4. The strokes are different.
Regular script pays attention to straight pen, which is very complicated to use. In addition to oblique strokes, starting and closing the pen need to pause, especially at the turning point, even if it is a very simple word.
However, the running script usually takes the pen out of the pen and adopts the method of leading the pen into the paper. In addition, the running script turned many folding pens into circles, and no pens were used at the turning point.
