During the development of seal cutting, some ancient seals experienced great changes, natural patina and wind erosion, and the seal surface was incomplete, damaged, and blurred. Then a unique and interesting artistic effect appeared. Wu Changshuo, a modern seal-cutting master, introduced the field of seal-cutting after seeing the inscriptions on clay seals. He deliberately pursued the interest of broken patterns and unique charm, and gradually became popular in the seal world. The dilapidation of nature or man-made has a unique charm of vastness, simplicity, clumsiness and elegance. It has a unique beauty that cannot be tolerated by neatness and cleanliness, which is fascinated by Indian people. Paying attention to the contemporary Indian world, "broken" has been valued and used by more and more Indian people. Damage is divided into internal damage and external damage. Internal damage can refer to the damage to the radical strokes of the text, the seal surface and the inner column; external damage refers to the damage to the outer column, and the broken corners can be regarded as a special case of broken edges. The function of fragmentation is to provide ventilation and avoid the shortcomings of similar strokes, which can be compensated by fragmentation in order to achieve the maximum artistic effect. Internal breaking and external breaking are sometimes used alone, sometimes together, depending on the specific situation. Damage can be artificial. For example, Chen Hongshou, one of the eight masters of Xiling, often placed a newly carved seal in a wooden box and asked the book boy to shake it and hit it to break it, in order to achieve unexpected miraculous effects. They can also be obtained by chance, often exceeding the author's original idea and receiving unexpected interest. For example, because the stone is loose, large pieces fall off during the engraving process, or the knife is pushed too hard, or the stone is too hard. A small mistake or a knife mark sliding to one side may occur. Contemporary seal cutting creations are mainly based on the former. The carving knife is a seal carving creation tool. The carving is accomplished by swinging the knife, chopping the knife, scraping, grinding and striking with the knife bar, or dotting the sealing surface. Seal cutting mainly obtains beauty through visual aesthetics. To put it bluntly, it is the four-character scripture of "balanced contrast". "Contrast" refers to the contrast between red and white, and the red cloth and white are reflected on the seal surface. It is necessary to maintain the unity and transformation of the two opposites and lead the balance between virtual and real. Therefore, the role of the broken is to create a balanced transformation of opposites. Generally speaking, it is a requirement of the constitution, but it also involves When it comes to calligraphy and knife skills, it is especially accomplished with the help of knife skills, so it does not belong to any one of the three methods. 1. Internal breakdown: ① Echo. ② Avoid similarities. ③Contrast. ④Leave blank. ⑤Guan Qi. ⑥Dot. 2. External breaking: External breaking and internal breaking have the same effect, and there are the following situations: ① Breaking one side. ② Breaking the double sides has two purposes: one is to use the strokes as sidebars, and the other is to maintain the balance of the printed surface. ③Break three sides, the shape is scattered but the spirit is not scattered. ④ Break the four sides to form a state without sidebars. Boundless seal is a common form in today's seal world. The key is to have full energy and energy, not to be thirsty. ⑤ Specially break the bottom edge. This is a special case of breaking the edge. Compared with the other three sides, the bottom edge plays an important role in balancing the center of gravity and retaining the breath. Therefore, you must be cautious when breaking it. Breaking it randomly can easily cause deflation. However, if you are good at breaking it, it will not leak, but will make the breath full and melt. Decay into miraculous effects. The first premise of seal cutting is that the text can be read. Blindly mutilating it, using a knife to hurt the mind and losing the shape of the characters, especially for some seal scripts that only have subtle differences, result in the corruption of characters, which is considered an illegal operation. In the final analysis, being broken is just an auxiliary means of compensation. If it is too deliberate, it will eventually become a failure and it will be difficult to reach a high level. How to break a small space, you have to be bold and careful, and not all seals need to be broken. Generally speaking, broken parts are used more in freehand seal cutting. In Yuan and Zhu inscriptions that are neat and tidy, broken parts must also be paid attention to in order to achieve various changes. Not every line in Yuan and Zhu inscriptions must be as smooth as new. break. For works by famous artists that were damaged due to mistakes or accidents, or even those in the Han Dynasty that were damaged or lost, we should not copy them in a literal way. We should rely on our artistic discernment to use our brains to modify them, and the damage should not be self-defeating or superfluous, which would be counterproductive.
