Running script is developed and originated on the basis of regular script, which produces a font between regular script and cursive script to make up for the slow writing speed of regular script and the fuzziness of cursive script. "Go" means "go", so it is not as scribbled as cursive script, nor as straight as regular script. Whether it is cursive or cursive in essence. Those with more patterns than grass patterns are called "running patterns", and those with more grass patterns are called "running grass".
