forms of writing are popularized all over the country. However, seal script is regarded as the standard script of Qin State, and the official documents of the emperor and the government are generally written in seal script, while unofficial documents are copied in official script.

Characteristics of extended data sealing scripts

1, the small seal script is rectangular, with one and a half words in the square script as the degree, one word is straight and the other half words are vertical feet, and the approximate ratio is about 3:2.

2. Xiao Zhuan is a stroke with horizontal and vertical strokes, round and even, and basically the same thickness. All horizontal and vertical paintings are equidistant and parallel, and all strokes are mainly round, and the circle is round and square, which makes the circle lively and interesting.

3. The balance and symmetry of seal script, spatial division and balance and symmetry are the unique charm of seal script. Symmetry exists not only in left-right symmetry and up-down symmetry, but also in local symmetry of characters and left-right oblique symmetry of circular strokes.

4. The seal script is tight and loose. The main part of seal script is mostly in the upper part, and the lower part is telescopic foot. Of course, there are also characters with no feet below. The main strokes are in the lower part, and the upper strokes can be raised.
