The writing method is as shown in the figure below:
After Qin Shihuang unified China, Xiaozhuan implemented the policy of "writing with the same text and carts with the same track" and unifying weights and measures. Prime Minister Li Si was responsible for it. On the basis of the original seal script, Simplified Chinese characters were eliminated, and the other Six Kingdoms characters were eliminated, creating a unified Chinese writing form. It remained popular in China until the end of the Western Han Dynasty, when it was gradually replaced by official script.
But because of its beautiful font, it has always been favored by calligraphers. And because its strokes are complex, its form is ancient, and twists and turns can be added at will, seals were carved in seal script, especially official seals that required anti-counterfeiting, until the fall of the feudal dynasty and the emergence of new anti-counterfeiting technology in modern times.

Characteristics of Xiaozhuan:
1. It is rectangular, with one and a half characters in square regular script as the measure, one character as the main body, and half characters as the vertical feet. The approximate ratio is 3: Around 2.
2. The strokes are horizontally and vertically, evenly rounded, and basically the same thickness. All horizontal and vertical paintings are equidistant and parallel, and all strokes are mainly circles, with circles rising and closing, circles within squares, and squares within circles, making the circles flexible and interesting.
3. It is balanced and symmetrical. The balance and symmetry of space division are the unique charm of seal script. Symmetry not only exists in left-right symmetry and up-down symmetry, but also exists in the local symmetry of the characters and the symmetry of the left and right inclinations of the arc-shaped strokes.
4. It is tight at the top and loose at the bottom. The main part of most characters in Xiaozhuan is in the upper half, and the lower half is a telescopic hanging foot. Of course, there are also characters with no feet at the bottom. The main strokes are in the lower part, and the upper strokes can be raised.
