The Eight Methods of Yong Zi are the rules for using brushes in Chinese calligraphy. Taking the order of the eight strokes of the word "Yong" as an example, the method of writing in block letters is explained: the point is the side, the side edge is steep, the stroke is spread out, and the stroke is full; the horizontal direction is the rein, the paper is dropped against the edge, and the edge is slow and sharp, Don't follow the edge of the pen and pass it flatly; a straight pen is a force, and it should not be too straight. If it is too straight, it will be stiff and weak, but it must be straight to see the curve; the hook is a tì (tì), hold the pen at the front, and concentrate the force on the tip of the pen; raise the pen The horizontal stroke is a strategy, the stroke is the same as the straight stroke, and the strength is at the end of the stroke; the long stroke is a sweep. The starting stroke is the same as a straight stroke, the stroke is slightly thicker, and the force must be delivered; the stroke is short to peck, and the stroke is drawn to the left, fast and sharp; the stroke is stroke, the stroke is made lightly, and the folded stroke is laid out slowly, and the closing stroke is important to be subtle . According to legend, it was passed down by Zhiyong in the Sui Dynasty, and one theory is that it was created by Wang Xizhi of the Eastern Jin Dynasty or Zhang Xu of the Tang Dynasty. Because it is the basic rule for writing regular script, later generations also introduced the Eight Methods as the name of calligraphy.
