The writing method of stippling in official script is obviously different from that in seal script. The points in seal script can be summarized into three types: point, straight and arc, and eight strokes in the eight-law-forever character have developed into official script. In terms of strokes, seal script is mostly round, while official script has always been used by Fiona Fang, and the thickness of strokes has changed.
The acupoints of Lishu are different from the middle point, the upper point, the left end point, the right burning point and the horizontal point. The middle point is written as falling behind the pen, raising the pen against the wind, returning the pen to the right and returning to the apex, and stopping writing. The difference between official script and seal script is that one side has changed.
