What kind of brushwork is cone painting sand?

Tapered sand painting is a so-called "flat" pen technique, which means that when lifting a pen, the force is even, the head and tail are clear, and the pen is impartial and not picky. Drawing sand with an awl has the effect of "hiding the front", while the sand on both sides is flat and convex with positive marks, which looks like a "center", so drawing sand with an awl is a metaphor for the roundness of book traces.

The lines drawn by this pen method are considered by the ancients to be the purest, purest, most aesthetic and most tasteful lines. "Leak mark" is a vivid metaphor for the brushwork and artistic effect of horizontal and vertical, even force and hidden front. When writing, the pen tube should fall down together, and the pen tip should run around in frustration, just like the water drops leaking from the house slowly trickling down the mud wall and winding down to bet, forming a bulging semicircle. The brush strokes are round, lively, thick and full, with a sense of three-dimensional, heavy and flowing.

"Yin Yinni" and "painting sand with a cone" have similar meanings, both of which involve the brushwork of "center". "Yin Yinni" refers to putting a seal on the mud of an article (as a seal). When stamping, only by pressing the seal vertically in the middle of the stamp pad will the stamp pad naturally overflow to both sides along the center of the line on the seal.

When the awl is used to paddle the sand downward, only when the direction is positive and the force is applied vertically downward, the sand on both sides will naturally rise and a groove will appear in the middle. So is calligraphy. In order to make the ink full and powerful, it is necessary to make the nib perpendicular to the paper and move forward in the middle of stippling, which are two characteristics of the "center" pen. Cai Yong said: "I often let the pen tip move in stippling."
