Definition Description Calligraphy is vigorous and powerful, and the brush strokes can almost penetrate the back of the paper. It also describes poetry as profound in conception and concise in words.
The source is Tang Yan Zhenqing's Notes on the Twelve Meanings of Zhang Changshi: "When using the front, I often want to make it pass through the back of the paper, which is very successful."
Write the example first. (Yi "Ou Bei Shi Hua" Volume 6)
(of calligraphy) vigorous and powerful.
The "force" in calligraphy and painting is an abstract expression of pointillism, linearity and the author's inner spirit. Specifically, if you can stroke in the center, that is, when you stroke, the bristles are evenly scattered and the pen center walks in the strokes. The force of the arm can be cut into the paper through the soft nib. If the bristles are twisted or twisted into a ball when writing, the bristles are not properly adjusted and spread evenly, and the bristles sweep across the paper like paint, it is called "force-penetrating paper back". Such strokes are "smeared", like ink pigs, and the brushwork is impossible. The strength of brush strokes has nothing to do with the thickness of lines, but the key lies in the author's ability to control the brush and write with the center.
From Chu Suiliang's Preface to the Big Wild Goose Pagoda, we can see that there are many tiny strokes, delicate and powerful. From Yan Zhenqing's "Yan Family Temple Monument", we can feel the dignity of the writing brush, which is like an iron hook and a silver painting. These are all examples that run through the back of the paper.
