Yan Zhenqing said in "The brushwork of returning Zhang Changsheng": "I paint with sharp edges (on the shaping) and write them, which is dangerous, bright and charming. From then on, I learned to use a pen to "draw sand with a cone" to hide the front and draw calmly. When I use a pen, I often want it to pass through the back of the paper. This is extremely successful. "
Based on the textual research of the previous paragraph "Painting sand with a cone", this paper analyzes the origin of seven lines related to the Manuscript for Sacrificing a Nephew and Shaping Painting a Book with a Cone, and draws the following statement: 1. With the brush strokes of "painting sand with a cone", I feel calm, but my mood is particularly strong. 2. "Tapered sand painting" is a kind of pen hidden in the front of the pen body. When the house is in the center, the front of the pen body spreads out. The hair of the house should be as close to the paper as possible, and most pens without paper should be gathered (that is, the hair of the pen is smooth), and the front is mainly convergent, otherwise it can't be in the shape of points. 3. Because the middle of the edge of the "cone painting sand" line is strip-shaped, the force reaches the front tip, and the paper is killed into the house, and the downward pressure is great; The pen has a good grip and makes full use of the flexibility of the pen; There is a forced horizontal force that lives with the pull back force. In order to prevent the front from spreading, the nib must be twisted. The house pole should rotate, and its trend should be straight and dark, or the bright curve should be straight. Only with "not really horizontal" curve can we turn, and only with turning can we change the flow potential. Use the gesture (posture) of "painting sand with a cone" to help the flow. 5. Because "Painting Sand on the Cone" uses dry ink, the friction is large, and the lines are calm and dignified, so it can be seen that Xu Shi is used. 6. "Tapping sand" is not a "dry pen" for the following reasons: 1. "Dry pen" appears occasionally, and "cone painting sand" appears in a large area; Second, the texture of "dry pen" lines is dotted, while "cone painting sand" is mainly dotted; Third, "dry pen" can support illness and threats, but "painting sand with a cone" can't; Fourthly, "dry pen" is made of strong ink and dehydrated water, which is called "ink painting", while "cone painting sand" is made of dry ink and transported to home, so it is called "brush painting". 7. "Tapered sand painting" is not a "missed mark". The reasons are as follows: first, "leak marks" use less ink than "cone sand paintings"; Second, the lines of "leakage marks" are all black, unlike "cone painting sand", which leaks white in a large proportion; Third, the "roof leak" has a greater pull back than the "cone drawing copy", just like the "roof leak mark" with mud in the water, which is stagnant. It can be seen that it is inappropriate for Yuan Xian to confuse the two. 8. The "cone painting sand" technique of pen calligraphy is different from that of brush: for steel houses, the paper surface is required to be rough, or the rubber pad is preferably flat and hemp-like, while the brush has no choice between paper and pad, which is one of them; The nib of the steel house should be ancestral, and the direction of force is not mainly downward pressure, but mainly horizontal direction, while the brush is "like a bald pen" for the pen, and non-bald pens are acceptable, and the pressure in the direction of force is greater, which is the second; The "cone painting sand" of steel houses should adopt "flowing trend" and "rapid trend", and the brush is so huge. This is the third: it can be seen that some calligraphers say that "there is no difference between hard pen and soft pen", which is not enough.
The source of the leakage is Huai Su and his brothers, who often follow the brushwork of children. Tong said, "Call Tong privately and say,' I feel strange when I fly alone in the sand'. The sage of grass is here." Yan Zhenqing said, "Is the teacher complacent? Sue said, "I have seen many strange peaks in Xia Yun, so I need to learn from them often. Its pleasure is like a bird flying out of the forest and a snake jumping into the grass. It is natural to encounter the road to the wall again. " Zhen Qing said, "Why is it like a leak?" Su Qi shook hands with the public and said, "I see." ("shihuaisu and Yan Zhenqing on cursive script")
Yan Zhenqing and Huai Su both mentioned "leak marks" in their essays. It means that the center uses a pen from top to bottom, naturally winding down like a leak, not vertical and straight down, and rigid. To understand the leak marks, we must first talk about ancient buildings. "In ancient times, it was usually a hut. When it rains heavily, it leaks from the side wall. It didn't rush to the end like the water in the tap, but slowly descended. The accumulated points flow downwards in a line, so this dignified line is called a leak mark. "
As for the "missing mark", it is all in one word "mark". The line of the mark is not a stroke to the end, but a vertical stroke, through which the mark passes. Cheng Shifa believes that pen and ink should not be too accurate, but should be gathered together at an appropriate time, and lines, that is, in the process of "painting sand on the cone" and "leaking marks", have formed vitality, which comes from setbacks. Not many people in calligraphy and painting know about setbacks. Such as articles, articles seem to see mountains rather than peace.
