Viewpoint: structurally, the left is high and the right is low. The above is a cursive prefix, which consists of four strokes. From left to right are horizontal stippling (the first stroke), vertical stippling (the second stroke), vertical stippling (the third stroke) and horizontal stippling (the fourth stroke). This cursive script can be written in the order of ordinary cursive script, that is, write the second stroke first, then the first stroke, then the fourth stroke, and finally the third stroke. Note: The second half of the third sketch in cursive script is very close to the second sketch, and the tail is hooked out and extends under the second sketch, such as touching a stone with your hand. The third and fourth strokes form a "human" shape. Below the cursive script, there are two stipplings deformed by two characters, and the first point is located directly below the first picture in the cursive script. The second point connects the next sketch. After skimming, there is a vertical painting, starting from the midpoint of skimming and ending at the lowest point of the word. The right side of this vertical graph is closely connected with four short horizontal graphs inclined to the upper right. The vertical distance between the last short horizontal graph and the horizontal line where the lowest point of the word is located is equal to the distance between this short horizontal graph and the previous short horizontal graph. The strokes of the word "sword" in the right half are staggered. The left vertical, the lower left vertical and the right vertical are inclined, and the thickness of the right vertical is twice that of the left vertical. There are three short horizontal paintings between the left vertical and the right vertical, in which the first short horizontal painting is horizontal, connecting the left vertical and touching the right vertical; The second short horizontal painting inclines to the upper right, and then returns to the lower left to bring out the third horizontal painting without touching the right vertical; The third short horizontal painting is parallel to the second short horizontal painting, connecting the left vertical and touching the right vertical. The penultimate stroke starts from the right end of the third short cross, goes to the lower left, and stops near the lowest point of the word. This sketch forms a triangle with the short horizontal view and the left vertical view in front. The last vertical bend hooks the pen at the intersection of the left sketch and the short horizontal sketch in front, and the bottom is higher than the end of the left sketch in front.
