Running script originated from regular script, but compared with regular script, there are obvious differences. As far as lines are concerned, the strokes of the pen are regular and clear, while the strokes are flexible and freely retractable, with more arcs than straight lines. As far as the structure is concerned, the model's structure is standardized and upright, and the lines can be correct or correct, big or small, and the changes are not limited. As far as rowing speed is concerned, rowing speed is slow, while rowing speed is fast and hearty. In addition, the running script also absorbs cursive calligraphy, often replacing complexity with simplicity and replacing square folding with circle, which strengthens the echo and coherence between words. Therefore, the running script is characterized by regular script, clever cursive script and rich brushwork. Sometimes, the winger cooperates with the center to gain an advantage by exposing the striker on paper, and sometimes, Fiona Fang combines concealment and exposure, combining rigidity with softness. Running script pays attention to the momentum of writing, the effect of writing, the echo of starting and putting pen to paper, and the clarity of starting and putting pen to paper, all of which are important characteristics that distinguish running script from regular script. In addition, the running script has strong compatibility, such as the flying and elegant modern grass, the vigorous and concise Cao Zhang, the magnolia in Weibei, the steady and agile official script, and the elegant and even seal script. Running script is very good at using and expressing, and has gradually formed its own style characteristics. The main reasons why running script is different from regular script are as follows: first, due to the intervention of cursive script, running script often omits and transforms the writing methods of some radicals in regular script; Second, for the convenience of writing, running script often changes the original writing order of regular script and forms its own unique style; Thirdly, the running script often adds a continuous and guiding technique between stippling and stippling, producing some ties and connections, forming its own personality characteristics of connected veins, emotional flow and liveliness.
