Taking the eight-stroke sequence of the word "Yong" as an example, this paper expounds the method of writing in block letters: the point is the side, the side front is steep, and the strokes are placed horizontally, which is enough to close the front; Cross for fun, against the front of the paper, slowly rushing back, not flat with the front; Straight pen is an effort, not too straight. Too straight will be stiff and weak, but it must be straight and look at the curve; The hook is a pin (t √), and the front end of the pen is raised to concentrate the force on the nib; Raising the horizontal is the strategy, the stroke is straight, and the effective force is at the end of the stroke; Long left for the prey, straight strokes, slightly fat front, force to send; Short skimming is pecking, writing left, fast and sharp; Writing is true (philosophy), falling lightly against the trend, slowing down the front, and focusing on subtlety.
Legend has it that it was created by Zhiyong in Sui Dynasty or Wang Xizhi in Eastern Jin Dynasty or Zhang Xu in Tang Dynasty. Because this is the basic rule of writing regular script, later generations also call these eight methods calligraphy.
