Reason:
First, it is to add color and add the finishing touch. Calligraphy is different from painting. There are no colorful colors, it is just "black words on white paper". Its artistic formation is black flowing lines with a single color. In black. A little vermilion here and there enlivens the atmosphere, adds color to the calligraphy, and adds the finishing touch. ?
Second, adjust the focus. When calligraphers create calligraphy works, due to the influence of factors such as environment, mood, calligraphy content, pen and ink, paper, etc., it is impossible for every work to be reasonably laid out, stable and balanced. However, there are indeed superb points in other aspects, which require some reasonable remedies such as improvement, righting, and downward movement to achieve balance and stability. ?
Third, it is to gather energy at the edge. For example, the border seal is a seal placed on the side of a calligraphy work, which plays the role of blocking the edge and gathering energy. The corner seal is stamped on the corner of the calligraphy work. The one on the upper right corner is called the first chapter, and the two lower corner seals are called the corner seal. The corner stamps can be used on both sides and close to the corners, playing the role of "blocking the edges and sealing corners", "filling the void" and adjusting and stabilizing the picture.
Extended information
Looking at the evolution and development from practical seals to seal cutting art, it can be seen that the reason why seal cutting can become a unique art form is first of all thanks to China The nourishment and support of traditional culture.
It is precisely because of ancient China’s mature political system and profound academic thinking that practical official and private seals have been endowed with a series of rich connotations such as hierarchical order, flexibility, exquisite production, and reverence for characters.
These are the cultural supports for seal carving to become an art. Chinese culture has been passed down for thousands of years. The use of Chinese characters is an important factor that cannot be ignored. In the continuation and evolution of Chinese character culture, the role of seals is even more significant and cannot be underestimated.
Like calligraphy, seal cutting is also an art that uses the shape of Chinese characters as its expression object. Every nation in the world has its own writing, but only the Chinese have sublimated practical writing into an artistic activity; similarly, many nations in the world use seals, but only the Chinese have transformed practical seals into the art of seal cutting.
The secret lies in the fact that, in addition to the natural advantages of the pictographic and ideographic characteristics of the Chinese character form itself, the Chinese people are particularly good at understanding, discovering and refining artistic value from daily life.
In particular, ancient Chinese literati were often able to incorporate their perceptions and understanding of nature, society, and life into their daily behaviors, and express their life attitudes and aesthetic pursuits in various ways. It should be said that this is a kind of brilliant, harmonious and natural wisdom, and it is also a valuable contribution of Chinese culture to world civilization.
