Running script, also known as "Chinese character running script font", is a running script font that emphasizes the writing style (rules) of regular script, which is freer than regular script and more regular than cursive script. In other words, it is a practical handwritten font based on regular script, which simplifies writing strokes, enhances writing tape, expresses writing interest to speed up writing appropriately, and slightly changes writing order, and has strong characteristics of easy recognition and easy learning.
