Running script originated from regular script and is a font between regular script and cursive script. It came into being to make up for the slow writing speed of regular script and the illegible cursive script. "Line" means "line", so it is not as scribbled as cursive script, nor as correct as regular script. Whether it is cursive or cursive in essence. Cursive script is more called "running script" than cursive script.
The cursive script is characterized by simple structure and continuous strokes. It was formed in the Han Dynasty and evolved on the basis of official script used for simple writing. It can be divided into Cao Zhang, Modern Grass and Crazy Grass. Cao Zhang is one of the traditional calligraphy styles. It is an early cursive script, which began in Han Dynasty and evolved from cursive script to official script. Cao Zhang is the predecessor of "Cao Jin", and the main difference with "Cao Jin" is that he keeps the brushwork of official script, and the upper and lower characters are independent, so there is no continuation. Cao Jin adapted to a development trend and physical changes of official script on the basis of inheriting Cao Zhang. It belongs to the most indulgent cursive script, with rounded strokes and wild and changeable fonts. On the basis of this grass, it is linked to form a "book", which is in the same strain as this grass in composition.
Official script, also called Han Li, is a common solemn font in Chinese characters. Its writing effect is slightly wide and flat, and the horizontal painting is long and the vertical painting is short, showing a rectangle, paying attention to "silkworm head and goose tail" and "twists and turns". Lishu originated in the Qin Dynasty, formed by Cheng Miao, and reached its peak in the Eastern Han Dynasty. Calligraphy is known as "Han Li Tang Kai".
The reason why these three kinds of calligraphy are described according to Kai, Xing, Cao and Cao respectively is because they are closely related, but they are common fonts in the Han Dynasty, thus gradually eliminating the trouble of later writing. Official script is generally straight and square in structure, and several strokes are relatively fixed, which determines the unchangeable form of Chinese character writing. Transform the radicals of compound words to make them fixed and unified. For the sake of neatness and convenience of writing, official script defines the unique characters used as radicals as radicals with special forms, and at the same time fixes many seal scripts with different original radicals into the same radical, such as English, Fan, Mo, Zhen and Dian. The original seal character base is different, and the official script is unified as the "big" base. Another example is the words "Tai", "Qin", "Chun" and "Feng", which were unified into the prefix of spring only after the official reform. This makes official script easier to remember and write than seal script, and adapts to the requirements of the growing times. In the use of pens, there are both squares and circles, and the methods of hiding front and exposing front have the following characteristics: in the form of strokes, there are the characteristics of swallowtail of silkworm head, and the long horizontal paintings have silkworm head, wave potential, pitch and tail; Physically, it is a change from vertical potential to square potential and then to flat horizontal potential; Structurally, China's official position is tight, and his strokes spread to the left and right, showing a symmetrical "eight-character shape", so it is called "eight points" by Han Li. Official script is a simplification of seal script, which is developed from seal script. Writing is like sitting, walking is like walking, turning a circle into a square and turning an arc into a straight one, which is the sublimation of official script.
They are running script, regular script, cursive script and official script.
