The eight methods of "Yong" are the writing techniques used by ancient calligraphers to practice regular script. The character "Yong" has eight strokes: dot, horizontal, vertical, hook, upward and horizontal, left, oblique, and na. According to their respective strokes, the eight characters can be summarized as side, le, crossbow (also known as Nu), 误, ce, and sweep. , peck, knock. These eight strokes are the basic strokes of regular script. Each stroke has its own characteristics, but they echo each other and are completed in one go. For example, Li Puguang's "Xue'an Eight Methods" said: "The beauty of the Zeng method lies in the danger of crossing three times to reveal its power." If the character "Yong" can express the spirit of each stroke, regular script can be considered to have reached a considerable level.
