Li Shu, including Qin Li and Han Li, is generally believed to have developed from seal script, with wide and flat font, long horizontal painting and short vertical painting, and paying attention to "swallow-tailed 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".
Braille writing of official characters:
There are two kinds of horizontal bodies in Lishu: short horizontal body and long horizontal body. The short horizontal style starts from the pen and ends in the flat, and the horizontal style protects the tail, which is slightly like seal script. A long horizontal pen hides the front face upwards, and then turns right with Fang Bi, which becomes a silkworm pen.
Then write to the right, the pen is slightly astringent and can't slide. When you press the pen to two-thirds of the horizontal position, it will bring out a downward wave notch, and then lift the pen slightly upward to form a dovetail. This kind of stroke is also called wave stroke.
Si is similar to long horizontal writing, but the strokes are down to the right, which is more stretching than horizontal writing. Skimming is written in the same way as writing on the left and picking on the left. After starting the pen, use the pen to write down to the left, slightly increase the bending potential in the line, until the pen is forced to stop at less than two-thirds of the whole painting, twist the pen at the end of the painting, and slightly lift it to the left to make the pen return to the front of the line.
There are several ways to write hooks. Only the commonly used long hook writing is introduced here. After the stroke, we don't mention it, but use the pen to stroke down. When we reach the lower end of the shaft, we draw an approximately horizontal arc to the left in turn, and then lift the pen to the end of the arc.
In addition, the writing of official script should also pay attention to the following points. If there are several horizontal overlaps in a word, usually the last horizontal is written as dovetail and silkworm head, and the rest are short horizontal. For example, there are both long lines and long lines in a word. Generally, swallowtail silkworm heads are used in the long cross, not the long cross. For example, the word "big" is written as "big".
If the horizontal line is surrounded by other strokes, the horizontal line writing does not use the silkworm head dovetail. In other words, the first word of swallowtail silkworm can only appear once, otherwise it will affect the beauty of the word, so the predecessors said, "Silkworms have no two colors, and swallows can't fly in pairs."
